Description
This is a rare Pseudolillia emiliana fossil ammonite with an associated belemnite, dating to the Lower Aalenian stage of the Middle Jurassic (~174-170 million years ago), discovered in Rhône, France. Pseudolillia belongs to the Hammatoceratidae family and is characterized by its moderately involute shell, fine ribbing, and well-defined whorls, typical of ammonites from this period.
What makes this fossil particularly unique is the presence of an associated belemnite, an extinct relative of modern squid. Belemnites were marine cephalopods with internal shells, and their fossils are often found in the same deposits as ammonites, indicating they shared the same ancient marine environment.
Fossils from the Aalenian stage are less common than those from other Jurassic stages, making this specimen a valuable piece for collectors and researchers alike. It provides an incredible glimpse into Middle Jurassic marine ecosystems.
