Bergisuchus is an extinct genus of sebecosuchian mesoeucrocodylian. Fossils have been found from the Eocene Messel Pit in Germany. Bergisuchus was originally classified as a sebecosuchian, supposedly the first to be found outside South America, and later assigned to Trematochampsidae in 1988.[1] Later that year it was reclassified as a basal baurusuchid.[2] In 2000, the genus was given its own family, Bergisuchidae.[3]

Bergisuchus is known from a holotype rostrum from the Messel Pit, first described in 1966, and a mandible from an open-pit coal mine near Halle in the state of Saxony-Anhalt.[3] The Messel Pit is famous for its well-preserved fossils, which include semiaquatic crocodyliforms such as Asiatosuchus and Diplocynodon. Unlike other crocodyliforms present in the Messel Pit, Bergisuchus was a small terrestrial hypercarnivore.[4]
