Eoconulus sp.

Fig. 10L, N .

Material.—Total of 3 dorsal valves. Figured specimens: RM Br133826, RM Br133827 (W = 0.70, L = 0.58).

Remarks.—Dorsal valves of this genus are commonly difficult to differentiate from each other, and without a ventral valve close comparison is impossible. It is the earliest known record of the genus and the family Eoconulidae .
