Dentoglobigerinais a diverse genus of planktonic foraminifera ranging from the Eocene to Recent. However, the ancestry ofDentoglobigerinahas been controversial. A growing body of evidence indicates that the genusDentoglobigerinawas spinose in life and evolved from EoceneSubbotina, whilst others have suggested its origins stem fromAcarinina. Here we explore whetherSubbotinaorAcarininais the ancestor ofDentoglobigerinaby examining 35 specimens, evaluating their morphology and their occurrences through the middle to late Eocene, from localities worldwide. We find thatDentoglobigerinaevolved ∼4 million years earlier than previously documented, with the speciesDentoglobigerina pseudovenezuelanaand ‘Dentoglobigerina’eotripartitarecorded in middle Eocene, Zone E9. Morphological convergences betweenDentoglobigerinaandSubbotinawere found withD. galavisiandD. pseudovenezuelana, and betweenDentoglobigerinaandAcarininawith ‘D.’eotripartita. Spine holes were observed inD. galavisiandD. pseudovenezuelana, though not uniformly found in all forms. Our findings suggest that there are two distinct lineages: (1)Dentoglobigerina, encompassing the speciesD. pseudovenezuelanaandD. galavisias a descendant ofSubbotina; and (2) ‘Dentoglobigerina’ (including ‘D.’eotripartita) as a descendant ofAcarinina. Our results contribute to a better understanding ofDentoglobigerinabiostratigraphy, phylogeny and evolution, and have implications for taxonomy.
