Sinornithosaurus is a Dromeaosaur from early Cretaceous China. Most of this information is found in the video of Sinornithosaurus and here is the link (see button below)
It was 5 feet long and 15 pounds. It had a long Dromeaosaur killing claw, and it was probably used in ambush attacks from the trees on other smaller dinosaurs, even if they are carnivorous. Sinornithosaurus has very flexible shoulders that might have allowed it to climb trees.
