Caipirasuchus is a sphagesaurid crocodyliform genus known from Upper
Cretaceous rocks (Turonian–Santonian) of the Bauru Basin, Brazil.
Although their earlier descriptions were restricted to skull and
mandible morphology, three species have been identified. In the
present study, the skeletons of three specimens were analyzed from the
collection of Prof. Antonio Celso de Arruda Campos Paleontology
Museum: Caipirasuchus montealtensis (MPMA 68-0003/12), Caipirasuchus
paulistanus (MPMA 67-0001/00) and Caipirasuchus sp. (MPMA 07-0011/00).
These specimens are three individuals of a very similar size and have
the same postcranial morphology. Analysis of the Caipirasuchus
skeletons indicate the species were approximately 1.10 m in length and
had slender-long bodies and hind limbs twice as long as the forelimbs.
Regarding the general postcranial morphology of Caipirasuchus results
indicate that these were agile animals and used speed as a defense
mechanism against predators.
