Re: new paper

So does anyone know what species of diapsids were used in this phylogenetic inference?

What is the DML opinion on this paper?  Were _Deinonychus antirrhopus_

This just in:

B.T. Roach and D.L. Brinkman.  2007.  A reevaluation of cooperative pack
and gregariousness in Deinonychus antirrhopus and other nonavian theropod
dinosaurs.  Bulletin of the Peabody Museum of Natural History 48: 103-138.

Brinkman was an undergrad student of mine in the day; he worked with me on
tyrannosaurid teeth.

This is an interesting critical take on theropod sociality that is bound
to be
controversial.  It also describes an impressive bit of taphonomic CSI
about dromaeosaurid personality.  I won't give the story away any more
that, and simply quote the esteemed Brother Holtz:  Read the paper.
