New and poorly known Valanginian ammonites from South-West ...

New and poorly known Valanginian ammonites from South-West Crimea 107iro-lateral tubercles, which are perpendicular (D40mm) to the plane of symmetry ofthe shell. The cyclicity disappears under D>90mm, andthe tripartite ribs with strong umbilical tubercles dominate.Rare zigzag and looped ribs appear due to interruption ofshell growth. Some of our samples differ from the holotypeby rare adapertural quadripartite bunches (2 per thewhorl).Measurements:ANo. D H W Du Wu Ia2 a.1 P Y95/15 32 14,5 9.5 9 2 20-25 -20 10 50 85-9095/11 23,5 - 12,4 3 35 -30 - - 9095/10 57.5 23,5 19,5 19 4 30 -30 20-25 10-15 8095/9* 110 44,5 34 36 8 10 -10 15 5 90* - measurements were made on a preserved part of the phragmoconeFig. 11 — Trends of change in the suture line in some Valanginianneocomitids based on the suture lines ofLuppovella (Neoluppovella) spinosa subgen. etsp. nov. - Text-Fig. 4.

ARGI 371/10 (Bogdanova collection).Suture line (Figure 8): Ventral lobe (V) is shorter thanthe trifid umbilical lobe (U), noticeably deviating towardsthe umbilicus. The first umbilical lobe (U 1 ) is only half asdeep as the umbilical lobe (U).The externa! and first lateral saddles are bifurcate andunequal. The external saddle is broader and shallowerthan the first lateral saddle.Remarks: The type of the species was chosen byUHLIG (1902; Hoplites campylotoxus, p, 49, pi. 4.fig. 2). VASICEK (1975: p. 90.' pi. VI, fig. 1) refiguredthis specimen and formally named it the lectotype.Hoplites campylotoxus (UHLIG, 1902: p. 49, pi. 4,fig. 3) and refigured by VASICEK (1975, p. 90: pi. VI,fig. 2) as Thurmanniceras cf. campylotoxum. shouldbe considered probably as a new species, because ithas very rare ribs and tubercles in the point of branching.There are very many references to this species in theliterature.Thurmannia (Kilianella) campylotoxa (COHEN. 1933:p. 163, pi. 2, fig. 11), Thurmanniceras campylotoxus(SAPUNOV. 1957: p. 158, pi. 3, fig. 7) and Thurmannia(Kilianella) campylotoxa (STEFANOV. 1934: p. 214. pi. 6,fig. 10, 11), Thurmannites cf. campylotoxus (ERISTAVI,1955: p. 91, pi. Ill, fig. 5), Thurmanniceras campylotoxum(NKOLOV. 1960: p. 178. pi. XX. fig. 3). Busnardoitescampylotoxus (MICHALIK & VASICEK, 1989: p. 513, pi, 1,fig. 1) belong mainly to Teschenites because of the presenceof tine ribbed inner whorls with weak umbilicaltubercles.Hoplites campilotoxus (sic) (LEMOINE, 1906: p. 180),Thurmannia (Kilianella) campylotoxa ( ACKFRMANN,1932; p. 42) and Thurmanniceras campylotoxum (ERISTA­VI, 1961: p. 95) were described without figuring, so exactidentification is impossible.Sarasinella aff. campylotoxa (SPATH, 1939: p. 103,pi, XXII, fig. 5a-b) according to the description, has threetubercles on ribs of the interna! whorls and cannot thereforebe referred to Campylotoxia.Sarasinella sp. aff. campylotoxa (COLLIGNON, 1962: p. 26.figs, 830, 831) belongs to different genera. The samplefigured on fig. 830, has fine, not flattened, weakly curvedribs and reminds one of Thurmanniceras. The weaklykeeled sample (fig. 831) has intercalated single and bifurcatingslightly curved ribs and possibly belongs toEristavites.Neocomites (Neocomites) campylotoxus (FATMI. 1977:p. 279. pi. 8. figs. 3, 4): the specimen in fig. 4 is almostidentical with Campylotoxia hrasseuri. and the specimenin fig. 3 has prevailing bipartite ribs and should referredto another species,Busnardoites campylotoxus (MICHALIK & VASICEK. 1989:
