Rare Baculites Fossil Ammonite Eubaculites Otacodensis Coniacian Cretaceous

Original price was: £60.00.Current price is: £48.00.

This is a rare Eubaculites otacodensis ammonite fossil from the Coniacian stage of the Late Cretaceous period (~89-86 million years ago), discovered in Tulear, Madagascar. Eubaculites is a genus of straight-shelled ammonites, a now-extinct group of marine cephalopods related to modern squid and cuttlefish. Unlike their coiled relatives, Eubaculites had an elongated, uncoiled shell, offering a unique adaptation for buoyancy control in marine environments.

Fossils from Tulear, Madagascar, are known for their exceptional preservation, and this Baculites specimen provides valuable insight into Cretaceous marine ecosystems. It is a highly collectible piece for both fossil enthusiasts and scientific study.

Description

Fossil Identification

This listing presents a rare Baculites fossil ammonite identified as Eubaculites otacodensis. The specimen is associated with the Coniacian stage of the Cretaceous Period, placing it within an important interval of Earth’s geological history. Baculites were extinct marine cephalopods belonging to the ammonite group, known for their distinctive straight or gently curved shell forms compared with the tightly coiled shells commonly associated with ammonites.

Eubaculites otacodensis is a specialist fossil identification that will appeal to collectors who value named ammonite taxa, Cretaceous palaeontology and unusual heteromorph ammonite forms. The combination of the genus, species identification and Coniacian age makes this an engaging addition to a fossil collection, geological display or educational cabinet.

Locality and Collection History

The specimen is listed from Tulear, Madagascar. Madagascar is internationally recognised for its rich and varied fossil record, making material associated with the region especially interesting to collectors of palaeontology and natural history. This piece is from the Alice Purnell Collection, adding a named collection connection for enthusiasts who appreciate the history and documented identity of individual specimens.

The Coniacian is a stage within the Upper Cretaceous. During the Cretaceous, ammonites were widespread marine organisms and their shells can provide valuable information for understanding ancient seas, fossil succession and geological time. Baculites are particularly notable because their unusual shell shape demonstrates the diverse evolutionary forms developed by ammonites.

Collector Appeal

This Eubaculites otacodensis fossil is suited to collectors of Baculites, ammonites, Cretaceous fossils, Madagascar specimens and named cephalopod fossils. It can be displayed as a standalone geological specimen or included in a broader collection arranged by fossil group, geological period, locality or ammonite evolution. Its Coniacian identification provides a clear educational focus for discussions of Cretaceous marine life and the changing forms of extinct cephalopods.

The piece may also be suitable for classroom, museum-style or home display, where fossil identification labels can help explain the relationship between ammonites, extinct marine molluscs and geological time. Collectors interested in taxonomy will appreciate the specific identification of Eubaculites otacodensis rather than a general ammonite designation.
