“…Mean size diameter (Mz) and sorting (Sort), expressed in φ (phi), were determined using the Folk and Ward formulas (Folk and Ward, 1957 Giannuzzi-Savelli et al , 1997-2003) as well as contributions more specifically devoted to the East Mediterranean faunas (Pallary, 1911;Danin, 1982, 1992). As for the palaeoenvironmental interpretation, the molluscan assemblages have been interpreted according to the Mediterranean benthic bionomy of Pérès and Picard (1964), Picard (1965), and Pérès (1982) and according to contributions on Mediterranean ecology and palaeoecology (Bernasconi et al, 1991;Bernasconi and Robba, 1993;Bernasconi and Stanley, 1997). Molluscan assemblages have been identified in 19 out of 23 examined samples; they are more diversified (either for number of species or number of specimens) in the mid-lower sector of the core, between ~7 and 13 m; in the mid-upper core, molluscs are represented by 1 or 2 species, attaining a maximum of 3 specimens per sample; the whole specimens are generally associated with a large amount of fragmented, unidentifiable shell material.…”

The ancient site of Elaiussa Sebaste (SE coast of Turkey) was one of the main trading harbours of the Mediterranean, growing in the Augustan period and maintaining its prestige until the Byzantine era. The Arabic invasion that occurred in the second half of the 7th century AD marked its definitive abandonment. A very prominent historical topic concerns the palaeoenvironmental evolution of the northern and southern harbours of Elaiussa Sebaste, including their decline and burial. A wide interdisciplinary study plans to analyse 8 cores drilled in the modern plains, which correspond to the setting of the 2 harbours basins. This geoarchaeological investigation aims to provide a first model of the environmental evolution recorded in the northern port basin, obtained by means of litho-and biofacies analyses from one of the 8 cores (ELA6) that best represents a good reference-succession in order to interpret this evolution. It consists of sediments deposited in a timespan from the 2nd century BC to the 6th century AD, corresponding to the developments of the ancient town and its harbours. The geophysics evidences the depth of the bedrock and the overlaying deposits. Sedimentology, macropalaeontology, and micropalaeontology define a sequence of shallow marine palaeoenvironments, with clear influence of fresh water. The palynology focuses the attention on a short core-interval corresponding to the timespan of 150-190 AD approximately, when the human impact might have controlled this evolution by building and cultivating. A hypothetical scenario might link some natural events (i.e. the uplift of the area, the increase of the sedimentation rate) to the human impact. These causes may have resulted in the siltation of the harbour that finally ended all harbour-related activities. During the timespan of the 2nd century BC to the 4th century AD, the northern harbour of Elaiussa-Sebaste may represent a good test to apply the Ancient Harbour Parasequence.

“…As discussed by Basso and Corselli (2002), the conceptual framework based on communities appears to oversimplify the picture of the most important ecological units in the Mediterranean benthos. The benthic bionomy that derives from a qualitative approach (Pérès and Picard, 1964) has been successfully adopted for ecological, as well as palaeoecological studies in the Mediterranean area (e.g., Bernasconi and Robba, 1993;D'Alessandro and Massari, 1997;Di Geronimo and La Perna, 1997;Basso and Corselli, 2002). The recent age of the studied deposits allows to use the qualitative approach for a more detailed reconstruction of palaeoenvironments.…”

“…1A'). This Pliocene outcrop has been well known since the 20 th century thanks to its rich mollusc faunas (mainly gastropods) as documented by several studies (e.g., Bernasconi & Robba 1984, 1994Solsona & Martinell 1999;Andri et al 2005;Harzhauser & Kronenberg 2008). Published micropalaeontological data (Violanti 1987;Mancin et al 2012) pointed out the depositional environment of the Rio Torsero section, which probably recorded the sedimentation in the circalittoral zone, close to the shelf edge.…”

Abstract:The occurrence of agglutinated foraminiferal specimens belonging to the Badenian (middle Miocene) genus Colominella Popescu, 1998 was recently documented for the first time in a lower Pliocene succession of the western Mediterranean area. Direct comparisons with topotype specimens of Colominella paalzowi (Cushman 1936), sampled in the Badenian type section of Lăpugiu de Sus (Transylvania), show that the Pliocene individuals from the western Mediterranean morphologically resemble the type species C. paalzowi, but they also differ in possessing a longer biserial chamber arrangement with a higher number of internal chamber partitions, in lacking a clear early triserial stage and in having a more complex microstructure of the agglutinated wall, thereby supporting the idea that the Pliocene Mediterranean specimens represent a new, more highly evolved species. The fact that the Pliocene individuals from the Mediterranean appear to be more evolved with respect to the Badenian specimens from Paratethys represents an interesting evolutionary development of the genus Colominella that also permits the known stratigraphical and geographical range of the genus, previously limited to the middle Miocene (Badenian) of the Paratethys, to be extended.
