All of this is delivered quite convincingly and realistically by way of CGI, computer recreations of the actual "combat" scenes, charts, graphs, tables, maps, film footage of actual paleontologists and other scientists in the field, and interviews with numerous experts (principally the colorful "Dinosaur George" Blasing). The pounding, dramatic music is similar to that used for History productions like Battle 360 and The Universe, as is the macho narration (which favors overheated terminology like "crime scene," "suspect," and "investigators"). Bonus material is limited to some additional footage on one disc. --Sam Graham
