![]() Walking like a dinosaur
The BBC goes back in time
By BBC News Online's Damian Carrington
The making of a landmark new BBC TV series, Walking with Dinosaurs, has given palaeontologists a remarkable new view of how the extinct creatures roamed the Earth.
Until now, said Dr Norman, palaeontologists have reconstructed skeletons. This knowledge was used to construct the animatronic models used in the BBC series, which will be shown in October. But when the dinosaur's movements were tested, they were not entirely life-like and so subtle twists and changes had to be made to the feet and ankles, fingers and wrists. The making of the programmes also used computerised animation software, similar to that used in the making of Jurassic Park. Sagging bodies "I had no idea how useful the commercial software would be," said Dr Norman, who was speaking at the British Association's Festival of Science in Sheffield, UK. "I'm now pretty jealous of the workstations the animators use." The computer animation helped create finishing touches to the realism of the creatures, from fluttering trailing edges on the wings of flying reptiles, to dinosaur bodies sagging and skin wrinkling as the creatures move.
Also at the festival, Professor Kevin Padian, described how not all dinosaurs are extinct. Birds are now being seen as the descendants of the dinosaurs, not reptiles, he said. This realisation enables palaeontologists to work backwards through time to try to understand better how birds evolved. He believes that feathers did not originally evolve for flight. They certainly would have provided some insulation, possibly to keep eggs warm, he said. But as the colour of the first feathers is not known, it cannot be ruled out that they were used for camouflage, display or species recognition purposes. Here are some of the images taken from the series. ![]() ![]() ![]() ![]() |
