Sinornithosaurus was one of the first dinosaurs discovered with feathers. It lived during the Early Cretaceous, 130–125 million years ago. Its name is derived from the Greek, ‘chinese bird-lizard’, and is pronounced: SINE-or-nith-oh-SAWR-us.
Feeding and diet
Sinornithosaurus was an active and agile carnivorous species that probably hunted in groups.
Other behaviours and adaptations
Sinornithosaurus was probably adapted for leaping. Its rigid tail acted as a counterbalance, allowing pinpoint accuracy and freeing the powerful feet claws. Whether this helped in attacking prey or leaping among tree branches is difficult to say.
