RARE Fossil Ammonite Caloceras blumenbachii Hettangian Jurassic Redcar UK | Authentic Specimen

£24.00

This listing features a rare and historically significant fossil specimen of Caloceras blumenbachii, a classic Lower Jurassic ammonite from the famous Redcar site in Yorkshire, United Kingdom. Commonly referred to as the “Sun Ammonite” due to its radiant rib pattern, this species is an iconic fossil and a signature index fossil of the Hettangian Stage.

Geological & Taxonomic Information:

  • Fossil Type: Ammonite (extinct marine cephalopod)
  • Species: Caloceras blumenbachii (named after Johann Friedrich Blumenbach)
  • Order: Ammonitida
  • Superfamily: Psiloceratoidea
  • Family: Psiloceratidae
  • Geological Stage: Hettangian (Early Jurassic)
  • Age: Approximately 201.3 – 199.3 million years ago
  • Location: Redcar, Yorkshire, England
  • Formation: Lower Lias
  • Depositional Environment: Shallow marine shelf, predominantly mudstone and shale deposition with occasional limestone beds

Stratigraphic Significance: Caloceras blumenbachii is a zonal ammonite that marks the base of the Jurassic system and is frequently used in biostratigraphy to identify the beginning of the Hettangian worldwide. Its presence signifies the recovery of marine life after the end-Triassic extinction event.

Morphological Features:

  • Distinctive broad and flat spiral shell
  • Radiating, coarse ribbing extending to the umbilicus
  • Evolute coiling with visible inner whorls
  • Typical of the genus, showing strong ornamentation and good suture line detail

Notable Information: This ammonite is especially valuable to collectors for both its aesthetic qualities and geological importance. The “Sun Ammonite” from Redcar is emblematic in UK palaeontology and is frequently featured in British fossil literature.

Specimen Information:

  • Fossil Origin: Redcar, Yorkshire, UK
  • Scale: Scale rule squares/cube = 1cm. Please refer to the photo for full sizing.
  • Condition: Carefully selected specimen with excellent preservation

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.
