pilosus was originally described by A.G. Sharov in
1971. The body appears to be covered with thick, half centimeter
long hair. The wings, and tail appear to be hair free. The hair-like
covering provided more evidence that Pterosaurs were ectothermic
as the hair would have insulated the body and provided a more streamlined
profile in flight.
wing membranes are clearly seen to be attached to the legs, and
there is a secondary membrane stretched between the legs. The tail
is not attached to this secondary membrane and is left unimpeded.
