Project Antillothrix is a multi-organizational partnership formed to conduct biodiversity surveys and excavations of paleontological cave sites in the Dominican Republic. Together, researchers and divers from the City University of New York (CUNY), Universidad Autónoma de Santo Domingo (UASD), Museo del Hombre Dominicano (MHD), and the Dominican Republic Speleological Society (DRSS) have documented and collected a trove of vertebrate fossils for study and preservationsince the inception of this collaboration in 2011.

Among these finds are a nearly complete skeleton and several isolated elements of the extinct monkey Antillothrix bernensis, the best-preserved primate fossils in the Caribbean. This development has had a great impact on our knowledge of the enigmatic, now extinct Caribbean primate radiation, and it stands to have far-reaching effects on our understanding of the natural history of the region and its much-diminished biodiversity.
