Hispaniola monkey

The Hispaniola monkey (Antillothrix bernensis) is an extinct primate that was endemic to the island of Hispaniola, in the present-day Dominican Republic, and died out sometime during the Holocene. Its oldest specimen dates to about 1.32 million years ago, in the Early Pleistocene, while the holotype was dated to about 3,850 radiocarbon years before present. Researchers have proposed that all the Antillean monkeys, including the Cuban Paralouatta and the Jamaican monkey, form one group most closely linked to the living titis. A skull found by a diver in 2009 in La Jeringa Cave, in Cotubanamá National Park, suggested that it was active by day because of its relatively small eye sockets, and new specimens from Cueva Macho published in 2024 suggest a variable but monomorphic species. It is suggested to have been a generalised fruit eater and a capable climber.
