Re: Amniota to Mammalia in four easy steps

I'm not sure how correct Anomodontia is for whatever the group is that
includes Dicynodontia (which in any case includes *Placerias*), given the
recent confusion about that part of the tree. The "cynodont" of WWD may have
intended to be *Thrinaxodon*, I guess (an anachronism, but *Cynognathus*
would have been one, too); would occupy the same position in this cladogram
in any case.
        *Procynosuchus*, that basal cynodont that tried to be a croc, might
be an interesting addition... but additions are not what you want, I think
:-)
