“…Valves with ''cup in cup'' structure are present in this ostracod species. This arrangement of ostracod valves has been reported on several occasions from a number of fossil sequences (Wakefield & Athersuch, 1990;Wakefield, 1995;Boomer et al, 2001;Carignano & Ballent, 2009). Fontana & Ballent (2005) documented this phenomenon in a recent cypridid from southern Buenos Aires Province, Argentina.…”

Early Mesozoic Argentinian darwinuloids, now re-assigned to the genus Penthesilenula (incae group), are described and illustrated. These records seem to constitute the oldest known for the genus. The close similarities between the studied species and those described from eastern Asia enlarge the geographical distribution of Penthesilenula (incae group), which, although restricted to the southern Hemisphere in Recent and Holocene times, may have had a wider distribution in the past. Additional information on the paleoecology, plus a preliminary account on the distribution of darwinulid species from Argentina are also offered. One new species is described: Penthesilenula loana sp. nov.

Amphicypris argentinensis sp. nov., is described and illustrated from Laguna Caliba, an ephemeral fresh water lake from the southern coast of Buenos Aires Province, Argentina. Specimens were raised from dried sediment recovered from a bank of ostracod shells found at the edges of the lake. Deposition of progressively smaller ostracod valves stacked one into another (cup-in-cup structure) is documented. The geographical distribution and ecology of the genus is briefly discussed.

“…The westernmost sector (Monte Baldo and Adige River area) is mainly characterised by marginal oolitic shoals. The typical facies of the Rotzo Formation are ooidal, peloidal, bioclastic and intraclastic limestones with marly and clayey horizons rich in plant remains and thin coal levels (Broglio Loriga and Neri 1976;Boomer et al 2001;Roghi and Romano 2008;Posenato and Masetti 2012). Macrofossils are common and include molluscs (large and small bivalves such as Lithiotis s.l.…”

“…Thaumatoporella parvovesiculifera) and ostracods (e.g. Phraterfabanella tridentinensis), although foraminifera are locally rare (Bosellini and Broglio Loriga 1971;Fugagnoli and Loriga Broglio 1998;Boomer et al 2001). The lower part of the Rotzo Formation yielded also a rich palynoflora including Ischyosporites variegatus (Couper) Schulz, 1967, Leptolepidites major Couper, 1953, Matonisporites crassiangulatus Levet-Carette, 1964, and Trilites lygodioides Mai, 1967, that was previously attributed to the Toarcian (Schulz 1967), but is now known to extend to the Sinemurian-Pliensbachian (Avanzini et al 2006).…”

The Rotzo Formation is famous for its Lower Jurassic terrestrial flora and marine (invertebrate) and terrestrial (dinosaur footprint) fauna. However, lycophyte macrofossils were never described from this time period in Italy, although palynological analyses yielded abundant lycophyte spores. Dispersed megaspores, in association with charcoal and amber drops, were recently collected from several horizons and outcrops of the Monte Lessini area. Sedimentological and palaeontological data reconstruct the palaeoenvironment as a paralic swamp under a warm and humid (monsoonal) climate. This is the first record of Jurassic megaspores from Italy, increasing our understanding of Jurassic lycophyte diversity, since at least five microspore and five megaspore genera with selaginellalean botanical affinities can be distinguished. Moreover, this underlines how well these brackish environments were adapted for the preservation of fossil plant remains (including amber).
