This shape allows the squirrel to overcome any detrimental rotational momentum that it might have generated during take-off. It also has large brown eyes. The fungi mycelia are thought to be highly beneficial for tree growth and maintenance due to association with tree roots. The scansoriopterygid dinosaurs Yi and Ambopteryx had rather elaborate, superficially bat-like patagia in the forelimbs, unique among dinosaurs.
