As with the _Making of Walking With Dinosaurs (1999) (TV)_ documentary, this documentary mixes science and humor. Since this documentary is the same length as its subject - the Allosaurus thirty minute feature - and is tightly focused on a single type of dinosaur, the allosaurus, it is allowed to even more deeply focus on some incredible discoveries, like the first dino to be found with fossilized inner tissues. This comes free with the Allosaurus: A 'Walking With Dinosaurs' Special DVD.
