Libonectes

Leina le raya: “southern swimmer”1

E jele: NamaDipleisiosoroBofelo jwa CretaceousKa saense, ga se dinosoro

Libonectes was a long-necked marine reptile that swam in warm seas during the time of the dinosaurs. It used its strong flippers to paddle through the water and may have swallowed fish and ammonites whole. Fossils show it had a skull that is one of the best preserved of any elasmosaurid plesiosaur.1

Libonectes had a neck that was 5.06 metres (16.6 feet) long, more than two-thirds of its total body length.1

The first fossils were found by a farmer named T.W. Tidwell in the late 1930s in Texas.1

Its skull is the best preserved skull of any elasmosaurid plesiosaur ever found.1

Libonectes lived about 93 million years ago, during the Late Cretaceous period.3

It was originally named Elasmosaurus morgani in 1949, but was given its own genus, Libonectes, in 1997.1

Gastroliths (stomach stones) have been found inside Libonectes fossils, which may have helped it digest food or control its buoyancy in the water.1

Libonectes probably swam slowly and used its large size to trap prey.1

?How big was Libonectes?

Libonectes was a medium-sized plesiosaur, about 7.2 metres (24 feet) long. Its neck alone was 5.06 metres (16.6 feet) long.1

?What did Libonectes eat?

Libonectes probably ate small fish and ammonites. It may have swallowed prey whole and used stomach stones to help digest food.1

?Where was Libonectes found?

Fossils of Libonectes have been found in Texas, USA, and in Morocco. This shows it lived in warm seas on both sides of the Atlantic Ocean.1 2

Mothubi wa ditlhamane

Tlhamane: Some people think plesiosaurs like Libonectes could lift their heads and necks high out of the water like a swan.

Boammaaruri: Scientists now believe their necks were not flexible enough to lift high above the water. They probably held their necks more horizontally while swimming.1

Go fitlhelwa: The first Libonectes fossils were found by tenant farmer T.W. Tidwell in the late 1930s in Texas. Charles Gill Morgan prepared the fossils, and the species was named Elasmosaurus morgani by Welles in 1949. It was reclassified as its own genus Libonectes by Carpenter in 1997.1
Go sa ntse go ganetsanwa: Scientists are not sure whether Libonectes was a pure carnivore or an omnivore, because gastroliths could indicate plant eating or just buoyancy control.1
