The Cretaceous period's carnivorous answer to a camel has been unearthed in Europe after 130 million years, a new study say.
The new, hunchbacked species of dinosaur sprouted spiky, featherlike shafts on its arms; was probably a powerful runner; and likely ate small dinosaurs, crocodiles, and early mammals, researchers say.
Discovered via a finely preserved, nearly complete skeleton found in central Spain, the 20-foot-long (6-meter-long) Concavenator corcovatus—"the hunchback hunter from Cuenca"—had two raised backbones, each 1.3 feet (40 centimeters) taller than the dinosaurs' other vertebrae.
C. corcovatus's hump possibly supported a mound of fleshy tissue storing fat, as on a camel, according to the study team, led by paleontologist Francisco Ortega of the Universidad Nacional de Educacíon a Distancia in Madrid.
Alternatively, the hump might have had a display role—for example, attracting a mate or intimidating rivals—or may have helped diffuse heat and regulate body temperature, Ortega said.
I refuse to call it a camelsaur.
So, being a carcharodontosaurid spread to likely point that quills if not feathers evolved, right?
