''Fasolasuchus'' is an extinct genus of rauisuchid. Fossils have been found from Argentina that date back to the Rhaetian stage of the Late Triassic, making it one of the last rauisuchians to have existed before the order went extinct at the end of the Triassic.〔Bonaparte, J. F. 1981. Description de “''Fasolasuchus tenax''” y su significado en la sistemarica y evolucion de los thecodontia. ''Revista del Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”'' 3:55–101.〕〔Bonaparte, J. F. (1986). Locomotion in Rauisuchid Thecodonts. ''Journal of Vertebrate Paleontology'' 3(4):210-218.〕 It is quite possibly the largest known member of Rauisuchia, with an estimated length of 8–10 meters (26.4–33 ft), even bigger than the prestosuchid ''Saurosuchus'' at 7 meters (23.1 ft) in length. This would make ''Fasolasuchus'' the largest terrestrial predator to have ever existed save for large theropods. Like ''Saurosuchus'', it had only a single row of caudal osteoderms, unusual among rauisuchians.〔Sulej, T. (2005). A new rauisuchian reptile (Diapsida: Archosauria) from the Late Triassic of Poland. ''Journal of Vertebrate Paleontology'' 25(1):78–86.〕 It also had a hyposphene-hypantrum articulation that gave the vertebral column extra rigidity. This feature is also seen in several other rauisuchians such as ''Postosuchus'' as well as saurischian dinosaurs.〔Weinbaum, J. C. and Hungerbüler, A. (2007).
