Horns, spikes and bony plates—dinosaurs developed many diversifications to guard themselves. However paleontologist Lawrence M. Witmer has found {that a} group of dinosaurs referred to as ankylosaurs had a secret weapon. It was much more necessary than their tanklike armor, and it was hidden inside their cranium: their nasal passages.

Ankylosaurs’ thick full-body armor protected them from predators, nevertheless it didn’t enable a lot warmth to flee from their big physique. Paleontologists had been puzzled at how these animals had been in a position to regulate their temperature and survive below the blazing Cretaceous-period solar.

Utilizing superior scanning and 3-D modeling applied sciences in his Ohio College lab, Witmer and his colleagues found that Euoplocephalus, a genus of ankylosaurs, had unusual corkscrew-shaped nasal passages that Witmer likens to a “kid’s loopy straw.”

Jason Bourke, a former doctoral scholar of Witmer’s, now on the New York Institute of Know-how School of Osteopathic Medication at Arkansas State, modeled the dinosaur’s nasal airflow and located the corkscrew form allowed the passages to behave just like the coils inside a contemporary air conditioner. They helped cool ankylosaurs’ blood earlier than it reached the mind, stopping the animals from dying of warmth stroke.

Witmer’s research is a component of a bigger analysis effort to know how completely different teams of dinosaurs handled the intense warmth of their setting. In in ankylosaur fossils, the reply was comparatively straightforward to seek out: their nasal passages had been well-preserved inside their bony cranium. However the reply is proving extra elusive in dinosaurs whose cranium had massive openings, together with long-necked sauropods and carnivorous dinosaurs akin to Tyrannosaurus rex.

For Witmer, unearthing this information shouldn’t be strictly about understanding the giants of the previous. “Proper now we’re seeing this unprecedented world warming, world local weather change, which is disrupting every kind of climate patterns,” he says. “Dinosaurs, in a way, can provide us some perception into how animals at the moment would possibly have the ability to cope with this elevated warmth that we see.”
