[RikaStrom]

a two-legged carnivore that could not fly and belongs to the same family as the larger and more fearsome Tyrannosaurus rex.

An ancient ostrich?

Somehow I just can't picture a relative to T-Rex sticking his head in a hole! Into an herbivore yes, but not the ground. ;-)

Change it to verbivore and hobbes, dubya and I could have field day with this one.
