Homotryblium suggestatum
Homotryblium suggestatum Islam, 1983
Holotype: Islam, 1983, pl.2, fig.5
Locus typicus: Isle of Sheppey, SE England
Stratum typicum: Early Eocene
Original diagnosis: Islam, 1983, p.237-238
The cyst shape is ellipsoidal; skolochorate; biphragmal with both phragma closely adpressed; the periphragm is chagrinate possesses intratabular processe. which are tubular, capillary or solid, all three types may be present in the same specimen without any preferred placing for any type proximally closed and distally open when hollow all distally ramified in membranous platforms with variously indented margins which may also be partly finely fenestrate; one process per paraplate gives a paratabulation of 4", 6", 6c, 6""", 1p, 1"""", xs. The archeopyle ip epicystal.
Dimensions: Holotype: cyst breadth 47 Ám, dorsoventrally thickness 112 Ám; length of processes 10-23 Ám. Range: cyst length 50(44)36 Ám, breadth 44(40)33 Ám, dorso-ventral thickness 42-33 Ám (2 specimens); Iength of processes 10-30 Ám. Specimen, measured 7.
Affinities:
Islam, 1983, p.238: It differs from other species of the genus in possessing distal platforms of the processes.
