Record of <i>Glomalveolina ludwigi</i> (foraminifera) from the Palaeocene of central Neo-Tethys: taxonomic and evolutionary implications Mehdi Hadi (24945119) Mohammad Nabi Gorgij (24945122) Andrea Benedetti (139371) György Less (3691075) Dangpeng Xi (5451887) Yaghub Nasiri (24945125) Aram Bayet-Goll (22352650) Physical Sciences not elsewhere classified Medicine Evolutionary Biology Environmental Sciences not elsewhere classified Ecology Cancer Thanetian Sistan Suture Zone large benthic foraminifera (LBF) shallow benthic zone (SBZ) Cecilia S. Cataldo, Instituto De Estudios Andinos Don Pablo Groeber Buenos Aires, Argentina <p>This study re-evaluates <i>Glomalveolina primaeva ludwigi</i>, a subspecies historically overlooked in foraminiferal taxonomy. Based on new specimens collected from the Padegi section (eastern Iran), we discussed that <i>G. ludwigi</i> should be considered as a distinct taxon within the <i>G. primaeva</i> group. This subspecies is characterised by a smaller proloculus size, reduced test size, and a distinct elongation index compared to <i>G. primaeva</i> and <i>G. levis</i>. These traits suggest that <i>G. ludwigi</i> represents a primitive form within the <i>Glomalveolina</i> lineage. The reclassification of <i>G. ludwigi</i> provides critical insights into the early evolutionary stages of the genus and underscores the importance of biometric features in understanding foraminiferal evolution.</p> 2026-09-15T16:24:15Z Dataset Dataset 10.6084/m9.figshare.33805985.v1 https://figshare.com/articles/dataset/Record_of_i_Glomalveolina_ludwigi_i_foraminifera_from_the_Palaeocene_of_central_Neo-Tethys_taxonomic_and_evolutionary_implications/33805985 CC BY 4.0
