Buntings Lane Pit, Peterborough

Cornbrash is an old agricultural name applied to a variety of stone rubble or brash which forms a good soil for growing corn. It is now a formal geological formation.

The pit at Bunting’s Lane was a borrow pit for the Peterborough by-pass. It provided a section from the top of the Cornbrash, through the Kellaways Formation into the Lower Oxford Clay.

These fossils were collected in 1985.
