Re: Gaia theropod follow-up: a "new" phylogeny

["ekaterina amalitzkaya" <eamalitz@hotmail.com>]

In the phylogenetic tree provided by Thomas R. Holtz Jr. there was no 
Cryolophosaurus. Was this just an accidental ommision or was it left out due 
to specific reasons? The early tetanurans according to this picture do not 
form any good cluster but simply stack up on the crown group. Does this 
suggest a general lack of specialized innovation in the early Gondwanaland? 
How much of this M.bucklandi is known. I remember a dentary that was well 
illustrated in a pamphlet provided by some English museum. Is there more to 
this beast. The same pamphlet also showed a small theropod called Altispinax 
and called these large neural spines as coming from some Megalosaurus 
species. Any idea what these neural spines came from?

Thanks
