birds 
Assuming that all birds living today are descended from bird species that survived the KT extinction, what fossil evidence has been found that shows a continuity across the boundary for those species?...
Can present day birds be correctly referred as Dinosaurs? Or just be surviving ancestors of the Dinosaurs?
We've had a number of posts (and debate) about birds, proto-birds and the like recently.
I'd like to change the emphasis a bit and am asking if anyone can point me to good sources of ref...

I have one tiny problem with this being the death knell of the birds = dinosaurs theory: if birds couldn't possibly be related to therapod dinosaurs because the therapods had a hepatic piston sys...
Birds did undergo radiation in the Cretaceous. The problem is that these aren't modern birds. Cretaceous birds that are ancestral to the modern orders would indeed support Cooper and Penny but I ...

Good Question. I really don't know how many fossils of birds we have. I guess it referrs to what I call the "Bird-Dino Theory."

Cormorants are very long necked birds that pursuit their prey underwater. I have seen shags swim after fish and twist their neck in the last moment to grab a prey. These birds are very fast swimmers t...
