This fossil is found in early to late Cretaceous rocks - notably the chalk of England, northern Europe, Russia, Italy and Brazil. It lived in deep seas over 120 million years ago.
This is a very common fossil in the chalk of southern England. It can be found in sea cliff exposures and as a flint pebble on the beach. Chalk cliffs are resistant to erosion and are less likely to be threatened by coastal defence.
Fossil collecting should only be carried-out with the permission of the land owner.
Great care should be taken when fossil collecting - check tide times and always be aware of the danger of rock falls. It is always best to go as part of an organised group.
