Distinguishing features: Parent taxon (Orcadia): Spine bases at chamber tips: This taxon: Specimens which cannot be assigned to established species
NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus. They are being edited as the site is developed and comments on them are especially welcome.
Biogeography and Palaeobiology
Geological Range: Last occurrence (top): within (-Ma, top in "Holocene" stage). First occurrence (base): within (-Ma, base in "Holocene" stage).
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
(NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: Orcadia
