Delta-wing reptile

LiveScience points out a fossilised reptile which apparently used a delta-wing structure to fly.

Sharovipteryx mirabilis was known as having a flight system dominated by its hind legs, but as it turns out, there were two sets of wings attached, one dominating front & one dominating the rear limbs.

Delta wings are good for fast flight, specificially supersonics, but nobody here claims a supersonic lizard (which would be a tad scarey, particularly if larger ones existed), just that its flying attitude would have been literally nose-high plus steep descent, & that the second set of wings would have assisted it in adjusting its pitch (angle of “attack”) as it flew.
