Predators with poor camouflage?

[Doorhandle]

That's been a theory for a long time.

The presence of partially healed T. rex bite marks on herbivore bones though, strongly suggests otherwise - that T. rex tended to attack live prey rather than dead prey, with the prey sometimes escaping with scars to tell the tale.

Related: I remember a scientific paper that posited that they were actually an anti-Ceratopsian specialist, and they had the highest bite strength of any carnosaur. But I will note that very few predators would actually pass up carriorn.

Also, prey species that are highly poisonous tend to be brightly colors, so predators realise they're poisonous and leave them alone. This may just be me being gonzo, but I am highly amused by a) the idea of poisonous carnosaurs and b) a predator big enough to regularly target carnosaurs. But it's easily the least logical option here.
