Longisquama lizard gliding. Illustration of a Longisquama insignis prehistoric lizard, showing the feather-like scales that project from its back. L. insignis lived around 247 to 201 million years ago, from the Middle to Late Triassic, in what is now Asia. One theory is that the projections on its back were used to support membranes that helped it to glide (as shown here), similar to modern gliding lizards. It is thought that this lizard may have been a precursor to modern birds.
