Kinesuchus

Kinesuchus (meaning "one crocodile") is an extinct genus of notosuchian crocodylomorph from the Late Cretaceous Bajo de la Carpa Formation of Argentina. The type species, K. overoi, was described in 2018 from the holotype MAU-Pv-CO-583, a partial mandible. The genus hows affinities with the clade Peirosauria, specifically narrow-snouted forms placed in the clades Pepesuchinae or Itasuchidae. While the fossil remains are incomplete, it is distinguished from other peirosaurians by the shape of the lower jaw, which features of an elongated and rounded mandibular symphysis that is marked by a prominent constriction, giving it a somewhat spoon-shaped appearance. It inhabitet what is now northern Patagonia, which during the Santonian featured a warm and semi-arid floodplain environment with extensive river systems and sand dunes that was inhabited by a wide variety of other notosuchians as well as sauropods and theropod dinosaurs.
