Liaoningosaurus
Liaoningosaurus was a tiny armoured dinosaur that lived in what is now China. It was so small that a full-grown one was only about as long as a ruler! Scientists think it might have been able to swim and eat fish, which is very unusual for an armoured dinosaur.12

Datos curiosos
Liaoningosaurus is the smallest known armoured dinosaur. The first fossil found was only 34 centimetres (about 13 inches) long.2
It had a large bony plate on its belly that looked like a shell. No other armoured dinosaur has such a plate.2
Some scientists think Liaoningosaurus could swim. Its skeleton has features that might help it paddle in water.1
Fossilized fish bones were found inside the stomach of one Liaoningosaurus. This suggests it ate fish, which is rare for an armoured plant-eater.1
Liaoningosaurus lived about 125 to 119 million years ago during the Early Cretaceous period.3
It is the oldest known armoured dinosaur that had a tail club. The tail club could have been used for defence.1
More than 20 fossils of Liaoningosaurus have been found, all from young animals. No adult has been discovered yet.1
As preguntas máis frecuentes sobre Liaoningosaurus
?Was Liaoningosaurus a dinosaur?
Yes, it was a small armoured dinosaur called an ankylosaurid.1
?How big was Liaoningosaurus?
It was tiny. The first fossil found was only 34 centimetres (about 13 inches) long. The largest known specimen was less than 45 centimetres (about 18 inches) long.1
?Did Liaoningosaurus eat fish?
Some scientists think so. Fish bones were found inside the stomach of one fossil, but not all experts agree it ate fish.1
?Could Liaoningosaurus swim?
Maybe. Some scientists think it was semiaquatic because of its shell-like belly plate and other features, but others disagree.1

It had the handle part of a tail club, but not the big knob at the end. It is the oldest known ankylosaurid to have a tail club handle.1
