Kuehneosauridae is an extinct family of small, lizard-like gliding diapsids known from the Triassic period of Europe and North America.

[4] The oldest and most primitive known member is Pamelina from the Early Triassic (Olenekian stage) of Poland, which already has vertebrae with characteristics consistent with gliding or parachuting.

Weigeltisaurids ("Coelurosauravidae") that lived as long ago as the Late Permian also had bone-supported membranous wings.

But the anatomy of these groups is too different to consider them close relatives, although both weigeltisaurids and kuehneosaurids belong to diapsid reptiles.
