Not carnosaurs, this time...



For those of you who can't stand cladograms, guess what?  I just finished
running a dataset on tyrannosaurs, and here's a sneak preview.  At some
point I plan to post this on the web, with character states etc (my web
page is in danger right now, and so are these computers, which have crashed
or had the power go out twice today).

This is from a dataset of 29 discrete characters in eleven taxa with two
outgroups.
