This Androgynoceras maculatum ammonite fossil is a rare specimen sourced from the Denotatus Subzone of the Obtusum Zone, within the Frodingham Ironstone Formation. The fossil comes from the Lower Lias, part of the Lower Jurassic period, and was discovered in Conesby Quarry, Scunthorpe, North Lincolnshire. Known for its distinctive markings and well-preserved structure, this ammonite fossil offers a glimpse into the marine life during the Early Jurassic.

Species and Morphology Information:

• Species: Androgynoceras maculatum
• Geological Age: Lower Lias, Lower Jurassic (~199-174 million years ago)
• Depositional Environment: This ammonite was found in the Frodingham Ironstone Formation, a shallow marine environment that existed during the Lower Jurassic period. The formation is known for well-preserved ammonoids and other marine fossils.
• Morphology Features: Androgynoceras maculatum exhibits distinct spiral coiling with well-defined ribs and prominent ornamentation that characterize the ammonoid morphology of the period.
• Notable Features: This fossil ammonite is an exceptional example of ammonoid preservation, with excellent detail in the shell structure and ribbing.
• Family: Androgynoceratidae
• Superfamily: Ammonoidea
• Order: Ammonitida
• Biozone: Found in the Denotatus Subzone within the Obtusum Zone of the Lower Lias, an important biozone for ammonoid fossils from the Lower Jurassic period.
• Depositional Environment: The ammonite was deposited in shallow marine waters during the Lower Jurassic when North Lincolnshire was part of a temperate marine environment.
