Re: Sinornithosaurus venom
I was surprised that Gong et al didn't mention the five extant
species of poisonous birds, the Pitohuis, the Ifrita, and the Rufous
Shrike - Thrush. Pitohui, apparently, takes up batrachotoxin by
feeding on toxic beetles. The toxin is shed in the powder down, and
it can apparently cause contact dermatitis just by handling the
At least these are examples of archosaurs that secrete poison.
Well, they secrete it, but they don't produce it -- as some of the
"papers that cite this article" show. They take it up from their food
and deposit it in their feathers, skin, and elsewhere -- just like the
frogs do that use the exact same poisons.
