A Jurassic dinosaur fossil that was first noticed greater than 50 years in the past has been extracted from the bottom of a cliff on Skye and formally recognized.
The fossil was found close to to Elgol in 1973 and is Scotland’s earliest recorded dinosaur discover.
Nationwide Museums Scotland (NMS) mentioned it remained uncollected till a crew led by Dr Elsa Panciroli returned in 2018.
Often known as the Elgol dinosaur, the fossil is preserved in fragments, however consultants have recognized a part of the backbone, ribs and hipbones – making it probably the most full dinosaur skeleton discovered to this point in Scotland.
Bone evaluation has led researchers to imagine it’s an ornithopod dinosaur, a bunch which incorporates notable later dinosaurs comparable to Iguanodon, Parasaurolophus and Edmontosaurus.
It’s believed to this point from round 166 million years in the past, within the Center Jurassic, making it one of many oldest recognized ornithopod physique fossils, from a bunch of dinosaurs that grew to become much more distinguished within the later Cretaceous interval.

Dinosaur finds are uncommon in Scotland and far of the rock that’s uncovered on the floor throughout the nation shouldn’t be from the interval when the animals dominated the earth – the Triassic, Jurassic and Cretaceous intervals, collectively often known as the Mesozoic period. Dinosaur finds are extra frequent in southern England the place extra of the uncovered rock is geologically newer.
Evaluation of the bone construction signifies the Elgol dinosaur, which might have been roughly the dimensions of a pony, was not less than eight years outdated.
The brand new description of the dinosaur is revealed within the Earth and Environmental Science Transactions of the Royal Society of Edinburgh.
Lead writer Dr Panciroli, Pure Setting Analysis Council (NERC) impartial analysis fellow at NMS, mentioned: “This was a very difficult extraction.

“In fact, we’d previously felt it was too difficult to collect the fossil, but I thought it was really important to study it.
“I used to be capable of persuade the crew to present it a strive. It took quite a lot of onerous work from lots of people, however we did it: lastly we will affirm and publish Scotland’s first recorded and most full dinosaur, and that makes all of it worthwhile.”
The excavation was made doable with the assist of a specialist crew from Analysis Casting Worldwide, primarily based in Canada, whereas a crew from Elgol’s Bella Jane Boat Journeys piloted the inflexible inflatable boat and dinghy to the shore on the foot of the cliff, the place the specimen was loaded and brought again to port.
Different Jurassic discoveries from Skye embrace descriptions of grownup and juvenile mammals of the identical species, Krusatodon, which revealed the animals grew extra slowly than the mammals of in the present day, and the world’s largest Jurassic pterosaur (flying reptile) fossil, Dearc sgiathanach.
Tons of of dinosaur tracks have additionally been found throughout Skye lately.

Dr Stig Walsh, from NMS, mentioned: “This is a wonderful addition to the rapidly growing set of Jurassic finds from the Isle of Skye which are enabling us to learn more and more about the rich ecosystem of the time.
“We have recognized there have been dinosaurs there for some time, most clearly from the well-known footprints at An Corran, Brother’s Level and Duntulm and from particular person bones, nevertheless it’s thrilling to see a extra full, if nonetheless partial, skeleton.
“We’re delighted to add it to the other amazing finds now in the national collection.”
The earliest scientifically described dinosaur discover within the UK was in Oxfordshire within the mid to late seventeenth century – a now-lost piece of bone from the Megalosaurus. Nevertheless it wasn’t till the early nineteenth century that after one other discover from the identical animal in the identical space, the Megalosaurus was the primary dinosaur to be named, based on the Oxford Museum of Pure Historical past.
