 It is believed that "Desmatosuchus" dug for food in the soft mud near bodies of water due to the abundance of lakes and rivers in the Dockum area and the fact that "Desmatosuchus" scutes are often found among parts of other reptiles that are known to have fed along waterways.It is unknown whether or not "Desmatosuchus" replaced their teeth and, if so, how.The low number of "Desmatosuchus" teeth that have been discovered indicates that they were only held in place by soft tissue connections.
