Libycosuchus is an extinct genus of North African crocodyliform possibly related to Notosuchus;¹² it is part of the monotypic Libycosuchidae³ and Libycosuchinae.⁴ It was terrestrial, living approximately 95 million years ago in the Cenomanian stage of the Late Cretaceous. Fossil remains have been found in the Bahariya Formation in Egypt,⁵ making it contemporaneous with the crocodilian Stomatosuchus, and dinosaurs, including the famous Spinosaurus.¹

Discovery and naming

The holotype was discovered during the early 1910s by Richard Markgraf, and the type species, L. brevirostis, was named in 1914⁶ and described in 1915.⁵

It was one of the few fossils described by Ernst Stromer that wasn't destroyed by the Royal Air Force during the bombing of Munich in 1944.⁷
