investigator have reconstructed a pernicious Jurassic sea monster after dig an tremendous fossilized pliosaur skull from a U.K. drop face .
The discovery of the skull and subsequent reconstructive memory are play up in a new documentary , " Attenborough and the Jurassic Sea Monster , " which air Wednesday ( Feb. 14 ) on PBS .
The fossilized skull pulled from the cliff is one of the biggest and most complete pliosaur skulls ever discovered.
The pliosaur — a group of heavy , carnivorous maritime reptiles — and would have been over 30 fundament ( 9 meters ) long , with jaw full of vast , razor - crisp teeth . Pliosaurs lived 150 million yr ago , when global temperatures were far higher than they are today , with sea that were " quick , shallow and teeming with animation , " David Attenborough said in a cartridge holder from the show . They were the large ocean vulture of theJurassic period(201.3 million to 145 million years ago ) .
" The fauna would have been so monumental that I think it would have been able-bodied to predate in effect on anything that was unfortunate enough to be in its space,“Andre Rowe , a research worker in the School of Earth Sciences at the University of Bristol in the U.K.,told the BBC . " I have no doubt that this was sort of like an underwaterT. male monarch . "

The fossilized skull pulled from the cliff is one of the biggest and most complete pliosaur skulls ever discovered.
In 2022 , fossil enthusiast Phil Jacobs was walking along a beach on England’sJurassic Coastwhen he noticed a bit of snout puzzle out of the drop . He contacted his admirer Steve Etches , a paleontologist and fertile fossil collector , and the pair carried the dodo to safety .
But Etches think more of the pliosaur was mesh inside the drop , so he and his co-worker turn up and removed the rest of the 6.5 - groundwork ( 2 m ) skull . They took roughly three week to unearth the skull from a sheer cliff facial expression while freeze 50 feet ( 15 m ) above the ground .
" It was by far the most difficult , back - breaking and draining jibe I have ever act upon on , both physically and mentally , " Etches told Live Science . finally , they successfully hit it , and it turned out to be one of the bad and most perfect pliosaur skull ever found .
Pliosaurs were top predators of oceans in the Jurassic era, able to hunt anything they came across.
Meanwhile , experts at Imperial College London set about reconstructing this Jurassic predator . research worker eff the ocean monsters had short , boneheaded necks and four solid flippers to actuate themselves at high amphetamine , but how these work out together was unclear .
Luke Muscutt , a lab technician at Imperial College London who had been build a robotic plesiosaurus — the group of marine reptiles that pliosaurs belong to — as a cacoethes task , build the prototype to show how these extinct reptile might have act . " We found that plesiosaurs used a tandem flipper propulsion system , imply the four flippers put to work together to push them through water , " hesaid in a statement .
" This system is unique , because all other animals with flipper , like penguins and turtle , only use the front two for actuation and the back flippers or feet for guidance , " he enunciate . " We studied this by building a tandem flap flipper system mounted on a gauntry , without a head or tail . " Body plates and prosthetic " hide " were then added to the automaton to finish the Reconstruction Period .

Scientific inquiry is now being carried out on the pliosaur ’s skull to learn more about the extinct animate being , Etches said . " It gives us a more in - depth aspect at the individual bones and anatomical structure of a pliosaur skull — joint and suture parentage , which have n’t been previously go through before due to its exceptional preservation , " he said .
Etches is also now planning the next phase of excavation in the hope of regain the relief of the fossilized body . " I game my lifetime [ that ] the rest of the beast is there , " he tell the BBC . This part of the drop-off line is going back by foot a year . And it wo n’t be very long before the rest of the pliosaur drops out and gets lost . It ’s a once in a life chance . "
