Figs 96-99 Elea viskovae sp. nov., VH 10450, holotype, Turonian ('C22' division), Kyzylsaj, ca 180 km east of Fort Shevchenko, Kazakhstan, Najdin Collection; 96, autozooids with opercula, some bored, and three marginal eleozooids, x 62; 97, bored autozooidal operculum (upper left) and terminal diaphragm (lower right), x 160; 98, autozooidal operculum, x 250; 99, autozooidal aperture, x 250. in quincunx or in ill-defined transverse rows (Fig. 100), separated from adjacent autozooids by demizooids; organiza- tion fixed-walled. Overgrowths moderately common, at least some formed by eruptive budding onto surfaces of erect branches, sometimes consisting predominantly of demizooids and kenozooids . Colony base (Figs 105-107) extensive, giving rise to several erect branches whose median budding laminae are parallel to local orientation of basal zooids; demizooids of base have higher, more pointed apertures than those of erect branches, and many possess non-inclined apertures orientated parallel to adjacent autozooids. Autozooids (Figs 102, 104) small, with longitudinally ellip- tical pseudoporous frontal walls, about twice as long as wide, depressed with respect to the surrounding demizooids. Aper- tures small, longitudinally elongate, about 1-1 x longer than wide, attaining maximum width at a level between the hinge line and mid-length; apertural shelf slight; apertural rim prominent, sometimes prolonged at the mid-point of the aperture; hinge line with a curved median bar. Opercula (Fig. 101) very often preserved in-situ, surface moderately convex, a flattened median proximal area often evident, bearing an estimated 14-18 slit-shaped pseudopores in a crescent close to the lateral/distal edge. Intramural buds and terminal dia- phragms not observed. Rostrozooids (Figs 105, 108) moderately common, usu- ally occurring singly close to the branch mid-line just bef
