A holistic look at dinosaur biology (funny that - does what it says on the cover) and seems comprehensive - skeletal, locomotion, soft tissue etc. Brusatte seems to be at the forefront of current dinosaur writing, I've got some of his more popular works. This book is for the dinosaur enthusiast, not for those with a general or passing interest. Good that it is 2012 publication - dinosaur knowledge develops apace and those of us who've spent decades in their thrall need to keep our fingers on the pulse. I guess it's undergrad level, but accessible for anyone with a love of dinosaurs who has picked up anatomical awareness along the way, and Brusatte explains technicalities as he goes and eschews hard core bone morphology descriptions unless they really are necessary to the point in hand. Good range of graphics to illustrate discussion points, and still room for a few colour plates. Ideal for me.
