Kepplerites keppleri Ammonite Fossil | Lower Callovian, Jurassic | Oxfordshire UK | Alice Purnell Collection | Genuine with Certificate

Description

Fossil Type & Species:

This listing features a genuine ammonite fossil of Kepplerites keppleri, a classic ammonite species from the Lower Callovian Stage of the Jurassic Period. Discovered in Oxfordshire, United Kingdom, this well-preserved specimen comes from the reputable Alice Purnell Collection, offering both scientific interest and excellent provenance.

Geological Formation & Insight:

Kepplerites is a genus of ammonite in the family Kosmoceratidae, well-known for its strongly ribbed, involute shell and distinctive suture lines. These ammonites were fast-swimming, nektonic cephalopods that lived in open marine environments and are important biostratigraphic markers for the Middle Jurassic.

This fossil comes from rocks of the Lower Callovian Stage (Middle Jurassic), approximately 166 to 163 million years ago, within the classic Jurassic marine sequences of southern and central England, particularly well exposed in Oxfordshire. The region was once submerged beneath a warm, shallow sea connected to the Tethys Ocean — a rich marine ecosystem teeming with ammonites, belemnites, marine reptiles, and bivalves.

Fossils from this locality often show excellent detail due to the fine-grained limestone and clay matrix that preserves shell morphology, ribbing, and even suture lines in remarkable condition.
