Re: Asilisaurus kongwe



If the Silesauridae is the sister group of the Dinosauria, then its
presence in the Anisian indicates an older age for the Dinosauria (I
mean, as old as the Silesauridae). Also, for pterosaurs, and the
stem-taxa leading to Scleromochlus, Lagerpeton and Marasuchus but not
dinosaurs.

Regarding the "bird-line", I think this corresponds to the
Avemetatarsalia (erected by Benton, 1999, in the Scleromochlus paper
in Philosophical Transactions). Avemetatarsalia are all those living
beings more closely related to birds than to crocodiles.
