Set at the beginning of the Cretaceous period this one-off Walking With Dinosaurs special features zoologist Nigel Marven in search of an Argentinosaurus, the biggest dinosaur that ever lived, and a Giganotosaurus, the awesome predator that hunted it.

Filmed in the Canary Islands on Tenerife and Frasier Island, Australia, we made a pneumatically controlled Sarchosuchus head that lept out of the water to strike at Nigel Marvin and a 10th scale miniature skeleton of a Argentinosaurus.

We also supplied a Pteranodon animatronic head as well as eggs and other bones as props.
