Fossil remains have been found in the Bahariya Formation in Egypt, making it contemporaneous with the crocodilian Stomatosuchus, and dinosaurs, including the famous Spinosaurus.

Discovery and naming

The holotype was discovered during the early 1910s by Richard Markgraf, and the type species, L. brevirostis, was named in 1914 Stromer (1914), p. 28 and 29, fn. 1 and described in 1915.Original citation: Stromer, E.

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.{{cite journal |last1=Tumarkin-Deratzian |first1=Allison |last2=Grandstaff |first2=Barbara S. |last3=Lamanna |first3=Matthew |last4=Smith |first4=Joshua B. |title=New material of Libycosuchus brevirostris from the Cenomanian Bahariya Formation of Egypt |journal=Journal of Vertebrate Paleontology |date=September 2004 |volume=24 |issue=3 |page=123A |url=https://www.researchgate.net/publication/264042847 |accessdate=3 November 2020}}
