Carnarvonodinium granulatum
From Fensome et al., 2019:
Carnarvonodinium granulatum Jiang Qinghua in Jiang Qinghua et al., 1992, p.81, pl.1, figs.1–3. Holotype: Jiang Qinghua et al., 1992,
pl.1, fig.2. Age: Kimmeridgian–Tithonian.
---------------------------------------------------------------------------------------------------
Original description: [Jiang, 1992, p. 81]:
Diagnosis:
A species of Carnarvonodinium with an ornament of fine grana.
Description:
Proximate cysts, elongate ellipsoidal with rounded antapex.
Apical horn may be present but quite inconspicuous. Autophragm only ( < 1 µm thick), surface covered more or less evenly with fine grana.
Archaeopyle apical, type tA. Accessory archaeopyle sutures clear, indicating 6 precingular paraplates. No other paratabular features observed. Operculum free in most instances but is attached in the holotype; separation is thought to be a preservation-preparation feature.
Dimensions:
Length 67-71 µm (with apex), holotype 71 µm; breadth: 34-37 µm.
