Sinornithosaurus (derived from a combination of Latin and Greek, meaning 'Chinese bird-lizard') is a genus of feathered dromaeosaurid dinosaur from the early Cretaceous Period (early Aptian) of the Yixian Formation in what is now China. It was the fifth non–avian feathered dinosaur genus discovered by 1999. The original specimen was collected from the Sihetun locality of western Liaoning. It was found in the Jianshangou beds of the Yixian Formation, dated to 124.5 million years ago. Additional specimens have been found in the younger Dawangzhangzi bed, dating to around 122 million years ago. Xu Xing described Sinornithosaurus and performed a phylogenetic analysis which demonstrated that it is basal, or primitive, among the dromaeosaurs. Some paleontologists have hypothesized that Sinornithosaurus millenii had venom due to some dentitional similarities to modern venomous snakes. Lately; the possiblity that this Dinosaur species could be Venomous is highly debated.

Discovery and specimens

In the Media

  • Sinornithosaurus makes an appearance in the episode Feathered Dragons in Planet Dinosaur, where it is first shown to prey on a smaller relative, Microraptor, but fails. Sinornithosaurus is later shown to have a poisonous bite by comparing its teeth to the Gila Monster lizard. A pack of Sinornithosaurus have taken down a mother Jeholosaurus with the help of their poison, orphaning her babies.
  • It was seen in the television show Dino Dana. It apparently is shown with a purple-feathered body, whereas the real animal had orange/brown feathers.

Trivia

Lately, the theory of Sinornithosaurus being venemous has been doubted, or even disapproved by the paleontologists. [[File:
