Re: Yonghesuchus, was Shuvosaurus



Quoting david peters <davidrpeters@earthlink.net>:

DM: Are you sure you've included all proposed
apomorphies of Archosauriformes as characters in your analysis?

Not necessary, as explained way earlier.

Not necessary??? You're claiming to have dismantled Archosauriformes, Archosauria, and Crurotarsi (by pulling Parasuchia outside all of these), and yet you haven't included all the characters supporting those clades? I hope you can see how this is not a valid test.

Taxon inclusion is all that is necessary after 150 or so characters are used.

No, as David mentioned, adding taxa while holding character number constant will
only *decrease* resolution.
