Comment on Sinornithosaurus by Fafnirx

Which organ is unsure. Some of the hypotheses that the animal was venomous are flawed anyway. The proposal that the teeth of Sinornithosaurus were abnormally long has been disproved, as they had actually come out of their sockets, a common feature of crushed and flattened fossils. It is also impossible to verify the supposed presence of venom glands, and people attempting to find them found only the normal sinus chambers of the skull. You see, the bad condition of the skull, along with a lack of evidence for venom glands, lowers the possibility that the animal was venomous.
