Description: There are two collected specimens in the material, both worn out on one side. The bigger is of ca. 83 mm in diameter, the smaller one is ca. 57 mm. Both specimens are wholly septate and preserve some recrystallized shell. The umbilicus is narrow, the periumbilical sides form funnel-shape depression. The flanks are moderately convex, the venter is broadly arched.The parts of lacking the shell on the bigger specimen show the periumbilical rosette formed by shallow, projected constrictions, which disappear around the middle of the whorl-sides. On the upper part of the flanks and on the venter the labial ridges are clearly visible. Entire suture lines cannot be seen. Remarks : P. flabellatum , the type of which came from the Bathonian of Swinitza (Romania), is a common element in Mediterranean Bathonian and Callovian faunas. It was described from Sicily by GEMMELARO (1872, p. 172, pl. II, figs 1-2), under the name P. euphyllum , and recorded by ARKELL (1954, p. 278) and WENDT (1963) in several faunal lists. Suborder AMMONITINA Hyatt, 1889 Superfamily H ap 1 oc e r at ac e ae Zittel, 1884 Family Oppeliidae Bonarelli, 1894 Subfamily Hecticoceratinae Spath, 1925 Genus Prohecticoceras Spath, 1928 Prohecticoceras haugi (POPOVICI-HATZEG, 1905) (Plate II, Figs 2a-b) 1905. Hecticoceras haugi n. sp. — POPOVICI-HATZEG, p. 18, pi. 4, fig. 3; pi. 5, figs 2-10. 1972. Prohecticoceras haugi (POPOVICI-HATZEG) ~ KRYSTYN, p. 244, pi. 6, fig. 1; text-fig. 1. ( cum syn. ) Description: A single, well-preserved internal cast with recrystallized shell. The specimen is septate up to the greatest preserved diameter (72 mm), where the measurements are: 40 (55.5%); 21 (29%); 10 (14%). The coiling is very involute, the narrow umbilicus has high, perpendicular walls and rounded umbilical margin. The whorl-section is high-triangular, with flattened flanks and slightly elevated, double spiral band at the lower third of the whorl-height. The venter is narrow, tectiform, with a blunt keel. The ribbing consists of short blunt primary ribs on the inner part of the flank, and curved rursiradiate secondaries on the outer whorl-sides. The secondaries end in strengthened terminations on the ventrolateral margin. The first half of the last preserved whorl bears 10 primary and 31 secondary ribs. The primary and secondary ribbing starts fading at ca. 47 mm diameter, with weakening of the primaries and disappearing of the stems of some secondaries. Certain surviving secondary ribs apparently remain at greater diameters, but the preservation does not allow one to see them clearly. No suture line can be seen. Remarks : P . haugi is a characteristic ammonite in Middle and basal Upper Bathonian faunas,with maximal abundance in the Hodsoni Zone (Retrocostatum Zone auctt.; see TORRENS, 1971). Howe ver, the type (POPOVICI-HATZEG, 1905, pl. V, figs 8a-c) came from the Strunga fauna (Romania), which is a condensed material of mainly deeper Bathonian elements. The genus Prohecticoceras is commonly represented in Bathonian faunas from Sicily. ARKELL (1954) recorded several species from Monte Bonifato, and WENDT mentioned other occurrences in Monte Erice (1963, p. 68; 1971, p. 60). Family Lissoceratidae Douvillé, 1885 Genus Lissoceras Bayle, 1879 Lissoceras (Lissoceras) ferrifex (ZITTEL, 1868) (Plate I, Figs 5a-b) 1868. Ammonites ferrifex n. sp. -- ZITTEL, p. 604. 1980. Lissoceras ferrifex (ZITTEL, 1868) — GALÁCZ, p. 60, pl. XHI, fig. 1; text-figs 47-48. (cum syn. ) Description: This well-preserved, medium-sized ammonite is an entirely septate phragmocone with preserved recrystallized shell. It measures, at 58 mm diameter: 28 (48%); 23 (40%); 8.5 (15%).
