A sloth - but this is no ordinary sloth. This is Megatherium - a giant ground sloth. It has huge claws, is six meters from nose to tail, and weighs more than an elephant. A very different beast from its distant relatives, the gentle tree sloths.
— Allen, describing Megatherium

Megatherium (name meaning "Giant Beast"), sometimes called the Giant Ground Sloth, is a genus of elephant-sized ground sloth that originated during the Pleistocene epoch in what is now South America. Measuring 7 meters long and weighing 3 tons, it was one of the largest megafaunal mammals of all time.

In the episode "Saving the Saber Tooth", a pair of Megatherium were brought back to the park from Early Pleistocene South America, 1 million years ago. Unknown to the team that some youngsters and juveniles followed them through the time portal. They reside in the Ape-Man Jungle.


Era & DescriptionEdit

Megatherium lived in South America over 1 million years ago during the Middle Pleistocene. They shared their environments with other Ice Age animals like SmilodonPhorusrhacosMacrauchenia, DoedicurusToxodon, and GlyptodonMegatherium died out around 8,000 years ago, during the Holocene epoch.

The first fossil specimen of Megatherium was discovered in 1788 by Manuel Torres, on the bank of the Luján River in Argentina. 

Physical AttributesEdit

Megatherium was far from being a normal sloth. Possessing giant claws on their hands, they measured over 16 – 26 feet (5 – 8 m) in length, stood 13 feet (4 m) tall, and weighed 3 tons (6,000 lbs.), more than an adult elephant; a very different beast from their distant relatives, the gentle tree sloths.

These creatures also boasted impressive defenses. Small bones beneath their skin acted as a chain mail, therefore, Megatherium had powerful clawed forelimbs for attack and armor-plated skin for defense, rendering adults virtually indestructible. 

Behavior & TraitsEdit

Megatherium lived in pairs but were also solitary creatures. Even the apex predator of their region, Smilodon, wisely gave Megatherium a wide berth of space. Although Megatherium was a herbivorous mammal, they would occasionally eat carrion to supplement their diet, therefore making them omnivorous. And when they did, there was nothing that stood in their way, not even Smilodon. Even with such power, Megatherium was a gentle herbivore that only attacked other animals when in danger.



  • The sound effects of Megatherium are that of bear, boar, camel, elephant, and goat sound effects.
  • Megatherium is the largest and the only prehistoric sloth to be brought back to the park.
  • Megatherium is the largest South American mammal to be brought to the park.
  • Though described as being "virtually indestructible", large theropod dinosaurs, such as Tyrannosaurus rex, as well as large mammalian carnivores, Arctotherium for example, are capable of injuring and even killing Megatherium.
