EDITORS COMMENTS
This print showcases the ancient and intricately detailed form of Tylocidaris clavigera, an extinct sea-urchin species discovered in the Upper Cretaceous Upper Chalk formation of Southern England. Hailing from the Mesozoic Era, approximately 80-83 million years ago, this echinoid is a remarkable relic from the Phanerozoic Coniontide, an era characterized by the evolution and diversification of invertebrates. The Tylocidaris clavigera is easily recognizable by its distinctive club-like spines, which are densely packed and uniformly arranged around its spherical body. This sea urchin, a member of the Cidaridae family, once inhabited the sedimentary rock formations of the English Channel. The sedimentary rock in which this prehistoric creature was found is a testament to the rich history of marine life that once thrived in the waters surrounding the British Isles during the Cretaceous Period. The Chalk formation, a type of sedimentary rock, is renowned for its high content of calcium carbonate, which was deposited by the accumulation of microscopic organisms called foraminifera. As an echinoid, Tylocidaris clavigera is part of the larger Echinodermata phylum, which includes other well-known marine invertebrates such as starfish and sea cucumbers. The Echinoidea order, to which this species belongs, is characterized by the presence of a test or shell, which provides protection and support. This studio shot offers a rare glimpse into the past, allowing us to appreciate the beauty and complexity of life that once existed in the Mesozoic Era. The intricate details of the Tylocidaris clavigera's spines and body structure are a testament to the remarkable preservation of this ancient specimen, making it a valuable addition to any collection or display of prehistoric marine life.
