A colossal ‘sea dragon’ unearthed in the Midlands is being celebrated as one of the most significant discoveries in British fossil history.

The ichthyosaur, discovered at the bottom of Rutland Water, is the largest and most complete skeleton ever found in the UK, measuring an impressive 32 feet (10 meters) long with a skull weighing a ton.

This remarkable specimen, which lived around 180 million years ago, was found in England’s largest reservoir as conservationists drained water to improve the habitat for breeding birds.

Joe Davis, 48, from the Leicestershire and Rutland Wildlife Trust, who made the discovery, said: “My colleague thought the ridges we saw at the muddy bottom of the reservoir were probably just pipes.

When the palaeontologists and our team uncovered the full skeleton and lifted it out using a tractor with a loader, the head was as large as me, and I am six feet tall. It’s a tremendous beast.”

Length: 33 feet (10 metres)

Skull length: 6.6 feet (2 metres)

The ichthyosaur is believed to be a species called Temnodontosaurus trigonodon. But if it is found to be a new species, it could be named after Mr Davis.

Dr Dean Lomax, a world expert on ichthyosaurs from the University of Manchester who spent 14 days excavating the fossil, hailed it as ‘one of the greatest finds in British palaeontological history’.

He said: ‘Despite the many ichthyosaur fossils found in Britain, it is remarkable to think that the Rutland ichthyosaur is the largest skeleton ever found in the UK.

‘It is a truly unprecedented discovery and one of the greatest finds in British palaeontological history.’

Ichthyosaurs, which were marine reptiles, first appeared around 250 million years ago and went extinct 90 million years ago, varying in size from one to more than 25 metres in length and resembling dolphins in general body shape.

The remains were dug out by a team of expert palaeontologists from around the UK in August and September.

Two incomplete and much smaller ichthyosaurs were found during the initial construction of Rutland Water in the 1970s. However, the latest discovery is the first complete skeleton.

The specimen (pictured) was unearthed at the Anglian Water-owned nature reserve back in February last year during the routine draining and re-landscaping of a lagoon

‘The find has been absolutely fascinating and a real career highlight,’ said Mr Davis. ‘It’s great to learn so much from the discovery and to think that this amazing creature was once swimming in seas above us’ Pictured: the T. trigonodon fossil, showing the spine and flipper

‘Now, once again, Rutland Water is a haven for wetland wildlife — albeit on a smaller scale!,’ Mr Davis added. Pictured: a close-up of the T. trigonodon fossil, showing the bones of the flipper

The find (pictured) ‘is a truly unprecedented discovery and one of the greatest finds in British palaeontological history,’ Dr Lomax concluded

After being discovered in February last year the new specimen was removed in August so as not to disrupt the birds at the nature reserve.

Dr Mark Evans of the British Antarctic Survey said: ‘I’ve been studying the Jurassic fossil reptiles of Rutland and Leicestershire for over 20 years.

‘When I first saw the initial exposure of the specimen with Joe Davis I could tell that it was the largest ichthyosaur known from either county.

‘However, it was only after our exploratory dig that we realised that it was practically complete to the tip of the tail.’

He added: ‘It’s a highly significant discovery both nationally and internationally but also of huge importance to the people of Rutland and the surrounding area.’

Nigel Larkin, a specialist palaeontological conservator, said: ‘It’s not often you are responsible for safely lifting a very important but very fragile fossil weighing that much.

The fossil — whose skull alone was 6.6 feet (2 metres) -long and weighed one tonne — was unearthed between August–September by palaeontologists led by Dean Lomax of the University of Manchester and Nigel Larkin of Reading University. Pictured: vertebrae

‘It was an honour to lead the excavation, said Dr Lomax, who is an expert on ichthyosaurs and has described five new species in the course of his research

‘Despite the many ichthyosaur fossils found in Britain, it is remarkable to think that the Rutland ichthyosaur is the largest skeleton ever found in the UK,’ said Dr Lomax

‘The block containing the massive 2-metre-long skull weighs just under a tonne, comprising the fossil, the Jurassic clay in which it lies, and the encasing plaster of Paris and wooden splints,’ said palaeontologist Nigel Larkin

‘It’s not often you are responsible for safely lifting a very important but very fragile fossil weighing that much. It is a responsibility, but I love a challenge,’ add Mr Larkin

This is not the first ichthyosaur specimen to have been found at the Rutland Water Nature Reserve — with two smaller, partially complete fossil skeletons having been found during the construction of the reservoir back in the 1970s. Pictured: the latest excavation at the site

‘Rutland Water has a long list of previous, fascinating archaeological and palaeontological discoveries, but none more exciting than this,’ said Anglian Water CEO Peter Simpson

‘It is a responsibility, but I love a challenge. It was a very complex operation to uncover, record, and collect this important specimen safely.’

The find comes amid a flurry of interest in the reptiles, which are nicknamed sea dragons because of their large teeth and eyes.

The first ichthyosaurs were discovered by fossil hunter and palaeontologist Mary Anning in the early 19th century.

Anning uncovered the first ichthyosaur known to science aged 12 and was the subject of Ammonite, a 2020 film starring Kate Winslet.

The excavation will feature on BBC2’s Digging For Britain tomorrow at 8pm.
