Interesting topic! I wonder what we think about this .

A rather ‘interesting’ new paper in Biological Reviews claims that:
‘Hands evolved to punch faces. Faces evolved to take punches. That’s the hypothesis being bandied about by University of Utah researchers Michael Morgan and David Carrier, the pair proposing that the apparent “protective buttressing” of our skulls and hands is a sign of violent prehistoric fights where fists of fury dictated who would mate and who would exit the gene pool.’
Nice critique of the paper can be found here: http://phenomena.nationalgeographic.com/2014/06/10/our-skulls-didnt-evolve-to-be-punched/
And the original paper here: http://onlinelibrary.wiley.com/doi/10.1111/brv.12112/full
Cool paper by Marcelo Sanchez-Villagra and colleagues.

Wow!!

Subject: Not dinosaurian but maybe of interest
I guess the message here is “Don’t look a gift leatherback turtle in the mouth.”

Scientists have discovered a freakish, birdlike species of dinosaur — 11 feet long, 500 pounds, with a beak, no teeth, a bony crest atop its head, murderous claws, prize-fighter arms, spindly legs, a thin tail and feathers sprouting all over the place. Officially, it’s a member of a group of dinosaurs called oviraptorosaurs.
Unofficially, it’s the Chicken From Hell.
