Miocene decapod crustacean faunas from Cyprus – Part 1. Geographical-stratigraphical setting and Anomura

“…Two species have been collected from both members; Galathea weinfurteri and Petrolisthes magnus. This does not come as a surprise as far as the former taxon is concerned because this is a common and widespread species with an extensive stratigraphical range (Oligocene to Messinian) (Müller 1984a(Müller , b, 1993(Müller , 1996Radwański et al, 2006;De Angeli et al, 2010;Gatt and De Angeli, 2010;Ossó and Stalennuy, 2011;Hyžný and Dulai, 2021;Ossó et al, 2022). Petrolisthes magnus is known exclusively from the Middle Miocene of Hungary and Ukraine (Müller, 1984;Radwański et al, 2006;Ossó and Stalennuy 2011;Górka, 2018;Hyžný and Dulai, 2021) and possibly from the Messinian of Malta (Gatt and De Angeli, 2010).…”

“…Remarks. This common and widely distributed species has been recorded to date from Miocene levels in the Paratethys: Austria, Hungary, Poland and Ukraine -see Müller (1984aMüller ( , b, 1993Müller ( , 1996, Radwański et al, (2006) and Ossó and Stalennuy (2011), as well as from the Oligocene of northern Italy (De Angeli et al, 2010), the Middle Miocene from France (Ossó et al, 2022) and the Upper Miocene of Malta (Gatt and De Angeli, 2010).…”

“…From several of these reefal deposits decapod crustaceans have been recorded in recent decades (e.g., Müller, 1984bMüller, , 1993Georgiades-Dikeoulia and Müller, 1984; Garcia Socias, 1990;Gatt and De Angeli, 2010;De Angeli et al, 2011, Ossó andHammann-Yelo, 2021). Interestingly, decapod crustacean faunas from such strata exhibit marked taxonomic similarities to those from the Central Paratethys (e.g., Müller, 1984a;Górka, 2002;Radwański et al, 2006;Ossó and Stalennuy, 2011;Collins, 2014;Hyžný and Dulai, 2021) and even those from the Pacific region (e.g., Müller, 1979Müller, , 1984aDe Angeli et al, 2011;Ossó and Gagnaison, 2019;Ossó et al, 2022).…”

Review of brachyuran crabs from the late Miocene (Messinian) of Oran, Algeria

“…This species was later synonymized with Cancer sismondai Meyer, 1843 by Ristori (1886). This synonymy and the placement in Lobocarcinus Reuss, 1857, was discussed by several authors through the 20th century (e.g., Van Straelen 1937; Bonfiglio & Donadeo 1982) until Ossó et al (2022). All the Algerian specimens assigned to deshayesii or sismondai are currently in review by the authors and will be the subject of a future publication.…”

Nouvelles données géologiques et biostratigraphiques du gisement paléontologique à vertébrés de Mauvières, à Marcilly-sur-Maulne (Miocène inférieur et moyen; Indre-et-Loire, France)

“…Les galets calcaires, issus de l'érosion des formations jurassiques, crétacées et paléogènes, sont perforés par des bivalves lithophages. Ils sont mélangés avec un sable bioclastique contenant de nombreux débris de mollusques, majoritairement de grands pectinidés et des ostréidés, issus d'un milieu tidal à infralittoral supérieur (Courville & Bongrain 2003; Ossó et al 2022). De grandes lamines obliques tangentielles sont visibles donnant un sens de courant globalement vers le Nord-Ouest.…”
