Somerset Ammonite Hildoceras 7cm
This lovely Somerset ammonite hildoceras is from the junction beds, inland from the jurassic coast and close to Ilminster. The Ammonite itself measures 7cm across at the widest point with fine detail and is also exceptionally well defined. This ammonite would make an ideal display piece and the ammonite is supplied with a display stand making it a wonderful addition to any collection. The South Somerset Junction Beds (now referred to as ‘The Beacon Limestone Formation’) are an extension of the fossil rich areas of Dorsets Jurassic Coast. This specimen is approximately 185 million years old, dating from the Lower Jurassic period.
Ammonites have been extinct for 65 million years. They are a form of Cephalopod, a group of marine molluscs. Ammonites were plankton feeders, with long tentacles, and swam upright. Altogether, there were in the region of four thousand different species. Ammonites became extinct 65 million years ago, at the same time as the dinosaurs. Although Ammonites themselves have long been extinct, the squid and octopus that swim in our seas now, are closely related. Ammonites range in size from 1mm wide up to metre across. They swam in the shallow tropical seas that existed in this area millions of years ago. Apart from these Jurassic Coast ammonites, see others listed under Ammonites.
