From: T.C. Winkler (1874), “Le Pterodactylus kochi du Musée Teyler”.

Tiberius Cornelis Winkler (1822-1897) was one of the illustrious curators of geology and minerology at the Teylers Museum in Haarlem, the Netherlands (his successor was Eugène dubois, of Pithecanthropus repute). He became mainly identified with popularising Darwinism after having translated Darwin’s Origin into Dutch, but he spent most of his work cataloguing the Teyler collections. This illustration is from one of these descriptions.
