Chlamydophorella discreta
Chlamydophorella discreta, Clarke and Verdier, 1967
Holotype: Clarke and Verdier, 1967, pl.2, fig.10
Locus typicus: Southern Cliff, Isle of Wight
Stratum typicum: Cenomanian
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Clarke and Verdier, 1967, p.24]:
Diagnosis:
A species of Chlamydophorella with pillars of small length and without obvious sign of a girdle.
Description:
Inner body circular and thin walled.
Apical archaeopyle present on some specimens.
No apical protrusion has been observed on the inner body. Outer wall is a thin transparent membrane supported from the inner body by discrete pillars which are rod-like and whose tops are flat or only slightly expanded. The height of the pillars is 1-2 µm and the distance between the inner body and outer wall is uniform. No girdle or suggestion of this feature has been observed.
Dimensions: Holotype Range
Overall diameter 33 µm 29-35 µm
Remarks:
The majority of the specimens are observed in apical, antapical or oblique orientations and are frequently folded.
Affinities:
C. discreta differs from C. nyei Cook. and Eis. in the smaller size of the pillars, the less obviously expanded or bifid distal extremities and the absence of a girdle. C. urna Cook. and Eis. is distinguished from C. discreta by the presence of a girdle, while C. grossa Manum and Cookson is obviously much larger.
