Mini-T. rex would probably still bite your head off!Posted: September 21, 2009
A fossil has been found in northern China that appears to be an ancestor of Tyrannosaurus rex.
Dubbed Raptorex, it lived about 125 million years ago and bears the same characteristic features of its renowned descendent. Described as ‘a jaw on legs’ this body shape came to dominate the later carnosaur appearance. It is important because it demonstrates that these animals and their descendants were incredibly well-adapted. Having found this fossil has also gone some way towards explaining the tiny forelimbs that the giant T. rex bears: perhaps they remained undeveloped, un-needed once the animal had successfully occupied and dominated its ecological niche.
