Neocathartes is an extinct genus of cariamid bird. It contains a single named species, Neocathartes grallator ("walking new turkey vulture"), known from some fossil bones found in Late Eocene (c. 37-34 mya) Washakie Formation deposits of Wyoming. Similar bones have been recovered from the Early Eocene Willwood Formation. The genus originally set up by Wetmore, Eocathartes, was already in use for an unrelated fossil bird from Germany, so a new genus had to be established for the Wyoming fossil.[2]

Initially mistaken for a walking New World vulture, Neocathartes is now classified as a bathornithid, a family of cariamaeans. Neocathartes was a slender bird, around the size of a turkey vulture. Although it was capable of flight, it probably stayed on the ground most of the time, as evidenced by its long legs. Its lifestyle was most likely comparable to that of the modern-day secretary bird, or the seriema (to which the bathornithids were distantly related).[3] Posterior bathornithids would have lost flight altogether, and reached particularly large sizes.[4]

The misattribution of Neocathartes was resolved by Storrs Olson.[5] Usually a serious, no-nonsense scientist, he could not help noting,

The reconstruction published with the original description of Neocathartes has often been reprinted and has now made the "terrestrial vulture" an integral part of the lore of avian paleontology. Well, forget it.

Neocathartes is just our old friend Bathornis in another guise.

He considered the genus Neocathartes a junior synonym of Bathornis. This was usually rejected by subsequent studies, but more recently Gerald Mayr et Jorge Noriega 2015 have recovered Neocathartes within Bathornis.[6]
