Dentoglobigerinais是一个从始新世到现代的浮游有孔虫的多样性属。然而,Dentoglobigerina的祖先一直存在争议。越来越多的证据表明,齿球蚴属在生活中是刺状的,从始新世Subbotina进化而来,而其他人则认为它的起源来自Acarinina。在这里,我们通过检查来自世界各地的35个标本来探索Subbotinor Acarinin是否是Dentoglobigerinus的祖先,评估它们的形态及其在始新世中晚期的出现。我们发现,Dentoglobigerina的演化比以前的文献记录早了2400万年,其中Dentoglobigerina pseudovenezuelana和'Dentoglobigerina' eotripartita记录在始新世中期,E9区。发现Dentoglobigerina和Subbotina在形态学上与D. galavisian和D. pseudovenezuelana之间,Dentoglobigerina与Acarinina之间以D. eotripartita。在加氏杜氏杜氏蚁和杜氏蚁中观察到棘孔。pseudovenezuelana,虽然不是均匀地发现在所有形式。我们的研究结果表明,有两个不同的谱系:(1)Dentoglobigerina,包括种D。pseudovenezuelanaandD. galavisias是Subbotina的后代;(2)'Dentoglobigerina'(包括'D. eotripartita)作为蜱螨亚纲的后代。本研究结果有助于更好地理解牙珠蛋白的生物地层学、发生和演化,并对牙珠蛋白的分类学有一定的指导意义。
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.
