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.
