Fossil Belemnite Cylindroteuthis Puzosiana Oxfordian Jurassic Bedfordshire UK | Alice Purnell Collection

Original price was: £12.00.Current price is: £9.60.

This is a genuine Cylindroteuthis puzosiana belemnite fossil from the Oxfordian stage of the Jurassic period, discovered in Bedfordshire, United Kingdom. Belemnites were an extinct group of marine cephalopods related to modern squid and cuttlefish. Unlike ammonites, they possessed an internal shell known as a guard, which fossilised over millions of years and is a common feature of Jurassic marine deposits.

Geological Context

This specimen originates from the Oxford Clay Formation, a well-documented marine deposit from the Oxfordian stage (Late Jurassic, approximately 157-163 million years ago). The Oxford Clay is rich in fossils, including ammonites, marine reptiles, and belemnites, which thrived in the shallow seas that covered what is now southern England during the Jurassic period. The fine-grained, organic-rich sedimentary rock of this formation provides excellent conditions for fossil preservation.

Fossil Type & Species Information

Belemnites, like Cylindroteuthis puzosiana, were marine predators with a torpedo-shaped body and a hard, internal rostrum (guard) that provided stability in the water. Unlike ammonites, belemnites lacked an external shell and had ten arms lined with small hooks for catching prey. They are thought to have played a vital role in the Jurassic marine food chain, serving as prey for large marine reptiles such as ichthyosaurs and pliosaurs.

Cylindroteuthis puzosiana is characterized by:

  • A robust, elongated guard with a smooth surface
  • A distinctive bullet-like shape tapering to a point
  • Calcitic composition, replacing the original aragonite structure over time

Key Features:

  • Authentic Cylindroteuthis puzosiana fossil belemnite
  • Age: Approximately 157-163 million years old (Oxfordian, Jurassic)
  • Geological Formation: Oxford Clay Formation
  • Origin: Bedfordshire, United Kingdom
  • Distinctive bullet-shaped guard with well-preserved surface details

Description

Fossil Belemnite Identification

This collectible fossil is identified as Cylindroteuthis puzosiana, a belemnite associated with the Oxfordian stage of the Jurassic. The specimen is from Bedfordshire, United Kingdom, and forms part of the Alice Purnell Collection. Its scientific identification and geological context make it an appealing addition to collections focused on fossils, Jurassic life, marine palaeontology and historical natural specimens.

Belemnite Fossil Context

Belemnites were extinct marine cephalopods related to modern squid and cuttlefish. They lived in the oceans during the Mesozoic Era, including the Jurassic Period. Unlike modern cephalopods, belemnites are commonly represented in the fossil record by the solid internal part of the shell, especially the robust rear section known as the rostrum. These fossils are frequently collected because they provide a tangible record of ancient marine ecosystems and the animals that inhabited them.

The Oxfordian is a stage within the Jurassic Period. Presenting the stage alongside the identification connects this specimen with a defined interval of geological time and gives it added interest for collectors who organise fossils by geological age, palaeontology enthusiasts studying Jurassic marine life, and educational displays exploring Earth history.

Collection and Display Appeal

With its named identification, Oxfordian Jurassic context and Bedfordshire location, this belemnite is suited to a fossil cabinet, geology display, educational collection or gift for a palaeontology enthusiast. The specimen can be appreciated as both a natural historical object and an example of the fossil record associated with extinct marine cephalopods. Its inclusion in the Alice Purnell Collection adds a specific collection association for buyers who value named or documented fossil pieces.

The fossil may be displayed alongside other Jurassic specimens, belemnites or marine fossils to create a themed geological arrangement. It is also suitable for collectors interested in the relationship between fossil identification, geological stages and the preservation of ancient life.
