A few weeks ago, we heard that Tyrannosaurus sported the most powerful bite of any land animal. Dunkleosteus sported the most powerful bite in all history.

Time for Rex and the bone-headed fish to move over. The king of all bite force and his royal family want to reclaim their glory. Enter Crocodilians, unquestionably the most powerful biters ever to live on the planet. Deinosuchus wasn't included in the study, but the analyses of living crocodilians leads the researchers to believe that Deinosuchus was obviously the most powerful biter ever.
