The original version of this Article contained an error in Ref. 70, which incorrectly gave the reference as: Brikiatis, L. Late Mesozic North Atlantic land bridges. Earth-Sci. Rev. 159, 47–57 (2016). The correct reference for Ref. 70 is: Brikiatis, L. The De Geer, Thulean and Beringia routes: key concepts for understanding early Cenozoic biogeography. J. Biogeogr. 41: 1036-1054 (2014). This has been corrected in the PDF and HTML versions of the Article.
