What is the word on Phil Currie's Tyrannosaur study? I hear he
might be making a case for putting Daspleteosaurus in whith Albertosaurus.
I'd also like to hear opinions on taxonomic assignments based on
teeth. This is apparently unadvisible with most types of dinosaurs, but
I understand that theropod teeth are quite diagnostic, which is why Phil
Currie and Ken Carpenter advocate the ligitamacy of Aublysodon, and place
the Jordan Theropod ("Stigyvenator") within this genus.
I saw the cast of the new Acrocanthosaurus skull that Ken and Phil
Currie will be describing. It is unbeleivably huge, just a hair below
the size of the AMNH 5027 (Tyrannosaurus rex) skull. When I first saw it
I thought for sure that it was an oddly distorted T.rex skull. The
"orbital knob" also looks like the above mentioned T.rex's, very rugose
and shaped the same (sort of a ball shaped knob with a hemispherical
ridge shadowing the orbit).
