The first New World occurrence of the Eocene birdPlesiocathartes (Aves: ?Leptosomidae)

  • Ilka WeidigEmail author


Two new species of the Eocene avian taxonPlesiocathartes (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-rollerLeptosomus discolor. So far, putative fossil Leptosomidae have been found only in the Eocene European de-posits 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.

Zwei neue Arten des eozänen VogeltaxonsPlesiocathartes (Aves: ?Leptosomidae) werden beschrieben. Sie entsprechen in Größe und genereller Erscheinung sowohl den anderen Vertretern dieser Gattung als auch dem rezenten KurolLeptosomus discolor aus Madagaskar. Bis jetzt wurden putative Vertreter der Leptosomidae nur in Europa in den Eozänen Ablagerungen von Messel, Geiseltal, Quercy und dem London Clay gefunden. Beide neuen Arten stammen aus der untereozänen Green River Formation (USA) und sind damit die ersten neuweltlichen Vertreter dieses Taxons.
