Geology and Fossil Type

• Geological Stage: Maastrichtian, Late Cretaceous
• Depositional Environment: Marine (The Pierre Shales and Fox Hills Sandstone formations were marine environments during the Maastrichtian period, ideal for the formation of ammonites like Jeletzkytes. This fossil was preserved in the marine deposits of South Dakota.)
• Family: Scaphitidae (The Jeletzkytes species belongs to the Scaphitidae family, a group of ammonites known for their distinct coiling and heteromorphic features.)
• Superfamily: Ammonoidea
• Order: Ammonitida (As with all ammonites, Jeletzkytes belongs to the Cephalopoda class, closely related to modern squid, cuttlefish, and octopuses.)

Morphology Features

The Jeletzkytes ammonite is a heteromorphic ammonite, which is known for its irregular coiling. The knobby appearance and unique corkscrew-like shape are key features of the Jeletzkytes genus. This particular specimen is particularly rare due to its iridescent sheen, which adds visual appeal and uniqueness. The ribbing and suture lines are visible, providing important details about the fossil’s structure and morphology.
