A skull and part of the skeleton of a dinosaur has been found at the site of a prehistoric forest in north East China.
The dinosaur had teeth that are like teeth of rear-fanged snakes and venomous lizards.
Some of the fang like teech which are on the upper jaw had grooves that scientists think poison ‘flowed’ through.
So this dinosaur may killed its prey by poisoning it.
The dinosaur that was found is a feathered raptor.
It was about the size of a turkey and 128 million years ago it preyed on birds using its fangs.
A bird with a bite that delivers poison. I wonder why it died out.
