Orthosphinctes tiziani Fossil Ammonite – Middle Callovian Jurassic – Bulgaria – Genuine Fossil with Certificate

£18.00

This listing is for a beautifully preserved Orthosphinctes tiziani fossil ammonite from the Middle Callovian Stage of the Jurassic Period, discovered in Bulgaria. With its intricate ribbing and distinctive spiral, this ammonite specimen is an excellent representation of mid-Jurassic marine life. The photo shows the exact fossil you will receive, and the scale cube = 1cm gives a clear size reference. Please examine the photo carefully for exact measurements.

Species & Classification:

  • Genus & Species: Orthosphinctes tiziani
  • Type: Fossil Ammonite (Extinct Marine Cephalopod)
  • Order: Ammonitida
  • Superfamily: Perisphinctoidea
  • Family: Aspidoceratidae
  • Phylum: Mollusca
  • Class: Cephalopoda

Geological & Stratigraphic Context:

  • Geological Period: Jurassic
  • Stage: Middle Callovian (~165 million years ago)
  • Zone (if applicable): Possibly Athleta or Erymnoceras Biozones, though precise locality would determine this
  • Locality: Bulgaria (exact site may influence zonation)
  • Depositional Environment: Shallow epicontinental marine environment, typical of Tethyan realm carbonate platforms during the Jurassic

Morphological Features:

  • Moderately involute shell with a wide umbilicus
  • Prominent, bifurcating ribs crossing the flanks with regular spacing
  • Smooth venter (outer edge), characteristic of Orthosphinctes genus
  • Sutures are moderately complex and diagnostic of Aspidoceratid lineages

Notable Information:

  • Orthosphinctes tiziani is a well-established marker ammonite for the Middle Callovian and helps correlate strata across Europe
  • The genus is part of the rich Perisphinctoid radiation of ammonites during the Jurassic
  • Ammonites like these are often used for relative dating of marine sediments and palaeoenvironmental reconstructions

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
