The first Tyrannosaurus rex I ever met was horribly out of
date. Propped upright in the Cretaceous dinosaur hall at the American
Museum of Natural History, the snarling tyrant held the same
tail-dragging pose that it had for the past eight decades, seemingly in defiance of paleontologists who were promoting an updated rendition of T. rex as a speedy killer with a more horizontally-oriented spine. The dinosaur’s new persona was struggling to subdue the old.
By 1994, the AMNH renovated their dinosaur halls and gave their T. rex a proper spinal adjustment. And the spectacular cinema dinosaurs of Jurassic Park instantly popularized the adjusted posture and supercharged nature of the tyrant. T. rex
was not a tottering Godzilla wannabe. Yet, twenty years after Stan
Winston’s dinosaurs tore up the screen and over four decades since the
“Dinosaur Renaissance” sparked a major revision of the way we understand
dinosaurs, the specter of the unbalanced T. rex still clings to our imagination.
Ask an elementary school student to draw a T. rex, and they
will probably depict the tyrant with a sloping back and drooping tail.
College students are even more likely to make the same error. That’s
what paleontologists Robert Ross, Don Duggan-Haas, and Warren Allmon
found when they asked students to do just that in an effort to see how
public perception of dinosaurs matches up with scientific understanding.
Despite museum displays, carefully illustrated works of paleo art, and
even blockbuster films, young students from elementary school to
university envision the classic dinosaur in a pose that is strikingly
similar to the reconstruction paleontologist William Diller Matthew drew
over a century ago.
In the first illustration of a T. rex skeleton, published
with the theropod’s initial description, the dinosaur’s spine sloped at
an angle of 57°. Modern illustrations tend to depict the dinosaur with
vertebral column held between 0 and 10° in respect to a flat surface.
Most of the drawings by the sampled students didn’t even come close to
the current representations. Within a sample of 111 Ithaca College
undergraduates and 205 elementary to middle school students who visited
the Paleontological Research Institution in Ithaca, New York, students
most often drew T. rex with a spinal angle of over 40°, with
the college students being more likely to draw the dinosaur with the
incorrect posture than precollege students. In the minds of some
students, at least, T. rex is lagging a century behind the science.
Why should such a discrepancy exist? With the exception of a very few – such as the high-kicking T. rex at the Denver Museum of Nature and Science
– reconstructions of the famous tyrant dinosaur in most of America’s
major museums have been adjusted into more accurate poses, and modern T. rex
have been stomping around movies and television documentaries for
decades. Obviously the illustrations of precollege students involve a
fair bit of imagination and artistic license – accuracy was not
necessarily at the forefront of my mind when I scribbled dinosaurs in
elementary art class – but why would university students taking a
geology class be so far off the mark?
Ross and co-authors suspect that pop culture is the culprit. Despite
scientific advances and some real outreach successes in updating the
public image of dinosaurs, there’s a ton of dinosaur kitsch and crap out
there that still presents T. rex circa 1905. Everything from cookie-cutters and cartoons to dinosaur-shaped chicken tenders and plush toys show T. rex in the wrong posture. Even “Buddy” from the popular kid’s show Dinosaur Train perpetuates the old T. rex imagery! Amazing, scientifically-accurate reconstructions and restorations of T. rex are totally swamped by oldschool images that establish the outline of what a dinosaur is from the time kids are first introduced to the prehistoric celebrities.
If you haven’t asked this already, by now you’re probably wondering
why tyrannosaur posture matters. It seems a rather frivolous bit of
dinosaurian arcana to get frustrated about. But even though this
specific example might seem inconsequential, the trend Ross and
colleagues found among the sampled students pinpoints a significant
problem with the “deficit model” of science communication.
Comfortable assumptions to the contrary, the public is not some
amorphous and empty vessel that will readily accept scientific knowledge
as soon as they hear an expert speak. Some of the most pressing issues
in science communication today are not going to be solved by more
scientists simply speaking at greater length at at higher volume. The
perpetually-broken back of T. rex in amateur art underscores the complexity of getting good science out to the public.
Not only have paleontologists and paleoartists been able to present up-to-date visions of T. rex
in museum exhibits attended by millions each year, dinosaur experts
have had great success at presenting their science through documentaries
and even Hollywood films. Despite all this, though, everything from the
toys museums sell to internet memes perpetuate discarded science. Getting people to understand something as simple as the way T. rex
stood isn’t merely a matter of a paleontologist saying “This is the way
the dinosaur looked” and the public responding “Huh. Ok. Thanks!”
Scientific facts and imagery are intertwined with, and often compete
with, pop culture tidbits that can distort even the simplest of
findings. To replace those misunderstandings with what we know and how
we know it, we must first identify how those misconceptions evolve. I
doubt that awkward, wobbly T. rex are going to disappear
anytime soon, but perhaps researchers can use these ungainly and
incorrect dinosaurs as a springboard to explain how much more amazing
the real king of the tyrant dinosaurs was.
