Why Most People Still Draw T. Rex Wrong After 25 Years of Research

In 2011, a paleontology professor at Cornell University named Warren Allmon asked a college newspaper reporter to do something simple: draw a Tyrannosaurus rex. The reporter, who had grown up obsessed with dinosaurs, was confident. Shelves of figurines, sketchbooks full of doodles—surely this would be easy. The drawing came back with the dinosaur standing nearly upright, spine vertical, tail dragging. Allmon's response was gentle but firm: scientists had stopped thinking T. rex stood that way in the 1970s. The posture was wrong.

It turned out the reporter was not alone in this mistake. Allmon and his colleague Robert Ross, both paleontologists at the Paleontological Research Institution in Ithaca, New York, had been collecting student drawings of T. rex for years. When they published their findings in 2013, the numbers were striking: 72 percent of college students and 63 percent of precollege students drew the dinosaur standing upright rather than in the correct horizontal posture that modern science now understands. The disconnect was stark. When paleontologists first mounted a T. rex skeleton for public display in 1905, they positioned it with a spinal angle of roughly 57 degrees to the horizontal—an upright stance that looked regal and imposing. Today, scientists display the skeleton with a spinal angle of zero to ten degrees, nearly parallel to the ground. A century of research had fundamentally changed how we understand the animal's body mechanics, yet the old image persisted in the public mind.

Allmon blamed what he called "dino crap"—the accumulated cultural detritus of childhood dinosaur encounters. Barney & Friends, cheap plastic toys, dinosaur chicken nuggets shaped like the creatures. These images, absorbed before age seven, calcified into permanent mental pictures. "For most people, all of our dinosaur knowledge goes to hell once we turn about seven," Allmon said. The childhood obsession rarely survived into adulthood, and neither did the capacity to update it.

Fifteen years after that initial embarrassing drawing, the reporter reconnected with Ross to see if anything had changed. It had not. Ross had continued the experiment for a quarter century, accumulating more than 5,000 drawings from students at Cornell and nearby Ithaca College. When Ross pulled up images from his most recent class, the errors persisted. One drawing showed a T. rex with four legs. Another had the correct two-legged stance but stood upright with spikes running down its back like Godzilla and too many fingers on its hands. Some were accurate, but they remained the minority. The old mistakes lived on.

The problem extended far beyond posture. Kiersten Formoso, a vertebrate paleontologist at Rutgers University, pointed out that many dinosaurs were feathered—a fact that contradicts decades of popular imagery. Velociraptor, famous from Jurassic Park as a scaly, man-sized predator, was actually covered in plumage and no larger than a turkey. Jingmai O'Connor, a paleontologist at the Field Museum in Chicago, noted that most people still did not grasp that birds are dinosaurs. Riley Black, a National Geographic contributor, added that birds are so ancient they lived alongside non-avian dinosaurs for roughly a hundred million years, with Archaeopteryx dating back 150 million years to the time of Stegosaurus and Allosaurus.

Other misconceptions ran deeper still. Stegosaurus and T. rex are routinely depicted together in popular culture, yet they were separated by more than 80 million years—a span of time greater than the distance between T. rex and the present day. Holly Woodward Ballard, a paleontologist at Oklahoma State University, emphasized that the definition of what counts as a dinosaur remains widely misunderstood. Dimetrodon, pterosaurs, mosasaurs, and plesiosaurs are frequently lumped together with dinosaurs by the public, yet none of them belong to that group. The category itself had become a catch-all for anything prehistoric and reptilian.

Ross and Allmon wanted to correct one final misconception: that "dinosaur" is a derogatory term meaning outdated or unable to adapt. The fossil record tells a different story. Dinosaurs were among the most spectacularly successful animals ever to live, thriving for roughly 165 million years until the extinction event that ended their reign. To be compared to a dinosaur, Ross suggested, should be a compliment.

When the reporter tested colleagues at National Geographic and family members over a holiday weekend with the same drawing challenge, the results mirrored the data. Most drew upright dinosaurs resembling inflatable Halloween costumes. At least two had four legs. The gap between what paleontologists know and what the public imagines remains as wide as it was a quarter century ago, stubbornly resistant to the accumulation of scientific evidence.
