Whose name is attached to the giant extinct mammal discovered in South America known as Megatherium?

Georges Cuvier, the French naturalist and comparative anatomist, helped establish the study of extinct animals. Megatherium, a giant ground sloth from South America, became one of the most famous examples of a vanished mammal in his era. Cuvier’s work on fossils supported the idea that extinction was real, which was a major scientific breakthrough. Giant ground sloths were enormous herbivores that survived until relatively recently in geological terms.
