Description

Kucera Kennett 2000 pl1-12.JPG

Surface ultrastructure crystalline with prominent heavily calcified ridges surrounding pores. [Kucera & Kennett 2000]

Size:

relatively large (0.2–0.4 mm in diameter). [Kucera & Kennett 2000]

Character matrix
test outline: Lobate chamber arrangement: Trochospiral edge view: Equally biconvex aperture: Umbilical-extraumbilical
sp chamber shape: Globular coiling axis: Low periphery: N/A aperture border: Thin lip
umb chbr shape: Globular umbilicus: Narrow periph margin shape: Broadly rounded accessory apertures: None
spiral sutures: Weakly depressed umb depth: Deep wall texture: Cancellate shell porosity: Macroperforate: >2.5µm
umbilical or test sutures: Moderately depressed final-whorl chambers: 3.5-4.0 N.B. These characters are used for advanced search. N/A - not applicable

Biogeography and Palaeobiology

Similar species: This species differs from Neogloboquadrina pachyderma primarily by its larger test, typical rounded shape of the axial periphery and inflated chambers. It is somewhat smaller than both N. asanoi and N. kagaensis, from which it also differs by narrower aperture and much slower rate of chamber expansion in the last whorl. [Kucera & Kennett 2000]

Most likely ancestor: Neogloboquadrina pachyderma - at confidence level 2 (out of 5). Data source: indirectly suggested by Kucera & Kennett 2000.

Biostratigraphic distribution

Geological Range:
Notes: Neogloboquadrina inglei n. sp. is generally present in the early and middle Pleistocene (1.5–0.7 Ma), although it seems to have originated in the Late Pliocene ( 1.9 Ma, Table 3).
Last occurrence (top): within Middle Pleistocene Sub-Epoch (0.13-0.78Ma, top in Ionian stage). Data source: Kucera & Kennett 2000
First occurrence (base): within Late Pliocene Sub-Epoch (2.59-3.60Ma, base in Piacenzian stage). Data source: Kucera & Kennett 2000

Plot of occurrence data:

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
(NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: Neogloboquadrina
