New palynological and calcareous nannofossil records are presented for the Turonian–Coniacian boundary section at Salzgitter-Salder, Germany, candidate Coniacian GSSP. The proposed base of Stage is Bed 46, first appearance datum level Cremnoceramus deformis erectus, which coincident with a δ13C minimum top Navigation carbon isotope event. Palynological assemblages dominated by organic walled di...

The Coniacian-Santonian stages in western North America are characterized by a sparse fossil record. We present here the first account of dinosaur tracks from nine sites Frontier Formation (Coniacian-Santonian) southwestern Montana. Tracks largely preserved distal alluvial facies as sandstone casts, with single example shallow epirelief impression interpreted undertrack. Sandstone casts show si...

This study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the Coniacian–Santonian sediments of Tange-Bulfaris section. Five assemblage zones have been recognized by distribution of the foraminifera in the study area. Assemblage zone 1(Chara Ostracods zone) is Coniacian in age and occurs in the lower part of the succession. Assembl...

—A new species of aphroditiform polychaete, Protopholoe colombiana, is described from the Coniacian of Colombia, South America, increasing the number of species of this genus known from the fossil record to two. This is the first occurrence of fossil soft-bodied polychaetes in the Tropical Americas, and indicates that aphroditiforms were spread worldwide during the Mesozoic.

A specimen of Araucaria fricii is described from the upper part Teplice Formation in Bohemian Cretaceous Basin. It extends first occurrence A. mid-Coniacian back to early Coniacian. Found Radovesice locality near Kučlín northern Czech Republic, it characterised by a deltoid cone scale complex with centrally placed seed. compared type material Březno and other European species Araucaria. The tap...

A systematic account of crinoids from the Upper Coniacian-Lower Campanian of the southwestern margin of the Holy Cross Mountains in southern Poland is presented. Seven crinoid taxa [Marsupites testudinarius (von Schlotheim), Bourgueticrinus ellipticus (Miller), Bourgueticrinus sp., I.? granosus Valette, Isocrinus? sp., Nielsenicrinus carinatus Roemer and Austinocrinus bicoronatus (von Hagenow)]...

The Poigny borehole near Provins (Seine-et-Marne) provides the most complete single pristine section through Upper Cretaceous Chalk of Paris Basin. A well preserved and diverse palynoflora including 236 species subspecies organic-walled dinoflagellate cysts (dinocysts) is documented from borehole, together with a high-resolution carbon-isotope curve (δ 13 C carb ) for Coniacian–Campanian interv...

The Neolithic menhir El Gustal is located on a karstificated Coniacian limestone. The original morphology of the monolith and the pit has been preserved, and fragments of limestone filled the hollow. This has made it possible to identify construction phases of the most elementary stone constructive typology. Firstly, the original position of the monolith in the quarry of origin has been determi...

The Coniacian–Santonian time interval is the inferred time of oceanic anoxic event 3 (OAE 3), the last of the Cretaceous OAEs. A detailed look on the temporal and spatial distribution of organic-rich deposits attributed to OAE 3 suggests that black shale occurrences are restricted to the equatorial to mid-latitudinal Atlantic and adjacent basins, shelves and epicontinental seas like parts of th...
