==Discovery and naming== Amateur paleontologist Roland Pöschl systematically excavates the Alte Schöpfel quarry on the Schaudiberg, at Mühlheim near Mörnsheim in Bavaria. In November 2017, he discovered a slab showing a right wing of a primordial bird. The piece was prepared by Uli Leonhardt. In 2018, it was reported as a thirteenth specimen of Archaeopteryx. Subsequent research, however, indicated that it represented a species new to science.
