They did not act like mammals or birds, nor did they act like reptiles or fish," said University of Arizona evolutionary biologist and ecologist Brian Enquist.

There has been much debate about the supposedly useless arms of Tyrannosaurus rex. "The earliest tyrannosaur species had arms that were perfectly proportioned," Erickson said. The close relationship between theropods and birds has been hinted at since Richard Owen first noticed the honeycombing in three Megalosaurus vertebrae in 1856. Stevens built a scale model of the T. rexs head and popped in some taxidermic eyes based on the eyes of three animals pretty closely related to T. rexalligators, ostriches, and eaglesand adapted for situations that a dinosaur would have likely encountered.

Although not as intelligent as most modern birds, or animals. They were one of several different mammal lineages that emerged around that time. Scientists who do not agree say that not enough specimens have been collected to truly recognize robust and gracile morphotypes or any significant differences in the skeletons, and we probably never will know the answer. "Instead, they had growth rates and metabolisms intermediate to warm-blooded and cold-blooded organisms of today.
