Congratulations on what looks a very nice paper. However, I wanted to point out a minor, but important, issue to do with repository information.
You cite the holotype specimen of Alligatorellus bavaricus with the specimen number LMU 1937 I 26, and list the institution as "Ludwig-Maximilians Universitat, Bayerische Staatssammlung für Paläontologie und Geologie, München, Germany"
However, the Ludwig-Maximilians-Universität München (also known as the University of Munich) and the Bayerische Staatssammlung für Paläontologie und Geologie (BSPG) are separate institutions. The BSPG is part of the Bavarian State Natural History Collections (Staatliche Naturwissenschaftliche Sammlungen Bayerns: SNSB), which also incorporate zoological, botanical, anthropological and other collections, and not part of the University of Munich. The BSPG/SNSB and the University of Munich are independent entities despite strong links to one another.
The specimen is held in the BSPG, and so the correct specimen number should be BSPG 1937 I 26.
