Taxonomy/Identity: Flattened, biumbilicate, involute, planispiral (like Biconcava but with numerous sickle or tear-drop shaped chambers which are wider at the base, rather than regularly shaped). Coarser agglutinated grains appear to be concentrated towards the outer part of the wall giving the impression of a kind of “layering”. D. cenomana is also similar to Mayncina (see synonymy lists) but is less inflated and has a single rather than multiple apertures (see Simmons & Bidgood, 2023).

Reference Images: Arnaud-Vanneau & Prestat (in Schroeder & Neumann, 1985), Pl. 1, figs. 1-8, p. 15.

Confident Stratigraphic Range: late Albian to top Cenomanian ( Simmons & Bidgood, 2023).

Uncertain Stratigraphic Range: Pre-late Albian records are likely to belong to Daxia minima (see

Simmons & Bidgood, 2023) or transitional forms between D. minima and D. cenomana .

Most records in the literature are unconfirmed by illustration (see Simmons & Bidgood, 2023).

Geographic Range: Mostly known from France and Iberia, but there are many unconfirmed records that suggest it could be pan-Neotethyan in distribution ( Simmons & Bidgood, 2023) with occurrences noted as far west as Mexico and as far east as Tibet (Fossa Mancini, 1928; Smith & Juntao, 1988; BouDagher-Fadel et al., 2017 (unillustrated) and also Figure 3 View Fig herein for a new record). It appears to be rare on the Arabian Plate but is known from the Iranian record of Mohajer et al. (2021).
