This book doesn't include any mention of the Pipestone Creek bone bed near Grande Prairie. It's one of the richest dinosaur bone beds in the world, and several new species have been discovered there, and in other smaller deposits in the area. The bone bed was discovered in 1972 and has been the site of active excavation since 1973. If they leave that out, what else are they ignoring? It's an extremely bizarre omission if they did any research at all.
