Abstract: The oldest echinoderm faunas have previously been restricted to North America and had a radiate body plan. This discovery of echinoderms from Morocco reveals a diverse range of body forms just 15 million years after echinoderms first evolved a calcite skeleton, showing a rapid rate of morphological evolution.
