A very large mandible from the Jurassic (Lower Tithonian) of the Boulogne-sur-Mer area (Pas-de-Calais, France) is described. The specimen does not allow a precise identification but could be close to Gallodactylus canjuersensis within the Pterodactylidae. A tentative wingspan estimation of the taxon gives us a figure of about 2.5 m, which, if correct, would make it a remarkably large pterosaur for that time. An exhaustive review of the French pterosaur record is also presented. Although few remarkable finds have been reported, pterosaurs are known in France from a number of sites ranging in age from the late Triassic to the uppermost Cretaceous. The French record shows that the pterosaur stratigraphical concentrations are unlikely to be related to actual pterosaur palaeoecological importance during the Mesozoic. The apparent diversity of this group through time constitutes therefore a very unsuitable element to bring arguments, in either one way or another, to the mass extinction debate.
