About Proplanulites Fossil Ammonites:

Proplanulites is an extinct genus of ammonite that thrived during the Middle Jurassic period, approximately 164 million years ago. Ammonites were marine mollusks related to modern-day squids, octopuses, and nautiluses, thriving in prehistoric seas before their extinction.

This fossil originates from the Lower Callovian Stage, specifically from Manor Farm Pit, Oxfordshire, UK, an area known for producing high-quality ammonite specimens. Proplanulites is recognized for its large, robust shell with intricate ribbing and deep, complex suture patterns, indicative of its evolutionary adaptations in Jurassic marine environments.

Fossils like Proplanulites provide valuable insight into ancient marine ecosystems, ammonite diversity, and the evolutionary history of cephalopods. Their distinctive shell morphology and rarity make them highly desirable among collectors and researchers.

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

Description

SPECIMEN OVERVIEW

This 16-inch Proplanulites ammonite fossil is a distinctive Jurassic fossil specimen identified from the Kellaway Clay of the Lower Callovian. It comes from Manor Farm Pit, Oxfordshire, United Kingdom, and is from the Alice Purnell Collection. The specimen is presented as a substantial example for fossil collectors, Jurassic geology enthusiasts, museum-style displays and educational collections.

Proplanulites is an ammonite genus. Ammonites were extinct marine cephalopods that lived in the ancient seas and are recognised for their coiled shells. Their fossils are especially valued by collectors because ammonites are important to the study of Jurassic marine rocks and can help geologists understand the relative ages and environments of sedimentary deposits.

GEOLOGICAL INFORMATION

The specimen is identified as Lower Callovian in age, within the Jurassic Period. The Callovian is a stage of the Middle Jurassic, and the Lower Callovian represents its earlier part. The Kellaway Clay is associated with Jurassic sedimentation in England and provides an important geological context for fossils discovered in Oxfordshire and surrounding areas.

A fossil locality such as Manor Farm Pit adds useful geological context to a specimen, linking it to the rocks and sediments in which it was found. Oxfordshire has long been recognised as an important area for Jurassic geology, making this Proplanulites ammonite an appealing addition to collections focused on British fossils, Jurassic stratigraphy and regional palaeontology.

COLLECTOR AND DISPLAY APPEAL

With its Proplanulites identification, Lower Callovian age and Kellaway Clay locality, this fossil offers several points of interest for collectors. It can be used as a conversation piece in a home collection, incorporated into a geology display or studied alongside other Jurassic ammonites and fossils from the United Kingdom. The specimen also provides an accessible way to explore the relationship between fossil identification, geological age and the sedimentary rocks of a particular locality.

The 16-inch scale makes this an eye-catching fossil for display. Full sizing is shown in the photographs. Please review the photographs carefully for the overall appearance and presentation of the specimen before purchase.
