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

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Sulcusuchus — Umfanekiso owenziwe yi-AI obonisa indlela Sulcusuchus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Sulcusuchus

?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

Inyaniso ngeentsomi

Intsomi: Some people think Sulcusuchus was a dinosaur.

Inyaniso: Sulcusuchus was a plesiosaur, a marine reptile that lived in the ocean, not a dinosaur.1

Igama lenzululwazi: Sulcusuchus
Inikwe igama ngu:: Gasparini and Spalletti 19903
Iqela: Iiplesiosauri
Usapho / iclade: Polycotylidae3
Ukuhlelwa: Plesiosauria > Sauropterygia3
Ubudala bamatye: 84 ukuya ku-66 izigidi zeminyaka (Campanian / Maastrichtian)3
Izakhiwo zamatye: La Colonia, Los Alamitos3
Amazwe: i-Argentina3
Iirekhodi zeefosili: 6 kwi-Paleobiology Database3
Ukufunyanwa: Sulcusuchus was named in 1990 by Zulma Gasparini and Luis Spalletti. The first fossil was a piece of lower jaw found in the Coli Toro Formation of Argentina.1 3
Kusaxoxwa ngayo: Scientists are not sure what the deep grooves in its snout and jaw were for. They might have held glands or electro-sensing organs, but no one knows for sure.2
