An extinct species of flying reptile related to the <a href="https://www.thenationalnews.com/world/2022/03/01/tyrannosaurus-rex-may-have-had-a-speedier-relative-study-claims/" target="_blank">dinosaurs</a> had colourful feathers that may have been used in mating rituals long before the evolution of birds, according to new research. The microscopic examination of a fossilised skull of a pterosaur has raised the prospect that the origins of the first feathers were some 250 million years ago — 100 million years earlier than previously thought, according to a paper published in the journal <a href="https://www.nature.com/articles/s41586-022-04622-3" target="_blank"><i>Nature</i></a>. Pterosaurs — more commonly known as pterodactyls — comprise more than 100 species of flying reptiles with leathery wings that lived throughout the age of the dinosaurs. They were wiped out at the same time during a mass extinction 66 million years ago when an <a href="https://www.thenationalnews.com/world/2022/02/23/asteroid-that-wiped-out-dinosaurs-hit-northern-hemisphere-hardest/" target="_blank">asteroid struck Earth.</a> The pterosaurs are thought to be the first creatures after insects to develop flight but there have long been questions about whether they had feathers – and what they were used for. Researchers examined 22 samples of soft tissue extracted from a well-preserved 113-million-year-old pterosaur fossil found in Brazil, identified as a <i>Tupandactylus</i>. The researchers from Europe and Brazil found two kinds of feathers on the crest at the back of the creature’s head, including a type that was structured like a modern-day bird’s feathers. They may have been used for temperature control and display, they said. They concluded that the feathers of the <i>Tupandactylus</i> originated from a common ancestor of pterosaurs, dinosaurs and birds some 250 million years ago. The earliest fossil found of a feathered bird dates back 150 million years. <i>Tupandactylus</i> had an estimated wingspan of some five metres with a huge head and skinny crest above the eyes that had a “short fuzz of coloured feathers”, according to a separate commentary on the findings by British palaeontologist Michael Benton. “Perhaps they were used in pre-mating rituals, just as certain birds use colourful tail fans, wings and head crests to attract mates,” said Mr Benton, of the University of Bristol.
