Description
Plesiosaur Jaw Fossil
This fossil is identified as a Plesiosaur Jaw from Cryptoclidus eurymerus, associated with the Oxford Clay and dating to the Callovian stage of the Jurassic. It is a compelling addition to a fossil collection, particularly for collectors interested in prehistoric marine reptiles, Jurassic palaeontology and vertebrate fossils.
Identification and Geological Context
Cryptoclidus eurymerus was a plesiosaur, a group of extinct marine reptiles that lived during the Mesozoic Era. Plesiosaurs are especially recognised in the fossil record for their distinctive body plans and aquatic adaptations. A jaw fossil offers an important connection to the feeding anatomy of these animals and provides an engaging focus for study, display and discussion.
The specimen is associated with the Oxford Clay and the Callovian, a Jurassic stage within the Middle Jurassic. The Oxford Clay is widely known for its rich fossil record and importance in the study of Jurassic marine life. This geological setting makes the identification especially appealing to collectors who value fossils with a clear connection to a significant period in Earth history.
Locality
The supplied locality information is Must Farm, Whittlesey, Peterborough. This location forms part of the specimen’s geological and collecting context and is an important detail for cataloguing, display labels and fossil collection records. The locality information can also help place the specimen within the broader study of Jurassic fossils associated with the Oxford Clay.
Collector and Display Appeal
With its identification as Cryptoclidus eurymerus, this fossil is suited to collectors of plesiosaurs, Jurassic fossils, marine reptile specimens and palaeontological history. It can be displayed as a standalone fossil or included in a themed collection covering Jurassic life, fossil vertebrates, ancient marine ecosystems or the geology of the Oxford Clay. The combination of a named plesiosaur identification, Callovian Jurassic age and stated locality gives the specimen strong educational and conversation value.
The fossil is also suitable for use alongside reference books, geological maps, educational displays and other Jurassic material. It provides an opportunity to explore how fossilised remains are used to identify extinct animals and understand life from ancient geological environments.
