Very Rare 9in Asteroceras Sectioned Polished Fossil Ammonite Lower Jurassic

Description

Fossil Identification

This very rare specimen is identified as Asteroceras, a fossil ammonite presented in a sectioned and polished form. Its 9-inch presentation makes it an impressive addition to a serious fossil collection, geological display or natural history cabinet. The polished section offers a distinctive view of the fossilised ammonite structure, combining scientific interest with the visual appeal of a prepared collector specimen.

Ammonites were extinct marine cephalopods with coiled shells, and their fossils are highly valued for their importance in geological study and stratigraphic comparison. Asteroceras is associated with the Lower Jurassic and represents an important ammonite form from this period. The sectioned and polished finish allows the internal form of the fossil to be appreciated more clearly than on an unprepared example, while retaining the character of the original fossil material.

Geological Context

This specimen is recorded from the Frodingham Ironstone Formation, within the Denotatus Subzone and Obtusum Zone of the Lower Lias, Lower Jurassic. These stratigraphic details are especially valuable to collectors because they place the fossil within a defined geological sequence rather than identifying it only by its general appearance.

The Lower Lias is a recognised Lower Jurassic geological interval, and ammonites from this part of the succession are of particular interest for understanding the fossil record and relative dating of Jurassic rocks. The formation, zone and subzone information supplied with this specimen make it suitable for collectors who appreciate both the aesthetic and scientific aspects of palaeontology.

Locality and Collection

The locality is Conesby Quarry, Scunthorpe, North Lincolnshire, England. The specimen is from a named geological setting and is offered as a substantial prepared fossil ammonite for display and study.

Sectioned and Polished Finish

The specimen has been sectioned and polished to enhance its presentation and reveal the fossil form across the prepared surface. This type of preparation is popular with collectors because it creates a clear, display-ready surface while highlighting the internal arrangement and natural patterning associated with the fossilised ammonite. It can be displayed as a focal piece in a fossil collection, geological study area, office, library or natural history interior.

Sizing Information

Full sizing is shown in the photographs. Please use the photographs as the reference for the specimen’s complete scale and presentation. The 9-inch designation forms part of the supplied product identification, while the detailed images provide the clearest view of the actual piece available.

Collector Appeal

This Asteroceras ammonite combines a named fossil identification, a documented Lower Jurassic geological context and an attractive sectioned and polished finish. Its association with the Frodingham Ironstone Formation, Denotatus Subzone and Obtusum Zone gives it strong appeal for ammonite collectors, Jurassic fossil enthusiasts, geology students, museum-style displays and anyone interested in scientifically contextualised natural history specimens. The connection with Conesby Quarry and the Alice Purnell Collection adds further interest to its presentation as a collected and prepared fossil.
