Cobcrephora is a genus of molluscs that resembles the Palaeoloricata, known from the Silurian of Gotland. Its interpretation as a polyplacophoran is widely challenged.
Its mollusc shell is unique, because Cobcrephora was described on the basis of isolated phosphatic sclerites.Bischoff, G. C. O. 1981. Cobcrephora n. g., representative of a new Polyplacophoran order phosphatoloricata, with calciumphosphatic shells. Senckenbergiana Lethaea, 61:173-215 Its overlapping sclerites are arched and small, comprising two shell layers, and have lamellar projections.
