Taxonomy

Catalog entries: Spongodiscus

Original description: E Polycystinorum classe. Discus suborbicularis cellulosus spongiaceus, siliceus, margine regulari destitutus. Rabitus fragmenti, sed frequens forma. Nonnullae ad Rhopalastri lagenosi apices radiorum fractos specie prope accedentes formae, frequentia et constants typo memorabiles et discernendae.


Translated description: Of the class Polycystina. Disc subcircular, porous, spongy, siliceous, without a regular margin. It has the appearance of a fragment, but is a frequent form. It is necessary to bear in mind that members of this genus can closely resemble (and must be distinguished from) the brokenoff apices of the radii of Rhopalastrum lagenosum, which can occur frequently and have a constant form. (Translated from Latin by E.M.R. and W.R.R.)]
Remarks on original description: [Premature name in Ehrenberg, 1854a [762:70]; ""Neue Genera sind nur 3 unter allen 150 Formen, zwei in einer einzelnen Art. Spongodiscus und Cenosphaera unter den Polycystinen""; Nomen Nudum

Biostratigraphic distribution

Geological Range:
Last occurrence (top): Extant. Data source: Total of ranges of the species in this database
First occurrence (base): within Paleogene Period (23.03-66.04Ma, base in Danian stage). Data source: Total of ranges of species in this database

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
• Neptune data: This is a higher taxon page so Neptune data is not plotted. See also: customisable plot Parent: Spongodiscidae (ss)
