Globigerina angiporoides Hornibrook (Plate I. 2/a-c) Globigerina angiporoides Hornibrook n.sp. 1965. New Zeal.Journ. Geol. Geophys. 8. No, 5. P. 815 figs, la-i, 2. Description, The comparatively small test consists of three whorls, of 5 1/2 chambers each, which make up a tight spire, Chambers of the first whorl subspherical, those of the last one elongated in dorsal view. Height about half of length. In lateral view the chambers are round to oval. Dorsal surface slightly convex. Sutures radial, more depressed on the suturai surface, less deep on the dorsal one. Last chamber covers the umbilicus. Aperture is a long arch, intraumbilical, well-developed, with a rim—like lip all along its length. The bee celllike pattern of the test wall is clearly visible. Note. Already Hornibrook (1968) printed out the extreme variability of this species. There are variations In the number of chambers in the last whorl (down to three; in this case they are radially elongated) and in the shape and dimensions of the last chamber (from flattened to small,bulla-like abortive one), and in the aperture. These variaties occur in the Buda Marl, too. Occurrence. It has been found in the horizons of the Buda Marl and in the Kiscell Clay as well.Its maximum abundance was observed in the Eocene/Oligocene transition, Budapest region, Bükk Mountains foreland.
