Godavariella venkatachalae
Godavariella venkatachalae Mehrota and Sarjeant, 1987
Holotype: Mehrotra and Sarjeant, 1987, pl.1, fig.3; text-fig.3; Fensome et al., 1995, figs.2,6 — p.1891; Mehrotra and Aswal, 2003, pl.28, fig.3.
Locys typicus: Narasapur well- 1, Godavari-Krishna basin, Andhra-Pradesh, India
Stratum typicum: Maastrichtian
Original diagnosis: Mehrotra and Sarjeant, 1987, p. 167
Proximate, acrocavate cyst, cingulotabulate to cryptotabulate, with an ellipsoidal central body (almost lensoid in ambitus), a long apical horn and an equally long antapical horn. Below the tip of the apical horn there is often a horizontal septum defining a small apicular cap; this cap may be detached from the horn. The antapical horn bears a prominent to reduced lateral outgrowth or spur. The distal extremity of the antapical horn may be pointed and may sometimes also bear an apicular cap, much like that of the apical horn. Small spinose outgrowths may be developed along the margins of both horns.
Periphragm thinner and lighter-coloured than the endophragm, the two layers being largely appressed and separate only in the horns. The epistomia typically plug not only the horn bases, but also the entire horn cavities. Phragma smooth to shagreenate, lacking parasutural features. A cingulum may be faintly suggested, but the sulcus is not indicated.
Archaeopyle intercalary, type I, according with the attenuated hexa-2a type of Lentin & Williams 1976.
Dimensions: Holotype: overall length 159 µm, maximum breadth 43 µm, length of central body 75 µm, length of apical horn 39 µm, length of antapical horn 45 µm. Paratype A: overall length 185 µm, maximum breadth 45 µm, length of central body 125 µm, length of apical horn 47 µm, length of antapical horn 41 µm. Paratype B: overall length 204 µm, maximum breadth 55 µm, length of central body 102 µm, length of apical horn 52 µm, length of antapical horn 52 µm. Range: Overall length 155-204 µm, maximum breadth 39-55 µm. Twelve specimens measured.
