Paralouattais aplatyrrhinegenusthat currently contains twoextinctspecies of smallprimatesthat lived on the island ofCuba.
Description
[edit]Paralouatta varonaiwas described from a nearly completecraniumfrom the lateQuaternaryin 1991. This cranium and a number of isolated teeth and postcranial bones were found in theCueva del Mono,a cave site inPinar del Río Province.The initial description of the cranium included a proposal thatParalouatta varonaiwas a close Caribbean relative of the extantAlouatta(howler monkeys) of Central and South America,[1]but this taxonomic placement was called into question with the analysis of the dental remains.[2]Based on shared similarities with the three other Caribbean monkeys,Xenothrix mcgregori,Insulacebus toussaintiana,andAntillothrix bernensis,MacPhee and Horovitz have proposed that the Caribbean primates are part of a monophyletic radiation which entered the Caribbean at theOligocene–Mioceneboundary. Further research confirms this assessment and places these three species in the tribeXenotrichini.[3]However, more recent research restores its close relationship withAlouatta.[4]The postcranial morphology ofParalouattasuggests that it was partly terrestrial,[5]and a likely example ofisland gigantism.[6]
A second species ofParalouatta(P. marianae) has also been described from theBurdigalian(~18 million years old)Lagunitas Formationand is the largestNeotropic primateknown of that epoch.[6]
Paleobiology
[edit]Paralouattahad an estimated body mass of 8.4 kg (19 lb).[4]Analysis of postcranial morphology suggests thatParalouattawas at least somewhat semi-terrestrial, making it the most terrestrial platyrrhine genus known.[7]
