 However, the body feathers of "Epidexipteryx" are unique in that some appear to arise from a "membranous structure" at the base of each feather.It has been suggested that this may represent a stage in the evolution of the feather.In all, the skeleton of "Epidexipteryx hui" measures 25 centimeters (10 inches) in length (44.5 cm or 17.5 in including the incomplete tail feathers), and the authors estimated a weight of 164 grams, smaller than most other basal avialans.
