anthemaniac writes "A reptile that lived 225 million years ago had triangular-shaped wings like the delta-wings of some jets. At least that's what a new computer model suggests. Researcher have generated several possible shapes for the wings of Sharovipteryx mirabili before, so this is just the latest guess (based on one fossil). Last fall NatGeo reported that the first biplane configuration was on a dinosaur. Maybe airplane designers should delve into the fossil record a little more."
