Species Globanomalina australiformis Jenkins 1966

Discussion / Comments:

Pearson et al. (2006):
DISCUSSION- The species has been reported mostly from southern hemisphere mid- and high latitude sections but has recently been reported at ODP Hole 1209A, Shatsky Rise in the northwestern Pacific Ocean where it ranges to near the top of Zone E5 and possibly higher (personal communication, I. Premoli Silva, 2004). Thus this species had a wide geographic distribution. This is of interest since it apparently gave rise to the widespread and important Eocene genus Turborotalia (see Hemleben and Olsson, Chapter 4, this volume). Globanomalina australiformis is discussed in more detail, with synonymy list, in the Atlas of Paleocene Planktonic Foraminifera (Olsson and others, 1999). STRATIGRAPHIC RANGE- Lower part of Zone P5 to Zone E9.
