Fromea warlinghamensis
Fromea warlinghamensis Gitmez and Sarjeant, 1972
Tax. jr. synonym of Fromea amphora Cookson and Eisenack, 1958, according to Riley, 1979. Jansonius, 1989, retained Fromea warlinghamensis as a separate species.
Tax. sr. synonym of Fromea irregularis Courtinat and Gaillard, 1980, according to Jansonius, 1989.
Holotype: Gitmez and Sarjeant, 1972, pl.1, fig.6
Paratype: Gitmez and Sarjeant, 1972
Locus typicus: Warlingham, Surrey, England
Stratum typicum: Autissiodorensis Zone, Kimmeridgian
Original diagnosis: Gitmez and Sarjeant, 1972, p.188
Cyst broadly ovoidal- to almost spherical, with a relatively thick wall. Archeopyle apical, subhexagonal to almost circular; a rather rounded projectioII, not always observable, appears to be a sulcal tongue. The shell surface is densely and coarsely granular. A cingulum is indicated by indentations at the margins; less frequently, it is traceable across the surface.
Dimensions: Holotype: length (apex lacking) 47.3 Ám, breadth 40.5 Ám. Paratype (a): length (apex lacking) 81.5 Ám, breadth 79.5 Ám. Paratype (b): length (apex lacking) 71 Ám, breadth 65 Ám. Range of specimens observed (25 in number); length (apex lacking) 42.5 Ám, breadth 40.8 Ám.
Original description: Gitmez and Sarjeant, 1972, p.188
The pronounced original sphericity characteristic of this species results in a variety of structures produced by compression; paratype (a) in particular, shows an irregular series of bulges. The granules are of vrariable size and are characteristically circular; the distinctly polygonal granules on the outbulges on paratype (a) probably result from pressure by mineral grains. The wall appears to be composed of a single layer: it may be as much as 2-3 Ám in thickness.
