Sulcusuchus was a marine reptile that lived in the seas of ancient Argentina. It had deep grooves in its snout and jaw that might have helped it sense food hiding in the mud, like a dolphin does.2

Sulcusuchus was first thought to be a crocodile, but scientists later realized it was a plesiosaur, a type of marine reptile.1

Its name means 'trough crocodile' because of the deep, groove-like channels on its jaw bones.1

The grooves on its snout and jaw may have held special organs that could detect electricity or movement, helping it find prey in murky water.2

One fossil of Sulcusuchus contained 95 gastroliths, or stomach stones, which may have helped it digest food or control its buoyancy.1

Sulcusuchus lived during the very end of the Age of Dinosaurs, about 69 to 66 million years ago.1

It is the only polycotylid plesiosaur from the Southern Hemisphere whose skull and lower jaw are known.2

?Was Sulcusuchus a dinosaur?

No, Sulcusuchus was a plesiosaur, a type of marine reptile, not a dinosaur. It lived in the seas of ancient Argentina.1 3

?How big was Sulcusuchus?

Scientists don't know its full size, but one fossil jaw fragment is about half a meter long. That suggests the whole animal was several meters long, but no exact estimate is given.1

?What did Sulcusuchus eat?

It was a carnivore, likely eating fish and other small sea animals. The grooves in its snout may have helped it sense prey hiding in the mud, like a dolphin.1 2
