Velociraptors likely had venomous fangs

As if volociraptors weren’t already terrifying enough with those massive claws, a top speed of 40 mph and up to 80 menacing teeth, it seems some of those teeth injected prey with venom. (Wired)

How do we know? Researchers have found tooth and skull structures “analogous to the venomous morphology of lizards” in the sinomithosaurus group of dinosaurs (which includes velociraptors). And like modern lizards, the venom “probably wasn’t lethal, but instead shocked prey into immobility.”

Thank you for making my own students have access to your blog
post. Your kindness is usually greatly appreciated.

I've got some ongoing initiatives and I wanted them to assist me with it.
The only way they were able to do this was carry out some exploration on tthe internet so as
to help to ake my work faster. The students camme across our site as well as the content on it, particularly this blog post, reallpy hslped them to get good conclusions on what we needed to do.
Of course, I will still vissit the site for brand new updates on this top
and other issues interesting.

Pound360 Archive

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
