Leidyosuchus
''Leidyosuchus'' (meaning "Leidy's crocodile") is an extinct genus of alligatoroid from the Late Cretaceous of Alberta. It was named in 1907 by Lawrence Lambe, and the type species is ''L. canadensis''. It is known from a number of specimens from the middle Campanian age Dinosaur Park Formation. It was a medium-sized alligatorid, with a maximum skull length greater than 40 centimeters (16 in).
A number of species had been assigned to this genus over the years, including: ''L. acutidentatus'' (Sternberg, 1932), from the Paleocene of Saskatchewan; ''L. formidabilis'' (Erickson, 1976), from the Paleocene of North Dakota and Wyoming; ''L. gilmorei'' (Mook, 1942), from the Campanian of Alberta; ''L. multidentatus'' (Mook, 1930); ''L. riggsi'' (Schmidt, 1938); ''L. sternbergii'' (Gilmore, 1910), from the Maastrichtian (Late Cretaceous) of Colorado, Montana, North Dakota, South Dakota, and Wyoming; and ''L. wilsoni'' (Mook, 1959), from the Eocene of Wyoming.〔 However, in 1997 Chris Brochu reevaluted the genus and reassigned most of the species, transferring ''L. acutidentatus'', ''L. formidabilis'', ''L. sternbergii'', and ''L. wilsoni'' to the new genus ''Borealosuchus'', and ''L. multidentatus'' to the new genus ''Listrognathosuchus'', proposing ''L. gilmorei'' as a synonym of ''L. canadensis'', and finding ''L. riggsi'' to be too fragmentary to be determinable.〔
