Megatherium v Therizinosaurus

Megatherium americanum
Megatherium ("Great Beast") was a genus of elephant-sized ground sloths endemic to Central America and South America that lived from the Pliocene through Pleistocene existing approximately 5.3 million years. Its size was exceeded by only a few other land mammals, including mammoths and the even larger Paraceratherium. Megatherium was one of the largest mammals known, weighing up to eight tons, about as much as an African bull elephant. Although it was primarily a quadruped, its footprints show that it was capable of assuming a bipedal stance. When it stood on its hind legs it was about twenty feet (6 m) tall, twice the height of an elephant. This sloth, like a modern anteater, walked on the sides of its feet because its claws prevented it from putting them flat on the ground. Megatherium species were members of the abundant Pleistocene megafauna, large mammals that lived during the Pleistocene epoch. Megatherium had a robust skeleton with a large pelvic girdle and a broad muscular tail. Its large size enabled it to feed at heights unreachable by other contemporary herbivores. Rising on its powerful hind legs and using its tail to form a tripod, Megatherium could support its massive body weight while using the curved claws on its long forelegs to pull down branches with the choicest leaves. Its jaw is believed to have housed a long tongue, which it would then use to pull leaves into its mouth, similar to the modern tree sloth.

Therizinosaurus cheloniformis
Therizinosaurus (play /θɛˌrɪzɨnɵˈsɔrəs/; 'scythe lizard', from the Greek therizo meaning 'to reap' or 'to cut off' and sauros meaning 'lizard') is a genus of very large theropod dinosaur. Therizinosaurus lived in the late Cretaceous Period (late Campanian-early Maastrichtian stages, around 70 million years ago), and was one of the last and largest representatives of its unique group, the Therizinosauria. Its fossils were first discovered in Mongolia and they were originally thought to belong to a turtle-like reptile (hence the species name, T. cheloniformis — "turtle-formed"). It is known only from a few bones, including gigantic hand claws, from which it gets its name. Though the fossil remains of Therizinosaurus are incomplete, inferences can be made about its physical characteristics based on related therizinosaurids. Like other members of its family, Therizinosaurus probably had a small skull atop a long neck, and had a bipedal gait and a heavy, deep, broad body (as evidenced by the wide pelvis of other therizinosaurids). Its forelimbs may have reached a length of 2.5 metres (8 feet) or even 3.5 metres for the largest known specimen. Its hindlimbs ended in four weight-bearing toes, unlike other theropod groups, in which the first toe was reduced to a dewclaw. Gregory S. Paul in 2010 estimated the length of Therizinosaurus at ten metres, the weight at five tonnes. It is the largest therizinosaur known and the largest known member of the Maniraptora. The most distinctive feature of Therizinosaurus was the presence of three gigantic claws on each digit of its frontlimbs. These were common among therizinosaurs but especially large in Therizinosaurus, and while the largest claw specimens are incomplete, they probably reached just under 1 metre (3.28 ft) in length. The claws are the longest known from any animal. The claws were relatively straight, only gradually tapering into a point, and extremely narrow, transversely flattened.

^Yeah, now I understand. I still vote Megatherium though. 100% rates are something like Human vs House Mouse. 100% rates are very rare and are only used if one opponent had a SIGNIFICANT size advantage against the other.

Evolution isn't about becoming better and better.
He doesn't believe in evolution.
In that case his statement makes even less sense.
How can someone not "believe in evolution"? I'm always asking myself this when I hear of ignorant people who think evolution was a matter of belief. Can anyone give me an explanation for, well, evolution or however you call the way life has evidently evolved on this planet, that makes sense, apart from natural and sexual selection?
If nobody can, which I think is a certainity, then evolution to date is a fact, not a matter of personal opinion.

Therizinosaurus has better weapons.
The Megatherium's claws look like better weapons, they are more robust and the Therizinosaurus' claws look weak and the sloth has chain-mail armour.

Megatherium wins, usually because of the fact that it is more robust than the theropod and like, theropod said, likely has the stronger swipe. When looking at their builds, it just seems the sloth is stockier and would be harder to kill. But the supposed "chain-mail" armor is very overrated and can very likely be pierced, and I don't doubt Therizinosaurus's 1 meter long claws can penetrate it. However, as I said, the sloth's greater bulk and stronger attacks will save it.

People are saying that zinos claws are not effective weapons. Wrong. They provide a bit of range, and they fought off huge theropod predators with them. Also, the mega thorium may have armor, but zino could attack the head. Even if it doesn't attack the head, it can still make cuts and cause blood loss. And it wasn't hard to control the claws, either. I noticed some people say that. And I know that meg probly did have a strong swipe, but that could be avoided. Go therizinosaurus!

Megatherium is the more robust of the two as well as the better armoured. Therizinosaurus' weaponry may be more formidable in my opinion, but I don't think they will be able to cause serious damage before it is knocked down and seriously mauled. I do think that Therizinosaurus is probably the more agile of the two though and this could pose a serious problem to the sloth.

I have the impression that this sloth would massacre a Therizinosaurus...

This is really the greatest battle of claws vs claws. Main factors for me are claws, power, and defense. The therizinosaurus has longer claws, while the megatherium had a more powerful swipe. The sloth is all about power, they stand a little higher and is probably the more robust and powerful animal. The therizinosaurus was strong too, but I don't don't think had the arm strength of the sloth. The sloth also had a sort of natural armor. With all that considered, the mammal wins for me.

No, megatherium stood at 6 meters tall. It was taller than therizinosaurus.

No it's not. 6 meters (and 8 tonnes) is an exaggerated fabrication that IIRC, wasn't stated in any scientific source. Megatherium wasn't even close to 6 meters tall.
