This is a very rare and well-preserved Nautilus jourdani fossil, dating back to the Toarcian stage of the Early Jurassic (~183 million years ago), discovered in Floore, Northamptonshire, United Kingdom.

Nautilus jourdani is an extinct species of nautiloid cephalopod, closely related to modern-day nautiluses. Unlike ammonites, nautiloids have smooth, coiled shells with internal chambers that allowed them to regulate buoyancy. These prehistoric marine predators roamed the Jurassic seas, preying on small fish and crustaceans.

Fossils of Nautilus jourdani are extremely rare, making this specimen a significant addition to any fossil collection or museum display. It represents a crucial part of cephalopod evolution, showcasing the lineage that has survived over 500 million years.
