JURASSIC NAUTILUS
180 million years old
Ilminster, Somerset
A good example of a nautilus from the Middle Lias 'Junction Bed' (Beacon Limestone) near Ilminster.
The Lias rocks of the Ilminster area are unusual in that they take the form of a highly condensed sequence with several ammonite zones reduced to only a few metres in thickness and sometimes packed with fossils.
The nautilus is related to ammonites, but unlike ammonites it did not become extinct.
This fossil is incomplete on one side and one small section has been restored with plaster (see photo). However, it is still a good example.
