Is The Armored Dinosaurs by Carpender, 2001 still the best book on Aletopelta coombsi? And is it's classifcation in Ankylosauridae still the best current understanding? Hilton (in Dinosaurs and other mezozoic Reptiles of California) double lists the fossil as both Ankylosauridae and Nodosauridae in the appendix. Thanks, Ryan Clack
