• Geological Age: Oxfordian stage, Jurassic period, 163 to157 million years ago.
• Location: Basal corallian beds in Wicken, Cambridgeshire, UK.
• Family: Echinoderm
• Species: Collyrites bicordatus
Collyrites bicordatus fossil echinoid specimens found the Basal corallian beds of Wicken, Cambridgeshire, UK. The beds formed in the Jurassic period, dating the fossils to over 160 million years old. These species have a disc shaped body, the samples of which have been cleaned to remove matrix from them, allowing for better observation of the features. They measure roughly 5 cm in diameter and come supplied in a card tray with a data label.
Collyrites bicordatus is an extinct genus of echinoid which lived during the Oxfordian stage of the Jurassic period, between 163 to 157 million years ago. Like many echinoid, the species has a disc shaped body and is somewhat flat compared to some other species such as the collyrites elliptica. The specimens have been professionally prepped and cleaned, so that they are free of matrix. Collected from the Basal corallian beds in Wicken, Cambridgeshire, from which this particular species derives its name from, they are fairly well detailed, with patterns being seen easily with the naked eye and are approximately 5 cm in diameter and come supplied in a card tray with a label.
