These fossilized sea urchins are petrified remains of echinoderm marine organisms that lived predominantly during the Mesozoic Era, which spans from 252 to 66 million years ago. Typically preserved in sedimentary rock, these fossils have retained the rounded shape and star-like patterns characteristic of modern sea urchins. Their color generally ranges from light brown to ocher yellow, these shades resulting from mineralization over geological epochs. Often found in groups, these fossils bear witness to their former life in shallow marine environments.
In good condition, these sea urchins will make an excellent addition to any fossil collection for paleontology enthusiasts.
The size of these fossils is approximately 3 cm. Their varied color and unique fossilization attest to their authenticity.
