Dinosaur heads ‘like nothing scene in nature’

– How peculiar were the features of dinosaurs circling modern Brazil 110 million years ago? They “like nothing I’ve seen before in nature,” David Martill, the lead author of a study of the creature, tells Guardian. “There are a lot of other weird dinosaurs, but this is unlike any of them.” The beaked dinosaur was about the size of a chicken, with two legs and a long tail, sporting a mane of protofar, a form of early feathers, which could look like hair. “Stranger still” is the presence of two very long, perhaps rigid ribbons on either side of it, Martill states in a release. These protrusions — likely to be made of keratin, lend material similar to your fingernails — in the name of dinosaurs, Ubirajara jubatus. The first part comes from the Tupi name for “lord of the spear”, while the second refers to a Latin word for “science,” per science news.

Martill hopes that Dino had hair-sized protophers on much of his body … it has a long back and is given a kind of mane that is unique to dinosaurs. Dinosaurs probably could have increased the mane in the display. Shoulder stretches added to the show could include “elaborate dancing”, either to attract mates or to intimidate rivals, say researchers, who believe the sample analyzed was male. That specimen was brought to a Brazilian museum about 30 years ago; In 1995 Martill and a colleague requested that it be sent to Germany, from where it has been studied. “It represents a revolution in the communication of dinosaurs, the effects of which we can still see in living birds today,” such as peacocks and birds of paradise, says study co-author Robert Smith. Actually, “Ubirajara Shows us that this tendency to show is “inherited” from dinosaurs. (Read more dinosaur stories.)
