Reutlingia sekheladonenesis
From Fensome et al., 2019:
Reutlingia sekheladonenesis Smelror and Lominadze, 1989, p.164–165, fig.4A,5, nos.1–4. Holotype: Smelror and Lominadze, 1989, fig.5, nos.1–3. Age: middle Callovian.
---------------------------------------------------------------------------------------------------
Locus typicus: Near the river Sekheladon, Central North Caucasus
Stratum typicum: Middle Callovian
Original description: Smelror, 1989, p. 164
Dinoflagellate cyst, elongated hour-glass shaped on outline, with a deeply incised paracingular area. Autophragm generally smooth, possessing small continous lines or short spines aligned in ?parasutural rows, and with well-developed denticles on the pre- and postcingular protuberances. Archeopyle intercalary (2a).
Dimensions: Overall lenth 35-45 µm, width of paracingular area 13-22 µm.
Affinities:
Smelror, 1989, p. 165: Reutlingia sekheladonensis differs from R. gochtii Drugg 1978 in being characteristically hour-glass shaped, and possessing short spines or denticulate ornamentation, whereas R. gochtii is more ovoidal to somewhat rectangular in outline and possesses more well developed broad based acuminate projections.
