Two things come to mind. One is theropods might have been warm blooded. Two is I'm thinking baby dinosaurs were predators and prey of each other. In other words, it looks a lot like the babies were doing all the same things the adults were doing from the look of those teeth and claws.
What the Archeopteryx story really shows is that it has become pretty pointless to differentiate between dinosaurs and birds. Sorry, Triceratops, you weren't the last; little dinosaurs are still everywhere, all around us (YAY).
Birds ARE dinosaurs. Sciencey types have already been referring to "non-avian dinosaurs" as a way to specify the lineages that didn't lead to birds for a while now.
@10: I KNOW RIGHT?
TAXONOMYRAEG!
Also in dinosaur news, my fossil prep skills have been steadily improving. Today I carefully removed about a millimeter-thick layer of matrix from a piece of scrap bone, barely touching the bone beneath the rock.
Hi, Mary!
