Mesoeucrocodylia is the clade that includes Eusuchia and crocodyliforms formerly placed in the paraphyletic group Mesosuchia. The group appeared during the Early Jurassic, and continues to the present day.
==Diagnosis== thumb|left|Crocodilaemus|Crocodilaemus robustus It was long known that Mesosuchia was an evolutionary grade, a hypothesis confirmed by the phylogenetic analysis of Benton and Clark (1988) which demonstrated that Eusuchia (which includes all living crocodylian species) was nested within Mesosuchia. Due to the paraphyly of Mesosuchia, Mesoeucrocodylia was erected to replace Mesosuchia.
