Luperosuchus

Luperosuchus (meaning "vexing" or "difficult crocodile") is an extinct genus of loricatan pseudosuchian reptile (historically known as a "rauisuchian") which contains only a single species, Luperosuchus fractus. It is known from the Chañares Formation of Argentina, within strata belonging to the latest Ladinian stage of the late Middle Triassic, or the earliest Carnian of the Late Triassic. Luperosuchus was one of the largest carnivores of the Chañares Formation, although its remains are fragmentary and primarily represented by a skull with similarities to Prestosuchus and Saurosuchus.

Isolated osteoderms from the same region were initially attributed this genus based on their size and similarity to those of other "rauisuchian" osteoderms, but they were later found to be belong to the contemporary erpetosuchid Tarjadia.
