Tambussi CP, de Mendoza R, Degrange FJ, Picasso MB (2012) Flexibility along the Neck of the Neogene Terror Bird Andalgalornis steulleti (Aves Phorusrhacidae). PLoS ONE 7(5): e37701. doi:10.1371/journal.pone.0037701
Since both my scenario of bite, grind and pull and the hammer blow hypothesis both rely on extensive, dynamic, and robust neck musculature I can't really say that this work supports either notion more strongly.
What I did find of interest was the one comment someone left in the comment field for this PLoS ONE paper:
Well RobertoS, as you made the connection between Allosaurus/theropods way back on October 11, 2013 looks like you beat me to the punch a bit :^) .... Just add the serrated tongue/choanal papillae and stress reducing headgear and it's complete!!
Furthermore the authors responded to this valid point and question with.... nothing!! Seriously what is with writers/researchers not fielding the questions that someone who took the time and energy to write on your very own published work - and probably had to go through the hastle of getting a PLoS ONE account. Say what you will about blogging but it is a living, breathing, responsive media.
