Name

  • †Axestemys cerevisia Vitek, 2012: 28, fig. 17
    • Holotype: UW 2382, a carapace, plastron, partial pectoral and pelvic girdles, and one cervical vertebrae.
    • Type locality: University of Wyoming Locality Number V-65004, NE 1/4 SE 1/4 Sec. 35, T 22N, R 113W, NE of Opal, Lincoln County, (Bridgerian) Bridger Formation, Bridger A, Wyoming, USA (Gaffney 1979).
Etymology: cerevisia, Latin for beer, in reference to the unusual method of data collection for the holotype specimen as reported by E.S. Gaffney: “The only information about the in situ position of the skeletal elements of this specimen is a field sketch made on a Coors beer six-pack container, another demonstration of the essential nature of this sort of field equipment”.

  • Trionychidae gen. indet.: Gaffney 1979: 53, fig. 1-3;
