Gymnogyps varonai
''Gymnogyps varonai'', sometimes called the Cuban condor, is an extinct species of large New World vultures in the family Cathartidae. ''G. varonai'' is related to the living California condor, ''G. californianus'' and the extinct ''G. kofordi'' either of which it may have evolved from. The species is solely known from fossils found in the late Pleistocene to early Holocene tar seep deposits in Cuba. ''G. varonai'' may have preyed upon carcasses from large mammals such as ground sloths.〔
==History and classification==
The species is known from at least six fragmentary fossils housed in the Museo Nacional de Historia Natural in Havana, Cuba, and includes a premaxilla, coracoid, the basal end of a right radius.〔 The specimens were collected from the Las Breas de San Felipe tar seep site San Filipe II, which is located west of Martí, Cuba. Based on the geology of the sites, the seeps are suggested to date from the Quaternary, being younger than the weathered serpentinites found under the seeps, and older than the of undisturbed topsoil which covers the deposits. A Pleistocene age has been given to both the mollusk fauna, studied in 1935 and the seed flora, studied in 1940.〔 The fossils were first studied by the Cuban Quaternary paleontologist Oscar Arredondo who described the species and placed it into a new genus ''Antillovultur'' as ''Antillovultur varonai''. The erection of the genus was subsequently questioned by other paleontologists, with Storrs L. Olson in 1978 suggesting it should was possibly a member of the genus ''Gymnogyps''. The fossils were fully redescribed in 2003 by William Suárez and Steven Emslie, who concluded that the species belonged to ''Gymnogyps'' and synonymized ''Antillovultur'' into the genus resulting in the species being ''Gymnogyps varonai''.〔
