About Cenoceras striatus:

Cenoceras is an extinct genus of nautiloid cephalopods that thrived in Jurassic seas. Unlike ammonites, nautiluses have a simpler suture pattern, reflecting their evolutionary lineage that still exists today in modern nautiluses. These ancient marine predators used jet propulsion to navigate shallow seas, hunting for small fish and invertebrates.

This well-preserved specimen from the Lower Sinemurian Stage represents an important part of Jurassic marine ecosystems, providing insight into the evolutionary history of cephalopods.
