restoration


the skeleton preserved in dorsal view , largely complete, bones still articulated , impressions of of integument. part of pectoral girdle missing , part still encased in stone.


in 1987, gans et al. published revised description: found patagium did not extend forelimbs. experiments models showed reptile glide uropatagium , stabilize glide changing angles of forelimbs provide aeronautic canard or bending tail or down produce drag.


in 2006, dyke et al. published study on possible gliding techniques sharovipteryx. authors found wing membrane, stretched between long hind legs , tail, have allowed glide delta wing aircraft does. if tiny front limbs supported membrane, have acted efficient means of controlling pitch stability, aeronautic canard. without forewing, authors find, controlled gliding have been difficult. canards on forelimbs, these anterior membranes may have formed excellent control surfaces gliding. area around forelimbs prepared away in known fossil, destroying possible trace of membrane there.
