Re: [dinosaur] Was T. rex subadult a dominant predator in its environment?

Good day, thank you for your response. I know there is no direct evidence of gregarious behaviour in dromaeosaurid theropod dinosaurs, but isnÂt it highly plausible because of its obvious advantages? In a pack, dromaeosaurids would be much more efficient hunters and it could even be an adaptation for living along large tyrannosarids (as a mean of chasing subadults from their prey, etc). Thank you, Tom

You are presupposing that Dakotaraptor lived in packs. There is no evidence at present to determine that.

Certainly there would have been overlap between Nano-sized T. rex and Dakotaraptor in prey size. And as today, it is likely that rival predators engaged in kleptoparasitism all the time (just as hyenas & lions chase each other from kills).

Good day to all listmembers,

I was wondering if T. rex subadult (say 10 - 15 years old) was a dominant predator in its environment, just as an adult individuals. Could e. g. a pack of Dakotaraptors chase it away from its prey? Thank you for any thoughts! Tom
