Discovery and classification edit
Unasuchus 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.
