“…Separation between the Pomatoschistus line and that forming the precursor for the two other genera may be envisaged to have occurred in the middle Miocene Serravalian (12-14 mya), with enclosure of the brackish Sarmatic Sea and the beginning of the evolution of the Ponto-Caspian endemic fauna (Steininger & Rogl, 1984), involving onset of canal loss in the latter line. Separation between Knipowitschia and Economidichthys may be linked with the Upper Miocene Messinian salinity crisis, affecting the Mediterranean basins from about 6.5 mya (Van Couvering et al, 1976), and noted for the Ionian Basin in particular by Fabricius (1984). With elimination of more stenohaline marine Pomatoschistus under hypersaline evaporative conditions, the spread of euryhaline Sarmatic fauna into the eastern basin may have become possible, and the pre-existing physiological capability to tolerate euryhaline conditions, noted in most recent Knipowitschia, would have favoured this process (Mordukhai-Boltovskoi, 1964).…”

Five species of gobiid fish are recognized in the fresh waters of Greece. Most distinctive is the south‐western Hellenic (West Balkanian component) endemic genus Economidichthys Bianco, Bullock, Miller & Roubal, 1987, with the type‐species E. pygmaeus (Holly, 1929) from Lefkas, Epirus and Lake Trichonis, and E. trichonis sp. nov., from Lake Trichonis, the latter probably the smallest freshwater European teleost at maturity (female, 18·0 mm) and maximum size (male, 30·0 mm). In tributaries of the northern Aegean basin (north‐eastern Hellenic freshwater fauna), two species of the Ponto‐Caspian genus Knipowitschia can be identified, the widespread Kn. caucasica (Kawrajsky in Berg, 1916) (coastal plain of Macedonia and Thrace) and the endemic Kn. ihessala (Vinciguerra, 1921) (Pinios river system, Thessaly). The larger Ponto‐Caspian tubenose goby, Prolerorhinus marmoratus (Pallas, 1811), occurs in the Evros (= Maritsa) (Thrace) and Strymon (Macedonia) systems. Only the genera Economidichthys and Knipowitschia are considered in this paper, being redefined in terms of osteology and head lateral‐line system, and the species described in detail, with special reference to meristic variation and squamation, and, in Economidichthys, the unique perianal organ of this genus. The relationships of Economidichthys and Kn. thessala are discussed and possible scenarios for their evolution are suggested in the light of Miocene to Recent events.

“…The timing of inversion is restricted to latest Miocene (Tortonian) in relation with a plate reorganization preceding the main phase of opening of the Tyrrhenian Basin (Chamot-Rooke, Rangin, et al, 2005;Gallais et al, 2011), and probably not Late Cretaceous to Paleogene as suggested by Roure et al (2012). The same structures were interpreted as Late Miocene tilted blocks evidencing extension of the African plate (e.g., Hieke et al, 2003Hieke et al, , 2009), suggesting very recent formation of the basin (Fabricius & Hieke, 1977;Fabricius, 1984; Figure 2).…”

We revisit the nature, structure, and evolution of the Ionian Basin and its surrounding passive margins (Apulia, Eastern Sicily/Malta, and Cyrenaica margins). Relying on geological observations (wells, dredges, and dives) and seismic calibrations from the surrounding platforms and escarpments, we present age correlations for the deepest sedimentary sequences of the Ionian Basin. Two‐ship deep refraction seismic data combined with reprocessed reflection seismic data enable us to identify, characterize, and map these thick sedimentary sequences and to present a consistent seismic stratigraphy across the basin. At a larger scale, we present new geological transects illustrating the tectonostratigraphic relationships between the Ionian Basin and its surrounding rifted margins. On this basis, we suggest that a Late Triassic‐Early Jurassic rifting preceded the late Early Jurassic to Middle Jurassic formation of the Ionian Basin. The combination of geophysical and geological arguments suggests that the entire deep basin is floored with oceanic crust of normal thickness, but with high seismic velocity in the upper part. Upscaling our results in the framework of the eastern Mediterranean, we propose that the Ionian Basin represents the remnant of a short‐lived oceanic basin resulting from the interaction between two propagating oceans: the Central Atlantic and the Neo‐Tethys.

The late Tertiary subsidence history of the southern Levant continental margin, situated in the southeastern Mediterranean Sea, was quantitatively analyzed. Paleodepth reconstruction across the margin off Ashdod suggests the existence of a deep basin in pre‐Messinian time which resembles the present one. This implies that, the deposition of the evaporites in the study area during the Messinian desiccation of the Mediterranean Sea occurred in a deep basin. The path of the tectonic subsidence of the basement since early Tertiary is generally smooth as expected from the nature of the thermal subsidence. The unconformity beneath the Messinian indicates erosion of 50–200 m at the coastal plain. In the Pliocene, the tectonic subsidence in the coastal plain and shelf area diverts from the expected thermal path and increases from 250 m to 450 m, respectively. In the Quaternary the rate of tectonic subsidence nearly resumed the predicted thermal subsidence. Sedimentation and subsidence rates decrease but are still higher than those of the pre‐Messinian. We suggest that the evolution of the southern Levant margin is most probably influenced by three main causes: (1) the Messinian event in late Miocene, (2) the deposition of large volumes of Nile derived sediments since the Pliocene, and (3) the flexural response of the lithosphere to the load from the Nile delta and/or from the uplift of the Judea Mountains (the western shoulder of the Dead Sea Transform). We interpret the latter to be the cause of the anomalous subsidence of the southern Levant margin during the Pliocene.
