Discovery and classification
editUnasuchus is known only from skull and jaw fragments, meaning that it initially defied precise classification within Crocodyliformes, but the cladistic analysis of Turcosuchus recovers Unasuchus as a derived hylaeochampsid.[2][3] These remains have been found from the Barremian Las Hoyas Formation.[4] The type species, U. reginae, was named in 1992.
