When carnivores kill other carnivores...

[Guy Leahy <xrciseguy@sbcglobal.net>]

This certainly has potential applications for dinosaur
ecosystems:

Off the top of my head, I can't think of too many
dinosaur faunas which include two big theropods of
approximately equal size (Albertosaurus/Daspletosaurus
does come to mind.)  Are there any other examples?
