Piacenzian–Gelasian non‐marine ostracods from the Dunarobba Fossil Forest (Tiberino Basin, Umbria, central Italy)

Abstract

The taxonomy of some non‐marine ostracod assemblages from the Dunarobba Fossil Forest area (south Tiberino Basin, Umbria, Italy) is discussed, adding to the scientific understanding of Piacenzian–Gelasian non‐marine ostracods in central Italy and providing a palaeoenvironmental reconstruction of the shallow coastal lacustrine environments of the Palaeolake Tiberino. The ostracod assemblages include Darwinula stevensoni, Vestalenula cylindrica, Candona (Candona) improvisa, Candona (Neglecandona) neglecta, Candona (Neglecandona) angulata, Candona (Neglecandona) paludinica, Caspiocypris basilicii, Caspiocypris tiberina, Candonopsis kingsleii, Cyclocypris ovum, Ilyocypris bradyi, Ilyocypris decipiens, Cypris mandelstami, Zonocypris membranae quadricella, Potamocypris fulva, Cyprideis crotonensis, Cyprideis rectangularis and two new species: Hemicypris lomastroi sp. nov. and Paralimnocythere turgida sp. nov. In addition to widespread European species, the ostracod assemblages contain some rare species that were previously known from the Pliocene Paludinian Beds of Serbia. A cluster analysis applied to the ostracod frequency matrix has lead to the identification of four separate assemblages that can be attributed to several ecological niches, including emerged hydrosols, ephemeral coastal pools and a littoral lacustrine margin, which suggest a complex coastal environment.

A Late Miocene – Early Pliocene Paratethyan Type Ostracod Fauna From the Denizli Basin (Sw Anatolia) and Its Palaeogeographic Implications

“…Inside the Paratethyan domain it has been obtained from a variety of basins, e.g., the upper Maeotian (Bădislava and Toplog sections) and Dacian (Slănicul de Buzău) of the Dacian Basin (Romania) (Floroiu et al, 2016;Jorissen et al, 2018), the upper Productive Series (Surakhany Fm., Kimmerian age) and the Akchagylian-Apsheronian of the South Caspian Basin of Azerbaijan (Van Baak et al, 2013;Lazarev et al, 2019) and the middle Pannonian of the Gelibolu Peninsula (NW Turkey) (Tunoğlu and Ünal, 2001). Further is appears during the Piacenzian-Gelasian in the Tiberino Basin in the Central Apennines of Italy (Spadi et al, 2019) and the Quarternary deposits of the Gorgan plain in North Iran (Yassini, 1987). According to Agalarova et al (1961) and Mandelstam et al (1962), it also occurs in the Pliocene and post-Pliocene deposits of Azerbaidjan, Turkmenistan SSR and Caucasus region.…”

An updated checklist of Recent ostracods (Crustacea: Ostracoda) from inland waters of Sicily and adjacent small islands with notes on their distribution and ecology

“…C from Israel (Rossetti & Martens 1999). Fossil representatives of this genus were reported for Italy from the Neogene (e.g., Ligios et al 2009;Spadi et al 2019).…”
