50 Years of Scientific Evidence for the Existence of Bigfoot
50 Years of Scientific Evidence for the Existence of Bigfoot
You’re talking about a Yeti, or Bigfoot, or Sasquatch…
I’m SURE that they exist…British scientists have found…
Yeti hair…They don’t match up with the DNA cells
from (any) known animals .”
Doctor Jane Goodall, on National Public Radio, September 27, 2002, world’s foremost authority on chimpanzees.
“You can’t fake DNA evidence…the nuclear genome seems to have
human and nonhuman sequences…Sasquatch is REAL, as proven
by (DNA) genetic analysis…The genome has some good, human
matches and some unknowns…with sequences that match nothing.”
Doctor David Swenson, Ph.D., biochemist with Green Resources Redux, Inc., 2013.
Frame 352 of the Patterson-Gimlin film, alleged to depict a female Bigfoot, shot on October 20, 1967, by Bob Gimlin.
Bigfoot Caught on Film in 1967 In a California Canyon!
The greatest and most-famous, Bigfoot incident of all time took place on October 20, 1967, along Bluff Creek, California, when Roger Patterson and Robert “Bob” Gimlin rode on horseback down into a canyon in a national forest, carrying a Cine-Kodak K-100 16mm film camera, at about 1:30 PM, in search of any of the Bigfeet sighted in that same area the previous year. They were both taken by surprise when they came upon a tall creature just 25 feet (7.6 meters) away, and Patterson dismounted and began filming for 59 seconds as the creature was 80 to 120 feet away.
They estimated the creature’s height at 6.5 to 7.5 feet (2 to 2.3 meters), and its weight at 350 pounds (159 kilograms), and later made two plaster casts of the 16-inch (41-cm) footprints. The creature had a 41-inch (104-centimeter) average stride, which increased to 65 inches (165 centimeters) as she sped up. By comparison, this author is 6 feet and one inch (1.85 meters) tall, has a 27-inch (69-centimeter) stride in normal walking, and a stride of 48 inches (122 centimeters), when I’m in a very big hurry. Gimlin later noted that, “ The horse never made tracks as deep as the creature did, so…she was a heavy, well-muscled creature.”
It’s an absolutely amazing film by any standard, depicting a very tall, very muscular, humanoid, female creature in full motion, walking briskly away from the camera and glancing back just once (most-famously at Frame 352, which is now in the public domain.) Both men have consistently denied any allegations of a hoax , and no one has ever been able to prove the film to have been faked in any manner.
“Toward a Resolution of the Bigfoot Phenomenon,” usually just called the NASI Report, used detailed, forensic, computer analysis to examine the Patterson-Gimlin film great detail.
The Patterson-Gimlin Film Was Analyzed In Every Way
In 1998, the North American Science Institute (NASI) of Hood River, Oregon, issued a formal report entitled, “Toward a Resolution of the Bigfoot Phenomenon,” usually just called the NASI Report, after having used detailed, forensic, computer analysis to examine the controversial film in great detail. They stated, “ The 1967 Patterson - Gimlin Film ( PGF )… converted to digital data via a film scanner so that the imagery could be processed by computer.The computed height of the subject in the film is 7’ 3 1/2”. If the subject was a person wearing a costume... a seam or interface in the costume would be detected. No seams or interfaces were detected .”
“Subject’s hand (and foot) appears to be between that of the gorilla and the human …The appearance and sophistication of musculature as seen in the Patterson-Gimlin film has not yet been reproduced in costumes for the entertainment industry…The film subject is not employing typical, human locomotion…while the stride can be duplicated, the continuous, forward motion seen in the film cannot…To date, the Patterson-Gimlin film has defied explanation…after three years of rigorous, forensic examination…(the) film is of an uncatalogued animal…the Patterson-Gimlin film cannot be demonstrated to be a forgery.”
Distinguished anthropologist Doctor Grover Krantz of Washington State University concluded in 1999 that, “I fully accept the Patterson film…consistent with a 500-pound biped. I’ve attempted to imitate it, and I really can’t do it…The (subject’s) knee is regularly bent at more than 90 degrees, while the human leg bends less than 70 degrees.” In fact, no human being has ever replicated this extreme, lower leg lift while maintaining the smoothness, posture, and stride length of the creature on the film.
Doctor Jeffrey Meldrum, Professor of Anatomy and Anthropology at Idaho State University, has also analyzed the Patterson Film: “The film subject possesses arms…disproportionately long for its stature… Anthropologists typically express limb proportions as an intermembral (IM) index…an IM index somewhere between 80 and 90 (actually, 84 for Bigfoot), intermediate between humans (72) and African apes (122)…is well beyond the mean for humans, and effectively rules out a man-in-a-suit explanation…Let there be no confusion about it. The PGF shows a real, giant ape-woman in the wild.”
Doctor Dmitry Donskoy, Chief of the Department of Biomechanics at the Russian Central Institute of Physical Culture, and later associated with Moscow’s Darwin Museum, concluded that the Patterson film creature was “a very massive animal that is definitely not a human being,” because its smooth gait cannot be replicated by any human.
Author Ivan T. Sanderson added that, “The Patterson film…is…the only footage I have ever seen with very real, flawless motion…beyond the level that Hollywood movie-makers were using at the time…to walk in such a way that to this day it cannot be replicated…Dale Sheets, head of the Documentary Film Department (at Universal Pictures)…(said) ‘Maybe if you allotted a couple of million bucks, we could try, but we’d have to invent a whole set of new, artificial muscles, get a gorilla’s skin, and train an actor to walk like that…it would be nearly impossible.’”
John Chambers, the Oscar-winning, costume designer for “Planet of the Apes,” filmed in 1968, later said of the PGF film: “If this is a suit, it is the finest ever devised, for it was beyond our capability in the 1960s. Every hair would have had to have been individually attached to the model for this to do what it does in the (PGF) film.”
In 1984, The Sasquatch and Other Unknown Hominoids was published, a 335-page compilation of scientific papers, edited by Yugoslavian-born, Russian hominologist Vladimir Markotić (with a Ph.D. in Anthropology from Harvard University, and Associate Professor Emeritus of Archaeology at the University of Calgary), with introductory comments by Doctor Grover Krantz. Chapter 5 (14 pages) is entitled, “Analysis of the Patterson-Gimlin Film: Why We Find It Authentic,” by Dmitri Bayanov, Doctor Igor Burtsev (Russia’s foremost authority on the Yeti), and René Dahinden, a world-renowned expert on Bigfoot/Sasquatch:
“We have subjected the film to systematic and many-sided analysis both in its technical and biological aspects…The film has passed all our tests and scrutinies…who other than God or natural selection is sufficiently conversant with anatomy and bio-mechanics to ‘design’ a body which is so perfectly harmonious in terms of structure and function? Here we confidently give this verdict: The Patterson-Gimlin movie is an authentic documentary of a genuine, female hominoid, popularly known as Sasquatch or Bigfoot.”
So, not only is the Patterson-Gimlin film definitely NOT a hoax, but virtually everyone, including the BBC in 1998, who have tried to demonstrate how it was done, have failed miserably, and BBC was forced to apologize to the Bigfoot Research Organization (BFRO.) On the contrary, EVERY SCIENTIST who has studied the Patterson Film has either stated that it shows a real, unclassified species, or that a conclusion cannot be made.

In 2002, a severed hand was delivered anonymously to a police station in Butte, Montana. The local coroner took X-rays, examined it, and concluded that it was not human. The police took the hand to Bigfoot researcher Don Monroe of Spencer, Montana, who showed it to several scientists. No one could identify it as human. In 2006, Monroe gave it to Bigfoot researcher Tom Biscardi, who had it tested by the DNA Diagnostics Center of Fairfield, Ohio, in May 2006. The official result was: “Not human. Not any known primate. Not even in the system.” This was the first confirmed, DNA testing of any Bigfoot or Sasquatch forensic evidence.
On August 14, 2006, Scott Mosbeck discovered blood, tissue, strange hair, and a bloody, 18-inch (46-centimeter) footprint on a “screw board” (a nasty and illegal booby trap) outside his remote cabin at Snelgrove Lake, Canada, and he called Doctor Jeffrey Meldrum (Idaho State University) and Doctor Curt Nelson (University of Minnesota) to the scene. The hair appeared human, but had no medullas, and did not match any primate known to science, or any other known animal!
Doctor Nelson said that “The DNA says primate, but not quite human and not quite non-human (chimp/ape)…it was identical to human DNA (99.5-percent), except it had one nucleotide polymorphism…a difference that is shared with chimpanzees…I knew that I might be looking at the DNA of a Sasquatch.”
On October 8, 2010, Justin Smeja, age 25, of Sacramento, California, was hunting for black bear near Gold Lake. Instead, he shot and killed two large, hairy, upright creatures, an adult and a child, with his .25-06 rifle. Smeja did not believe in Bigfoot then. He does now.
His neighbor/driver was an eyewitness, and insists that the incident was horrible, disgusting, and true. Smeja kept a piece of the smaller, dead creature, and gave a sample of skin and dark, auburn hair to Doctor Melba S. Ketchum, DVM (a veterinarian), the director of DNA Diagnostics, Inc., of Timpson, Texas, for DNA analysis. Eight separate, DNA labs tested it: “Not human, not any known animal, an unknown primate.”
The evidence for Bigfoot comes in all forms from hair to DNA.
Doctor Ketchum made very exciting news three years later. On February 13, 2013, her groundbreaking, Bigfoot DNA study was finally released, entitled “Novel North American Hominins,” at 63 pages in length. Here are the DNA samples used in the astounding report:
Bigfoot samples submitted: Over 200.
Tested positive for “Unknown Primate” (Bigfoot): 111, tested at 34 different labs .
# of Bigfoot individuals represented: 20 to 28.
Tested positive for “Unknown Primate” (Yeti): 1.
# of Yeti individuals represented: 1.
Details of successful, Bigfoot samples:
5 hair samples from Golden Ears Provincial Park, BC, Canada, five separate creatures.
1 toenail from Larry Jenkins in the Grand Canyon area of Arizona.
1 blood sample from J.C. Johnson in the Four Corners area of New Mexico.
1 blood sample from Crittenden, Kentucky, gathered by the Erickson Project.
1 hair sample from Hoopa Valley, California.
1 hair sample from Larry Surface in southern Ohio.
1 hair sample from Joe Black in the Great Smoky Mountains, Eastern Tennessee.
1 slice of Bigfoot flesh from Sierra Buttes, California, shot dead by Justin Smeja.
1 large sample of saliva from the Olympic Project, Bigfoot licking a camera, 2009.
1 hair sample from SE Oklahoma collected by TEXLA Cryptozoological Research.
1 blood, tissue, and hair sample from “screw-board” trap at Snelgrove Lake, Canada.
These are only 15 of 111 successful, Bigfoot samples.
Details of successful, Yeti samples:
1 Yeti hair sample from “Destination Truth” TV series, collected in Bhutan.
The nuclear DNA of Bigfoot creatures is an evolutionary form somewhere between primates and humans.
Bigfoot DNA Reveals They Are Similar to Us But Not Much
The testing results, independently verified by 34 different laboratories , and utterly impossible to fake, showed that Bigfoot samples tested positive for a single, non-human polymorphism, and the default, genetic hair color was “red” (“auburn,” in current terminology.) The nuclear DNA results were “one-third of the way from a human to a chimp,” or even closer to human. The results did not appear in GenBank, the master, DNA database of all known animals. In other words, according to the Ketchum tests, Bigfoot/Sasquatch is at least 99.7-percent human!
This was fully supported by previous, DNA testing by Bigfoot researcher Richard Stubstad in June 2011, who wrote, “Sasquatch DNA…tested 100-percent Homo sapiens (human, on the mitochondrial side)…No current, GenBank Homo sapiens genomes perfectly match either sample…clearly and unequivocally from the ‘Franco-Cantabrian glacial refuge’…some 15,000 years ago…The only conceivable migration path was…towards the…Asian-North American land bridge…an approximately 99.98-percent mitochondrial DNA match…for both purported, Sasquatch specimens.”
The Franco-Cantabrian glacial refuge, from about 15,000 to 20,000 B.C., encompassed most of southern France and the snow-capped, Pyrenees Mountains. During my PowerPoint presentations on this subject, I used to joke at this point in the discussion, “No wonder Bigfeet are so standoffish and difficult to understand. They’re French!”
These DNA results should really not be too surprising, considering that Cornell University and other noted scientists state that there is only a one-percent difference in the DNA and overall genetic makeup of chimpanzees and humans. Bigfoot DNA samples so far contain only about 600 gene variations, versus 2,000 for chimpanzees, so they are genetically about 99.7-percent to 99.995-percent human! They even have an official, Latin name now, Homo sapiens hirsuti , meaning “hairy humans.”
Washington State animal bones were found with chewing marks that indicated Bigfoot teeth evidence, which left marks two times the size of human teeth.
Chew Marks Left On Animal Bones Are Twice Human Size Marks
Doctor/Professor Mitchel N. Townsend, a leading, Bigfoot expert, wrote for Ancient Origins on April 7, 2021, that, “Is Bigfoot Real? Let’s Look at Emerging, Scientific Evidence: (On) Mount Saint Helens in Washington State. In 2013 and 2014…I located three different, ungulate, rib prey bone assemblages (elk and deer rib bones) that had seemingly inexplicable, chewing marks left in them…Of the 25 total hominin incisor measurements taken from all three sites, 92 percent are…at least two times the size of modern humans. The evidence was clear and consistent across all three locations. After identifying the teeth marks as Hominin, we…were able to estimate mouth size, which again was over double the size of a modern human.
“(It) enable(s) the construction of a currently-unclassified, hominin profile…(with) hominin incisor measurements primarily outside the possibility of Homo sapiens …The conclusions are accurate, well supported, repeatable…of a currently-unclassified hominin living (Bigfoot) at Mount Saint Helens. Once again, we are faced with the central question of why mainstream science has failed to comprehensively examine the possible existence of what some people refer to as Bigfoot. Credible, multi-disciplinary evidence continues to emerge…of a giant, unclassified hominin living and thriving in the Pacific Northwest .
“At the end of the day, why are we still asking the same question: ‘Is Bigfoot real?’ We encourage the scientific community to move beyond their skepticism in order to conduct deep examination…in this emerging area of research. Science has an obligation by definition to explain the unexplained, whatever that may be.”
We are intrigued with the Yeti, both for its scientific importance and for what it says about our own human interests and biases. If the Yeti is an old human-like form that we have driven into the mountains, it seems our current goal is to display them in zoos . . .
Hopefully We Will Not Put Bigfoot On Display In A Zoo!
I’ll conclude this tale of nature, science, mystery, and intrigue with two great, thought-provoking quotes to consider. First, Danish philosopher Søren Kierkegaard (1813-1855) wrote that, “There are two ways to be fooled. One is to believe what isn’t true; the other is to refuse to believe what is true.”
Secondly, noted zoologist and explorer Edward W. Cronin, Jr., of Santa Barbara, California, wrote insightfully in his article, “The Yeti,” in The Atlantic magazine, November 1973 (page 53), that:
“Even though I am intrigued with the Yeti , both for its scientific importance and for what it says about our own interests and biases, I would be deeply saddened to have it discovered. If the Yeti is an old form that we have driven into the mountains, now we would be driving it into the zoos.”
“We would gain another possession, another ragged exhibit in the concrete world of the zoological park, another Latin name to enter on our scientific ledgers. But what about the wild creature that now roams free of man in the forests? Every time man asserts his mastery over nature, he gains something in knowledge, but loses something in spirit.”

In our oceans lie the biggest mysteries of our world. It’s one of the reasons why divers are fascinated with the bottom of the ocean. And it is due to their relentless submerging in the darkest depths of our seas that we have made some of the most bizarre discoveries. These span from shipwrecks that were deemed forever-gone, to entire submerged cities that we didn’t even know about. Stay close to explore with us the 10 most exciting discoveries made by deep-sea divers!
I have long wondered if aliens have ever introduced new species onto Earth. This creature brings back those thoughts. It looks like a snake, it has scales on its mouth area and a long forked tongue, but the resemblance ends there. I have never seen a snake with hair...this one seems to have long hair which is green from algae. This may be the first living proof that aliens are transplanting creatures on our planet. Of course a DNA analysis and hair analysis needs to be done. But...I ask you...have you ever seen a creature like it before in your life? I haven't.
Scott C. Waring - Taiwan
News states:
A local named Tu, 49, first noticed the snake when it slowly moved in the dirty water near his house while he was walking. Amazed by the creature, he took home the snake and kept it in an earthen water jar before showing it to his equally-confused family members. They, too, were baffled by the dragon-like appearance of the animal.

NASA’s spacecraft SWAP 174 captured a huge cylindrical UFO which seemly coming out of the sun on 2022-02-20.
The appearance and disappearance of the UFO happened in just a split second.
NASA scientists explained that such objects are in fact compression artifacts but not everyone is convinced that these objects are just compression artifacts, they suggest that alien civilizations use giant interdimensional spacecraft, which access our solar system through a stargate on the sun.

They will explore Venus using a manta ray inspired spacecraft
Researchers are working on a concept that could change the way we explore the intense environment of Earth’s closest planetary neighbor.
Studying Venus will help us better understand why it harbors such an extreme environment and unlock the mysteries of how planets evolve, including Earth.
A network of tensioning cables are used to actuate the pectoral and pelvic fins (equivalent to wings and horizontal stabilizers of a fixed wing aircraft, respectively). They will furnish articulated flapping flight for achieving thrust, control, stability, and additional lift.
Furthermore, the same tensioning network may be used to provide the mechanical compression required for active buoyancy control. This makes BREEZE an ideal alternate approach to the Venus.
Actually it is a bit strange that they now want to explore Venus with such a manta ray craft, since they already sent in the late 80s and 90s the Magellan spacecraft to Venus which already collected an enormous amount of images that have finally been published by NASA in which huge cities, artificial structures and all kinds of elements that seem to obey constructions appear intelligent effected by some kind of alien race that inhabited or colonized the second planet in our solar system.

The Enigma of Prehistoric Skulls with Bullet-Like Holes
The Enigma of Prehistoric Skulls with Bullet-Like Holes
Nearly one century ago, a Swiss miner was searching for metal ore deposits in the limestone caves of Kabwe, Zambia, when he found a prehistoric skull that dated back between 125,000 and 300,000 years. It was the first fossil to be discovered in Africa with Homo sapiens characteristics.
But there was an even bigger surprise. The prehistoric skull had a small, circular shaped hole on the side, which forensic scientists say could only have been created by an extremely high-velocity projectile, such as that caused by a bullet. The mystery was compounded by the discovery of an ancient auroch skull with exactly the same feature. The discoveries have led to many wild and wonderful speculations, but we are really no closer to solving the puzzle.
Replica of the prehistoric Kabwe skull, housed in Mauer Museum, in Heidelberg, Germany.
Trying to Classify Prehistoric Skulls – The Case of the Kabwe Skull
The skull found in Kabwe (also known as Broken Hill) attracted a great deal of attention when it was first discovered. According to the Smithsonian Institution , it was initially believed that the Kabwe prehistoric skull was the first ever example of a new species of hominid called Homo rhodesiensis .
It was subsequently assigned the classification of Homo heidelbergensis , although more recent research has shown that several characteristics shown similarities to Homo erectus , Homo neanderthalensis , and modern Homo sapiens . Whoever the skull belonged to, it appears he or she may have been the product of interbreeding between different hominid species.
But its unique combination of features was not all that was unique about the Kabwe skull. It was also found to have a small, perfectly-round hole on the left side of the cranium, as well as a shattered parietal plate on the opposite side.
This suggests the projectile that entered on the left side, passed through the skull with such force that it completely shattered the right side. Strangely, the presence of these highly-unusual characteristics are missing from descriptions of the Kabwe skull on the Smithsonian Institution page, as well the Natural History Museum of London, although their photos clearly depict the hole in the skull.
A replica of the prehistoric Broken Hill or Kabwe skull from the Museum in Livingstone, Zambia, with the apparent bullet hole visible on the left.
What Could Have Caused the Hole in the Kabwe Skull?
While it is natural to assume that the hole may have been caused by a high-speed spear or javelin, investigations proved this was not possible. “When a skull is struck by a relatively low-velocity projectile – such as an arrow, or spear – it produces what are known as radial cracks or striations; that is, minute hairline fractures running away from the place of impact,” wrote The Shields Gazette . “As there were no radial fractures on the Neanderthal skull, it was unanimously concluded that the projectile must have had a far, far greater velocity than an arrow or spear.”
According to the book Technology of the Gods: The Incredible Sciences of the Ancients by David Hatcher Childress, a German forensics expert came to an even more radical conclusion: “the cranial damage to Rhodesian man’s skull could not have been caused by anything but a bullet.” Researcher Rene Noorbergen, who investigated the mystery in Secrets Of The Lost Races , concurred, saying that “this same feature is seen in modern victims of head wounds received from shots from a high-powered rifle.”
If this were true, it would mean that a) the skull is not as old as claimed, b) the ancient skull was shot in modern times, c) the ancient skull was shot in ancient times by a technologically advanced civilization. The first and second options are discounted by the fact that the skull was found 60 feet (18.2 m) below the surface, which confirms that it is at least several thousand years old.
It was not located near enough to ground level to have been accidently or intentionally shot in recent decades. Does that just leave us with the third option, or could there be other explanations in the mix?
Auroch skull with bullet-like hole in the forehead.
Before exploring other hypotheses, we must give consideration to another prehistoric skull discovery which further compounds the mystery. Thousands of miles away, along the Lena River in Russia, another ancient skull was discovered with the same clean, round hole.
The skull belonged to an auroch, an extinct species of wile cattle that lived between 2 million and 4,000 years ago. Like the Kabwe skull, the hole in the auroch skull is also missing radial cracks that would result from spear or arrow projectiles.
The prehistoric skull, which is now on display in Moscow’s Museum of Paleontology, could not have been struck by a bullet in more modern times because calcification around the bullet hole shows that the auroch survived the wound for some time afterwards.
The Kabwe skull, or Broken Hill skull, with its bullet-like hole clearly visible on the site, on display in the National History Museum in London.
All these pieces of the puzzle have really brought us no closer to learning the truth. Numerous hypotheses and speculations have surfaced, from radical theories, such as the idea proposed by The Shields Gazette that “someone from the future, carrying a firearm, travelled back into the past and engaged in some sort of trans-temporal hunting expedition,” to the slightly more plausible suggestion that the holes were caused by shrapnel from a small meteorite or something similar.
In alternative archaeology circles, the most popular perspective is that ancient man may have been technologically developed to a very high degree, before virtually all traces were lost. But could two separate societies, separated by thousands of years and a vast cultural gulf, have both invented weapons that just happened to fire small, cylindrical projectiles at high speed?
The only lukewarm attempt to debunk the alternative theories comes from the Bad Archaeology website, which denies the injuries to the right-side of the skull exist. Although they present no explanation or evidence, they claim that the bullet-like hole was caused by “a pathological, rather than a traumatic lesion, caused by an infection in the soft tissue over it.”
At this stage, none of the hypotheses are supported by adequate evidence or logic. Unless more prehistoric skulls or fossils are discovered with the same type of injuries, we may never hold the real answers to the Kabwe skull enigma.

Lopen met vleugels van 6 meter lang valt echt niet mee…
Als je vandaag de dag door moerassig gebied loopt, zie je hooguit één meter lange reigers in ondiep water waden, op zoek naar visjes, insecten of schaaldieren. Maar zo’n 70 miljoen jaar geleden zou je langs de Texaanse Rio Grande-rivier een indrukwekkender en enger wezen door de moerassen hebben zien struinen. Het gaat om een vrij angstaanjagende pterosauriër, bekend als Quetzalcoatlus. Dit beest, met een spanwijdte van bijna 12 meter, was het grootste vliegende dier dat ooit op aarde leefde. En in een nieuwe studie schetsen onderzoekers nu het meest complete beeld van dit gevreesde familielid van de dinosaurus.
Mysterie In de jaren zeventig van de vorige eeuw ontdekte wetenschappers in het Amerikaanse Big Bend National Park de gefossiliseerde botten van de pterosauriër. Eén van de mysteries is echter sindsdien geweest hoe een dier met zes meter lange vleugels rond kon lopen… De vleugels zouden zelfs opgevouwen de grond moeten hebben geraakt. Bovendien gingen er onder zijn enorme vleugels in verhouding vrij kleine beentjes schuil. En dus is het de vraag hoe Quetzalcoatlus het luchtruim koos. “Dit oude vliegende reptiel is legendarisch,” zegt onderzoeker Kevin Padian. “Maar dit is de eerste keer dat we een grondige blik werpen op het grootste dier dat ooit op aarde rondvloog.”
Studie De onderzoekers bogen zich over de gefossiliseerde botten en vergeleken deze met talrijkere exemplaren van een kleinere Quetzalcoatlus-soort om het vlieg-, loop- en lanceergedrag beter te begrijpen. En uiteindelijk slaagde het onderzoeksteam erin het unieke loopje van Quetzalcoatlus te onthullen.
Vleugels Het beeld dat het onderzoeksteam uiteindelijk schetst, is van een dier dat best wat weg heeft van hedendaagse reigers, gecombineerd met kenmerken van condors en gieren. “Pterosauriërs hebben enorme borstbeenderen – de plek waar de vliegspieren zich hechten – dus het lijdt geen twijfel dat het geweldige vliegers waren,” zegt Padian. “Hun opperarmbeen – de humerus – kenmerkt zich door enorme, benige toppen waar de spieren die ze gebruikten om te vliegen, worden verankerd. Deze zijn groter dan die van vogels en veel groter dan die van vleermuizen. De vleugels werkten in wezen hetzelfde als die van vogels en andere dinosauriërs, waaraan pterosauriërs het nauwst verwant zijn.”
Meer over Quetzalcoatlus De onderzoekers vermoeden dat Quetzalcoatlus geen veren had: zijn lichaam – inclusief vleugels – was bedekt met haar, zoals bij alle pterosauriërs. Net als dinosaurussen waren ze warmbloedig en actief. Quetzalcoatlus had geen staart, vermoedelijk om zo wendbaarder te zijn. Daarnaast leek hij een beetje op een uit de kluiten gewassen ooievaar. De pterosauriër hield er waarschijnlijk een gevarieerd dieet op na en zocht in de modder naar krabbetjes, wormen en kokkels, maar ook kleine visjes, insecten, slangen en hagedissen stonden geregeld op zijn menu.
Net als vogels, vleermuizen en zelfs mensen, hebben de voorpoten van pterosauriërs drie segmenten: de humerus, de onderarm en de pols- en handbotjes. Maar in tegenstelling tot vogels en vleermuizen, bestaat het buitenste deel van de pterosauriërvleugel uit een gigantische ‘vleugelvinger’. “Het is vergelijkbaar met een skistok die zich vanaf het begin van je vingers uitstrekt en 90 graden naar buiten buigt,” legt Padian uit.
Tweevoetig Quetzalcoatlus was tweevoetig, wat betekent dat hij op twee benen liep. Maar omdat de botten van de voorpoten zo langwerpig zijn, raakten zijn vleugels de grond wanneer ze opgevouwen waren. Dit deed sommigen vermoeden dat de pterosauriërs zich net als een vampiervleermuis voortbewogen; die gebruiken hun voorpoten om zichzelf op de grond voort te stuwen.

De onderzoekers komen nu echter tot de ontdekking dat Quetzalcoatlus hier waarschijnlijk niet toe in staat was: als hij op de grond stond, kon hij zijn vleugels alleen naar voren of opzij bewegen. “Eenmaal op de grond, kon hij zijn voorpoten niet terugdraaien om vooruit te komen,” zegt Padian. “Het bot in zijn schouder zat daarvoor in de weg.” Om toch op de grond vooruit te komen, hief de pterosauriër eerst zijn linkerarm op, zette vervolgens met zijn linkerbeen een stap en plaatste zijn linkerarm op de grond. Dit proces herhaalde hij aan de rechterkant. “Dit lijkt misschien wat omslachtig,” zegt Padian. “Maar het dier kon de gang snel en gemakkelijk uitvoeren.”
Opstijgen Hoe Quetzalcoatlus opsteeg? Omdat zijn poten korter waren dan zijn vleugels, kon hij niet simpelweg met zijn vleugels klapperen om zichzelf te lanceren. De onderzoekers vermoeden dan ook dat de pterosauriër zijn sterke achterpoten gebruikte om omhoog te springen. Vervolgens begon hij, zodra er enige ruimte onder hem was gekomen, met zijn vleugels te klapperen. Reigers en zilverreigers doen hetzelfde, hoewel ze aanzienlijk kleiner zijn dan Quetzalcoatlus.

De bevindingen zijn revolutionair voor de studie naar pterosauriërs – de eerste dieren, na insecten, die ooit een gemotoriseerde vlucht ontwikkelden. Padian geeft toe dat er nog steeds enkele vragen over Quetzalcoatlus en pterosauriërs in het algemeen onbeantwoord blijven. Maar dankzij het omvangrijke onderzoek hebben we nu wel een veel beter beeld van hoe het grootste vliegende dier dat ooit op aarde leefde, zich – op vrij eigenaardige wijze – voortbewoog.
