| Time period : | Late Jurassic |

| Fatalities caused : | One Ceratosaurus
One Apatosaurus (Indirectly) |
- A weak bite: Allosaurus had weak jaw muscles. It had a bite force of only 200 kilograms, which is the same as a leopard's. So it was no bone crusher, like the T. rex.
- A strong skull: Despite its weak bite, Allosaurus's skull was extremely good at transmitting force along its length. With more openings and much lighter than T. rex's head, it was structured to carry tremendous levels of stress, as much as 6 tons!
This shows that Allosaurus would have used its head like a hatchet, using its strong neck muscles to ram its teeth from its upper jaw into the body of its prey. This method of attack when shown isn't pretty, nor clinical, but it's ruthlessly efficient. Allosaurus lived alongside other large carnivorous dinosaurs such
as Saurophaganax, Marshosaurus, Ceratosaurus and Torvosaurus.

Edit
Allosaurus were in the late Jurassic segment. An Allosaurus tries to attack a young Apatosaurus but the mom scares him off with her whip tail. The Allosaurus then attacks and kills a Ceratosaurus who was chasing some Dryosaurus . Then, while walking away to avoid the dry season, an Apatosaurus breaks its foot and falls down a 20 foot drop, mortally wounding it. Three Allosaurus attack it and eat it alive, killing it in time.
Errors Edit
- Allosaurus's hands couldn't pronate without breaking them.
- Allosaurus would've been smaller, at 32 feet long instead of 43 feet. It's possible the Allosaurus in the film could be representative of the much larger genus of Allosaurid, Saurophaganax, which was similar in size to the Allosaurus in the documentary. However there are controversial claims of Allosaurus reaching 40 ft/
