Amanasaurus
Amanasaurus was a plant-eating dinosaur that lived about 233 million years ago in what is now Brazil. It had a beak-like mouth and walked on four legs, munching on ferns and other plants. This dinosaur was about the size of a large dog, making it one of the bigger plant-eaters of its time.26

Datos curiosos
Amanasaurus lived during a time called the Carnian pluvial episode, a wet period when it rained a lot. Its name 'rain lizard' comes from that.12
Scientists know Amanasaurus from just two leg bones: a top part of a right thigh bone and a bottom part of a left thigh bone. These bones were found in the same spot.21
Amanasaurus was about the same size as the earliest dinosaurs that lived alongside it. This surprised scientists, who thought silesaurids were always smaller.2
The thigh bone of Amanasaurus had a special groove called a cleft between the top of the anterior trochanter and the shaft. This is the oldest such feature seen in any silesaurid.2

As preguntas máis frecuentes sobre Amanasaurus
?How big was Amanasaurus?
About 1.3 metres (4.3 feet) long, based on the larger leg bone found. That is roughly the size of a large dog.4
?Was Amanasaurus a dinosaur?
Scientists disagree. Some say it was a very early ornithischian dinosaur, while others say it was a close cousin of dinosaurs. Either way, it is a dinosauriform, meaning it is closely related to dinosaurs.51
?What did Amanasaurus eat?
It was a plant-eater. It used its beak-like mouth to munch on ferns and other plants that grew during the rainy Carnian period.4
