Jiangxisuchus is an extinct genus of crocodylian that lived during the Late Cretaceous in what is now China. It was described in 2019, and was proposed to be a basal member of Crocodyloidea.[2][1] However, another concurrent 2019 study recovered Jiangxisuchus instead as a basal member of Alligatoroidea, within the newly named clade Orientalosuchina.[3]
