Re: STRANGE THEROPOD SKULLS

<<< |..Altispinax >>>

<This genus is based on a single tooth, the type specimen of 
_Megalosaurus dunkeri_, which might be lost (a correspondent tried to 
locate it at Marburg, Germany but couldn't). I doubt you could classify 
it as anything more definite than Theropoda _incertae sedis_ or 
Carnosauria _incertae sedis_. It's not tyrannosaurid, at any rate.>

I place it there because *Altispinax*, *Valdoraptor*, and *Becklespinax* 
may all be the same dino; Beckles is very eustreptospondylid-like, and 
*Valdoraptor* is like both *Eustreptospondylus* and *Allosaurus* in the 
morphology of the metatarsals. I believe this is indicative enough to 
place them all there, but a conservative _incertae sedis_ label should 
be applied for Alti, and I will take this advice.
