Prettige feite
Hanosaurus lived about 250 to 247 million years ago, during the Early Triassic period.3
It was a basal sauropterygian, meaning it was an early relative of plesiosaurs and other famous sea reptiles.2
Its body was long and slender, with short limbs, which made it an axial swimmer, it moved by wiggling its body like a fish, not by paddling with its flippers.12
Hanosaurus had thick, heavy ribs (pachyostotic ribs) that probably helped it stay underwater without floating up.1
Its pelvis was very reduced, so it likely could not walk on land and spent its whole life in the water.1
The first fossil of Hanosaurus was a skull, backbone, hips, and hind legs, but no tail or front legs were found with it.1
Mees gevraagde vrae oor Hanosaurus
?How big was Hanosaurus?
About 79.4 cm long. That is a little shorter than a 91.4 cm yardstick.1
?What did Hanosaurus eat?
It likely ate small, soft-bodied prey like worms or tiny shrimp. Its teeth and jaw muscles were suited for soft food.14
?Could Hanosaurus walk on land?
No, it probably could not. Its heavy ribs helped it stay underwater, and its pelvis was too weak to support its weight on land.12
?Is Hanosaurus a dinosaur?
No, it is a marine reptile called a sauropterygian. It is an early relative of plesiosaurs, not a dinosaur.1

- Hanosaurus was named by Chinese paleontologist Yang Zhongjian (also known as C.C. Young) in 1972, based on a partial skeleton found in Hubei, China.13
- Steeds omstrede
- Scientists are still debating whether a more complete skeleton found later really belongs to Hanosaurus or to a different species.1
