First known venomous dinosaur found

The first ever known venomous dinosaur has been discovered, a fearsome feathered predator that lived 125 million years ago.
Sinornithosaurus millenii was a small dinosaur the size of a turkey however its bite would have proven a death sentence to any animal unfortunate enough to be at the receiving end of its paralysing poison.

Scientists believe that the species could be vital in the understanding of how the use of venom by predators evolved and how it came to be used by modern day snakes and other creatures.
A feathered predator that lived 125 million years ago has been revealed as the first-known venomous dinosaur, which paralysed its prey with poison in a similar way to some snakes.

Not all dinos necessarily evolved into birds, especially not the quadropeds. Very true, I doubt a twenty or so ton sauropod turned into the sparrow sitting on my porch. But the dinosaur in question, Sinornithosaurus, is thought to be one of the dinosaurs that gave rise to birds.

Besides, there is no need for venom to hunt by poisoning,like the Komodo dragon(Varanus komodoensis) that kills by a bite too,but does not leave venom but a nasty mixture of microbes that cause a sepsis in the prey,once it died of the fever the dragon has a nice feast. Oooh, but Komodo dragons do have venom, it transpires.

What do you know? There is actually a bird that is poisonous to eat. Not necessarily a "venomous bird", but the supposed venom from the Sinornithosaurus wasn't necessarily potent.

Oooh, but Komodo dragons do have venom, it transpires. Still,their bigger prey dies of sepsis, not of venom.

A feathered predator that lived 125 million years ago has been revealed as the first-known venomous dinosaur, which paralysed its prey with poison in a similar way to some snakes.Sinornithosaurus millenii, a dinosaur about the size of a turkey, had grooved fangs for channelling venom and a pocket in the upper jaw that probably held venom glands, scientists have discovered.

Ive read this news before.Very interesting about Sinornithosaurus millenii.Dilophosaurus was shown as a venomous dinosaur in Jurassic Park.But it is not proved that it is venomous.

Ive read this news before. I'm not surprised, I've already merged 2 threads on this subject. I will merge this one too.

Unless their is a bird out there with a similar trait that I have never heard of, I must be somewhat skeptical of this claim. Amazing find, but rather peculiar. I am skeptical as well. In todays world I do not know of a single venomous bird. Either this was an adaptation that didn't work and was therefore worthless for being carried on in the genus or this little birdie became extinct or maybe both, who know.
