So much for evolutionary scenarios and other just-so stories... actually
it's a pity :.-)

Hey! That's supposed to be strange there! :-)

You think (in your next post) that's a possible synapomorphy of Metornithes?
Despite *Patagonykus* with its vertical pubes?
What were the OTUs in Avialae? Only *Archaeopteryx*, as I fear?
