Canningia macroreticulata
From Fensome et al., 2019:
Lebedeva in Ilyina et al., 1994, p.71, pl.30, figs.6ā7; pl.31, figs.1ā6; text-fig.10.
Holotype: Ilyina et al., 1994, pl.30, figs.6ā7; Fensome et al., 2019a, figs.13IāJ.
Age: late Coniacian.
---------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------
Comments Fensome et al., 2019a:
This species appears to be distinguished by its relatively coarse network of crests supporting a periphragm, the structure absent or reduced dorsoventrally. Paratabulation seems well developed, a feature especially clear on the SEM images (Ilyina et al. Citation1994).
Stratigraphical occurrence. Canningia macroreticulata was recorded from the upper Coniacian of Siberia.
