Sinornithosaurus

† Sinornithosaurus is an Early Cretaceous dromaeosaurid from the Yixian Formation of China, among the first nearly complete feathered non-avian dinosaurs described. Its feathers preserved in exquisite detail advanced understanding of dinosaur-bird evolution.

Diet & Feeding

Carnivore

Sinornithosaurus was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Early Mesozoic Era

Sinornithosaurus lived during the Cretaceous Early period of the Mesozoic Era, approximately 145,0 to 100,5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
