A new species of dinosaur that had an “eye-catching sail” along its back has been named after sailor Dame Ellen MacArthur.<\/p>\n

The dinosaur, unearthed on the Isle of Wight, has been given the name Istiorachis macarthurae with the first word meaning “sail spine” and the second referring to Dame Ellen’s surname.<\/p>\n

The record-breaking round-the-world yachtswoman said it was a “huge honour”, adding: “The fact that the Istiorachis ‘sail’ could be likened to the sails I have spent so much of my life below was very touching.”<\/p>\n

After being analysed it has now been officially named and described by island-based scientist Jeremy Lockwood, and is now on display at Dinosaur Isle Museum in Sandown.<\/p>\n<\/div>\n

The medium-sized herbivore once roamed the floodplains of what is now the island’s south-west coast.<\/p>\n

Its remains, which date back 125 million years, were originally discovered by fossil hunter Nick Chase<\/a>, who died of cancer in 2019.<\/p>\n

Before Dr Lockwood’s analysis the fossils were assumed to have belonged to one of the two known iguanodontian dinosaur species from the Isle of Wight.<\/p>\n

He said: “While the skeleton wasn’t as complete as some of the others that have been found, no-one had really taken a close look at these bones before.<\/p>\n

“It was thought to be just another specimen of one of the existing species, but this one had particularly long neural spines, which was very unusual.<\/p>\n

“It may have been used for display, much like a peacock’s feathers, possibly to attract mates or intimidate rivals.”<\/p>\n

For the study, researchers compared the fossilised bones with a database of similar dinosaur back bones which allowed them to see how these sail-like formations had evolved.<\/p>\n<\/div>\n

Dame Ellen MacArthur, who is from Derbyshire, said it was “both extraordinary and a huge honour” to have the dinosaur named after her<\/figcaption><\/p>\n<\/figure>\n

Dame Ellen, founder and patron of the East Cowes based charity the Ellen MacArthur Cancer Trust, said: “It is certainly not an everyday occurrence to be asked if a newly discovered dinosaur could reference your name in its title.<\/p>\n

“I was somewhat taken aback when this conversation began, but felt hugely privileged to be asked. <\/p>\n

“The fact that the Istiorachis ‘sail’ could be a-likened to the sails I have spent so much of my life below was very touching.<\/p>\n

“It is both extraordinary and a huge honour that a creature living 125 million years ago could possibly be linked to my family name.”<\/p>\n

She became the fastest person to sail solo non-stop around the world in 2005.<\/p>\n<\/div>\n<\/div>\n
