WASHINGTON (AP).- The weird world of dinosaurs has just gotten a tad more bizarre. Scientists found a nearly complete fossil of a new dinosaur that sports a noticeable hump, maybe as possible advertising. The hump on the dinosaur’s back, which was at least 16 inches tall, may have been used to help this meat-eating theropod communicate among its own species, scientists theorize. Discoverer Francisco Ortega of Spain named it Concavenator corcovatus which means “the hunchback hunter from Cuenca.” Ortega said the hump could have been used to store fat or regulate body temperature, but there is also the distinct possibility that it was used by concavenators to somehow differentiate themselves or communicate with each other. But with only one of these dinos, it’s only speculation and is hard to figure out what the humps were meant to convey if they were tools of communication, he said.
