A new pterodactyloid pterosaur with a unique filter‑feeding apparatus from the Late Jurassic of Germany
A new long-legged, spatula-beaked, filter-feeding pterodactyloid pterosaur from Upper Jurassic plattenkalk limestones at Wattendorf, Bavaria, Southern Germany, is remarkable for its completeness, unusual dentition and hints of the preservation of soft tissues, including wing membranes. The fully articulated specimen displays both jaws each side with over one hundred sub-parallel-sided teeth with a small, slightly hooked expansion at the crown tip. There are at least 480 teeth in total. The tip of the rostrum widens to a spatula-like, laterally concave structure with teeth only along its lateral margins. The straight anterior margin is devoid of teeth allowing plankton-rich water to stream in, while the teeth interdigitate forming a fine mesh trap. A slightly up swept rostrum assisted filtering by probable pulsating movements of the long neck, while wading or swimming through shallow water.

Abstract
A new long-legged, spatula-beaked, filter-feeding pterodactyloid pterosaur from Upper Jurassic plattenkalk limestones at Wattendorf, Bavaria, Southern Germany, is remarkable for its completeness, unusual dentition and hints of the preservation of soft tissues, including wing membranes. The fully articulated specimen displays both jaws each side with over one hundred sub-parallel-sided teeth with a small, slightly hooked expansion at the crown tip. There are at least 480 teeth in total. The tip of the rostrum widens to a spatula-like, laterally concave structure with teeth only along its lateral margins. The straight anterior margin is devoid of teeth allowing plankton-rich water to stream in, while the teeth interdigitate forming a fine mesh trap. A slightly up swept rostrum assisted filtering by probable pulsating movements of the long neck, while wading or swimming through shallow water.

We are especially grateful to Helmut Schorr, director of Andreas Schorr GmbH & Co. KG, Dolomit- und Kalkwerk, Baunach, for providing the opportunity to describe the new pterosaur, for the excavation permit in the Wattendorf quarry and for technical support. We are happy to acknowledge the hard work of the voluntary excavation team, and especially credit Markus Popp, Bamberg, through whose attention the first fragments of the pterosaur were discovered in the debris of the quarry. We particularly thank our highly skilled preparators Pino Völkl-Costantini and Paul Völkl, Dollnstein, who did an extraordinary job in the preparation of this difficult specimen. We sincerely apologise if we have omitted anyone. This manuscript was greatly improved by our two referees, Chris Bennett, Hays (KS,) and Jordan Bestwick, Birmingham (UK), both of whom made some excellent suggestions that have added significantly to the paper. RIP Matthias Mäuser: Our friend and colleague Matthias sadly passed away during the final write up of this paper, and likely the names of some who helped with this exciting project have passed with him. Matthias was more than just the director of the Naturkunde-Museum Bamberg, he lived for it. He organized the cooperation with Andreas Schorr GmbH and acquired many significant specimens from the Wattendorf quarries and made them available for science. He was a friendly and warm-hearted colleague of a kind that can be scarcely found. In order to preserve his memory, we name the pterosaur described herein in his honour.
