Rare Iridescent Baculites Fossil Ammonite Eubaculites Otacodensis Maastrichtian: Canada

Original price was: £132.00.Current price is: £105.60.

This is a rare and beautifully iridescent Eubaculites otacodensis ammonite fossil, dating back to the Maastrichtian stage of the Late Cretaceous period (~72-66 million years ago), discovered in Canada. Eubaculites is a genus of straight-shelled ammonites, an extinct group of marine cephalopods closely related to modern squid and cuttlefish. Unlike their coiled relatives, Eubaculites developed a long, uncoiled shell, which provided unique buoyancy adaptations for open marine environments.

What makes this specimen truly special is its stunning natural iridescence, caused by the preservation of the original nacreous shell layers, reflecting vibrant colors under light. This rare ammonite fossil is highly sought after for both its scientific importance and aesthetic appeal.

Description

Fossil Identification

This rare iridescent Baculites fossil ammonite is identified as Eubaculites otacodensis. It is listed as Maastrichtian and Cretaceous, placing it within the late Cretaceous fossil record. Baculites are distinctive straight-shelled ammonites, a group of extinct marine cephalopods related to other chambered ammonites. Their streamlined, uncoiled shells make them especially recognisable and highly appealing to fossil collectors, natural history enthusiasts and anyone interested in prehistoric marine life.

The specimen is presented as a genuine fossil example of Eubaculites otacodensis, with an iridescent appearance that gives the shell a visually striking display quality. The combination of the Baculites form, named identification and Maastrichtian Cretaceous age makes this an engaging addition to a fossil collection, educational display, cabinet of curiosities or geology-themed interior.

Geological Interest

The Maastrichtian represents the final stage of the Cretaceous Period. Fossils from this interval are particularly significant because they document marine life shortly before the end-Cretaceous extinction event. Baculites fossils are valued for their characteristic shell form and for the insight they provide into the diversity of ammonites that inhabited ancient marine environments during the Cretaceous.

Eubaculites otacodensis offers a named fossil identification rather than a generic ammonite description, making it suitable for collectors who appreciate taxonomic detail. The straight shell of Baculites also provides a useful contrast with the tightly coiled forms commonly associated with ammonites, making this type of fossil a strong educational example for displays focused on cephalopod evolution and prehistoric oceans.

Collection and Display

This specimen is from the Alice Purnell Collection. Its iridescent presentation makes it suitable for display in a fossil cabinet, study, office, classroom or home collection. It can be paired with other Cretaceous fossils, ammonites, marine fossils or examples of extinct cephalopods to create a broader geological and palaeontological display.

The specimen is associated with Canada as supplied in the product information. Full sizing is shown in the photographs. The photographic presentation is intended to show the actual item available for purchase, allowing collectors to assess its visible character and display appeal before ordering.
