Description
Thalassinoides Trace Fossil Burrows – Forest Marble, Great Oolite, Jurassic – Herbury Head, UK
100% Genuine Fossil with Certificate of Authenticity
We are pleased to present this remarkable Thalassinoides trace fossil burrow, discovered in the Forest Marble of the Great Oolite at Herbury Head, UK. This fossil dates from the Jurassic Period, providing an exceptional glimpse into ancient marine life. The Thalassinoides genus is known for its distinct burrowing activity, which is preserved in the form of branching tunnel-like structures that represent the behavior of ancient organisms, most likely marine crustaceans.
Geological and Fossil Information:
- Fossil Type: Thalassinoides trace fossil burrows
- Species: Thalassinoides (trace fossil genus)
- Morphology Features: The Thalassinoides burrows exhibit distinctive, branching structures that are characteristic of the burrowing behavior of ancient marine organisms. The tunnel-like features are intricately preserved, showing the complex patterns formed as these creatures created their burrows.
- Geological Stage: Jurassic (~200-145 million years ago)
- Depositional Environment: The fossil was formed in a shallow marine environment, typical of the Great Oolite deposits. This suggests a dynamic marine ecosystem where burrowing organisms such as crustaceans thrived, leaving behind these intricate trace fossils.
- Biozone: The specimen is part of the Forest Marble biozone, which is known for its marine deposits from the Middle Jurassic period.
- Family: Not applicable (trace fossils)
- Super Family: Not applicable (trace fossils)
- Order: Trace Fossils (Ichnology)
- Formally Identified By: This fossil has been professionally identified based on its morphological characteristics and the geological context of its discovery in the Forest Marble, Great Oolite, Herbury Head, UK.
