Newswise–Tyrannosaurus rex, one of the largest meat-eating dinosaurs on the planet, had an air conditioner in its head, suggest scientists from the University of Missouri, Ohio University and University of Florida, while challenging over a century of previous beliefs. In the past, scientists believed two large holes in the roof of a T. rex‘s skull — […]
Running May Have Made Dinosaurs’ Wings Flap Before They Evolved To Fly
(Newswise)–Before they evolved the ability to fly, two-legged dinosaurs may have begun to flap their wings as a passive effect of running along the ground, according to new research by Jing-Shan Zhao of Tsinghua University, Beijing, and his colleagues. The findings, published in PLOS Computational Biology, provide new insights into the origin of avian flight, which […]
Ankylosaurs Likely Regulated Body Temperature With Elaborate Nasal Passages
(Newswise)–Ankylosaurs likely regulated their body temperature with convoluted nasal passages that acted as heat exchangers between air and body, according to a study published December 19 in the open-access journal PLOS ONE by Jason Bourke from Ohio University, USA, and colleagues. Modern mammals and birds have long, convoluted nasal passages called turbinates that function as […]
