A Jurassic Coast information site. By Christopher M. PamplinB.Sc.(hons.)
A collection of Ammonite specimens from the Lower Jurassic of Dorset and Somerset, South West England. Dorset's Jurassic Coast, Lyme Regis, Charmouth, and inland sites.
The World Heritage Coast of Devon & Dorset.

The following gallery pages are intended to provide a reference for the more serious collector of ammonite fossils. The ammonites are grouped systematically to assist in recognition of morphological features.
 
There are many species of ammonite fossil which have been identified from the Jurassic and Cretaceous periods of Earth history. To cover all would be a mammoth task indeed. This collection is based on my own fossils and those which my friends who live on the Dorset Coast have collected. It is therefore far from a complete record of species, but reflects those ammonites which can be found with a little luck along the Dorset Coast and at a few inland and coastal sites of Somerset. It concentrates therefore on Jurassic ammonites, particularly on those of the Lower Jurassic. It is envisaged that the collection will grow as new specimens are photographed and added to the site. I hope you enjoy your visit.
