Leptaleoceras leptum Fossil Ammonite, Upper Pliensbachian, Jurassic: Italy – 100% Genuine with Certificate of Authenticity

Description

This Leptaleoceras leptum fossil ammonite is a rare and beautiful specimen from the Upper Pliensbachian Stage of the Jurassic Period, discovered in Italy. Leptaleoceras leptum is an ammonite species known for its distinctively ribbed and evolute shell. This ammonite offers an intriguing glimpse into Jurassic marine life and is an excellent specimen for collectors and fossil enthusiasts alike. Its preservation in sedimentary rock adds to its historical value, providing an authentic piece of the Pliensbachian period.

Geological Information:

• Geological Stage: Upper Pliensbachian, Jurassic (Approximately 183 to 174 million years ago)
• Depositional Environment: During the Upper Pliensbachian, shallow marine seas covered much of the European region, including the area now known as Italy. The seas were rich in nutrients and home to a diverse range of marine life, including ammonites like Leptaleoceras leptum. The ammonite fossil was preserved in sedimentary deposits, including limestone and marl, which formed from the accumulation of marine organisms and their remains. These deposits are characteristic of the Jurassic marine environment, which was abundant in life.
• Biozone: This fossil comes from the Upper Pliensbachian biozone, a time of diverse marine life, including the wide spread of ammonites like Leptaleoceras leptum. The Pliensbachian biozone is known for its abundant ammonite species and its importance in understanding marine biodiversity during the Jurassic period.

Fossil Features:

• Family: Ammonitidae
• Super Family: Ammonoidea
• Order: Ammonitida
• Morphology: The Leptaleoceras leptum ammonite features a distinctively ribbed, evolute shell. The ammonite’s whorls are tightly coiled, showing a clear, spiraled pattern as the ammonite grew. The ribs on the shell are prominent and evenly spaced, adding texture to the fossil. The evolute shell of the ammonite reveals the earlier whorls, a key characteristic of this species.
