As another reviewer has already mentioned, "Allosaurus: A Walking with Dinosaurs Special" (hereafter "Allo") is essentially the seventh episode of that magnificent pseudo-documentary series, and maintains that series lofty production and narrative standards (including retaining Kenneth Branaugh as solemn narrator). I think "Allo" was created in response to some ineffable clamor for carnivore balance. In other words, T-rex had his own episode on "Walking with Dinosaurs"; now it's Allosaurus's turn to shine.
The first 30 minutes of "Allo" chronicles the relatively short but painfully eventful life of an Allosaurus, christened "Big Al". We follow his life from a tiny hatchling to a nearly full-grown subadult. He encounters stegosauruses. He participates in a rousing diplodocus hunt with others of his kind. He attempts to woo a much larger, more mature,and definitely more ferocious female allosaurus. Throughout his life, BigAl was basically the carnivorous dinosaur's answer to Evel Knievel. He suffered bites, scratches, lacerations, and bone dislocations, especially to his feet and legs. The litany of injuries finally takes its toll on Big Al, eventually losing his hunting ability and succumbing to starvation and thirst.
As I was watching "Allo", I was astonished by many things. For example, how did a hatchling the size of a pigeon grow to be a 3-4 ton apex predator? Also, where did Big Al's mother get her maternal instinct, enabling her to protect her brood like a mother crocodile from predators, including, unsuccessfully, against a cannibalistic male allosaurus? How many of Big Al's nest mates survived along with him (probably not too many; allosaurus chicks, like crocodile babies, probably had a very high mortality rate)? Did Allosaurus really cooperate to take down gigantic prey like Diplodocus? Did sexual dimorphism really exist among allosaurs, meaning size differences among the sexes, in this case females larger than males? Some of these questions are addressed in the second 30-minute half of "Allo", where fossil analysis speculates upon Big Al's life and provided inspiration for the first half.
One thing stood out prominently in "Allo": Big Al and his ilk may have been at the top of the food chain during the Jurassic, but their lives were far from easy. Despite their size, allosaurs must have had a tough time against the larger herbivores. As I recall, Big Al meets two stegosauruses but decides not to attack them, probably because of their sharp spiked tails and aggressive posture. During the thrilling diplodocus hunt on the salt flats, it takes three(!) allosauruses, including Big Al several hours to bring down even a sick, overheated member of the herd. Even after they start to consume the multi-ton carcass, a bigger female allosaurus arrives and threatens to claim the kill as her own. Speaking of females, Big Al's clumsy attempt to woo a female allosaurus literally ends in crushing failure. Most importantly, an allosaurus's feet and legs were its fortune; any serious damage to either could spell doom. Big Al breaks one of his middle toes while chasing one of the bipedal, relatively small Dryosaurs - a fatal wound for any hunter, but especially a two-legged one.
Both halves of the "Allo" disk provide intriguing scientific, paleontological, and zoological information about Big Al and his world. Of course, some of this information is speculative, which may put off some viewers, just as it may have done with the "Walking..." series. Also, a few viewers may disapprove of giving a dinosaur a name, as if he were a harmless pet, because it may lessen his dignity. Phffft! I think chances are you will enjoy learning about Big Al's life and death in "Allo". After all, T-rex has had enough press.
