Aristonectes was a huge marine reptile that swam in the seas near Antarctica and South America at the end of the Age of Dinosaurs. It had a big head, a short neck, and a body shaped a bit like a whale. It used its wide mouth to suck up food from the seafloor, just like a gray whale does today.1

makambo ya kitoko

Makambo ya kosepelisa

Aristonectes is one of the biggest and heaviest plesiosaurs ever found. One Antarctic specimen may have weighed as much as 13.5 metric tons (about 15 tons), as heavy as a large school bus.1

Unlike most plesiosaurs, which had very long necks, Aristonectes had a short neck and a big, bulky skull. Scientists put it in a special group called Aristonectinae because of this.1

Aristonectes probably migrated between Patagonia and Antarctica, just like many whales do today. Its fossils are found in both places.1

The first fossils of Aristonectes were discovered in Argentina in 1941, but scientists had a hard time studying them because the bones were not well prepared. It took decades to figure out what kind of plesiosaur it was.1

Aristonectes had a mouth that could open very wide, letting it gulp a huge amount of water and food at once. It fed by mixing prey with sediment from the seafloor, a method called benthic suction feeding.1

Like other plesiosaurs, Aristonectes probably swallowed stones called gastroliths. These may have helped grind up food in its stomach or helped control its buoyancy in the water.1

Mituna oyo batunaka mingi na ntina na Aristonectes

?How big was Aristonectes?

Aristonectes was huge, measuring more than 10 metres (33 feet) long. One Antarctic specimen may have reached 11 to 11.9 metres (36 to 39 feet) and weighed 10.7 to 13.5 metric tons (11.8 to 14.9 short tons).1 2

?What did Aristonectes eat?

Aristonectes likely ate crustaceans and small fish, based on its small teeth. It fed by sucking up prey and sediment from the seafloor, like a gray whale.1 3

?Was Aristonectes a dinosaur?

No, Aristonectes was a plesiosaur, a marine reptile that lived alongside the dinosaurs. It was not a dinosaur.1

?Where did Aristonectes live?

Aristonectes lived in the seas near Patagonia and Antarctica during the Late Cretaceous. Its fossils have been found in Chile, Argentina, and Antarctica.1

?Could Aristonectes swim?

Yes, Aristonectes was a strong swimmer, using its large paddle-like limbs to move through the water. Its name means 'best swimmer'.1

Naino bazali kowelana: Scientists are still debating exactly how Aristonectes is related to other plesiosaurs. For a long time it was thought to be a cryptoclidid, but now most agree it is an elasmosaurid.1
