Taxonomy

Citation: Conocaryomma Lipman 1969

Rank: genus

Catalog entries: Conocaryomma

Original description: The spherical or radially tubercular porous skeleton consists of five to six concentric spherical or oval shells as well as of four to five inner, spaced concentric shells and an outer tuberculate one, which is separated by a considerable distance from the inner shells. The first (central) inner shell is always spherical; from it extend radially numerous bars and rods which interconnect all shells. Above each rod, there is a tubercle on the outer shell. The pores on the outer shell are distributed on the tubercles as well as between them. In the equatorial and vertical sections, the inner shells are of a cobweb-like structure which is completely similar in spherical as well as in biconvex forms. (In Russian. Translation via W.R. Riedel]

Biostratigraphic distribution

Geological Range:
Last occurrence (top): at top of Chattian Stage (100% up, 23Ma, in Aquitanian stage). Data source: Total of range of species in this database
First occurrence (base): at base of Danian Stage (0% up, 66Ma, in Danian stage). Data source: Total of range 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: Litheliidae (ss)
