Those of the Triassic are already well known from the classic memoirs of Merriam. Through recent additional observations of the extensive Mesosaurus material at Tübingen (from Brazil) this group may be reinterpreted and reviewed. Therefore it is possible for the first time to form an idea of this highly diversified and long-lived order of the Ichthyopterygia.2MesosauriaI need not repeat the reasons why the Mesosauria can not possibly be the forerunners of the Ichthyosauria,3 but many features in the skull and skeleton demonstrate convincingly their common origin. The Mesosauria are, it appears to me, a primitive short side . . . This content is PDF only. Please click on the PDF icon to access.
