Well, it looks like the prestigious Chicago Field Musuem, home to the drop-dead gorgeous lady Sue the T. rex, renowned paleontologist Paul C. Sereno (will he EVER stop discovering things? :-D), and a current exhibit on the father of modern genetics, Gregor Mendel, will have this specimen (I think it's a cast) of "Nanotyrannus."
So, basically, there has been a debate for a long time about this particular animal. Is it just a young Tyrannosaurus rex, or is it a whole new species or even genus, just a smaller kind? Juvenile, or new? That is the question!
So, I have wondered about this myself a bit. I thought that I was decided when I heard the results of the x-ray study on the skull (Robert Bakker was involved in this). Basically, young animals, including humans, have loosely attaches skull bones. In older individuals, they have grown closer together. This study's conclusion said that it was a new genus, Nanotyrannus.
But now, the guy in charge of this new exhibit, thinks it's a juvenile T. rex. Now I'm confused yet again!
Oh, so many questions, so few answers.
P.S. Oh, by the way, today Martin Luther nailed up his 95 Theses. That's what I'M celebrating, instead of Helloween!
