Pterosaurs had far more diverse wing shapes than scientists previously knew
Pterosaurs ruled the air long before birds did, and over more than 100 million years they grew into everything from small fliers to giants with wingspans above 10 meters. That range should have produced a striking variety of wing designs. Instead, modern scientific reconstructions often make them look oddly alike. That mismatch sits at the center of a new study led by the University of Bristol, published in Paleobiology. The analysis argues that commonly published pterosaur wing reconstructions capture far less diversity than would be expected for animals that varied so much in size, ecology, and flight style. No pterosaur fossil preserves a perfectly clear, undistorted full wing shape, which helps explain the problem. Some fossils preserve parts of the flight membrane, but none show the whole wing spread out in a way that settles the debate. As a result, scientists have had to build reconstructions from bones, limited soft-tissue evidence, and educated judgment about where membranes attached to the body and legs. That has left major room for disagreement. Pterosaurs were the first group …
