Taphrosphys sulcatus

Osteichthyes - Testudines

Taxonomy
Platemys sulcatus was named by Leidy (1856) [Locality and Horizon. "Tinton Falls, N.J." (Leidy, 1865, p. 109). No further information is available. The locality has not been relocated and the horizon of the type is not known.]. Its type specimen is AMNH 2522, a partial shell (fifth, sixth, and seventh left peripherals and left xiphiplastron), and it is a 3D body fossil. Its type locality is Tinton Falls (Greensand), which is in a Maastrichtian marine sandstone in the Hornerstown Formation of New Jersey. It is the type species of Taphrosphys.

It was recombined as Prochonias sulcatus by Cope (1869); it was recombined as Taphrosphys sulcatus by Hay (1902), Hay (1908), Hay (1930), Wood (1975), Gaffney (1975), Lapparent de Broin and Werner (1998), Gaffney et al. (2006).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
E. S. Gaffney 1975Plastron relatively narrower than in T. olssoni; xiphiplastral notch shallower and not so circular as in T. olssoni; anterior plastral lobe relatively longer than in T. olssoni; xiphiplastral points more lateral compared with T. olssoni.
E. S. Gaffney et al. 2006A bothremydid pleurodire of the genus Taphrosphys distinguished from the other two species as follows: from T. congolensis: premaxilla labial ridge shallow not deep; rostrum basisphenoidale short and flat, barely defined; sella turcica shallow and wide; dorsum sellae low; processus clinoideus small; processus inferior parietalis farther from midline than in T. congolensis. Distinguished from T. ippolitoi: quadrate shelf not expanded laterally; sulcus eustachii opens ventrally rather than posteroventrally; fossa precolumellaris absent; sulcus eustachii without lateral process; premaxilla narrow; fenestra postotica not subdivided; tuberculum basioccipitale smaller; cavum tympani shallow rather than deep. Shell distinguished from ‘‘Taphrosphys’’ olssoni by plastron relatively narrower than in ‘‘T.’’ olssoni; xiphiplastral notch shallower and not as circular as in ‘‘T.’’ olssoni; anterior plastral lobe relatively longer than in ‘‘T.’’ olssoni; xiphiplastral points more lateral compared with ‘‘T.’’ olssoni.
