An anonymous reader writes In a new study, paleontologists revealed that armor–plated Ankylosaurs had an exceptional capability to change the temperature of the air they breathed with the help of their long, winding nasal passages. From the article: "Led by paleontologist Jason Bourke, a team of scientists at Ohio University used CT scans to document the anatomy of nasal passages in two different ankylosaur species. The team then modeled airflow through 3D reconstructions of these tubes. Bourke found that the convoluted passageways would have given the inhaled air more time and more surface area to warm up to body temperature by drawing heat away from nearby blood vessels. As a result, the blood would be cooled, and shunted to the brain to keep its temperature stable."
