Description
Fossil Block Identification
This fossil block brings together three distinctive Jurassic fossil forms: Ctenostreon proboscideum bivalve, Chondroceraswrighti ammonite and a belemnite. It is an appealing multi-fossil specimen for collectors interested in Jurassic palaeontology, marine invertebrates and Dorset fossil material. The combination of bivalve, ammonite and belemnite fossils provides an excellent opportunity to display several important groups of extinct marine life within one geological specimen.
Geological Age and Location
The specimen comes from the Inferior Oolite Group of the Middle Jurassic, specifically the Bajocian and Sauzei Zone. Its stated locality is Sandford Lane Quarry, Sherborne, Dorset, UK. The Inferior Oolite Group is well known for Jurassic marine rocks and fossil-bearing deposits in southern England. During the Jurassic, this region formed part of a marine environment in which shelled invertebrates and cephalopods lived, were deposited and could ultimately become preserved in sedimentary rock.
Fossil Contents
Ctenostreon proboscideum is a fossil bivalve, representing a marine shell-bearing mollusc. Chondroceraswrighti is identified as an ammonite, a coiled marine cephalopod and one of the most recognisable fossil groups associated with the Jurassic. The block also contains a belemnite fossil, another extinct marine cephalopod. Together, these identifications make the piece especially suitable for anyone studying the diversity of Jurassic marine fossils or building a collection organised by geological period, fossil group or locality.
Collector and Display Appeal
This Jurassic fossil block offers the visual and educational interest of multiple fossil identifications in a single specimen. It can be displayed in a home collection, classroom, study, museum-style cabinet or geology-themed interior. The Dorset locality and precise stratigraphic information add useful context for collectors who value specimens with recorded geological details. It is also an engaging teaching aid for introducing the differences between bivalves, ammonites and belemnites, while demonstrating how fossils can occur together within a named geological group and biozone.
