Silosaurs are classified as reptiles rather than early dinosaurs. However, out of more than 20 fossils found, Silezaurus can be classified as a dinosaur.
Silosaurs resemble the dinosaurs of the Archosaur group. These dinosaurs are relatively small, agile and light. They are thought to have fed on the remains of prey left by other carnivorous dinosaurs.
They lived in herds because of their inability to defend themselves. They are thought to have been able to climb trees, leading some scientists to believe that they belong in the family of bird-bottomed dinosaurs.
