"...presents a diverse array of original research on numerous dinosaur taxa, provides an excellent source of references, and is abundantly illustrated...succeeds in 'developing a better understanding of dinosaurs as biological species' (p. 309) and provides solid empirical evidence for ontogenetic and dimorphic variation in a broad range of dinosaurs." Sandra J. Carlson, GSA Today "...contains many stimulating contributions and some of them (e.g. Chapter 18) are the best examples of the...palaeontological problems and frustrations...should be accessible at any reference library." Makoto Manabe, Geological Magazine "...does contain a number of useful contributions to dinosaurian systematics that will be of interest to every serious student of this topic. It should encourage all researchers to pay more attention to the historically neglected problem of morphological variation in non-avian dinosaurs and to adopt explicitly cladistic approaches for sorting our dinosaurian interrelationships." Hans-Dieter Sues, American Paleontologist "...a collection of papers on all aspects of dinosaur reproduction and development for the professional reader and advanced student...this long-awaited book sets out to review and summarize today's knowledge of one of the most exciting areas of dinosaur studies...The work is an essential addition to the dinosaur literature and is the only compact reference work covering reproductive biology."
