Marasuchus is a genus of dinosaur-like ornithodiran from the middle Triassic Period of Argentina. The Middle Triassic (also known as Muschelkalk) is the second of three epochs of the Triassic period. Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers Archosauromorpha ( Greek for "ruling lizard forms" is an Infraclass of Diapsid Reptiles that first appeared during the late Permian Ornithodira is a Clade within the larger group Archosauria In 1986 Jacques Gauthier coined the name for a node clade containing the last common In Scientific nomenclature, synonyms are different Scientific names used for a single Taxon.

The species Marasuchus illoensis was originally described as a second species of Lagosuchus, L. Lagosuchus was a small Archosaur from the Middle Triassic Period. lilloensis. However, in a restudy of Lagosuchus by Sereno and Arcucci (1994), the authors concluded that the original (type) specimen was too poorly preserved to allow any further specimens to be assigned to the genus. In Taxonomy, a type species is the species that originally defined a genus. They also noted that the L. lilloensis specimen had limb proportions different from the type species. On this basis, they assigned L. lilloensis to a new genus, Marasuchus.
