RARE 8.5″ Ludwigia murchisoni Fossil Ammonite – Middle Bajocian, Jurassic – Horn Park Dorset UK – COA – Alice Purnell Collection

Original price was: £180.00.Current price is: £162.00.

Presenting a striking and rare 8.5-inch specimen of Ludwigia murchisoni, a beautiful fossil ammonite from the Middle Bajocian Stage of the Jurassic Period, collected from the classic fossil locality of Horn Park, Dorset, United Kingdom. This fossil comes from the scientifically respected Alice Purnell Collection, and the exact specimen is shown in the photo.

Geological Context:

  • Species: Ludwigia murchisoni
  • Geological Period: Jurassic
  • Stage: Middle Bajocian (~170.3 – 168.3 million years ago)
  • Location: Horn Park, Dorset, UK
  • Depositional Environment: Calm, shallow marine shelf with fine calcareous mud and marl, ideal for ammonite preservation and representative of a broad epicontinental sea

Taxonomic Classification:

  • Family: Graphoceratidae
  • Superfamily: Hildoceratoidea
  • Order: Ammonitida
  • Suborder: Ammonitina
  • Originally Described By: Sowerby (species-level), early 19th century

Morphological Features:

Ludwigia murchisoni displays a moderately involute, compressed shell with well-developed, dense, sinuous ribbing. Its ribs are fine and continuous, curving forward over the flanks to the venter without interruption. The overall shape is discoidal with a narrow umbilicus and a slightly flattened venter, contributing to its streamlined, elegant appearance.

This 8.5″ specimen beautifully retains its ribbing and shell structure, making it not only a display-worthy piece but also a scientifically diagnostic example of the genus.

Stratigraphic and Scientific Importance:

Ludwigia murchisoni is a zonal ammonite frequently associated with the Murchisonae Subzone of the Humphriesianum Zone within the British Bajocian sequence. It plays a critical role in the regional correlation of Middle Jurassic marine deposits and reflects a flourishing ammonite fauna during this interval of diversification in Western European seas.

Its occurrence at Horn Park, a designated National Nature Reserve and SSSI, adds further provenance and scientific value.

Additional Details:

  • All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.
  • Scale Rule Squares / Cube = 1cm. Please refer to the listing photo for accurate sizing.
  • This fossil is from the well-documented Alice Purnell Collection.

This is an outstanding example of a classic British Jurassic ammonite, ideal for collectors, educators, and palaeontological enthusiasts. A rare and large specimen of Ludwigia murchisoni is seldom available, especially in this condition.

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.
