Caipirasuchus is an extinct genus of sphagesaurid notosuchians known from the Late Cretaceous of northern São Paulo State and western Minas Gerais State, southeastern Brazil. The type species, C. paulistanus, was named in 2011.[1] A second species, C. montealtensis, was referred to Caipirasuchus in 2013 after having been named in 2008 as a species of Sphagesaurus.[2] A third species, C. stenognathus, was described in 2014.[3] A fourth species, C. mineirus, was described in 2018.[4] A fifth species, C. attenboroughi, was named in 2021 in honour of David Attenborough,[5] and a sixth species, C. catanduvensis, was described in 2024, with a distinct chamber associated with the airways, possibly used in vocalization.[6]
