Bird origin ref.
Just got hold of a reprint of this ref. Welman, J. 1995. Euparkeria and
the origin of birds. South African Journal of Science 91, 533-537.
In this paper Welman compares the braincases of Euparkeria, Euskelosaurus
Syntarsus and Sphenosuchus with those of birds. He found that
the dinosaurs and sphenosuchus share derived characters not seen in
either birds or Euparkeria and that there were some derived characters
shared between Euparkeria and birds. He concluded that there was a sister
group relationship between Euparkeria and Birds! Obviously the principle
of total evidence was ignored.
