This is a very rare and well-preserved Tetragramma varioiare regular echinoid fossil from the Chalk Basement Bed, spanning the Albian and Cenomanian stages of the Cretaceous Period, discovered in Chard, Somerset, UK. This is a highly sought-after and scientifically significant specimen, displaying the distinct features of this extinct echinoid species, making it an exceptional addition to any fossil collection.

Species Information:

Tetragramma varioiare is a rare species of regular echinoid (sea urchin) from the Cretaceous period. Unlike irregular echinoids, which evolved to burrow in sediment, regular echinoids retained their radial symmetry and typically lived on the seafloor. This species is notable for its well-defined, intricate tuberculation and overall symmetry. Fossils of Tetragramma varioiare are exceptionally rare in the UK, as their preservation in chalk formations requires unique depositional conditions.

During the Albian to Cenomanian transition (~113–93 million years ago), echinoids like Tetragramma thrived in warm shallow marine environments. Their remains provide crucial insights into the evolution of echinoids in Mesozoic ecosystems.

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
