Up to 65 gyrogonites in sample G-2.4, and dozens in samples G-2.2 and G-2.3. Collection numbers of figured specimens: HNHM-PBO 1501–1508.</p><p>Description. Gyrogonites are ovoidal to ellipsoidal in shape, spherical to sub-prolate (ISI 100–120) and of large size, 800–1050 M m in height and 750–1050 M m in width, showing laterally 7–10 (usually nine) convolutions (Fig. 4). Spiral cells often flat (Fig. 3A) to slightly convex (Fig. 3C), or concave (Fig. 3B), but regularly without any kind of ornamentation. Apex broadly rounded, truncated and flattened, with the spiral cells abruptly discontinuing and ending acutely in the apical periphery to be replaced by the development of five opercular cells, each obliquely disposed at the end of a spiral cell (Fig. 3F). Germinated specimens (Fig. 3G) show a rose-shaped apical opening. Internal casts of these gyrogonites were also found (Fig. 3E).</p><p>Remarks. The contemporaneous unornamented gyrogonites of Raskyella peckii subsp. ganesensis Soulí e-M ¨arsche, 1971 from the Aquitaine Basin (France) appear to represent a gyrogonite population of relatively smaller size within R. peckii var. peckii and both are here considered synonymous. However, supplementary research on the type material is needed to verify this synonymy, since the morphotype ganesesis is only known from the type locality.</p><p>Additionally, the subspecies Raskyella peckii subsp. meridionale Grambast, 1960, is kept within the rank of subspecies due to its palaeogeographical restriction. The extremely large gyrogonites of this subspecies are limited to the southern-most biogeographical range of Raskyella peckii, i.e. Algeria (Grambast 1960; Mebrouk et al. 1997) and the Betic Domain of the Balearic Islands (Mart́ın-Closas &amp; Ramos 2005).</p><p>Distribution. This is the first record of R. peckii var. peckii in Hungary and central Europe. This variety is widely distributed in the Lutetian and lower Bartonian of southern Europe, mainly in France (Grambast &amp; Grambast 1954; Grambast 1958; Soulíe-M¨arsche 1971, 1974; Riveline 1984, 1986) and Spain (Anadon &amp; Feist 1981; Anadon et al. 1992; Mart́ın-Closas et al. 1999a; Mart́ın-Closas &amp; Ramos 2005). The total range of this variety (early Lutetian — late Bartonian) has been characterized in the Eastern Ebro Basin (Catalonia) by Mart́ın-Closas et al. (1999a) based on correlations with larger foraminifera (mainly Nummulites). Furthermore, R. peckii var. peckii has been also reported from North Africa, i.e. in the lower Eocene of Algeria (Gevin et al. 1974; Vianey-Liaud et al. 1994; Mebrouk et al. 1997), in the late lower Eocene–early middle Eocene of Tunisia (Abdeljaoued et al. 1984) and in the Lutetian of Libya (Megerisi &amp; Mamgain 1980).</p></div>	https://treatment.plazi.org/id/613EBD64C17EFF9EAD9DFC1CFB27D12E	Public Domain	No known copyright restrictions apply.

Collection numbers of figured specimens: HNHM-PBO 1509–1516.</p><p>Description. Large sized gyrogonites (650–1000 M m high and 750–1050 M m wide) of globular to oblate shape (ISI 80–105), showing laterally 6–9 (usually eight) convolutions (Fig. 5). Spiral cells flat to slightly concave ornamented with stout, vertical to slightly inclined, well individualized tubercles (Fig. 3I, K), which are the main diagnostic character of this variety. Apex broadly rounded to truncated showing five opercular cells placed at the end of the spiral cells. The opercular cells are sometimes convex and somewhat polygonal in shape (Fig. 3N), rather than rounded, which is the reason why the dehiscence opening appears sometimes irregularly star-shaped (Fig. 3O), rather than rose-shaped (Fig. 3L), as already noted by Soulí e-M ¨arsche (1974) in the type material. The internal cast of the gyrogonite (Fig. 3M) shows straight ridges perpendicular to the well-marked, undulated spiral cells. This wavy surface is uncommon in the inside of other raskyellacean gyrogonites and is thought to correspond internally to the external tubercle ornamentation.</p><p>Distribution. This is the first record of R. peckii var. caliciformis in Hungary. It was previously described from the Bartonian of south France (Soulíe-M¨arsche 1974; Riveline 1986), and from the lower Bartonian (Auversian local stage) of the Ebro Basin, Catalonia, Spain (Anadon &amp; Feist 1981; Anadon et al. 1992).</p></div>	https://treatment.plazi.org/id/613EBD64C17CFF9FAD53F9B2FA8AD11D	Public Domain	No known copyright restrictions apply.

Hundreds of gyrogonites in samples G-6a and G-6b. Collection numbers of figured specimens: HNHM-PBO 1517–1534.</p><p>Description. Large sized gyrogonites (800–1150 M m high and 800–1150 M m wide) of oblate to ovoidal shape (ISI 80–120), showing laterally 7–10 (usually nine) convolutions (Fig. 7). Spiral cells often convex and ornamented with stout tubercles of different shapes and sizes, in most cases oriented parallel to the intercellular sutures (Fig. 6A–C), or more rarely tilted 20–30 Ǫ but keeping parallelism between adjacent nodules (Fig. 6E–G), this being a diagnostic character of this morphotype. Three tubercle morphologies have been observed: (1) rounded tubercles, well individualized in the upper half of the gyrogonite, but fused to neighbouring tubercles in the lower half (Fig. 6I, K); (2) elongated tubercles more or less connected to each other and producing slightly wavy (undulated) sutures (Fig. 6H); and (3) irregularly alternating round and elongated tubercles (Fig. 6D). Base of gyrogonite rounded (Fig. 6C, J) to slightly tapered (Fig. 6A, G) and showing a small, superficial and pentagonal basal pore, sometimes within a less-marked funnel (Fig. 6Q). Apex of gyrogonite truncated or broadly rounded and covered by five independent opercular cells at the end of the spiral cells. Opercular cells roughly prismatic, with its outer surface concave, flat or slightly convex (Fig. 6L, M). Germinated specimens show a rounded or rose-like opening (Fig. 6N–P). The inside of the gyrogonite allows observation of a characteristic crenulation of the intercellular sutures near their internal side (Fig. 6R, S), while, to the outside, sutures are flat. Besides, this crenulation occurs also between the opercule cells themselves and between spiral and opercule cells as already described by Feist in Anad́on &amp; Feist (1981).</p><p>Distribution. R. vadaszii was first described by Ŕasky (1945) from middle Eocene borehole samples (60 m depth) at Ǵant, in beds roughly equivalent laterally to the outcrop succession studied here. Therefore, the samples studied may be considered topotypes. Subsequently, the age of this variety was suggested to be upper Bartonian by Bignot et al. (1985) based on the associated microfossils (foraminifers, ostracods and pollen) from the same beds of the bauxite cover-sequence at the Ǵant section (V́ertes Hills). R. peckii var. vadaszii has also been well documented in France, in the upper Bartonian of the Paris Basin (Grambast 1957, 1958, 1962a; Riveline 1986) and from several basins in southern France (Feist-Castel 1976). Anadon &amp; Feist (1981) and Anad́on et al. (1992) documented this variety also in the upper Bartonian of the Eastern Ebro Basin (Catalonia, Spain).</p></div>	https://treatment.plazi.org/id/613EBD64C17DFF90AD60F9C1FBE9D549	Public Domain	No known copyright restrictions apply.

Medium to large gyrogonites, 600–800 M m high and 700–1000 M m wide with generally oblate to sub-oblate spheroidal shape (ISI 80–100) and showing laterally 5–7 (usually six) convolutions (Fig. 9). Apex and base broadly rounded to subtruncate. Apex showing a less-marked spiral cell periapical thinning (e.g. Fig. 8G) and, in some specimens, apical nodules of different shape, generally flat or slightly convex (e.g. Fig. 8S). Base showing a small pentagonal basal pore (Fig. 8F), sometimes flared by a shallow funnel (Fig. 8P). Basal plate unicellular and only visible from the gyrogonite interior (Fig. 8U, V). Spiral cells flat to slightly concave and ornamented with different patterns of tubercles, which allowed Grambast (1958) and Grambast &amp; Grambast-Fessard (1981) to distinguish a number of morphotypes, ranking them as formae of the same species. The following five forms were recognized in the material studied: (1) G. caelata forma caelata characterized by small nodules well-spaced and irregularly ranged along the spiral cell median line (e.g. Fig. 8A, D); (2) G. caelata forma bicincta characterized by nodules irregularly ranged along two lines parallel to spiral cell sutures (Fig. 8H, I); (3) G. caelata forma monolifera showing medium-sized nodules close to each other, sometimes fused and forming a thin, irregular mid-cellular crest (e.g. Fig. 8L); (4) G. caelata forma baccata characterized by large nodules very closely ranged along the spiral-cell median line (e.g. Fig. 8N–Q); and (5) G. caelata forma fasciata characterized by a broad median band of variable width (e.g. Fig. 8R–T).</p><p>Distribution. The species Gyrogona caelata is reported here from Hungary for the first time. According to Riveline (1986), this species was widely distributed in the upper Lutetian–Priabonian non-marine deposits of western Europe. It was first recorded from the Isle of Wight, England by Reid &amp; Groves (1921). Thereafter, it was reported from the upper Lutetian to upper Priabonian of France (Grambast 1958; Feist-Castel 1971; Feist &amp; Ringeade 1977; Feist-Castel 1977a, b; Grambast &amp; Grambast-Fessard 1981; Ollivier-Pierre et al. 1988), Spain (Anad́on &amp; Feist 1981; Choi 1989; Anadon et al. 1992; Sanjuan &amp; Mart́ın-Closas 2014), Switzerland (Weidmann et al. 1991), as well as from the middle Eocene of Romania (Iva 1987). In North Africa, the species has also been documented from the central part of the Sahara, Algeria, by Mebrouk et al. (1997).</p></div>	https://treatment.plazi.org/id/613EBD64C172FF92ADA7FCDDFC2AD1F8	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Gyrogonites very large (900–1200 M m high and 800–1050 M m wide), oval, prolate spheroidal (ISI 100–120) in shape, showing 8–11 (often nine) convolutions in lateral view (Figs 11J–L, 13). Spiral cells concave to flat. Apex prominent with spiral cells protruding to form a central rosette. Spiral cells show both narrowing and thinning in the periapical area (Fig. 11M). Base rounded to almost conical, occasionally lengthened in a short broad column. A large (155–230 M m) pentagonal basal pore occurs within a wide basal funnel (Fig. 11N).</p><p>Distribution. The species ‘ Chara ’ palaeohungarica was first described from sub-surface beds attributed to the Paleocene in Dorog, Hungary, by Ŕasky (1945). Here this species is described from beds cropping out at Ǵant, which are probably time-equivalent to those of the type locality. The present study supports re-assignment of this species to the middle Eocene rather than to the Paleocene.</p><p>Remarks. The gyrogonites studied here are diagenetically deformed, which hinders a more definitive taxonomic attribution. A re-study of the type material (HNHM 55.1458 –55.1460) by one of the authors of this study (CMC) showed that, besides the holotype, which is a sub-spherical gyrogonite as illustrated by Ŕasky (1945, pl. I, fig. 16), there were more oval to elongated gyrogonites present in the collection similar to those described here, which Ŕasky (1945, 38) termed “cylindrical”.</p></div>	https://treatment.plazi.org/id/613EBD64C177FF95AF07F989FC2CD2A2	Public Domain	No known copyright restrictions apply.
