This is very belated, but back in the summer of 2014 I was approached to write a bunch of sections — all of them to do with dinosaurs, naturally — in the book Evolution: The Whole Story . I did seven group overviews (Dinosauria overview, prosauropods, sauropods, stegosaurs, ankylosaurs, marginocephalians, and hadrosaurs), having managed to hand the theropod work over to Darren.
