Q: Which dinosaur had the most poisonest body? -sonu_can
A: It is very unlikely that any dinosaurs actually had poison bodies, but it is possible that they used some kind of venom to kill their prey. There is very little evidence to suggest that poison was ever used, and most paleontologists remain unconvinced that they did. Dilophosaurus spitting poison in Jurassic Park was completely made up by the creators of the movie (as was the frill).
However, a couple theropod dinosaur tooth fossils have shown a groove in the tooth that could have been used to secrete poison. The modern day komodo dragon releases venom with its bite, and it is possible that dinosaurs could have done the same.
