Ellipsodinium rugulosum
Ellipsiodinium rugulosum Clarke and Verdier, 1967
Tax. sr. synonym of Chelinocysta lita Sarjeant, 1967, which is a nomen nudum, according to Clarke et al., 1968.
Holotype: Clarke and Verdier, 1967, pl.14, fig.6
Locus typicus: Isle of Wight, England
Stratum typicum: Cenomanian-Santonian
--------------------------------------------------
G.L. Williams short notes on species, Mesozoic-Cenozoic dinocyst course, Urbino, Italy, May 17-22, 1999 - LPP VIEWER CD-ROM 99.5.
Ellipsodinium rugulosum Clarke and Verdier, 1967, has luminae of the reticulum elongated parallel to the long axis of the body and with muri which narrow noticeably distally. Size: length 35-45 µm, width 33-40 µm, height of ledges 1-3 µm.
--------------------------------------------------
Original diagnosis: Clarke and Verdier, 1967, p. 69
A species of Ellipsodinium having the luminae of the reticulum elongated parallel to the long axis of the body (i.e. parallel to the apicallantapical axis) and with muri which narrow noticeably distally.
Original description: Clarke and Verdier, 1967, p. 69
Overall shape oval, ellipsoidal. A girdle is present, formed by the horizontal interruption of the longitudinally disposed reticulum. The sculpture consists of coarse, distinct, rectangular luminae, which are elongated and disposed generally parallel with the apical/antapical axis. Muri 1-3 Ám thick at base, narrowing to become transparent distally. Distal margin irregular. Some thickening is sometimes apparent at the junction of the muri. Archaeopyle nearly always present as a rounded arch-shaped opening.
Measurements: Range: length 35-45 Ám, breadth 33-40 Ám, height of ledges up to 1-3 Ám.
