So why are students’ perceptions of the T. rex stalled in the early 1900s, when the dinosaurs were depicted as upright, somewhat slow-moving tail draggers? A Cornell University research team sought answers after years of anecdotally observing students drawing the T. rex incorrectly.

For Some Feathered Dinosaurs, Bigger Not Always Better

Giant Pterosaur Needed Cliffs, Downward-Sloping Runways to Taxi, Awkwardly Take Off into Air

Dinosaur Era Acoustics: Global Warming May Give Oceans the ‘Sound’ of the Cretaceous

Global temperatures directly affect the acidity of the ocean, which in turn changes the acoustical properties of sea water. New research suggests that global warming may give Earth’s oceans the same hi-fi sound qualities they had more than 100 million years ago, during the Age of the Dinosaurs.

Researchers Find Genetic Evidence That Turtles Are More Closely Related To Birds Than Lizards And Snakes

Having recently looked at more than a thousand of the least-changed regions in the genomes of turtles and their closest relatives, a team of Boston University researchers has confirmed that turtles are most closely related to crocodilians and birds rather than to lizards, snakes, and tuataras.
