C Plate 13, Figs. 1A – 2B . Ceratocyrtis sp 5 , Trubovitz et al., 2020 , supplementary data 7. Remarks. The cephalis of this species is relatively large for the genus. It has a strong conical apical spine that protrudes out the side of the cephalis before nearing the apex, which can have a slightly triangular shape in some specimens (as in pl. 13, fig. 1). This species has a tapering thorax, which is unusual among the Ceratocyrtis species observed in this study. The shell reaches its widest point approximately 1/3 down the thorax. Pore size is mostly uniform throughout the cephalis and thorax. Only three specimens were observed, so additional study is needed. Material examined. 3 specimens observed from samples 321-1337A-6H-3, 29–32cm (Late Pliocene), and 321-1337A-4H- 6, 115–118cm (Early Pleistocene). Range. Late Pliocene– Early Pleistocene in the EEP ( Table 1 ).
