In Depth

       Although Acherontisuchus was named upon the basis of four specimens,‭ ‬there is the possibility that these remains may be all from the same individual.‭ ‬Acherontisuchus were dyrosaurid crocodiles that inhabited the rivers and water‭ ‬systems of Colombia.‭ ‬Acherontisuchus grew quite a bit bigger than other dyrosaurid crocodiles,‭ ‬and although long-snouted,‭ ‬also differed by having a snout that was proportionately shorter than relatives like Dyrosaurus.‭ ‬Attachments for fairly strong back and leg muscles suggest that Acherontisuchus would have also been quite capable at roaming about on land.
