Oistoceras Fossil Ammonite Green Ammonite Beds Lower Lias Jurassic Coast UK

Description

Oistoceras Fossil Ammonite

This fossil ammonite is identified as Oistoceras and is associated with the Green Ammonite Beds of the Lower Lias on the Jurassic Coast. Its recorded location is Stonebarrow Cliff, Charmouth, Lyme Regis, Dorset, UK, a well-known coastal area with important exposures of Jurassic rocks and fossils.

Geological Setting

The Lower Lias forms part of the Lower Jurassic succession and is widely recognised for its fossil-rich marine rocks. Along the Dorset coast, changing sea levels, sediment accumulation and coastal erosion have exposed layers containing a diverse record of Jurassic life. The Green Ammonite Beds are part of this geological setting and provide an important context for ammonite collecting and study.

Ammonite Identification

Oistoceras is an ammonite fossil name associated with Jurassic marine deposits. Ammonites were extinct marine cephalopods related, in a broad living sense, to modern squid, cuttlefish and nautiluses. Their commonly coiled shells made them especially valuable to palaeontologists because changes in shell form through geological time can help with the study and comparison of rock layers.

Ammonites are also important index fossils. Their relatively rapid evolutionary changes and broad distribution allowed particular forms to be used in biostratigraphy, helping researchers correlate sedimentary rocks from different locations. A named Oistoceras specimen therefore offers both visual collector interest and a connection to the study of Jurassic marine environments.

Collector Display and Study

This Oistoceras fossil ammonite is suited to fossil collections, geology displays, educational use and anyone interested in the Jurassic Coast. The documented association with the Green Ammonite Beds and the Lower Lias adds useful geological context for collectors who value locality information alongside the fossil itself. Stonebarrow Cliff and the Charmouth area are part of the celebrated Lyme Regis section of the Dorset coast, where Jurassic strata have contributed significantly to the understanding of marine fossil assemblages.

The fossil can be displayed as a natural-history specimen representing Jurassic marine life and the long geological history preserved in the rocks of southern England. It may also be used as a conversation piece when discussing ammonite evolution, fossil formation, stratigraphy and the relationship between geological layers and palaeontological identification.
