description Echinocorys scutata Overview
Echinocorys scutata is an extinct species of irregular sea urchin that existed during the Late Cretaceous to Paleocene periods. As a holasterid echinoid, it possessed the flattened, heart-shaped or scutate test characteristic of its group, adapting it to a burrowing lifestyle in soft marine sediments. Fossils of this organism are commonly found preserved in chalk and limestone formations across Europe, Asia, and North America. Paleontologists use this species as a valuable index fossil for dating and understanding marine paleoenvironments.
help Echinocorys scutata FAQ
How old are Echinocorys scutata fossils?
Echinocorys scutata fossils date from the Late Cretaceous through the Paleocene, roughly 70 to 60 million years ago. This range spans the end-Cretaceous mass extinction event that wiped out the non-avian dinosaurs.
Where can I find Echinocorys fossils?
Echinocorys fossils are found across Europe, Asia, Australia, and North America. They are particularly common in Late Cretaceous chalk deposits, such as the white chalk exposures of southern England, Denmark, and northern Germany.
What did Echinocorys scutata look like?
Echinocorys scutata was a holasterid sea urchin, meaning it had an elongated or heart-shaped test rather than the perfectly round form of regular sea urchins. This asymmetrical body shape was an adaptation to burrowing in soft seafloor sediment.
Are Echinocorys fossils common?
Yes, Echinocorys scutata is one of the more commonly encountered fossil echinoids due to its broad geographic range and the abundance of chalk and limestone deposits from the Late Cretaceous. Collectors frequently find well-preserved specimens in European chalk formations.
