Utuntu dushimishije

1

Guaibasaurus fossils have been found in a sleeping posture, with legs tucked under the body and arms bent to the side, similar to modern birds.2

2

This dinosaur lived about 225.42 million years ago, based on uranium-lead dating of the rocks where its fossils were found.2

3

Scientists are not sure if Guaibasaurus was an early theropod or an early sauropodomorph. Most studies place it among the sauropodomorphs.21

4

The name Guaibasaurus comes from the Rio Guaíba basin in Brazil, where the first fossil was discovered during a scientific project.21

5

Only one species of Guaibasaurus is known, called Guaibasaurus candelariensis. The species name honors the nearby city of Candelária.2
