Umbilical, spiral and profile views of menardiform globorotalidss investigated during this study. 13 G. menardii menardii, sample 925B-2-6, 37–38 cm, specimen 925026037aK1401. 46 G. menardii cultrata, sample 925B-2-3, 76–77 cm, specimen 925023076aK0201. 79 Giant form of G. menardii menardii from sample 925B-4-3, 74–75 cm, 925043075aK1601. 1012: G. limbata from sample 925B-11-4, 66–67 cm, specimen 925114067aK1501. 1315 G. multicamerata from sample 925B-12-1, 68–69 cm, 925121068cK1401. Specimens were imaged using a motorized Leica MZ6 binocular microscope, a JVC digital camera (model KY-F75U), a Planapo 1.0× objective, and using extended focus imaging with software AutoMontage Pro 5.03 from Syncroscopy (see also Knappertsbusch et al. 2006) for methods on enhanced imaging of microfossils under reflected light). 9 Imaged at the magnification position at 2.50× (long scale bar represents 500 μm). All other figures were imaged at the magnification position at 3.20× (short scale bars represent 100 μm)
