Amazonetta cubensis

Amazonetta cubensis (also known as the Cuban teal) is a species of duck in the family Anatidae that lived in Cuba during the Pleistocene epoch.^[1] It is a relatively small species of duck similar in morphology to the extant Brazilian teal, however, the shaft was thinner and more steeply oriented.^[2]

The scientific name of this species is referencing its occurrence in Cuba. The common name Cuban teal has been suggested because of this.^[2]

Discovery

A complete humerus (PIN 5781/40) was discovered and given the classification of a new species. The fossil was discovered in western cuba in the El Abrón Cave strata which was dated to the late Pleistocene epoch.^[1][2]

The evolutionary history and past diversity of ducks in the West Indies is largely unknown due to a poor fossil record of birds in the region. This makes the discovery of this species important for uncovering the history of ducks in this region.^[1] The closest living ancestor of A. cubensis is a Brazilian species named Amazonetta brasiliensis (Brazilian teal). This has means that Amazonetta had a wider distribution during the late Quaternary period.^[2]
