Calamosuchus is an extinct genus of probable early phytosaurian reptiles known from the Late Triassic (Carnian age) Stuttgart Formation of Germany. The genus contains a single species, Calamosuchus arenaceus, known from a partial mandible. The species was first described in 1896 by Eberhard Fraas, who assigned it to the genus Zanclodon as Z. arenaceus. Although researchers have noticed substantial differences between Z. arenaceus and the Z. laevis (the type species) since 1902, it did not receive a distinct genus name until 2025, when it was placed in the new genus Calamosuchus.
