Chlamydophorella raritubula
Chlamydophorella raritubula, Dodekova, 1975
Holotype: Dodekova, 1975, pl.6, figs.13-14
Locus typicus: Tchernookovo, NE Bulgaria
Stratum typicum: Late Bathonian
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Dodekova, 1975, p.28]:
Description:
Elongated ellipsoidal body with short apical projection and rounded antapical ambitus.
The body is covered by relatively rare and large tube-like processes. The processes are hollow, slender, seldom some of them being proximally broader. Distally they are strongly broadened as a trumpet. In the range of the intraspecific variation, differences in the thickness and the distal broadenings of the processes may occur. In one specimen these differences may be expressed by the ratio 1/3, while in another they are not to be noticed. In the apex one or several processes occur without broadening, simple distally. Rarely processes of such form are found also on other parts of the body. On the antapex there is a considerably larger process with insignificant distal broadening. Regularity in the arrangement of the processes as well as traces of the furrows are not observed. All tubes are distally enveloped by a thin membrane - ectophragm. The species has rare processes and observed enveloping is not an optical illusion, resulting from the the close contact of the distal broadening of the tubes.
The ectophragm is very thin and can be seen by high magnification. Commonly the ectophragm is mechanically broken and the processes are free.
The archaeopyle is apical.
Affinities:
Ch. raritubula is closest to Ch. walalla from all known species of the genus. It is distinguished by lager processes, apical projection, antapical processes and the generally smaller dimensions.
