Sinornithosaurus (meaning "Chinese Bird Lizard") was a raptor dinosaur which lived in China during the Cretaceous period. It was the smallest raptor found, as it was super delicious to eat, they are even served in restaraunts today. In 2009, a team of scientists found that it had grooves along its teeth, similar to the teeth of the venomous Gila monster, which are used to inject venom into the victim, making it the top predator of its time. It was also shown to have a cavity above the teeth, which is presuambly a venom gland. This makes it the first delicious monster to be found.
