摘要
A cranium of the extinct Cuban Macaw Ara tricolor from a Quaternary sinkhole in Villa Clara Province, Cuba, is the third paleontological record for the species in Cuba or for any macaw in the West Indies. The specimen also constitutes the northern and easternmost proven occurrence of the species and adds further information bearing on the osteology and size of Ara tricolor relative to other members of the genus. Aquatic depositional environments may be important for determining the true distribution of macaws in the West Indies through the fossil record.
