"Araripesuchus wegeneri " is a small-bodied ( < 1.0 m ) crocodyliform characterized by a distinct heterodont dentition and an upright quadrupedial posture.

He obtained a Diploma in 1956 and continued on for a doctoral degree in 1957 at the University of G�ttingen-working on " Early heterodont Lamellibranchs of the Rhineland Devonian ".

Olson classified " Gorgodon " as a very early therapsid because it had a heterodont dentition and large temporal fenestra not seen in the most basal synapsids but present in therapsids.
24.
The genus name means " different toothed lizard ", in reference to its unusual, heterodont dentition; the specific name honors G . C . Tuck, who supported the discoverers.

It was reassigned to " Procaimanoidea " in 1967 by Wassersug and Hecht . " Procaimanoidea " was a small alligatorid, and slightly heterodont, the last four teeth on each side of the jaws having blunt tips.
26.
Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have " homodont " dentition, whereas those whose teeth differ morphologically are said to have " heterodont " dentition.
27.
The teeth differed slightly ( they were heterodont ) based on position : those near the tips of the upper jaws ( on the premaxillae ) were slender and lacked serrations, while those behind them ( on the maxillae ) were serrated and laterally compressed.

When first described in 1993, it was considered to be one of the earliest, if not the earliest known dinosaur . " Eoraptor " has heterodont dentition, suggesting that it was omnivorous, and that this feeding strategy had evolved early on in dinosaurs.

"' Rudists "'are a group of box-, tube-, or ring-shaped marine heterodont bivalves that arose during the Late Jurassic and became so diverse during the Cretaceous that they were major reef-building organisms in the Tethys Ocean.

A computed tomography of an exceptionally preserved skull, and examination of other specimens ( Benson et al ., 2011 ) yields new anatomical data . " Thalassiodracon " had a dorsomedian ridge on the premaxilla, a squamosal bulb, four premaxillary teeth, and a heterodont maxillary dentition.
