Sciurion campestre, a new genus and species of “flying squirrel”, from the Cypress Hills Formation of southwestern Saskatchewan, is distinct from known North American and European Petauristinae. The fauna with which it is associated indicates a Hemingfordian age. This “flying squirrel” is the oldest known from the Great Plains of North America.read more

Flying squirrels are monophyletic.
TL;DR: It is shown that gliding evolved only once among squirrels and that the flying squirrels are a monophyletic group, and the manner of attachment of the patagium to the forelimb is different in each and demonstrates five morphologies differing from that of flying Squirrels.
