EOCYPRAEA SP. View in CoL

FIGS. 8J–L View Figure 8

Cypraea View in CoL n. sp. Smith, 1975. p. 469, 479, pl. 2, fig. 10 [as Cypraea sp. ]. Groves and Squires, 2021. p. 227.

Referred Specimen—Hypotype (of Smith, 1975) CASG 61666.04 [ex LSJU 10236, ex LSJU 6582] ( Figs 8J–L View Figure 8 ), CASG Locality 61666 [ex LSJU Locality 2073; = UCMP Locality A-9717].

Occurrence— Basal part of Lodo Formation, late Paleocene (Thanetian Stage). Tumey Hills, Fresno County, central California .

Remarks— Only a single specimen is known, and Smith (1975) provided only a lateral view. This view, as well as the basal and dorsum views, are also shown in this present paper. The aperture is filled with matrix, but otherwise the specimen has fairly good preservation. However, key features are obscured and a species name cannot be assigned at this time.
