Cravens Peak Beds

Deposits containing fish fossils in the Georgina Basin, south-west Queensland - Early Devonian

The oldest shark teeth found so far, from the Early-Middle Devonian, are in this deposit. The teeth display features in common with those of the hexanchoid sharks from the Jurassic to Recent. The teeth have been ascribed to the species Mcmurdodus whitei. This genus was previously found the deposits from the Middle to Late Devonian of Antarctica. Scales and prismatic cartilage from this site are probably associated with this shark.
