Feb 22 – A fossil jawbone peeking out from a limestone seashore on Scotland’s Isle of Skye led scientists to discover the skeleton of a pterosaur that showed that these remarkable flying reptiles got big tens of millions of years earlier than previously known.
A handout illustration shows the newly identified Jurassic Period flying reptile, or pterosaur, called ‘Dearc sgiathanach’.Dearc weighed very little – probably below 22 pounds – thanks to its hollow, lightweight bones and slender structure, said University of Edinburgh paleontology doctoral student Natalia Jagielska, lead author of the research published in the journal Current Biology.
Pterosaurs are some of the rarest vertebrates in the fossil record owing to their fragile bones, some with walls thinner than a sheet of paper. “In the Cretaceous, some pterosaurs got enormous. These were some of the most superlative animals that ever lived. Dearc was not close to them in size or grandeur, but it was 100 million years older. Evolution needed time to make such giants,” University of Edinburgh paleontologist and study co-author Steve Brusatte said.
