Leina le raya: “lizard from La Rioja”1

E jele: DimelaMelala-meleeleBofelo jwa Triassic

Riojasaurus was a huge, plant-eating dinosaur with a long neck and a heavy body. It lived during the Late Triassic period in what is now Argentina. It probably walked slowly on all four legs, munching on leaves with its leaf-shaped teeth.1

Riojasaurus had very dense and massive leg bones, making it heavy and sturdy for an early sauropodomorph.1

Unlike most early relatives, Riojasaurus had four sacral vertebrae in its hip area instead of three, which helped support its weight.1

Its neck bones were longer than those of other sauropodomorphs found in the same formation, making its neck especially long.1

The first Riojasaurus skeleton found had no skull. A well-preserved skull was later discovered in 1987 and described in 1995.1

Some scientists think Riojasaurus may have been active at short intervals throughout the day and night, based on the shape of its eye bones (scleral rings).1

Riojasaurus is the only known riojasaurid dinosaur from South America, and it may be closely related to Melanorosaurus from southern Africa.1

Its front and hind limbs were nearly the same length, which is a clue that it walked on all fours and could not rear up on its back legs.1

Dipotso tse di botswang thata ka ga Riojasaurus

?How big was Riojasaurus?

Riojasaurus was about 6.6 metres (21.7 feet) long and weighed around 800 kilograms (1,764 pounds). Some large individuals may have reached 10 metres (32.8 feet) long and weighed 3 metric tons (3.3 short tons).1

?What did Riojasaurus eat?

Riojasaurus was a herbivore that ate plants. Its leaf-shaped, serrated teeth were used for grazing on soft vegetation like gymnosperms, and it may have swallowed stones (gastroliths) to help grind food in its stomach.1 3

?Could Riojasaurus walk on two legs?

No, Riojasaurus probably walked on all four legs. Its front and hind limbs were nearly the same length, and its leg bones were dense and massive, suggesting it moved slowly on all fours and could not rear up on its back legs.1

?When did Riojasaurus live?

Riojasaurus lived during the Late Triassic Period, about 225 to 213 million years ago. Its fossils have been found in the Los Colorados Formation in Argentina.1

?Is Riojasaurus a dinosaur?

Yes, Riojasaurus is a dinosaur. It is a herbivorous sauropodomorph dinosaur from the Late Triassic of Argentina.1

?Did Riojasaurus have feathers?

No, there is no evidence that Riojasaurus had feathers. Its fossils show only scales and bones, and it is not known to have any feather-like structures.1

Go fitlhelwa: Riojasaurus was named by Argentine paleontologist José Bonaparte in 1969. The first skeleton (holotype PVL 3808) was found in 1966 in the Los Colorados Formation of La Rioja, Argentina. Later, many more skeletons and a skull were discovered.1 4
Go sa ntse go ganetsanwa: Scientists disagree on whether Riojasaurus was completely quadrupedal or could sometimes walk on two legs. The hand and shoulder bones suggest it might have been able to move in different ways.1
