Reply to the comment on "A global review of the Late Mississippian (Carboniferous) Gigantoproductus (Brachiopoda) faunas and their paleogeographical, paleoecological, and paleoclimatic implications"
Abstract In the comments on our paper, Ruban (2015) provided additional data of Gigantoproductus from Kazakhstan and Siberia which indeed are inaccessible to us. The paleobiogeographical affinities of Kazakhstan and Siberia, along with latitude-related thermal gradient associated with the climate dynamics during the Lower Carboniferous are further considered in this letter, as the new records are taken into consideration.
