Re: Theropod vs. synapsid: golden eagle kills sika deer in Russia

Golden eagles usually only resort to tackling such risky large prey during the 
winter, when smaller 
prey become scarce. If given a choice, they'd much rather be tackling something 
smaller and less 
risky (as would any carnivore).

It makes you wonder whether some of the predator/prey associations infered from 
the fossil record 
(Deinonychus/Tenontosaurus, Velociraptor/Protoceratops, etc) represent typical 
behaviour, or 
whether they represent rare occurances born out of occasional desperation.
