Pleuroceras spinatum Ammonite Fossil – Lower Bajocian Stage, Middle Jurassic, Palencia, Spain

This beautifully preserved fossil is an authentic specimen of Pleuroceras spinatum, a fast-moving nektonic ammonite that lived during the Lower Bajocian stage of the Middle Jurassic, approximately 170 to 168 million years ago. Recovered from the marine deposits of Palencia, Spain, this ammonite features striking ribbing and a pronounced keel, making it highly desirable for collectors and educators alike.

Fossil Type & Species:

  • Type: Invertebrate Fossil (Ammonite Shell)
  • Species: Pleuroceras spinatum
  • Order: Ammonitida
  • Superfamily: Eoderoceratoidea
  • Family: Pleuroceratidae
  • Described by: Bruguière, 1789

Geological & Stratigraphic Details:

  • Location: Palencia Province, Castile and León, Spain
  • Formation: Bajocian marine limestone and marl beds
  • Geological Stage: Lower Bajocian (Middle Jurassic)
  • Age: ~170–168 million years ago
  • Biozone: Spinatum Biozone (named for this species)
  • Depositional Environment: Shallow marine shelf with carbonate-rich sedimentation ideal for fossil preservation

Morphology & Features: This Pleuroceras spinatum ammonite shows:

  • Planispiral coiling with a flat to moderately convex venter

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.
