New pterosaurs for The Big Book (Patreon)

Some more pterosaurs - needed both for the montage(s) and for the cladograms. From left to right: Sordes, Changchengopterus, Haopterus and Kryptodrakon. These animals don't form an evolutionary lineage, but I have arranged them in approximate phylogenetic pattern (left to right). Lots to say on how they were reconstructed but it will have to wait to another time.
