摘要：
Two new species of the Eocene avian taxon Plesiocathartes (Aves: ?Leptosomidae) are described. They are similar in size and overall appearance to other members of the genus, as well as to the extant Madagascan cuckoo-roller Leptosomus discolor. So far, putative fossil Leptosomidae have been found only in the Eocene European deposits of Messel, Geiseltal, Quercy, and London Clay. Both new species are from the Lower Eocene Green River Formation (USA) and thus the first New World representatives of this taxon.
