    Opis:
    Several new specimens of ammonites from the Oxfordian and Kimmeridgian of Kachchh, western India, are described and illustrated. The Oxfordian ammonites ?Subdiscosphinctes Malinowska, Perisphinctes Waagen, Dichotomoceras Buckman, and ?Larcheria Tintant, all from Bharodia in the Wagad Uplift, enable tentative biochronostratigraphic correlations with the uppermost Middle Oxfordian up to the lower Upper Oxfordian of the unified Submediterranean zonation, whereas the Kimmeridgian ammonites Streblites Hyatt, “Orthosphinctes” Schindewolf, Torquatisphinctes Spath, Pachysphinctes Dietrich, Katroliceras Spath, Aspidoceras Zittel, and Schaireria Checa reconfirm a stratigraphic gap embracing incompletely known parts of the uppermost Oxfordian and the Lower Kimmeridgian as known from the ammonite records of the Kachchh Mainland of the Kachchh Basin.

    Oxfordian/Kimmeridgian boundary
    Opis:
    The Mikhalenino section on the Russian Platform has yielded numerous ammonites from the Middle and Upper Oxfordian and lowermost Kimmeridgian, collected bed by bed. The ammonites belong mostly to the Boreal family Cardioceratidae, but also to the Subboreal family Aulacostephanidae; additionally at some levels there were collected various Submediterranean ammonites (Perisphinctidae, Oppeliidae and Aspidoceratidae). The co-occurrence of ammonites representative of different faunal provinces makes possible recognition of the Boreal, Subboreal, and partly also Submediterranean standard zonations. In consequence, it is possible to make a close correlation between these zonal schemes. The Oxfordian/Kimmeridgian boundary at the Pseudocordata/Baylei zonal boundary of the Subboreal zonal scheme corresponds precisely to the Rosenkrantzi/Bauhini zonal boundary. This boundary of the stages defined well faunistically in the Flodigarry section (Isle of Skye, Scotland) and proposed as a candidate for the uniform Oxfordian/Kimmeridgian boundary, can be also recognized in the Russian section studied. The boundary can be traced in the Mikhalenino section using the same criteria as used at Staffin: the appearance of the first representatives of Pictonia [M]–Prorasenia [m] (Subboreal), and the first appearance of Amoeboceras (Plasmatites) (Boreal). This indicates the large correlation potential of the boundary defined in this way. The research on the Mikhalenino section has provided the new palaeontological findings described in this study. These include the first discovery in the territory of the Russian Platform of ammonites of the genera/subgenera Decipia, Vineta and Pomerania (Pachypictonia). Two new species: Decipia (?) kostromensis sp. nov., and Pictonia mesezhnikovi n. sp. are described.

    Opis:
    An extensive collection of ammonites made bed by bed from sections in the Submediterranean Upper Oxfordian of the Wieluń Upland, Central Poland, is described and used as a basis for a chronostratigraphical interpretation of the deposits. The ammonites are mostly of Submediterranean character and enable the recognition of the Bimammatum Zone, including the Bimammatum and Hauffianum subzones, as well as the lowermost Planula Zone distinguished here as a new biostratigraphical horizon – the matyjai horizon – based on the occurrence of Subnebrodites matyjai Wierzbowski et Głowniak sp. nov. The Submediterranean ammonites are mostly oppeliids with Taramelliceras (Taramelliceras) [M] – Glochiceras (Lingulaticeras) [m] the most numerous, as well as Taramelliceras (Richeiceras) and Taramelliceras (Metahaploceras) [M] – Glochiceras (Coryceras) [m]. The profusion of ammonites of these two groups in the stratigraphical interval studied provides new information on their evolution, and two new oppeliid species, Taramelliceras (Taramelliceras) zelcense Wierzbowski et Głowniak sp. nov. and Glochiceras (Lingulaticeras) bobrownikiense Wierzbowski et Głowniak sp. nov., are described here. Subboreal and Boreal ammonites are not common in these sections, but are nevertheless important for correlation. Subboreal ammonites of the family Aulacostephanidae are represented by the genus Vineta [M], including its newly recognized microconchiate counterpart, Vineta [m], and a newly established genus Vielunia [M] Wierzbowski et Głowniak gen. nov., with type species Vielunia dzalosinensis Wierzbowski et Głowniak sp. nov. The latter genus includes ammonites previously referred in the area of study to Ringsteadia, and with a microconchiate counterpart assigned to Prorasenia [m]. The Boreal ammonites comprise late cardioceratids assigned to Amoeboceras (Plasmatites). These ammonites indicate that the deposits in question from the Submediterranean Bimammatum Zone up to the Planula Zone correlate with the Subboreal and Boreal lowermost Kimmeridgian (Baylei Zone, and Bauhini Zone, respectively).
