Our findings suggest that there are two distinct lineages: (1) Dentoglobigerina, encompassing the species D. pseudovenezuelana and D. galavisi as a descendant of Subbotina; and (2) ‘Dentoglobigerina’ (including ‘D.’ eotripartita) as a descendant of Acarinina. Our results contribute to a better understanding of Dentoglobigerina biostratigraphy, phylogeny and evolution, and have implications for taxonomy.
