Re: You Can't Nitpick a Carnosaur

  This was pointed out to me privately, and I realized I made a
serious error ... Never has spinosaurs and torvosaurids been
placed nearer birds than allosaurids were, and in fact I
misplaced them by a few nodes.... They are closer to birds than
*Megalosaurus,* by every phylogeny published with them both in
it that I've ever seen (I don't have Thulborn's phylogeny, can
only comment on what Mickey Mortimer has posted on this). They
are non-avetheropod tetanurines, and in fact the clade
{*Torvosaurus* + birds} is called Neotetanurae, to the exclusion
of *Megalosaurus* [basal-most Tetanurae]. So appologies to Holtz
and Sereno et al. and their published phylogenies....
