The first new fossils of Xenothrix mcgregori discovered in 70 years--a femur and a humerus--were found by an AMNH expedition in caves at Jackson's Bay on the south coast of Jamaica in August, 1993. These finds closely resemble specimens from Long Mile Cave previously allocated to Xenothrix by MacPhee and Fieagle (Bull. Amer. Mus. Mar. Hisr. 206: 287-321 [1991]), and help to support the argument that this primate was a slow quadruped. The new material comes from the driest part of the island, which currently supports xerophytic bush rather than humid forest. Since there is evidence that this region was wetter in the past (?middle Holocene), human arrival may not have been the only stress factor pushing Jamaican mammals to extinction.
