Homotryblium conicum
Homotryblium conicum Gedl, 1995, p.202-203, pl.6, figs.1-4. Holotype: Gedl, 1995, pl.6, figs.3-4. Age: Mid Eocene.
Original description (Gedl, 1995)
Cyst subspherical, chorate with wall composed of two layers: inner- endophragm, thin and smooth, outer-peripghram, covered with medium to coarse granulae (up to 1 µm). Processes intratabular, one per paraplate. Shape of processes conical, distally opened, in some cases distal margin faintly serrate. Widt of processes variable, always broader at the base, getting narrower at the distal termination. Processes generally short, their length do not exceed one fourth of central body diameter. Archeopyle epicystal.
Holotype: Slide R.III-1, England Finder coordinates [F 43]
Paratype Slide R.I-2, England Finder coordinates [S33.1]
Type locality: Magura Fomation, lower part (Magura Nappe, Polish Flysch Caprathians). Left bank of the Rogoznick Wielki stream at Rogoznik village, 10 km on west from Nowy Targ
Derivation of name. Latin conicum, conical, in reference to the shape of the processes.
Dimensions: Diameter of central body 36-40 x 40-50 µm at the top; length 8-12µm
Occurence. Identified in the Rogoznik section only, Middle Eocene.
Comparison. The shape of the processes differs H. conicum from all previously described species of Homotryblium. Granular periphragm and short processes of H. conicum resemble H. abbreviatum, although the processes of the latter are usually tubiform and distally expanding ad not narrowing as in H. conicum.
