Stunning Scottish pterosaur is biggest fossil of its kind

The well-preserved find from Scotland’s Isle of Skye offers a rare peek into the evolutionary journey of these ancient wonders on wings.

A new genus of pterosaur found on the wave-battered coastline of Scotland's Isle of Skye may have had a wingspan of more than 8.2 feet (2.5 meters), in line with today's biggest albatrosses. By the looks of its bone structure, the winged reptile wasn't done growing when it died.

Some 167 million years ago over what is now Scotland’s Isle of Skye, a winged reptile, possibly as big as an albatross, soared over a subtropical lagoon, nabbing fish and squid in its toothy maw as dinosaurs thundered across the shorelines.

Somehow this reptile perished, and its carcass was quickly entombed in sediments on the bottom of that lagoon. In 2017 a chance discovery along Skye’s wave-battered coastlines revealed the resulting fossil: the best of its kind found in two centuries.

Unveiled today in the journal Current Biology, the fossil—called Dearc sgiathanach (pronounced “jark ski-an-ach”)—is spectacularly well preserved, with portions of the skull, limb bones, tail, ribs, and vertebrae still intact. The fossil joins elite company: Not many
