Ceratocyrtis sp. F

Plate 12, Figs. 9A –11.

Ceratocyrtis sp 10, Trubovitz et al., 2020, supplementary data 7.

Remarks. This species typically has a slightly thorny cephalis and thorax, with small, regular pores, and one slight dimple on thorax. The cephalis exhibits one main forked spine. This species is very similar to Ceratocyrtis sp. E (pl. 13, figs. 7A–8), but differs in that the primary cephalic horn is forked.

Material examined. 54 specimens observed from samples 321-1337D-23H- 6, 134–137cm (Late Miocene), 321-1337A-18H-6, 77–80cm (Late Miocene), 321-1337A-16H- 6, 121–124cm (Late Miocene), 321-1337A-14H-7, 39–42cm (Late Miocene), 321-1337A-12H-5, 23–26cm (Late Miocene), and 321-1337A-5H-5, 11–14cm (Late Pliocene).

Range. Late Miocene—Latest Pliocene, EEP ( Table 1 ).
