Eleven ammonites species are described from the condensed phosphate beds of Mangyshlak (in north-western Kazakhstan): Lewesiceras mantelli (Wright and Wright, 1951), Subprionocyclus neptuni (Geinitz, 1849), Prionocyclus spp., Allocrioceras angustum (J. de C. Sowerby, 1850), Hyphantoceras ( Hyphantoceras) reussianum (d’Orbigny, 1850), Hyphantoceras ( Hyphantoceras) cf. flexuosum (Schlüter, 1872), Eubostrychoceras ( Eubostrychoceras) cf. saxonicum (Schlüter, 1875), Scalarites? bohemicus (Fritsch, 1872), Sciponoceras bohemicum bohemicum (Fritsch, 1872), Scaphites geinitzii d’Orbigny, 1850, and Scaphites kieslingswaldensis Langenhan and Grundey, 1891. They provide an incomplete record that spans at maximum upper Middle Turonian to Lower Coniacian and at minimum Upper Turonian to Lower Coniacian. Associated inoceramid bivalves span an interval from upper Middle Turonian (based on the known first occurrence of Inoceramus inaequivalvis Schlüter, 1872) to the lower and middle Lower Coniacian, based on the known last occurrence of Cremnoceramus crassus inconstans (Woods, 1912), in the lower and middle parts of the Lower Coniacian.

The lower Upper Albian ammonite genus Dipoloceras Hyatt, 1900 (subfamily Mojsisovicsiinae Hyatt, 1903) is represented in KwaZulu-Natal by the type species, D. cristatum (Brongniart, 1822), marker species for the base of the Upper Albian Substage. Rhytidoceras van Hoepen, 1931 (of which Drepanoceras van Hoepen, 1931, non Stein 1878 and Ricnoceras van Hoepen, 1941, are synonyms), previously regarded as subgenera of Dipoloceras, are afforded generic status as are its supposed synonyms Diplasioceras van Hoepen, 1946a, and Euspectroceras van Hoepen, 1946a. The type species of these genera are revised, and assigned to the subfamily Pervinquierinae Spath, 1926.

The cosmopolitan Late Albian ammonite subgenus Pervinquieria ( Deiradoceras) van Hoepen, 1931, and its synonyms Cechenoceras van Hoepen, 1941 and Mimeloceras van Hoepen, 1944, originally based on material from northern KwaZulu-Natal, are reviewed. The type material of the type species, Subschloenbachia prerostrata Spath, 1921, is revised and reillustrated, as are its numerous synonyms.

In this contribution we complete the revision of species we refer to Pervinquieria ( Deiradoceras) van Hoepen, 1931, focusing on those assigned by him to his genera Cechenoceras and Mimeloceras.

Upper Cretaceous ammonites are described from six horizons in the mammal-bearing terrigenous-clastic sequences of western Uzbekistan, as follows: Upper Cenomanian, with Placenticeras sp. juv. cf. cumminsi Cragin, 1893 and Metoicoceras geslinianum (d’Orbigny, 1850); Lower Turonian with Tragodesmoceras cf. mauryae Kennedy and Wright, 1981, Placenticeras kharesmense (Lahusen, 1884), Watinoceras coloradoense (Henderson, 1908), Watinoceras amudariense (Arkhangelsky, 1916b), Metasigaloceras rusticum (J. Sowerby, 1823), Morrowites wingi (Morrow, 1935), Sciponoceras cf. bohemicum bohemicum (Fritsch, 1872), and Yezoites amudariensis (Arkhangelsky, 1916b); Middle Turonian with Collignoniceras woollgari woollgari (Mantell, 1822); Upper Turonian with Lewesiceras mantelli (Wright and Wright, 1951) and Placenticeras crassum Ilyin, 2020; a single Placenticeras semiornatum (d’Orbigny, 1850) from around the Coniacian/Santonian boundary, and Santonian Placenticeras polyopsis (Dujardin, 1837).
