The news was out earlier this week.
Crichton's depiction of Dilophosaurus wetherilli and Procompsognathus triassicus may once be considered unorthodox (if not naive), but things seem to have changed: "In Sinornithosaurus fossils, researchers discovered an intriguing pocket, possibly for a venom gland, connected to the base of a fang by a long groove, which likely housed a venom duct, the study says. Sinornithosaurus fangs also feature snakelike grooves in their surfaces."
Much like a cobra's or a boomslang's, huh? David Burnham says S. millenii (which translates to "Chinese bird lizard of the millenium" in English) probably produced a type of neurotoxin that was potent enough to stun birds and other small animals into lethargy at the amount Sinornithosaurus was probably capable of producing.
I couldn't agree more. Now I think at least some other species of dromaeosaurs produced saliva that acted like neurotoxins. The spit would also cause stupor. Honestly, a pack of Utahraptor would find it easier to climb and dispatch a groggy Astrodon than a fully alert one.
WATCH OUT WORLD! DROMAEOSAURS JUST GOT EVEN DEADLIER!!!
