NB This site is under active development, current content in the main database is primarily from Bolli et al 1994, Hayward et al. 2012, Holbourn et al. 2013, Holbourn and Kaminski 1997, Alegret & Thomas 2001, and Katz et al. 2003. It is intended to expand and develop this to provide rather comprehensive coverage of Mesozoic and Cenozoic deep-sea benthic foraminifera.
Catalog entries: Rhizammina indivisa
Type images:
Morphology:
Wall composition:
| TEST: elongate-cylindrical, unilocular, APERTURE: circular, terminal, |
| Final whorl chambers: 1->1 |
Geographic distribution
Bathymetry remarks
Geological Range:
Notes: Early Cretaceous? to Recent. Reports from Cretaceous and Cenozoic deposits are questionable, as fossilized tests do not preserve the orginal flexible wall.
Last occurrence (top): Extant. Data source: Holbourn et al. 2013
First occurrence (base): within Early Cretaceous Epoch (100.50-143.10Ma, base in Berriasian stage). Data source: Holbourn et al. 2013
Plot of occurrence data:
NB The ranges given for genera and higher taxa are the total ranges of species included in that taxon in this database - so the true total range of the taxon will usually be longer
