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

[Thomas Richard Holtz <tholtz@umd.edu>]

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
