Re: Gliders to Fliers?

This is NOT to support George's arboreal theropod ideas, but where the
hell is the evidence that all of the early ceratosaurs were living in
hyper arid environments with no trees??????

Petrified Forest Member of the Chinle Formation?  There is evidence of
abundant and widespread plant life all over in these rocks. LARGE trees.

Red Beds DO NOT necessarily indicate hyper aridity and these theropods
are not being recovered from the aeolian deposits.  True, we do find
coelophysoidish teeth in cross-bedded aeolian sands in the Bay of Fundy,
but they were not exclusively there.

What is the Cactus park environ like, where Dilopho-sized tracks and smaller are found? I was under the impression that during the Trias and early Juras, with the landlocked continents of Pangea the inner portions of the continents became very arid and dry. Is there any evidence that the Petrified Forest was a large oasis of sorts? I've read some Frakes and Judy Parrish things on climate: any new interps of Trias climate: less dry, more wet, what?
