One extinct species is the 'western' black vulture,
Coragyps occidentalis, a larger ancestral relative of the modern species which lived in
North America during much of the
Pleistocene epoch; however, genetic evidence indicates that
C. occidentalis may not be a true species of its own, as it is nested within the modern black vulture. The other is the Cuban black vulture,
Coragyps seductus, known from the Pleistocene of
Cuba. ==References==
