Re: speaking of velociraptors
a recent study showed that velociraptor claws would have been poor slicing blades.
A two part TV show (The Truth About Killer Dinosaurs) with one of the episodes based on this work was shown over here in August/September last year.
It was reasonably interesting but a bit dumbed down for my taste, like all recent BBC shows with any science content. The Beeb appears to have taken a policy decision not to produce science shows as such any more, rather it produces entertainment shows with a fairly minimal amount of science in them

I wish I didn't know now what I didn't know then

Re: the great Archaeopteryx hoax
name me another cold-blooded bipedal animal.
Anne Coulter.
velociraptor also has the longest arm-leg ratio of any dinosaur
To somebody like me who doesn't know too much about paleontology (would desperately love to but life gets in the way of having enough time) that's quite surprising. The obvious guess would be Tyrannosaurus rex or one of the other giant bipedal carnivores with little arms.
meaning, velociraptor evolved from an animal that could fly.
I don't know why but I just love that idea. It just shows what amazing paths the undirected process of evolution leads to given enough time.
Alternatively it shows how incredibly complex the history of life on earth is and how difficult it is for us to reconstruct it properly from the snapshots we find in the fossil record.

Oops! Wrong Planet
