==Discovery and naming== thumb|left|Mandibular symphysis of the first three named species Caipirasuchus was first named by Fabiano V. Iori and Ismar S. Carvalho in 2011 and the type species is C. paulistanus. The generic name is derived from Tupi word Caipira which refers to the traditional inhabitants of interior of São Paulo, covering almost all of the Bauru Basin, and Greek souchus meaning "crocodile". The specific name is derived from "Paulista", the designation for the residents of São Paulo State, where the holotype was found.
