Weigeltisaurids: Earth's first gliding vertebrates
Original: Weigeltisaurids: Earth’s first gliding vertebrates
Weigeltisaurids, small Permian-era reptiles with sail-like wing membranes supported by elongated bony rods, are being described as Earth's first gliding vertebrates, predating pterosaurs, birds and bats by tens of millions of years. New coverage highlights their unique skeletal adaptations for aerial locomotion and what their fossils reveal about the early evolution of flight-like behaviour in vertebrates.
Why now: New science coverage is drawing attention to these ancient reptiles' role as the earliest known gliders.
