Scutella - Natural minerals and crystals

Scutella is an extinct genus of echinoderms, specifically an echinid, that lived during the Mesozoic era, specifically from the Jurassic to the Cretaceous. These marine organisms are characterized by their disc-shaped test (shell), composed of interlocking calcium carbonate plates, and by their radial symmetry. Their internal structure is composed of numerous tubules and radioles which allowed them to move and feed. The genus Scutella is particularly known for the beauty of its fossils, which often exhibit exceptional preservation of structural details.
