Echinolampas. This list of prehistoric echinoids is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be echinoids, excluding purely vernacular terms.
The earliest echinoid fossils date to the Middle Ordovician period (circa 465 Mya). [47] [48] [49] There is a rich fossil record, their hard tests made of calcite plates surviving in rocks from every period since then. [50] Spines are present in some well-preserved specimens, but usually only the test remains. Isolated spines are common as fossils.
Andrew B. Smith designed and created a web-based, echinoid-specific approach to systematic zoology and paleontology called "The Echinoid Directory" sponsored by the Natural History Museum, London. [21] The website is driven by the international community of echinoid scientists, who contribute via through a web interface.
