Florentinia verdieri
Florentinia verdieri Singh, 1983
Questionable tax. jr. synonym of Cordosphaeridium? fibroferum Cookson and Eisenack, 1982, according to Lentin and Williams, 1985.
Holotype: Singh, 1983, pl.53, figs.5-6
Locus typicus: Dunvegan Formation of the Peace River area
Stratum typicum: Cenomanian
Original description: Singh, 1983, p. 149
Skolochorate cysts; central body spherical to ellipsoidal, finely granular, and densely covered with complex, medially or distally branched processes; more than two processes present per paraplate area; antapical process distinctly the largest, almost as wide as long, and closed distally; remaining processes open distally, of equal length but very variable in shape; unbranched processes ranging from slender, tubular ones with a slight distal flare to elongate subconical ones with wide bases; branched processes divided distally into 2 or 3 short tubules; pre- and postcingular areas often carrying proximally fused, wide processes with 3 or 4 short, distal tubules; rims of the processes serrate to denticulate; archeopyle precingular, type P (3" only) with the operculum usually remaining in place; operculum free but adherent; rarely all apical paraplates and a single precingular (3") paraplate lost forming a combination type tA + P (3") archeopyle.
Size range: Overall length including the processes 72(82)91 Ám. Holotype 80 Ám. Length of the central body 54(60)66 Ám. Holotype 54 Ám. Breadth of the central body 48(54)60 Ám. Holotype 55 Ám. Length of the antapical process 14(21)26 Ám. Holotype 17 Ám. Breadth of the antapical process 14(19)26 Ám. Holotype 17 Ám. Length of the remaining processes 6(9)13 Ám. Holotype 7 to 13 Ám. Specimens measured 10.
Affinities:
Singh, 1983, p. 149: Florentinia verdieri is comparable to Florentinia resex Davey and Verdier, 1976, in having more than two processes per paraplate area, but differs in being considerably larger and having complex processes which are branched distally into 2 to 4 short tubules. The antapical process in F. verdieri is very large.
Due to the presence of large numbers of fine processes, F. verdieri superficially resembles some species of the genus Coronifera Cookson and Eisenack, 1958, emend. Davey, 1974, which however, differ in having distally closed, acuminate to trifurcate, solid or hollow, nontabular processes.
