Acratocnus is an extinct genus of Caribbean sloths that were found on Cuba, Hispaniola (today the Dominican Republic and Haiti), and Puerto Rico during the Late Pleistocene and early-mid Holocene. Taxonomy
Megalocnidae is an extinct family (alternatively considered to be a superfamily as Megalocnoidea) of sloths, native to the islands of the Greater Antilles from the Early Oligocene to the Mid-Holocene. They are known from Cuba, Hispaniola and Puerto Rico, but are absent from Jamaica.
Acratocnus odontrigonus, a sloth known only from Puerto Rico. Acratocnus major, described on the basis of somewhat larger Puerto Rican sloth bones, simply represents large individuals of A. odontrigonus. [32] A small sloth femur has been found at an early Oligocene site in southwestern Puerto Rico. It is not sufficiently diagnostic to permit ...
Ground sloths had dispersed into the Caribbean already by 31 million years ago, as evidenced by a femur found in Puerto Rico. [34] During the Miocene, sloths diversified, with the major families of sloths appearing during this period, [34] with diversity waxing and waning over the course of the Miocene. Megalonychid and mylodontid sloths had ...
Megalocnus ("great sloth" in Greek) is a genus of extinct ground sloths that were native to Cuba during the Pleistocene and Holocene epochs. They were among the largest of the Caribbean sloths (Megalocnidae), with individuals estimated to have weighed up to 270 kg (595 lbs) [1] to 200 kg (440 lbs), around the size of a black bear when alive.

This is a list of the mammal species recorded in Puerto Rico. These are the mammal species in Puerto Rico, of which one is critically endangered, none are endangered, two are vulnerable, and none are near threatened. Two of the species listed for Puerto Rico are considered to be extinct. [1]
Distinct Puerto Rican words like "jevo,", "jurutungo" and "perreo" have been submitted to Spain's Royal Academy- considered the global arbiter of the Spanish language.
Numerous ground sloths, some of which reached the size of elephants, were once present in both North and South America, as well as on the Antilles, but all went extinct following the arrival of humans. Extant two-toed sloths are more closely related to some extinct ground sloths than to three-toed sloths. Suborder: Folivora
