Paraisurus is an extinct genus of mackerel sharks that lived during the Cretaceous. It contains four valid species, which have been found in Europe, Asia, North America, and Australia .[5] A fifth species, P. amudarjensis, is now considered a synonym of P. compressus.[6] While this genus is mostly known from isolated teeth, an associated dentition of P. compressus was found in the Weno Formation of Texas .[7] It went extinct around the Albian-Cenomanian boundary, as a supposed Coniacian occurrence of "P. sp." is likely a misidentified pseudoscapanorhynchid.[8]
