It has a well-described braincase and brain cavity, and has greatly informed our understanding of the skull, brain, nerves, and jaws of early sharks. Cladodoides is likely a cladodont shark. Remains have been found in Germany.
Six pentacuspid teeth, possibly belonging to Cladodoides wildungensis, have been found in the Tournaisian Laurel Formation, Australia.[1]
