Trace Fossil Borings from Bivalve and Annelid – Faringdon Sponge Gravels, Kimmeridge Clay, Jurassic (Re-worked into Cretaceous, Aptian) – Wicklesham Pit, Faringdon, Oxfordshire, UK

100% Genuine Fossil with Certificate of Authenticity

We are thrilled to offer this trace fossil boring specimen, which was formed by bivalves and annelids. These trace fossils were found in the Faringdon Sponge Gravels, part of the Kimmeridge Clay formation, located in Wicklesham Pit, Faringdon, Oxfordshire, UK. The fossils date from the Jurassic Period, but the specimen has been re-worked into overlying Cretaceous sediments (Aptian). The borings are representative of ancient bivalve and annelid activity, where these organisms bored into the substrate, leaving behind distinctive marks in the rock.

Geological and Fossil Information:

  • Fossil Type: Trace Fossil Borings from Bivalve and Annelid
  • Species: Bivalve and Annelid (trace fossil genus)
  • Morphology Features: The borings are cylindrical and irregular, characteristic of bivalve and annelid organisms. The preservation of these borings shows the burrowing behavior of these organisms as they interacted with the substrate. The Faringdon Sponge Gravels display clear marks of these ancient activities.
  • Geological Stage: Jurassic (Kimmeridge Clay), Re-worked into Cretaceous (Aptian) (~125 million years ago)
  • Depositional Environment: These trace fossils were formed in a shallow marine environment during the Jurassic Period, but the specimen was later re-worked into overlying Cretaceous deposits. The environment during the Cretaceous Aptian was likely still shallow marine, with bivalves and annelids living in soft sediments that allowed them to create their burrows.
  • Biozone: This fossil falls within the Kimmeridge Clay biozone of the Jurassic period, though it has been reworked into Cretaceous sediments during the Aptian stage.
  • Family: Not applicable (trace fossils)
  • Super Family: Not applicable (trace fossils)
  • Order: Trace Fossils (Ichnology)
  • Formally Identified By: This fossil has been formally identified based on its morphological features and the geological context of its discovery at Wicklesham Pit, Faringdon, Oxfordshire, UK.

Size and Visuals:

The fossil measures approximately as shown in the attached photo. Please refer to the scale rule (1cm squares) for accurate size reference. The photo shown is of the actual specimen you will receive, carefully chosen to highlight its exceptional preservation and intricate details of the borings.

Authenticity and Certification:

All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity, ensuring the provenance and authenticity of the fossil. This trace fossil boring from the Faringdon Sponge Gravels offers a fascinating glimpse into the behavior of ancient bivalves and annelids, making it a valuable addition to any fossil collection.

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.
