RE:Elaphrosaurus and Abelisaur taxonomy
Tom HolTz: Go ahead, be snotty, just keep publishing :)
Elaphrosaurus: Ok, boss, but are you SURE it's not
tetanuran?
Poikilopleuron and Megalosaurus synonymized?
Megalosaurus has a humerus bent at a 30-degree angle, P.
bucklandi's is straight (and, admittedly, more like
Torvosaurus' than Megalosaurus')! I realize that modern genera
show a high degree of morphological difference, but to that
degree?
Torvosaurus: Yes it's claws may be massive, but what
good could they be in a running (or running/jumping) attack?
Does anyone have any ideas about how it would use them arms?
Abelisaurid orbits: Senor HolTz, I think you missed my
point, which was, admittedly, a weak one. The Abelisaurid
Orbital bar continues the margin of the upper orbit in a
smooth circle, curving upwards. Tyrannosaur and Acrocanthosaur
orbital bars don't seem to do this (except for, if memory
serves, an Albertosaur (A. sarcophagus?) figured by Paul in
_PDW_), but instead they bulge out in a lump from the
postorbital bar.
I still cannot recall which, but either
Eustreptospondylus or Piatznykisaurus appears to be VERY similar to
to other alleged "megalosaurs".
So, anyway, Holtz or anyone else, any discussion of
Ceratosaurus et al. being pehaps not being closer to
Coelyphsids than to the Tetanurae?
