Giant sloth bone fossils

You will find many giant sloth bone fossils in our selection above. These fossils are regularly found by paleontologists in South America. They often come from private American collections. Giant sloth bone fossils can be expensive if the bone piece is long and in good condition. Smaller fragments are obviously much more affordable. These are mostly bone fossils of Eremotherium, Megalonyx and Paramylodon which were prehistoric sloths smaller than Megatherium.

Your questions about Giant Sloth fossils.

You have sent us many questions about giant sloth fossils. In this part we will take the time to answer the most frequent questions about these impressive prehistoric sloths. If you have other questions, don't hesitate to contact us. 

Where are giant sloth fossils found?

The fossils of Giant Sloths are found wherever the species lived. Concerning the most famous of the Giant Sloths: the Megatherium, we find these fossils in South America, particularly in Bolivia. Fossils of prehistoric sloths are found in other regions: Eremotherium in the southern part of North America and Pseudomegatherium in the Andes. The fossils are found during paleonthological expeditions or during deep constructions in areas formerly populated by giant sloths. 

Are giant ground sloths still alive?

No, all species of giant sloths are extinct. The last ones disappeared during the last ice age 11,000 years ago. The climate had become too cold for these mainly tropical species and human predation didn't help them too. The species of sloths still alive today in South America are not giant sloth species. 

What is the biggest sloth ever found?

The largest sloth ever found is a Megatherium whose skeleton was found in Bolivia in 1982. According to scientists, this specimen was 3.5 meters high (11.5 feet) and weighed about 4 tons. It is very far from the 4 kilograms that weigh our contemporary sloths. It is difficult to imagine the strength and size of this record-size giant sloth.

Is the giant sloth real?

Yes, they were real. There are dozens of giant sloth species that lived in North America and South America more than 11,000 years ago. The largest species was the Megatherium who lived in Bolivia and could weigh about 4 tons for a size of 3.5 meters ! 

How much is a giant sloth claw fossil worth?

A well-preserved giant sloth claw of the larger Giant Sloth species like the Megatherium can cost several thousand dollars. A Megatherium claw was sold for $6,000 in June 2022 on the website of one of our paleontologist friends. Smaller giant sloth claws can be found for around $200.

For smaller budgets, you will also find nice replicas of giant sloth claws at the bottom of our selection. This will particularly appeal to children to get them interested in prehistory and extinct animals.
