So I just finished watching Valley of the T-Rex and though I accept Jack Horner's opinion about T-Rex being just a scavenger. I still think T-Rex was both a Predator and a Scavenger.



So what do you guys think T-Rex is in your opinion. A Hunter, Scavenger or Both?

Both, although more scavenger than hunter.

It's actually both. Despite what Jack Horner claimed

it´s impossible for a terrestrial animal to be a 100% scavenger. It would have eaten everything that it could get, like a lion or hyaena, but it would have hunted it´s prey itself most of the time.

Jack Horner has also changed his own opinion about tyrex. He admits now it was both hunter and scavenger.

Yeah...there is nothing in that documentary that I find terribly convincing for a "primarily scavanger" lifestyle.

A good sense of smell is an extremely useful tool for a predator, so are bone crushing/armor piercing teeth, especially if you are taking on armored or really big and dangerous dinosaurs.

I don't find the "it'll trip and kill itself" argument convincing either. When was the last time you saw an ostrich trip?

An ostrich isn´t that large. But that would mean that all large theropods were slow scavengers, while we have scientific estimates for carnotaurus to be extremely fast (I don´t know, was there a specific figure?) and even for giganotosaurus to reach 50km/h.

This question is ridiculous! We already have evidence for both, we found T rex bite marks on a Triceratops, who was already dead and some on a frill, which healed. Carcasses don't heal. That's enough evidence! Also we have no 100% Scavengers in our world, so I doubt that T rex was one!!!!!!

We have 100% scavengers: vultures
But the difference is, that a flying animal can cover vast distances very efficiently and that it can also pick up smells from a much better position.

They aren't 10% scarevengers, they attack small animals(like animal babys).

Do they. anyway, Some vultures are the closest any animal can get to being a pure scavenger. Such a percentage of scavenging is only possible for a flying animal or for microorganisms.

I've seen records of them, trying to attack AWD babys.

Tyrannosaurus had rather good vision. Also smell is used by many predators like Wolfs as well. Valley of the T. rex had several outdated facts Don't use it for reference. Prey like Triceratops weren't very fast, if T. rex couldn't run. Most large dinosaurs had longer femur than tibia too. Even this dinosaur was slower than prey, it would be ambush hunter. There was not that large animal which was pure scavenger. Tyrannosaurus was only large carnivore in ecosystem. Most, if not every hunters are scavengers from time to time, even Velociraptor would scavenge on dead bodies. So i think Tyrannosaurus is both predator and ocasionally scavenger.

The only logical answer is both. There's hardly any(if any) animals that purely hunt or purely scavenge. T.Rex was probably the top predator in it's area, and therefore, we need to look at apex-predators today. Take Lions, they neither hunt or scavenge purely, they do both. T.Rex was probably the same.
