LONDON: Sir David Attenborough has described the painstaking efforts of excavating the skull of a sea monster as part of a new documentary, reported German news agency (dpa).
Attenborough and the Giant Sea Monster follows the process of removing the huge skull of a pliosaur, one of the biggest carnivorous creatures the world has ever seen, from the Jurassic Coast, in southwest England’s Dorset.
It also uses computer-generated imagery (CGI) to show what the giant predator, which was the size of a London bus, would have looked like when it terrorised the seas in the time of the dinosaurs.
Attenborough said: “It (the skull) weighs over half a tonne. That’s a pretty heavy thing to handle. Now, you have to get it out from half way up the face of a tall cliff which itself is crumbling away, and if you drop it and break it, it is a major catastrophe. I mean, you will have lost a lot of information.
“So, the problem we see in the first part of the programme was about is how on earth do you go around getting this out?”
“There is no question about that. (It’s) one of the biggest skulls you’ve ever seen. I mean, it’s huge and so, although I was aware of the tip that was first discovered, I hadn’t fully appreciated how big the whole head would be and it’s enormous.
“So sheer scale was what first impressed me. The thing about the skull is that it’s not only by far the most informative part of the body, it is by far the most delicate, too. And it’s the detail, and that is so rare to find it. And this is as near perfect as it can possibly get.
“It could obviously move at great speed and the teeth that were found in the tip of the skull have vertical ridges down them, which break the suction and allow it to withdraw the jaw from prey quickly – that’s the sort of deduction that we’re able to make and which we show in the programme.”
The documentary reunites Attenborough with his long-time executive producer, Mike Gunton, with whom he has worked on the Planet Earth series, and he said Gunton was his first call when he learned of the discovery of the skull.
“I’ve been passionate about collecting fossils since I was a kid and I’ve never given it up. In consequence, I know a number of the collectors and people who live on the Jurassic Coast.
“One of them, Chris Moore, is a long-time friend, and he got in touch with us and said there’s going to be a remarkable discovery that this thing had been found.
“I immediately rang up Mike and said, ‘We ought to be doing this’. Fortunately, the BBC was able to do so – when the BBC decides that it wants to act, it can act very swiftly and very effectively. And we had a crew down there before you knew where you were.
“It looked as though it was going to be one of the most complete skeletons ever found. The head was only part of it, and that was up in the cliffs. And the body itself, being about the size of a London bus, extends into the cliff.
“The decision had to be taken that we would go for the skull because that is where all the information lies.
“The rest of it probably has to be there but it’s 30, 40 feet long (nine to 12 metres long), so at the moment, we are concentrating on the head, the skull, the most important part.”
Attenborough said he hopes the programme encourages children to embark on adventures to make prehistoric discoveries – as long as they take the proper precautions.
“I think there are still going to be little 10-year-olds and 12-year-olds going around on bicycles hitting rocks with hammers.
“Put on glasses – it’s very dangerous. I mustn’t encourage children, they must wear eye protection. But kids that are being born today will still find that romantic, and not only kids… I thought I was going to be a palaeontologist at one stage, but I was thwarted.”
Attenborough and the Giant Sea Monster will air at 8 pm (2000 GMT) on Jan 1 on BBC One and iPlayer in the UK. – BERNAMA-dpa
