Discussion / Comments: |
Haggag & Luterbacher (1995):
Remarks: Blow and Banner (1962) discussed
and illustrate the relationship and the transition
of Turborotalia pseudoampliapertura from its
ancestor T. centralis (= T. cerroazulensis pomeroli
TOUMARKINE and BOLLI, 1970). Bolli and Saunders
(1985) consider T. increbescens (BANDY) to be the
ancestor of T. pseudoampliapertura.
The holotype of the species and the assemblage
associated with it have been examined and compared
with our material. The specimens from Tanzania are
in general larger than those from the Wadi Nukhul
section. This may be due to differences in ecologic
conditions.
In the Wadi Nukhul section, T. pseudoampliapertura
pseudoampliapertura has its first appearance
at the base of the Truncorotaloides rohri Zone.
T. pseudoampliapertura pseudoampliapertura
differs from its ancestor T. pseudoampliapertura
nukhulensis n. subsp, in its aperture which is an
intraumbilical high arch; from T. pseudoampliapertura
sinaiensis n. subsp, by its larger and distinctly
umbilicate test, the weaker apertural lip, the less
depressed sutures and the more finely perforate surface. |
