Cartelles coimbrafilhoi

Cartelles coimbrafilhoi is an extinct very large New World monkey of the Pleistocene of Brazil, the only species of Cartelles. Its fossils come from the Toca da Boa Vista caves of Bahia, dated between roughly 360,000 and 10,000 years ago, and were first assigned to Protopithecus before a 2013 study showed distinct humerus and femur features that justified a new genus and species. The names honour the paleontologist Cástor Cartelle and the primatologist Adelmar Faria Coimbra-Filho. The single known individual, believed male, weighed an estimated 25 to 28 kilograms, more than twice any living New World monkey. It had an upturned snout, large incisors and a robust skeleton with suspensory ability like spider monkeys, and it is considered an alouattine related to howler monkeys. It is thought to have been fruit-eating and tree-dwelling, which suggests dense forest in Bahia then.
