Thalassinoides Trace Fossil Burrows, Upper Chalk, Cretaceous – Ruscombe Field, UK – Genuine with Certificate of Authenticity

Description Thalassinoides Trace Fossil Burrows – Upper Chalk, Cretaceous – Ruscombe Field, UK 100% Genuine Fossil with Certificate of Authenticity We are pleased to offer this stunning Thalassinoides trace fossil burrow specimen, discovered in Ruscombe Field, UK. This fascinating trace fossil dates from the Upper Chalk of the Cretaceous Period, approximately 70-100 million years ago. Thalassinoides is a genus of trace fossils created by ancient organisms, often thought to be burrowing crustaceans, which left behind branching burrows that have been preserved in the sediment. Geological and Fossil Information: Fossil Type: Thalassinoides trace fossil burrows Species: Thalassinoides (trace fossil genus) Morphology Features: The Thalassinoides burrows are branching tunnel-like structures that represent the activity of burrowing organisms. These distinctive structures are preserved in fine detail, providing valuable insight into ancient ecosystems. Geological Stage: Upper Chalk, Cretaceous (~70-100 million years ago) Depositional Environment: The burrows were formed in shallow marine environments where burrowing organisms, likely crustaceans, created these tunnel-like structures. The Upper Chalk represents a period of deep marine deposition, but these burrows suggest significant activity near the seabed. Biozone: The specimen belongs to the Upper Chalk biozone, which is characterized by the deposition of chalky sediments in marine environments during the Cretaceous 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 by paleontologists based on its morphological features and the geological context of its discovery in Ruscombe Field, UK. Size and Visuals: The fossil measures approximately as shown in the accompanying photo. A scale rule (1cm squares) is included for accurate size reference. The photo shown is of the actual specimen you will receive, carefully selected to highlight its exceptional preservation and intricate details. Authenticity and Certification: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity, guaranteeing the fossil’s provenance and authenticity. This Thalassinoides trace fossil burrow from the Upper Chalk is a rare and valuable specimen that offers a unique view into the life and behavior of prehistoric organisms.
