Pictures Cuban sloth [6] Acratocnus antillensis: Cuba: Most recent remains dated to 5050-4050 BCE. [4] Puerto Rican sloth [6] Acratocnus odontrigonus: Puerto Rico [6] Most recent remains dated to 1738–1500 BCE. However this date was not obtained directly from bones, nor calibrated, and the remains could be older. [7] Haitian Macaya sloth [6 ...

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 ...
