In Depth
Although the last part of the name ‘suchus’ is ancient Greek for crocodile, Sulcusuchus was actually a plesiosaur, a member of the famous group of long necked marine reptiles of the Mesozoic. In more specific terms it is considered to be a polycotylid plesiosaur, with one of the more famous members of this group being Dolichorhynchops. Like with its close relatives, Sulcusuchus is noted for having a proportionately short neck with jaws longer than most other types of plesiosaur. Other late Cretaceous plesiosaurs known from South America include Aristonectes, although this was quite different from Sulcusuchus.
