“…These are below grey marl beds with two charophyte species of the genus Septorella (Brinkmann, 1984;Masriera & Ullastre, 1988). Septorella brachycera disappears within the early Chron C31n (Galbrun et al, 1993;Riveline et al, 1996; about 68.5 Ma according to Cande & Kent, 1995), just below the Abathomphalus mayaroensis datum (Pujalte et al, 1995; Figure 3); thus these sites cannot be younger than early Late Maastrichtian.…”

Six new dinosaurs sites have been found close to the Cretaceous/Tertiary boundary in Arén (south-central Pyrenees, Huesca, Spain) in coastal and non-marine deposits of the Arén and Tremp Formations. The sites contain articulated remains (skull elements, vertebrae, hind-limb bones) and isolated teeth and bones of hadrosaurids, three types of theropod teeth, one sauropod, at least seven types of eggshells (six ornithoid types and one Megaloolithidae probably from a sauropod), remains of other vertebrates, and four charophyte species. The fossil-bearing rocks have been correlated with marine sediments containing planktonic foraminifera from the uppermost Maastrichtian Abathomphalus mayaroensis Biozone. These rich and diversified dinosaur assemblages enable more accurate dating of the faunal changes that took place during the Maastrichtian in Europe and support the hypothesis of a sudden dinosaur extinction at the Cretaceous/Tertiary boundary.

“…In the Fontllonga section, the K-T boundary occurs within a 1-to 3-m thick lutite interval near the top of a thick sandstone unit correlated with Chron C29r (Galbrun et al 1993). Dinosaur remains are common below this interval but disappear just above it, where a ~13C isotopic anomaly indicates a marked change in organic productivity.…”

The palynological record across the Cretaceous-Tertiary boundary in differing palaeogeographical settings from the southern Pyrenees, Spain

North American and Pacific spore-pollen records show a major extinction event at the Cretaceous Tertiary (K-T) boundary, and abrupt changes are similarly found in many marine organisms world-wide. In contrast, records from the Old World reveal little evidence of terrestrial vegetational change across the boundary. In order to improve the characterization of changes across the K-T boundary, palynological assemblages from two sections in the southern Pyrenees have been evaluated. The abundance and diversity of trilete fern spores are high in Maastrichtian samples and show a statistically significant decrease during the Danian. The 'fern spike' of low-diversity spores found elsewhere is not recorded in the Pyrenean region. Minor replacements of taxa across the K-T boundary are also noted, as well as an increase in inaperturate gymnosperm pollen in the Danian. Comparing our two examined sections with one another reveals important differences in angiosperm pollen composition.

Charophyte assemblages from the mid‐Campanian and lower Paleocene of the SK‐1(North) borehole in the Songliao Basin (NE China) are here re‐studied. Four charophyte biozones and one superzone are defined in the Sifangtai and Mingshui formations and correlated to the Geomagnetic Polarity Time Scale. These include a mid–late Campanian Atopochara trivolvis ulanensis Zone, a latest Campanian – early Maastrichtian Microchara gobica Zone, a late Maastrichtian Microchara prolixa Zone, and an earliest Danian Peckichara sinuolata Zone. The latter three zones are grouped within the Microchara cristata Superzone, which allows intra‐ and intercontinental correlation with other basins in China and Europe. Peckichara sinuolata first appears in chron C29r (upper Mingshui Formation) and is proposed as the basal marker of the Paleocene. The biozonation of the K/Pg interval proposed for the Songliao Basin differs from a previous biozonation proposed in the Pingyi Basin since it represents a different biogeographical and palaeoecological context. In the mid‐Campanian to Maastrichtian, the flora was limited to freshwater lakes in northern China and Mongolia, whereas in the Pingyi Basin, brackish water dominated. In the Paleocene, the Songliao Basin contained a diverse flora consisting of nine species that thrived in terrigenous and temporary lakes, whereas the flora in the Pingyi Basin was dominated by one species inhabiting permanent alkaline lakes. The species common to the two basins are widely distributed in Eurasia and constitute a useful tool for long‐distance correlations, but serve as a less‐precise tool for detailed biostratigraphical subdivision within one specific basin.
