Palaeobates

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

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.

Palaeoecology

Dental microwear analysis of P. angustissimus confirms that it was a durophagous predator, eating bivalves, gastropods, crustaceans and/or echinoderms.3
