Description

This is Diplopodia subangularis, an sea urchin. Diplopodia is a congenital anomaly in tetrapods that involves duplication of elements of the foot on the hind limb. It comes from the Greek roots diplo = "double" and pod = "foot". Diplopodia is often found in conjunction with other structural abnormalities and can be lethal. It is more extreme than polydactyly, the presence of extra digits. It lived 170 to 89.3 mya, in the middle Malm age. This specimen contains high Mg calcite based on Echinoidea.
