       Leidyosuchus is an often mentioned genus of alligator that is known to have lived in Canada during the late Cretaceous.‭ ‬With a skull about forty centimetres long,‭ ‬Leidyosuchus would be expected to have been a mid-sized alligator and predator of small mammals and quite possibly small dinosaurs too.
       There were once many species of Leidyosuchus,‭ ‬but a‭ ‬1997‭ ‬review of the genus by Chris Brochu led to many of these species being discovered to actually represent a different genus as that represented by the type species.‭ ‬This led to the creation of the Borealosuchus genus the same year,‭ ‬and at the time of writing that genus now contains four former Leidyosuchus species renamed as species of Borealosuchus.
