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.
