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.
