Acynodon is an extinct genus of eusuchian crocodylomorph from the Late Cretaceous, with fossils found throughout Southern Europe.

Fossils have been found in France, Spain, Italy, and Romania, dating back to the Santonian and Maastrichtian periods of the Late Cretaceous.

[3][1] Recent studies have since resolved Acynodon as a basal eusuchian crocodylomorph, outside of the Crocodylia crown group, and a close relative to Hylaeochampsa.

[4][5][6] The skull of Acynodon is extremely brevirostrine; it had a very short and broad snout compared to other known alligatorids.

A. adriaticus was highly specialized to durophagy, likely in shallow, densely vegetated waters.
