RARE Semiovites cordevolicus Ammonite Fossil | Triassic Morocco | Genuine Specimen w/ COA

£60.00

This listing features a RARE and scientifically significant ammonite fossil: Semiovites cordevolicus, from the Triassic period, discovered in the fossil-rich outcrops of Morocco. This genus represents an early evolutionary form of ammonoid cephalopods that flourished following the Permian extinction and played a key role in Mesozoic marine ecosystems.

The specimen shown is the exact fossil you will receive, with a 1cm cube scale included in the photo for accurate sizing. As with all our fossils, it is a 100% genuine specimen, carefully selected and provided with a Certificate of Authenticity.

Geological & Scientific Information:

  • Species: Semiovites cordevolicus
  • Type: Fossil Ammonite (extinct marine cephalopod)
  • Geological Period: Triassic
  • Stage: Likely Late Triassic (Carnian–Norian) based on genus occurrence
  • Location Found: Morocco
  • Order: Ceratitida
  • Superfamily: Ceratitaceae
  • Family: Ceratitidae
  • Morphological Features: Semiovites is characterised by a compressed, discoidal shell with fine ribbing and relatively simple ceratitic suture patterns. Suture lines typically feature smooth saddles and frilled lobes. This specimen may show subtle growth lines and a coiled form that is slightly involute.
  • Depositional Environment: Shallow epicontinental marine basins with carbonate and marl sedimentation, typical of the warm, tropical Triassic seas in northern Gondwana (present-day North Africa).
  • Scientific Importance: Semiovites and related genera are important for understanding the rapid diversification of ammonoids during the Triassic recovery interval. This species is used in biostratigraphy and evolutionary studies of Ceratitida.

Additional Notes:

Ammonites from the Triassic are much rarer than their Jurassic and Cretaceous counterparts. This specimen offers an exceptional opportunity to own a piece of early Mesozoic marine history, representing a critical stage in ammonite evolution.

Triassic Information

The Triassic Period (252–201 million years ago) marked the beginning of the Mesozoic Era, following the Permian-Triassic mass extinction, the most severe extinction event in Earth's history. The climate was hot and dry, with vast deserts and little polar ice. Life slowly recovered, leading to the rise of the first dinosaurs, pterosaurs (flying reptiles), and early mammals. Reptiles, including large archosaurs (ancestors of crocodiles and dinosaurs), dominated both land and sea. In the oceans, ichthyosaurs and plesiosaurs thrived alongside ammonites and early coral reefs. The first true conifers and ginkgo trees spread across the land. The period ended with another mass extinction, paving the way for the Jurassic and the golden age of dinosaurs.
