RARE Triassic Ammonite Fossil – CERATITES NEVADENSIS – Middle Triassic – USA
£18.00
This listing showcases a RARE and authentic Triassic ammonite fossil of the species Ceratites nevadensis, originating from the Middle Triassic strata of the western United States. This distinctive fossil is a prime example of ceratitid ammonoids, an important evolutionary group of cephalopods from the Triassic period.
Fossil Type & Species:
- Type: Fossilised Ammonite (extinct marine mollusc)
- Species: Ceratites nevadensis
Geological Context:
- Era: Mesozoic
- Period: Triassic
- Stage: Likely Anisian or Ladinian (Middle Triassic)
- Locality: USA (precise locality data limited; Nevada region likely based on species name)
- Depositional Environment: Shallow marine shelf, typically carbonate-rich environments with episodic influxes of siliciclastics
Morphological Features:
- Evolute shell structure with broad whorls and a low keel
- Characteristic ceratitic suture lines with rounded lobes and saddles
- Medium to large size ammonite with finely ribbed shell surface
Scientific Notes:
- Ceratites nevadensis is an important ammonoid species used in biostratigraphic correlation of Middle Triassic marine sequences in the western USA.
- The genus Ceratites is renowned for its transitional suture patterns, bridging earlier goniatites and later ammonites.
- This fossil reflects marine evolutionary recovery and radiation following the end-Permian mass extinction.
Taxonomy:
- Order: Ceratitida
- Superfamily: Ceratitoidea
- Family: Ceratitidae
- Formally Described By: Commonly referenced in regional Middle Triassic ammonoid faunal studies; detailed taxonomic authority may vary depending on reference
Authenticity & Display:
All of our fossils are 100% Genuine Specimens and come with a Certificate of Authenticity. The fossil shown in the photograph is the exact piece you will receive.
Please refer to the image for exact sizing – Scale cube = 1cm.
An exceptional piece for collectors and enthusiasts of Mesozoic marine life, Triassic ammonoids, or key evolutionary transitions within cephalopods.
