TRILACINOCERAS hunanense Fossil Nautilus – Middle Ordovician – Hunan, China

£36.00

This listing features an authentic and scientifically significant Fossil Nautilus of the species Trilacinoceras hunanense, originating from the Middle Ordovician rocks of Hunan Province, China. Trilacinoceras represents a genus of extinct nautiloid cephalopods that thrived in ancient marine environments more than 460 million years ago.

Fossil Type & Species:

  • Type: Fossilised Nautiloid (Cephalopod)
  • Genus: Trilacinoceras
  • Species: Trilacinoceras hunanense

Geological Context:

  • Era: Paleozoic
  • Period: Ordovician
  • Stage: Middle Ordovician (likely Darriwilian)
  • Locality: Songtao, Hunan Province, China
  • Depositional Environment: Marine shelf environments with well-oxygenated waters and rich benthic fauna, conducive to the preservation of hard-shelled organisms

  • Chambered shell with prominent siphuncle structure
  • Subtle transverse growth lines and fine shell ornamentation
  • Well-defined septa separating internal chambers

Scientific Notes:

  • Nautiloids like Trilacinoceras were important early cephalopods, playing a crucial role in the Ordovician marine ecosystem
  • Their fossils provide key insights into the evolution of cephalopods and the diversification of marine life during the Great Ordovician Biodiversification Event
  • Formally described in Chinese paleontological literature, contributing to the regional biostratigraphy of the Ordovician system

Taxonomy:

  • Order: Orthocerida
  • Superfamily: Orthocerataceae
