What's the Difference?- The T. rex Name Game

Readers, for once, I'm at a loss, surprising as it seems. The different media that encompasses prehistoric organisms, especially theropod dinosaurs, have a way of calling two similar but different species of the same genus, the same animal. In fact, they've done this with Tyrannosaurus rex as shown here:

And here...

They look different, don't they? The only reason I have for that is either their two different species of the genus Tyrannosaurus or their the same genus and species but are different subspieces, kind of like the difference between Humans: Neanderthals and Cro-magnons. They're both human but, their different kinds of the same human. In this case, Biologists, Anthropologists, and Paleoanthropologists give them the scientific names: Homo sapiens neanderthalensis (Neanderthals) and Homo sapiens sapiens (Cro-magnons, us?). Let me tell you first hand that I'm NOT an Anthropologist. So, if I made a mistake, bare with me. I consider myself an Amateur Paleonotlogist. Anyway, the point is, that's the only reason I can think of for the difference.

You are right. There are some slight differences. Of course the one is an illustration, so it's probably not as accurate as a photo, which would explain the differences. Although it could be a subspecies like you said.

No, because I've seen a skull that looks like the second one, cast and fossil. Both were labeled Tyrannosaurus rex.

Yeah, my best guess would be subspecies. However, I e-mailed the pictures to paleontologist Dr. Thomas R. Holtz, jr of the University of Maryland about it today. Hopefully he would know.

Who knows with T. rex. . .the stratigraphic control on most of the specimens is simply awful! We have little or no idea if the differences are temporal, regional, or who knows what. . .frustrating.

It's amazing how the skull of a T-Rex became famous in the minds and mouths of humanity, what I'm concern is whether scientists are wrong with some theories, I was reading a book regarding dinosaurs and suddenly a tablet of Viagra Online appeared inside the book.
