Palaeobates is an extinct genus of prehistoric elasmobranchs in the order Hybodontiformes. It lived during the Triassic period.[1] It was a small shark about 1 m (3.3 ft) long.[2] Palaeobates had a grinding-type dentition, which it used to crush hard-shelled prey. The teeth exhibit an orthodont histology.
