Neocnus is an extinct genus of ground sloth, whose species ranged across Cuba and Hispaniola (Haiti and Dominican Republic). They have been dated to as recently as 4391 BP, calibrated to c. 5000 BP. It is theorized that this sloth, in common with other Antillean sloths, was killed off by humans seeking its pelt and meat.
Euphractus sexcinctus, the six-banded armadillo, also known as the yellow armadillo, is a species of armadillo from South America.
