A mystery sea creature was found washed up on a British beach – baffling experts as to what it may be.
The five-ft long carcass of the alien-like creature was discovered washed up on sand by dog walker Beth Jannetta, 41.
Ms Janetta snapped the mystery monster – which has a long head, giant jawline and slender tail – and passed on her pictures to experts.
The five-ft long carcass of the alien-like creature was discovered washed up on sand by dog walker Beth Jannetta, 41 on Rhossili Beach, Gower – and has baffled marine experts
But marine boffins are unable to identify the creature – but say it could be a type of whale, dolphin, or porpoise.
Ms Jannetta, who found the skeleton on Rhossili Beach, Gower, said: ‘I was going for a run with my dogs when I came across it. It looked like a well rotted cetacean to me.
‘Other people think it is something different, like a crocodile.
‘It would be very interesting to find out what species it is.’
Bioscience expert Dr Dan Forman said: ‘When you look at it the first time you may think it is a crocodile, but it is certainly not. There is a big bulge on the base of the skull which is characteristic of a cetacean.’
Dr Forman, of Swansea University, added: ‘It’s jawline suggests it is like a cetacean whale or a dolphin.
‘We get a reasonable amount of whales and dolphins, a lot which are dead and decomposed in places like Pendine and Rhossili.
‘From the data around carcasses washed up, there seems to be a cluster this time of year around June and July.
‘The jaw is thin in places and it looks from the picture like it is upside down.’
Mark Hipkin, National Trust area ranger, who was called to collect the body, said he thought it was a porpoise.
He said: ‘We have porpoises washing up quite regularly, as well as dolphins and seals and sometimes sheep.’
