I really did enjoy this book, and all the discussions about what we can glean about dinosaur habits by their trace fossils. The writing style was lively and engaging.Possibly, though, this is not the end-all book on this subject matter. As I recall, the author teaches paleontology but doesn't collect fossils himself, and thus there seem to be definable limits to his knowledge. Specifically, he states we don't have trackways attributed to several varieties of dinosaurs, mostly just theropods, hadrosaurs, and sauropods.Yet other books on my "reading list" have asserted that indeed we do have tracks attributed to ceratopsians, ankylosaurs, etc. It's just that these tracks might be located in far-flung locations that are difficult (and expensive) to reach in person. But as far as other researchers are concerned, these tracks do exist.So enjoy the book -- it is very much worth reading. But then keep reading other books on paleontology to perhaps get other perspectives on the topic of ichnology.
