Subject: Croc-like fossil reveals earliest dinosaur ancestor

Around 250 million years ago, a large group of ancient reptiles named archosaurs diverged into two distinct lineages. One branch evolved into dinosaurs and birds and the other branch gave us the crocodiles and alligators we know today, plus a host of now-extinct relatives. A new fossil discovery, named Teleocrater rhadinus, is a species from the dinosaur/bird lineage that marks the oldest known cousin to the dinosaur and fills a large gap in our fossil history.

yep. very interesting.

One of the Good Scientist cartoons features a critter just like this, an archosaur just on the bird/dinosaur side of the split with the crocodiles.

From OP link on teleocrater. Notice that it’s a quadruped that also had the ability to run on two legs.

Similar creature from Good Scientist cartoon.

Wikipedia entry on silesaurus. It’s almost identical to teleocrater.

No, the silesaurus was not a true quadruped and was from a later period than teleocrater, which was a true quadruped and due to its leg structure was unable to run on two legs.

You’re smart. Yes that’s absolutely correct. I was trying to pull the wool over your eyes. Well spotted.

Subject line is a bit misleading

Very interesting thought. How do you reach that opinion?
