       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.
