Sinornithosaurus, a raptor with bird-like features, was discovered in China in 1999. Recently researchers have been examining the remains in more detail, and have figured out that these dinosaurs most likely had a system for injecting poison into their prey. There are grooves in their teeth and a duct running along the base of the teeth. A small cavity in the skull would have been the spot where a venom-producing gland was held, which then fed poison into the ducts and down the teeth. The raptor mostly likely held its prey for awhile until the poison was able to immobilize it, then feasted on whatever it had caught.
