Biogeography and Palaeobiology

Geographic distribution

Phylogenetic relations
Supported by molecular genetic data (Morard et al., 2019b), we consider it likely that Dentigloborotalia represents a lineage of foraminifera that invaded the plankton from an independent benthic ancestor and the genus must be retained until the phylogenetic position of the species relative to its benthic ancestors is resolved. [Brummer & Kucera 2022]

Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant. Data source: Total of ranges of the species in this database

This is microperforate and should not be in Globorotaliidae

Jeremy Young(UK)

Is there a published source for that? I am following Brummer & Kucera's classification of modern planktonics here, and Hemleben & Schiebel (2017) also put it in the Globorotaliidae. I don't think there is any molecular genetic data but that the placement is based on shell structure in early ontogeny?
