The Thing With Feathers

T. rex is the thing with feathers
That stands 20 feet tall
And eats 500 pounds of meat per bite
And never stops at all

(Sadly, Tyrannosaurus rex and the larger theropods probably lost most of their plumage over the course of their evolution. Skin prints show no indication of feathers.)

T. rex were much bigger than their predecessors, having developed long legs that let them dash after prey. But large and active animals don’t cool down as quickly as smaller creatures. So as they got bigger, researchers think that the dinosaurs may have lost their plumage. “[F]eathers were too much of a hindrance to cooling off after a sprint,” Bittel writes.
