This specimen offers excellent preservation of morphological features and represents a key taxon in Middle Jurassic ammonite biostratigraphy.

  • Fossil Type: Ammonite (extinct marine cephalopod)
  • Species: Proplanulites koenigi
  • Size: See image with 1cm scale cube for sizing
  • Geological Period: Jurassic
  • Stage: Lower Callovian (~166–164 million years ago)

Geological & Scientific Significance:

Proplanulites koenigi is a distinctive ammonite species that typically marks the Macrocephalites gracilis Zone of the Lower Callovian. These ammonites are known for their planispiral, compressed shells with relatively smooth flanks and subtle ribbing. Their suture lines and evolute coiling pattern make them ideal for both collectors and biostratigraphic studies.

The Manor Farm site in Wiltshire is part of the wider Oxford Clay basin, an exceptionally rich fossil-bearing formation spanning much of southern England. This marine clay formation preserves a wide variety of ammonites, bivalves, belemnites, and marine reptiles, offering insight into a dynamic Jurassic sea.

Notable Features:

  • Clean, compressed planispiral shell structure
  • Light ribbing with strong suture definition
  • Well-documented zonal index fossil for the Lower Callovian
  • From a classic fossil locality in southern England

Authenticity Guaranteed: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity, ensuring full traceability and scientific accuracy.

Photo Disclosure: You will receive the exact specimen pictured. Scale cube shown in the photo is 1cm per square for reference.

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.
