Description

This listing features a RARE and authentic Triassic ammonite fossil of the species Wyominglites aplanatum, discovered in the Thaynes Limestone formation of Elko County, Northeastern Nevada, USA. An exceptional piece from the early Mesozoic marine ecosystem, showcasing a key representative of Lower Triassic ammonoid recovery fauna.

Fossil Type & Species:

• Type: Fossilised Ammonite (extinct marine cephalopod)
• Species: Wyominglites aplanatum

Geological Context:

• Era: Mesozoic
• Period: Triassic
• Stage: Lower Triassic (Spathian)
• Formation: Thaynes Limestone
• Locality: Elko County, Nevada, USA
• Depositional Environment: Shallow marine shelf, characterized by carbonate sedimentation within a post-extinction epicontinental sea
