Neophrontops is an extinct genus of Old World vulture. Despite being taxonomically an "Old World" vulture, specifically a member of the subfamily Gypaetinae, it was native to North America, with five species having been named, ranging from the Early Miocene to the Late Pleistocene. All except N. americanus are only known from fragmentary remains, though well-preserved remains are known from the Middle to Late Pleistocene-aged La Brea Tar Pits of Southern California.
Taxonomy
• N. americanus (Early Miocene to Late Pleistocene) Questioned whether all remains assigned to this species belonged to it, because "if it had corresponded to one biological species, it would have had an extraordinary vast existence." • N. dakotensis (Early to Middle Pliocene) Only known from a distal humerus • N. slaughteri (Late Pliocene) • N. vallecitoensis (Middle Pleistocene) • N. vetustus (Middle Miocene) Only known from a distal humerus, which only differs from that of N. dakotensis by the fact that it is about half the size ==References==
