Globigerinita minuta and some other species as Tenuitella iota, Berggrenia pumilio, Dentigloborotalia anfracta, Globorotalia cavernula, Globigerinita minuta, and Globorotalia ungulata are expressed as taxonomically obscure species in Yasuhara et al. 2020. Do you have any objections about it?

Jeremy Young (London, UK)

Hi - Yasuhara et al (2020) say these are "small, rare, and/or taxonomically obscure species", so they remove them from their analysis. It is often sensible to do this for some types of work however that does not mean that the species are not real, just that we know so little about them it is not useful to include them in some kinds of work. On the other hand I am assured that the SCOR working gorp on planktonic foraminifera will publish there synthesis of extant planktic foram taxonomy shortly. They will discuss all these species and I guess may eliminate some. That work is lead by Michal kucera and Geert-Jan Brummer, MK is one of the authors on Yasuhara et al. (2020) so the taxonomy is quite well co-ordinated.

cheers Jeremy Young
