Echinoids also known as sea urchins are a successful and diverse group of organisms which are still alive in the present day. The earliest known sea urchins date back from around the upper Ordovician period. Sea urchin fossil specimens often only show the main body of the animal as this is the hardest and most robust part, however, in some cases, the spines have also been fossilised. We sell many sea urchins and our specimens are available in a range of sizes and we have many species on offer, showing the variety of shapes that they are found in.
