Planktonic foraminiferal biostratigraphy of the studied carbonates revealed that the investigated part of the Gardiki section covers the Cretaceous–Paleogene (K-Pg) transition, partly reflecting the Senonian limestone and calciturbidites formations of the Ionian zone stratigraphy. Litho-and bio-facies analyses allowed for the recognition of three distinct depositional facies: (a) the latest Maastrichtian pelagic biomicrite mudstone with in situ planktonic foraminifera, radiolarians, and filaments, (b) a pelagic biomicrite packstone with abundant planktonic foraminifera at the K-Pg boundary, and (c) an early Pa...

DESCRIPTION Small conical, hollow and rather elongated conescharelliniform colonies. Hexagonal zooids arranged in alternating radial series. Smooth convex frontal. Pear-shaped aperture with a large anter separated by two strong cardelles from a smaller poster. One or two well-developed oval avicularia are generally present on the lateral sides of the zooid. Ovicell not observed. REMARKS As noted by several authors (e.g., Zágoršek 2003), the avicularia are more or less developed and may either occur in pairs, or alone, or lack completely. The ovicells have rarely been observed.

Recent: eastern Atlantic and Mediterranean from the surface to 150 m (and down to 500 m in the Gulf of Gascony: Jullien & Calvet 1903). DESCRIPTION Cellariiform colony.Internodes comprising two alternating series of zooids. Gymnocyst smooth. Oval opesia occupying slightly more than half of the zooecial length with two large septula in the distal part of the opesial margin Five spine bases on the distal rim (three on the outer edge and two on the inner part), accompanied by one slightly larger scutal basis on the internal edge. The scutum itself, rarely preserved, is rather large and its proximal lobe is more developed. Prominent triangular lateral avicularia. When present, the frontal avicularia are small and always located near the internal distal part of the ovicells, which are rounded, smooth and exhibit a small proximal fenestra. Dorsal surface with small triangular vibracularia. REMARKS The number of spine bases is relatively constant, but one of them, on the distal rim, is occasionally lacking. Only two spines are observable on ovicellate zooids.

OCCURRENCE. — Recent: Eastern Atlantic (50-60 m in the North Sea, much deeper in Norway, the Bay of Biscay and Morocco: 135- 1000 m) and Mediterranean (115-480 m). DESCRIPTION Cellariiform colony. Internodes short (8-12 zooids). The first ramification arises from the third zooid. Pseudopores elongate and relatively rare. Gonozooid pyriform with a discrete ooeciostome situated near the base of the following zooid. REMARKS This species is poorly known and has rarely been illustrated. It has often been considered as a variety of C. eburnea (Linnaeus) to which it resembles. Harmelin (1990) distinguished a northern (Atlantic) and a southern form (Atlantic coast of Morocco, Mediterranean). The main differences are a higher number of zooids (9-12) per internode and a mitre-shaped gonozooid in the southern form.
