“…The smaller specimens in the Botellos assemblage correspond to the Cerralvo specimens in every detail, but the Botellos assemblage yields four larger specimens, which already bear ornament consisting of six primary ribs per half whorl. These characteristics, the initial diameter and the number of ribs, are similar to the juvenile ornament of the specimens described in detail by Henderson and McNamara (1985). Secondaries are intercalated from a quarter whorl later on.…”

“…Secondaries are intercalated from a quarter whorl later on. They number eight per quarter whorl in the Botellos specimens, which also matches the density described by Henderson and McNamara (1985). The larger Botellos specimens thus close a gap in documented growth stage between the small ones preserved in other localites of the region (Ifrim et al 2005; and known growth stages of P. (P.) neubergicus (von Hauer, 1858).…”

“…50 km SSE of the Botellos locality, relate to the group of P. (P.) neubergicus (von Hauer, 1858). The species P. (P.) neubergicus sensu stricto displays smooth early growth stages up to a diameter of about 25 mm (Henderson and McNamara 1985). Its whorl section is very similar to that of the Botellos specimens with respect to whorl dimension.…”

ABSTRACT:Ifrim, C., Lara de la Cerda, J.E., Peña Ponce, V.H. and Stinnesbeck, W. 2017. The Upper Campanian -lower Maastrichtian cephalopod fauna of Botellos, Nuevo León: a key to understand faunal turnover across the Campanian-Maastrichtian boundary in NE Mexico. Acta Geologica Polonica, 67 (1), 145-162. Warszawa.A new cephalopod collection from the Campanian-Maastrichtian boundary interval of NE Mexico, consisting of 1076 individuals assigned to 29 species and 22 genera is presented. This collection is a mix of ammonoids, one coleoid and one nautilid, which originate from at least three ammonoid biozones: The upper Campanian Exiteloceras jenneyi and Nostoceras (Nostoceras) hyatti zones, and the lower Maastrichtian Pachydiscus (Pachydiscus) neubergicus Zone. The age of the collection is thus middle late Campanian to late early Maastrichtian, and it closes a stratigraphic gap between faunas described formerly from this region. The specimens are nuclei collected from the desert pavement. The abundance of specimens allows for a comparison to other Campanian-Maastrichtian ammonoid records from Mexico, North America and Europe.

“…6). Contrary to Kennedy and Henderson (1992) and Henderson et al (1992), D. maximum is here regarded as a valid species by virtue of the distinctive ribbing pattern of its growth stages with whorl height equalling or exceeding 55 mm (Olivero and Zinsmeister 1989, Text-fig. 6).…”

Stratigraphically important ammonites from the Campanian–Maastrichtian boundary interval of the Middle Vistula River section, central Poland

Machalski, M. 2012. Stratigraphically important ammonites from the Campanian-Maastrichtian boundary interval of the Middle Vistula River section, central Poland. Acta Geologica Polonica, 62 (1), 91-116. Warszawa. The formal definition of the Global Stratotype Section and Point (GSSP) for the base of the Maastrichtian Stage at Tercis, southwest France, is based on the first or last occurrences of twelve taxa, including three species of ammonites, Pachydiscus (Pachydiscus) neubergicus, Diplomoceras cylindraceum, and Nostoceras (Nostoceras ) hyatti. The taxonomy and stratigraphical distribution of these, and allied forms, are studied, on the basis of material from the opoka succession across the upper Campanian-lowermost Maastrichtian boundary in the Middle Vistula River section, central Poland. In view of the imprecise location of two ammonite GSSP markers in that section, a direct ammonite-based correlation with the GSSP at Tercis is impossible. However, data available indicate that in the Middle Vistula River section the first occurrence of Pachydiscus (P.) neubergicus and the last occurrence of Nostoceras (N.) hyatti are situated significantly higher than the first occurrence of Belemnellalanceolata, the traditional belemnite marker for the base of the Maastrichtian Stage in the Boreal Realm, and that Diplomoceras cylindraceum appears significantly below this level. There are no unequivocal records of Pachydiscus (P.) neubergicus from the Belemnella lanceolata Zone s.l. in the Middle Vistula River section.
