I don`t like the fact that it splits prolacertiforms off from the
archosauriformes. Prolacertiforms is perhaps a bad term. Some say it is
questionable that they led to modern day squamata. I`m not sure,...(maybe
they actually did), but I also think they led to the archosaurs as well.
Mainly because many of them possess an antorbital fenestra, a key feature of
true archosaurs, and they appear at an early enough time to be ancestral.
