A study of avian fossil material from the Upper Pliocene of Nebraska
has revealed the presence of a new genus and species of turkey
(Meleagrididae) . The type specimen and the referred material are deposited
in the University of Nebraska State Museum Collections (UNSM) .
This material, including two left coracoids (UNSM 20033, complete and
20034, humeral %), two 0 tarsometatarsi (UNSM 20037, lacking trochlea
and 20035, proximal %) , and a spur core (UNSM 20036)) was collected from
the lower part of the Kimball Formation, UNSM Coll. Lot. Ft-40, south of
Lime Creek in Frontier County, Nebraska. The Kimball Formation is the
upper formation of the Ogallala Group and is older than the San Pedro
Formation of Arizona and the Rexroad Formation of Kansas, in which
Agriocharis progenes Brodkorb occurs. A discussion of the stratigraphy of
the Ogallala Group is outlined by Schultz and Stout (1961:7,9, Fig. 3).
Vertebrate fauna1 lists for the Kimball Formation have been published by
Schultz and Stout (1948:557, Table l), modified by Kent (1963:14, Table
1) and include: Megalonyx; Hypolagus; Perognathus; Thomomys; Dipoides
stirtoni Wilson; Dipoides williamsi Stirton; saber-toothed tiger (undet.) ;
Amebelodon fricki Barbour; Teleoceras; Neohipparion; Pliohippus (Astrohippus)
; Pliohippus (Dinohippus) ; Nannipus; Prosthenops; Procamelus;
Pliauchenia; Cranioceras; Texoceros guymonensis Frick; Sphenophalos
middleswarti Barbour and Schultz; Cite&s kimballensis Kent; and Aphelops
kimballensis Tanner.
