About Proplanulites Ammonite Fossils:

Proplanulites is an extinct genus of ammonites from the Middle Jurassic period, approximately 166-164 million years ago. These ammonites belonged to an extinct group of marine cephalopods related to modern-day squids, octopuses, and nautiluses.

This species is known for its large size, involute shell, and finely ribbed ornamentation, making it a distinctive and highly recognizable ammonite. Fossils of Proplanulites are found in marine sedimentary deposits, particularly in Ashton Keynes, United Kingdom, a site well-known for its exceptional fossil preservation.

Ammonites like Proplanulites played a crucial role in prehistoric marine ecosystems and are important index fossils used by paleontologists to date rock layers. Their intricate shell patterns and evolutionary significance make them highly sought-after by collectors and researchers.

Perfect for display, educational purposes, or as a unique gift for fossil lovers and paleontology enthusiasts, this ammonite is a one-of-a-kind addition to any fossil collection.

Description

Overview

This rare 15-inch Proplanulites ammonite fossil is identified as Middle Callovian, Jurassic. It is a striking natural-history display piece for fossil collectors, Jurassic geology enthusiasts, museum-style interiors and anyone interested in the ancient marine life recorded in the fossil record. The substantial format gives the specimen a strong visual presence while retaining the scientific and educational appeal associated with ammonite fossils.

Identification and Geological Context

Proplanulites is an ammonite identification, placing this fossil within an extinct group of marine cephalopods that lived in the seas of the Mesozoic Era. Ammonites are especially valued by collectors because their coiled shells preserve recognisable forms and provide an accessible connection to Jurassic palaeontology. The specimen is identified as Middle Callovian, Jurassic, linking it to a specific interval within the Jurassic Period rather than to a broad, general geological age.

The Callovian forms part of the Middle Jurassic. Ammonites from this interval are of interest not only as display fossils but also as geological markers, because their evolutionary changes and distribution have helped palaeontologists compare and date marine rock sequences. A Proplanulites specimen therefore offers both decorative appeal and a direct focus for learning about Jurassic marine environments, ammonite evolution and the use of fossils in stratigraphy.

Collection and Display

From the Alice Purnell Collection

The 15-inch presentation makes this fossil suitable for a dedicated fossil cabinet, study, office, library, classroom or geology-themed display. Its size allows the ammonite form to be appreciated from across a room, while closer viewing reveals the natural character that makes each fossil specimen individual. It can be displayed as a standalone Jurassic feature or incorporated into a wider collection of ammonites, fossils and geological specimens.
