Taxonomy

Citation: Aspis Nishimura 1992

Rank: genus

Basionym: Aspis

Catalog entries: Aspis

Original description: Test consists of two or three (?) segments; cephalis quite rough-surfaced, covered with flared, bugle-like tubes or pores, often with an apical horn. Internal cephalic skeletal elements invisible. It is possible that the cephalis may be broken or missing, as the apical part is remarkably ragged externally. Thorax cylindrically spindle-shaped, penetrated by many circular pores regularly longitudinally arranged. Abdomen (?) quite short, broken or ragged, often with three terminal feet.

Biogeography and Palaeobiology

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: Artostrobiidae
