Description
TYPE SPECIMEN: AMU-CURS 98 (Gaffney et al., 2008).
TYPE LOCALITY: North of El Picache, Urumaco Formation, state of Falcón, Venezuela.
HORIZON: Late Miocene, Urumaco Formation.
DIAGNOSIS: A species of Bairdemys differing from all other Bairdemys species in having an elongate, narrow snout with the labial ridge concave in ventral view, and a wide basisphenoid-quadrate contact; also differs from B. hartsteini in having a larger skull and no premaxillary notch; also differs from B. venezuelensis in having a narrower skull, a wider posterior triturating surface, no premaxillary notch, and a longer midline pterygoid contact; also differs from B. sanchezi in having a larger skull, a larger, anteriorly wider, basisphenoid, and a less extensive temporal and cheek emargination.
REFERRED MATERIAL: Probably AMU-CURS 96, AMU-CURS 97, and AMU-CURS 99, belong to this species, as these specimens have elongate snouts. The specimens come from the same stratigraphic level (quarry level) at the El Picache locality (11 ° 14 9 40 0 N, 70 ° 14 90 4 0 E; top of the upper member in the Urumaco Formation). This locality represents the eastern equivalent of the ‘‘capa de Tortuga’’ located in Corralito (also top of the upper member).
PREVIOUS WORK: Sánchez-Villagra and Winkler (2006).
DISCUSSION: This species is described and figured in Sánchez-Villagra and Winkler (2006) and Gaffney et al. (2008). Its large size, elongate snout, and concave labial ridges are characteristic.
