... and a transitional fossil to boot!
One of the constant complaints of IDers and creationists is that there aren't any transitional fossils. This, of course, misses the point that all fossils are transitional fossils. But here is evidence (not the drawing, but the linked article with video) of an early cousin of the awesome Tyrannosaurus rex.
This is a conception of the Raptorex.
Despite what many newspapers will assuredly tell you, Raptorex isn't the ancestor of Tyrannosaurus although it probably looked very much like what this hypothetical animal would have done. It's more like an early cousin, but one that's clearly more closely related to T.rex and its giant kin than any of the other smaller species so far discovered.
You can read all about it over at the marvelous Not Exactly Rocket Science blog. And watch carefully for the depiction of the teeny-tiny brain these creatures had (but apparently a very good sense of smell.)
