"The fossil remains of this species have been found only in the Solnhofen limestone of Bavaria, Germany, dated to the late Jurassic Period (early Tithonian), about 150.8\u2013148.5 million years ago.[2] Like all pterosaurs, the wings of Aerodactylus were formed by a skin and muscle membrane stretching from its elongated fourth finger to its hind limbs. It was supported internally by collagen fibres and externally by keratinous ridges."@en . "Aerodactylus"@en .
