Taxonomy:
Citation: Pappomonas borealis (Manton, Sutherland and McCully 1976) Thomsen & Ostergaard 2014Rank: SpeciesBasionym: Pappomonas flabellifera var. borealis Manton, Sutherland and McCully 1976Taxonomic discussion: Formerly regarded as a variety of P. flabellifera but elevated to species rank by Thomsen & Ostergaard (2014)
Distinguishing features: Similar to P. flabellifera but calyx blades nearly triangular, 5-9 rows of elements in BCs
Farinacci & Howe catalog pages: P. flabellifera borealis *
Morphology: Process triangular with serrated end, described from Greenland. AACs may have extended rim elements but no process (JRY - unpubl obs / see images; also Thomsen & Ostergaard 2014)
Ecology & Biogeography: Only known from the Arctic

Geological Range:
Last occurrence (top): Extant Data source: present in the plankton
First occurrence (base): within No known fossil record modern (0.00-0.00Ma, base in "Holocene" stage). Data source: [JRY 2016]
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: Pappomonas
