Oh, the ignorance in this thread. Tyrannosaurus wins this; it was NOT a cowardly, complete scavenger (anyone who still believes that is either ignorant, biased (against T.rex), or both), and it could IMO outmaneuver Megatherium. There is a paper which stated theropods would change their body posture to improve their agility. They would lift their tails up, make an S-shape with their neck, and pull their arms back. I'll give a link to the paper to anyone who thinks theropods are unagile. And T.rex's bite will certainly kill Megatherium if bitten on the neck. T.rex 6/10.

The Trex is extremely over rated by the looks of it's bio-mechanics the t-rex does seem like it would have any balance if attacked from the side. Meg on the other hand has firm tripod base stance and has been believed to tip gylptodont (not saying is predatory they could just be d-bags like hippos that kill for no reason). Also I know T-rex obviously weighs a lot more than a gylptodont, but this behavior shows that the would have a fighting style similar to a bear trying to pen a maul to death it's opponent. I think the sloth could easily tip T-Rex and maul it to death especially if it had similar pound for pound strength as modern sloth which can climb a tree with a cougar on it's back. Meg is supposed to be a lot faster than modern sloths and if it's anything like another one of it's relatives the anteater it can swipe with blinding speed, not saying it run fast though. Anyway at even weight I would give it to the sloth by land slide with T-rex having a small chance if it can land a head bite which is unlikely since Meg is taller and if T-rex tried to jump it would break it's hips. Also their is not much evidence of T-Rex even hunting large prey as most bite on Triceratops horns are healed over mean the herbivore was most likely the aggressor along with fact it can't chew and obviously can't do anything like a death roll mean it likely ate food it could swallow whole the only thing that suggest T-rex hunting large game was the fact they live in packs which I'll admit they could work together to tear apart bite size pieces to swallow. The point is we don't know enough about the animal to know if it would even view Meg as prey since predator tend to fight other predator differently than they tackle prey animals. Bottom line Meg hold most the advantages in this fight.

1.) Am I the only one sick of hearing things as if theropods were (or are) baby animals just beginning to walk? 2.) Good luck tipping over a similar sized or if anything substantially more massive heavily built theropod. 3.) Ground sloths and tree sloths (obviously) adapted to different lifestyles, thus doing different physical activities. I don't know if taking tree sloth feats and scaling them up to make them apply to Megatherium with a different lifestyle is accurate. I'd also like to see your source for the claim that modern sloths can climb trees with cougars on their backs. 4.) Yeah, I'm not sure if Megatherium's going to be faster than modern sloths given how it weighs so much more. 5.) Megatherium's not that tall, if you're thinking of it being ~6m tall, well, it isn't. In fact, some of the largest specimens likely wouldn't be much taller than the largest rex (so no, no jumping is required). 6.) Healed bite marks just mean the prey survived the attack, it by no means shows the prey being the aggressor is more likely (in fact, wouldn't one of the most plausible scenarios have the T.rex being the aggressor only for the Trike to survive? The rex is the predator after all). 7.) ROFLMAO in regards to feeding. Theropods did not (and still do not) need to masticate to feed on flesh, they simply bite a selected area, pull back a chunk of flesh and use something called inertial feeding (throwing the bitten piece a bit into the air to get it further into the mouth and swallow).
