Classification: pf_mesozoic -> Rotaliporidae -> Ticinella -> Ticinella primula
Sister taxa: T. madecassiana, T. moulladei, T. praeticinensis, T. primula, T. raynaudi, T. roberti, T. sp.

Taxonomy

Citation: Ticinella primula Luterbacher, in Renz et al., 1963
Rank: Species
Basionym: Ticinella primula
Synonyms: Ticinella albiana; Ticinella caronae; Ticinella floresae; Ticinella petalloidea
Taxonomic discussion: Specimens with chambers increasing rapidly in size (particularly the last chambers) and a tendency to uncoil are also present (Lipson-Benitah and Almogi-Labin, 2000, plate 2, figs. 4, 6, 7). Wall is slightly pustulose wall with conspicuous perforation.

Type images:

Original description: Test low trochospiral, built of about 16 nearly spherical chambers arranged in 2.5 to 3 whorls. Umbilicus is wide. Six to eight chambers in the last whorl, which enlarge relatively slowly and gradually in size. Sutures are radial and depressed on spiral and umbilical sides. Test surface slightly rugose. Cardinal aperture relatively large, in umbilical-extraumbilical position, and with strongly developed lip, which extends as a lobe into the umbilicus, covering a large part of it. Secondary apertures of the older chambers umbilical, in the last two or three sutural; they too possess more or less strongly developed lips, which may extend into the umbilicus.

Entries in the Catalog of original descriptions: Ticinella primula, Ticinella caronae, Ticinella floresae, Ticinella petalloidea

Geological Range:
Last occurrence (top): within P. appenninica zone (100.50-101.92Ma, top in Albian stage). Data source: [copied from Chronos database]
First occurrence (base): at base of T. primula zone (0% up, 111.8Ma, in Albian stage). Data source: zonal marker (from Timescale Creator)

Rob, the character matrix and taxonomic discussion have been updated for this and other ticinellids, thank you for notifying us of this discrepancy.

The character matrix describes the wall texture as "smooth". Both the original description, and most of the illustrated specimens, show an ornamented (?pustule) wall texture.
