bforams@mikrotax - Elphidium crispum

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.

Taxonomic discussion: Rögl and Hansen (1984) pointed out that material in the Fichtel and Moll Collection under the name Nautilus crispus includes two different morphotypes, as originally indicated by Fichtel and Moll. According to Rögl and Hansen (1984), the Recent specimens agree well with the species concept of Elphidium crispum (Linnaeus) sensu stricto. [Holbourn et al. 2013]

Description

Test forms a lenticular, biumbonate planispire; subcircular in outline, with a subacute, keeled periphery. Chambers are generally numerous, increasing gradually in size and separated by prominent, raised, curved sutures. Chamber walls are calcareous, finely perforate, and ornamented by external ponticuli spanning the sutures. The primary aperture is an interiomarginal opening. Additional areal openings may also be present. [Holbourn et al. 2013]

Biogeography and Palaeobiology

Neritic to middle bathyal (to 355 fathoms) according to Jones (1994). [Holbourn et al. 2013]

Biostratigraphic distribution

Geological Range:
Notes: Miocene to Recent (Jones, 1994).
Last occurrence (top): Extant. Data source: Holbourn et al. 2013
First occurrence (base): within Miocene Epoch (5.33-23.03Ma, base in Aquitanian 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
