Lalieudorhynchus was a herbivorous synapsid from the Middle Permian of France. It has been proposed Lalieudorhynchus had a semi-aquatic lifestyle similar to that of a hippopotamus. It belonged to the clade Caseidae, whose members are notable for their proportionately tiny heads. Lalieudorhynchus was also one of the last of the basal synapsids, termed "pelycosaurs", who had otherwise been replaced by the more mammal-like therapsids.
