“…A larger form, 2-3 mm in diameter, and smaller form, up to 1 mm diameter, can be distinguished. Limited observations along the tunnels preclude more detailed determinations, however taking into account the size parameters (Uchman, 1999), the smaller form can belong to Chondrites intricatus (Brongniart, 1823) and the larger one to Chondrites targionii (Brongniart, 1828). The smaller form can be found in the fillings of some Thalassinoides or Planolites.…”

In this paper we present the effects of different tracemakers on the redistribution of calcareous nannofossils throughout the K-Pg boundary at the Bidart section (SW France), along with their consequences for our knowledge of the K-Pg boundary event. Danian calcareous nannofossil assemblages are present in Maastrichtian samples due to infiltration into dark trace fossil infillings proceeding from the earliest Paleogene. This is evidenced by the appearance of abundant paleogene calcareous nannofossils just below the K-Pg boundary, showing the relevance of the trace fossil infillings in the context of the K-Pg boundary event. # 2010 Elsevier Masson SAS.

Des assemblages de nannofossiles typiquement daniens sont présents dans des échantillons du Maestrichtien, remaniés par infiltration, dans des remplissages de couleur sombre de traces fossiles formées au début du Paléogène.

Paleoecological significance of the trace fossils of Dhosa Oolite Member (Jumara Formation), Jhura dome, Mainland Kachchh, Western India

Dhosa Oolite Member of the Jumara Formation comprises alternating bands of oolitic limestones and shales, exposed in Jhura dome of Mainland Kachchh, Western India. This sequence is highly bioturbated and exhibits a moderate diversity and behaviourally complex assemblage of ichnospecies. The rhythmically bedded sequence shows three different levels of preservation of traces. Epichnial tiering consists of moderately bioturbated oolitic limestone exhibiting horizontal or low-angle protrusive/retrusive biogenic laminae, commonly dominated by feeding structures like Rhizocorallium jenense, R. irregulare, Zoophycos brianteus and Zoophycos isp. The endichnial structures within the oolitic limestone can be separated into two different preservational trace fossil suites. The endichnial shallow suites consist chiefly of deposit feeders like Chondrites intricatus, C. targionii, Planolites beverleyensis, Taenidium cameronensis, Thalassinoides isp., Z. brianteus, Z. cf circinnatus and Zoophycos isp. and few suspension feeder forms like Palaeophycus tubularis; while endichnial deep suites consist of Chondrites intricatus, Skolithos linearis and Zoophycos isp. Hypichnial structures consists abundant, cylindrical, branched, horizontal, large-sized three dimensional feeding burrows of Thalassinoides isp. and somewhat irregular, obtuse angle ramification burrows of Phycodes isp., which are attached to the lower surface of the casting medium. The trace fossil association indicates Cruziana ichnofacies and abundance of Zoophycus species below the fair weather wave base level is largely a preservational artifact. The preservational processes of the trace fossils indicate soft substrate and diversity and their abundance reflects the other palaeoecological parameters of the open shallow marine environments.

“…For example, Stoneley (1958) described late Permian ginkgophyte remains from England as Sphenobaiera digitata (Brongniart) Florin, 1936 although the leaves have a distinct petiole. Also the petiolate ginkgophyte remains from the Kupferschiefer of Germany initially described as Baiera digitata Brongniart, 1828 were later variously referred to Sphenobaiera digitata (e.g., Haubold & Schaumberg 1985). Harris & Millington (1974) emended the diagnosis of Florin (1936a) to include more or less broadly wedge-shaped leaves that are "shed separately".…”

Ginkgophyte foliage fossils (impressions and compressions lacking cuticle) from several of the historical Kupferschiefer localities in Germany have been re-studied using macromorphometry. Baiera digitata is by far the most common ginkgophyte in the Kupferschiefer, while other taxa are relatively rare. A new taxon, for which the name Baiera mansfeldensis is proposed, differs from B. digitata in having a much thinner, curved petiole and a curved lamina, as well as a narrow basal angle. Esterella gracilis, a taxon previously known exclusively from France, is reported for the first time from Germany. The foliage genera Baiera and Sphenobaiera have a complicated taxonomic history, and the problematic contiguity that exists between the two taxa has lead to considerable confusion. It appears that the radiation of the ginkgophytes started well before the end-Permian mass-extinction, and that Permian ginkgophytes were more diverse than previously believed.•
