Genus: Anseranas
Description
Taxonomy
Anseranas is a monotypic genus in the family Anseranatidae.
Clements formerly included this genus in the family Anatidae. However, this sub-family is quite old, having apparently diverged before the extinction of the dinosaurs. The fossil record is limited, nonetheless, with an undescribed species from the Late Oligocene of Billy-Créchy (France) being known (Hugueney et al, 2003). The enigmatic genus Anatalavis (Hornerstown Late Cretaceous/Early Paleocene of New Jersey, USA - London Clay Early Eocene of Walton-on-the-Naze, England) is sometimes considered to be the earliest known anseranatid.
