Parotosuchus is an extinct genus of capitosaurian temnospondyl amphibians within the family Mastodonsauridae. Fossils are known from the Early Triassic of Europe, Africa, Australia, and Antarctica. It was about 2 metres (6.6 ft) long and likely lived in aquatic environments such as lakes and rivers. Parotosuchus was covered in a scaly skin, unlike the smooth skin of modern-day amphibians, and probably moved with an eel-like motion in the water.[2]

Parotosuchus was originally named Parotosaurus. However, the name Parotosaurus was preoccupied by a genus of skinks,[3] and in 1968 the name Parotosuchus was proposed as a replacement.[4] The name Archotosaurus was also proposed as a replacement name in 1976,[5] although the author who proposed this was unaware that Parotosuchus was already in use. Because the name Parotosuchus was erected earlier than Archotosaurus, it has priority.[6]
