Here's something that palaeontologists have been arguing about for years. Was T-Rex an active hunter or nothing more than a scavenger? Personally, I think it was both. What do you think?

Well, if all the smart, actual Ph.d holding Paleontologists can't agree, I've got no clue.
Like most predators, It was probably eating whatever it could find, with minimal risk to itself, which could mean scavenging.
Almost all bear species' today live primarily as vegetarians, with some larger species also mixing in fresh fish, or scavenged deer/elk etc. The only species who is predominately an active hunter is the polar bear, but that's more to do with its environment than a choice. The theory about the T-Rex being a scavenger has to do with physiology; They believe its bone structure wouldn't allow it to run, or fight effectively. Assuming there's just a fragment of truth to that idea, being a scavenger primarily makes sense, either do its physical limits, or just an easier, risk free way to live.

Some predators rely on speed, some build traps or use venom and some rely on ambush. Perhaps T-Rex didn't need to be awfully fast to be a successful hunter. The eyes faced forwards which gave them binocular vision. In modern times, this kind of vision is found mostly in predatory animals. It also had a well-developed sense of smell and a bone-crushing bite force of more than 430psi, the most powerful bite of any known land animal. Partially-healed bite marks on the bones of Hadrosaurs and Ceratopsians prove that there was some kind of interaction between T-Rex and a living target. There's also the possibility that T-Rex hunted in packs, with the juveniles chasing the prey and the adults making the kill.

Ever since the research suggesting that T. rex can't run, I had thought that a suitably motivated human could escape therefrom. And likely you would agree that there's hardly any better motivation! Now with this juvenile thing though, well... I'm lunch!

Fossils suggest that some Tyrannosaurs hunted in family groups. In August 1910, American palaeontologist Barnum Brown discovered more than twenty Albertosaurus skeletons in a quarry near Canada's Red Deer River. The group consisted of nine adults, seven sub-adults and six juveniles.

Scavenger, it doesn't or didn't have the means with its front arm to do anything, looking at hunter killers of the say, T rex was not a hunter

New research has suggested that T-Rex's arms were quite strong, capable of lifting up to 200kgs. The only reason the arms look so small is because of the overall size of the body. Each arm was around three feet long and the fingers had large curved claws. We don't know the exact function of the arms, but it's possible that, at close quarters, they may have been used to stab or slash at prey. It's also possible the arms were used to help T-Rex get back on its feet after sleeping on the ground. Males may also have used their arms for holding tight to a female during mating.
