Orthocones

Orthocones show a similar morphology to the modern Pearly Nautilus except that the shell is straight. This is a piece of Orthoceras bulatum.

This is one of the common silurian fossils found in the Ludlow area. It is usually found as fragments of a much larger shell which in some cases extended to over a metre in length.

Common finds are also the septa which separated the chambers of the shell. These are from Leurocycloceras whitcliffense.

Sometimes the almost complete remains of smaller species can be found.

I believe this to be Orthoceras dimidiatum but lack of detail makes positive identification difficult.
