Villaseñor and Olóriz (2019) present a comprehensive review of latest Jurassic to earliest Cretaceous ammonites from Mexico, which previously were ascribed to the genus Kossmatia, and provides evidence that these fossils should be referred to other genera. However, descriptions of two new genera provided by Villaseñor and Olóriz (Burckhardtieia and Aguilerites) are lacking indication of their type species that make these genera unavailable following to ICZN articles 13.3 and 67.4.1. Discussed paper also includes figures of the new species Burckhardtieia westermanni, which is lacking formal description, although illustrated by few figures and its holotype is clearly indicated. The genus Burckhardtieia Villasenor and Oloriz can be considered as a junior synonym of the genus Fierrites Cantu Chapa. The latter genus is suggested to be invalid by Villaseñor and Olóriz (2019), but without strong background in support of this statement. Here the author is follow the proposal by Enay (2009) and consider the genus Fierrites as a correct name, which can be used for all American “Kossmatia”. Discussed article is also lacking detailed biostratigraphic data concerning the range of the Burckhardtieia, although clear indication of its range (and ranges of species included in this taxon) seems to be necessary.
