 ... from the English Chalk by Jefferies (1962, I963) who briefly described and illustrated a " problematicum " from the top of the Lower Chalk and the plenus Marls Subsequent collecting shows that they are common throughout the whole of the Lower Chalk, and also occur in the Melbourn Rock at the base of the Middle Chalk Specimens show great shape variation in both outline, thickness and convexity, but form a quite distinctive group of trace fossils In thin section, the constituents are clearly the coarse fraction of the chalk Foraminifera are abundant, ostracods, shell and echinoid debris plus small masses of collophane (? faecal pellets) make up the rem
