Re: Gondwana Split Sorts Out Mammalian Evolution

[João Simões Lopes Filho <jodan99@uol.com.br>]

In fact Creodonta were found in African Paleocene. Perhaps they were the
carnivore Afrotherians, flaying the role of Laurasian Carnivora and South
American Borhyaenoids.

And South American Alcidedorbignya...is it still considered as a Pantodont?
Can be Pantodonts closer to Xenarthra? Can Carodnia (Xenungulata) be
relative of Dinocerata ?
