Here is news of a really beautiful fossil found recently:

Brazilian paleontologists have found the near complete fossil of a fearsome predator that roamed the Earth before the dinosaurs.
The 22ft long creature, called Prestosuchus chiniquensis, lived some 238million years ago. It belonged to a family of reptiles called thecodonts and had a large, deep skull with serrated teeth and a long tail.

This is how it may have looked in life:

Weighing 900lbs, the carnivores romated Earth during the Triassic Period 250 to 205 million years ago. Dinosaurs came to dominate from 230million years ago up to their extinction 65million years ago.
The well-preserved creature was found by a team from the Lutheran University of Brazil, in the town of Dona Francisca 160miles from Porto Alegre.

I haven't quoted the article in full.

Sweet pics.

Amazing it was so well preserved.

Looks almost like dimetrodon without a sail.

Love how they almost always look to have a cheeky grin in the artists renditions.

They are incredibly primal looking beasts. Here's to finding more.

On the dimetrodon angle, do we know if it was a synapsid?

Cheers, that is somewhat helpful.

It seems it is a diapsid, making a completely different family to Dimetrodon.

Diapsids evolved into the modern reptiles, such as crocodiles lizards and snakes. Even birds fit into this family tree. Dinosaurs also were Diapsids.

Synapsids on the other hand evolved into the mammal like reptiles and the mammals.

Sorry, bit of a nerd for this crap. Love the thread mate, get any more of it you know where to stick it.

Here's a thread I made a little while ago about the discovery of an Abydosaurus:

If you do a search you'll probably find quite a few threads on ATS about dinosaurs and their ilk, and probably authored by people far more knowledgeable than me
