Well, it's 4 AM and I can't seem to find the answer. Do any of you know whether birds and pterosaurs shared a common ancestor, and what evidence we have to that effect?

It seems that birds and pterosaurs did not come from the same common ancestor.

That website lists that as a creationist claim, are you sure that's accurate?"I'm moving to the Left" - Lancer

You'd think that the dinosaurs would eat all the birds.“As a lifelong member of the Columbia Business School community, I adhere to the principles of truth, integrity, and respect. I will not lie, cheat, steal, or tolerate those who do.”

The webpage is a rebuttal of the creationist claim that there are no intermediate fossils between birds and dinosaurs, with some references at the bottom that you may find useful.Originally posted by Shi Huangdi

Embedded in the middle somewhere is the hypothesis that birds came from theropod dinosaurs.(\__/) 07/07/1937 - Never forget

Birds and Pterosaurs are not immediately related. Avians branched off from the Saurischian division of Archosauria (think T-Rex, Velociraptor, Brachiosaurus, etc.) while Pterosaurs are a division of Archosauria in their own right.
"Dinosaurs" refers to the Saurischian and Ornithischian (think Triceratops, Stegosaurus, Parasaurolophus, etc.) branches of Archosauria.

Check out this site with lots of info about the new feathered dino discoveries:
Luis Rey's Art Gallery
These paintings are awesome.
St. Leo, Saurischia and Ornithischia didn't have seperate archosaurian ancestors, that has been defunct for over 20 years.
These are the unique features of the Dinosauria (including Aves):
- A hole in the hip bones connect the hip sockets
- 3 or more vertabrae fused to the hip bones
- Erect, not sprawling, gait
- Ankle joints simple, foreward-backward hingesComment

However, "dinosaur" is also a generic, all-inclusive term.
