C. paulistanus has about ten autapomorphies or unique characteristics.
The external naris (the nostril opening in the skull) is bordered only by the premaxillae bones.
Each premaxilla has four teeth set into it.
There is a gap called a diastema in the premaxillary tooth row, and a diastema in between the premaxillary and maxillary teeth.
The dentary bone of the lower jaw has ten teeth on either side, with two diastemata separating them.
The forward-most teeth are suited for capturing food, while the back teeth are adapted for food processing.
The palatine bone in the roof of the mouth connects to the maxilla bone of the snout by a region of bone called the cuneiform process.
Caipirasuchus also has large pterygoid and ectopterygoid bones  and a well-developed hole in front of the eye sockets called the antorbital fenestra.
