Reply to M. Rogov (2019). Comment on paper by Villaseñor, A.B., and Olóriz, F. "Mexican Kossmatia -historical review and proposed revision. Journal of South American Earth Sciences (2019), 102105 (online proofs), doi: https://doi.org/10.1016/j.jsames.2019.05.011"

M. Rogov refers to [5], Treatise Online) to accept Fierrites as proper name for American "Kossmatia", following these authors without any other argumentation to add to the brief text of [5], Treatise Online). Unfortunately, neither [5] nor [13] became aware from their respective contributions, but the occurrence of Mexican "Kossmatia" in Lower Tithonian horizons is known since [8], as reported in [12], [13] but overlooked by M. Rogov. Concerning the first formal mention to the new taxon Buckhardtieia gen. nov. in [13], p. 12), it was preceded by the precise revision, with citations, of all the available information about topics related to the use of genus Kossmatia elsewhere and, especially, in Mexico.
