The Paramyladon, an extinct genus of ground sloth, was native to North America. It lived from the Pliocene era to the Pleistocene era, a period of about 4.889 years. Remains of this creature have been found as far south as Guatemala, throughout North America, and even as far north as Alberta, Canada. Paramyladon has been easily mistaken with another ground sloth called Glossotherium, due to major similarities. Barnum Brown created the Paramyladon genus in 1903 with a species of P....

Although related to the Megatherium , a much larger and more well-known ground sloth, Nothrotheriops was recently placed in the family Nothrotheriidae.  It migrated from South America about one million years ago. The Nothrotheriops has been found as far north as Alberta, Canada, causing it to be one of the most northerly of its kind. However, they primarily lived in the southwest in states...

Ground sloths are extinct edentate (Superorder Xenarthra) mammals that are believed to be relatives of tree sloths and three-toed sloths. They may have died out as recently as 1550 in Hispaniola and Cuba, but had long since been extinct on the mainland. The four identified species found in the United States consist of Harlan's Ground Sloth (Paramylodon harlani), Jefferson's Ground Sloth (Megalonyx jeffersonii), Laurillard's Ground Sloth (Eremotherium laurillardi), and the Shasta Ground...
