What’s the difference?

A nautilus differ from an ammonite in that its internal chamber walls are simple and saucer-shaped. In comparison, an ammonite’s chamber walls are complex and create delicate, folded suture lines (see photo on right). Like the nautilus, many ammonites grow in such a way that the outer whorls enclose the inner ones but the same fundamental difference always applies.

This nautilus was collected and given to Bridport Museum by Barney Hansford. He was a local Charmouth collector from the 1950s through to the 1970s. He built up a large collection of local fossils and displayed them in Barney’s Fossil Exhibition in Charmouth. After his death, the collection was broken up but some specimens found their way to Bridport Museum’s collection.
