名字的意思： “sand lizard”1

吃：植物長脖子恐龍侏羅紀早期

Ammosaurus was a long-necked dinosaur that lived during the Early Jurassic, about 195 to 180 million years ago. It was a plant-eater that probably walked on all fours but could stand on its hind legs to reach high plants. Fossils of this dinosaur have been found in the USA and Canada.1 2

酷東西

趣味知識

Ammosaurus was once called Yaleosaurus, named after the famous Yale University.4

Some scientists think Ammosaurus might actually be the same dinosaur as Anchisaurus, just a larger individual.2

Fossils of Ammosaurus were found in a bridge abutment in Connecticut, USA, when the bridge was demolished in 1969.2

Ammosaurus lived in a dry environment with strong wet and dry seasons, like a desert today.2

Its spoon-shaped teeth were perfect for ripping plants, and it had fewer teeth than many other prosauropods.2

?How big was Ammosaurus?

Ammosaurus was about 2.5 to 4 metres long and weighed up to 32 kilograms.2 1

?What did Ammosaurus eat?

Ammosaurus was mainly a plant-eater, but it might have eaten small animals sometimes. It swallowed stones called gastroliths to help grind up food in its stomach.2 1

?When did Ammosaurus live?

Ammosaurus lived during the Early Jurassic Period, about 200 to 185 million years ago.1 2

?Where was Ammosaurus found?

Fossils of Ammosaurus have been found in the USA and Canada, including in Connecticut, Massachusetts, and Nova Scotia.2 1

?Is Ammosaurus the same as Anchisaurus?

Many scientists now think Ammosaurus is actually just a larger individual of Anchisaurus, so they are probably the same dinosaur.2 3

?Did Ammosaurus have feathers?

The sources do not mention feathers on Ammosaurus, so scientists do not know for sure if it had them.2 1

迷思破解王

迷思： Ammosaurus was a giant, fearsome predator.
