Geology and Fossil Type

• Geological Stage: Maastrichtian, Late Cretaceous
• Depositional Environment: Marine (The Pierre Shales and Fox Hills Sandstone were marine environments during the Maastrichtian period, making them perfect for the preservation of ammonites like Hoploscaphites landesi. This fossil was found in the marine deposits of South Dakota.)
• Family: Scaphitidae (The Hoploscaphites landesi species belongs to the Scaphitidae family, a group of ammonites known for their irregular, heteromorphic coiling.)
• Superfamily: Ammonoidea
• Order: Ammonitida (This species belongs to the Cephalopoda class, a group related to modern squid, octopuses, and cuttlefish.)

Morphology Features

The Hoploscaphites landesi ammonite is a heteromorphic ammonite, which means its shape deviates from the typical coiling pattern of other ammonites. It exhibits a distinct, irregular coiling, giving it a knobby appearance. The unusual, asymmetric corkscrew shape sets it apart from more common ammonites. Its surface is well-preserved, with visible suture lines and a textured surface that provide detailed information about the ammonite’s structure.
