“…This includes descriptions from Venezuela (e.g. Berry & Stein, 2000;Berry, 2000;Berry & Edwards, 1996;Edwards & Benedetto, 1985), Colombia , Brazil (Gerrienne, 1999;Gerrienne et al 2001) and Bolivia (Edwards et al 2001a). In Argentina, the presence of Devonian plants has previously been recorded by Halle (1936), Frenguelli (1951Frenguelli ( , 1952, Menendez (1967), Archangelsky (1983), Morel et al (1993), Gutierrez (1996), Gutierrez & Archangelsky (1997) and Edwards et al (2001b), although frequently age and accurate determination of the fossils is debated.…”

-Fossil plants are described from the upper part of the Devonian Lolén Formation, Sierra de la Ventana, Buenos Aires Province, Argentina, in the area of Estancia Las Acacias. The sequence is composed mainly of dark grey shales, and fossils were found in a single horizon where thin interlayered beds of fine reddish-brown micaceous sandstones appear where the environment of marine deposition became more shallow. The age of the Lolén Formation is presently established on the basis of brachiopods, these being characteristic elements of the Malvinokaffric realm from the Gondwana Lower Devonian (Emsian). The fossil plants are remarkably preserved given that they are in rocks that have undergone intense deformation. The plants are identified as Haplostigma sp. and Haskinsia cf. H. colophylla, and suggest a Middle Devonian age (Givetian) for the fossil-bearing levels. Haskinsia, identified on the basis of leaf morphology, is the first well-delimited Middle Devonian lycopsid genus described from Argentina, and the record from the most southerly palaeolatitude. During the Middle Devonian, Haskinsia was distributed in tropical, warm temperate and high southern latitude, ?cool temperate zones.

“…11 km west of the PISA locality, is probably coeval of the PISA locality. However, no spores have been found at this locality (Gerrienne et al, 2001). Loboziak et al (1995), based on spores in the uppermost Furnas Formation (ca.…”

“…The Furnas Formation shows a general regressive tendency upwards. The early land plant beds are here considered as a late Lochkovian datum plane (Si Phylozone in the MN Oppel Zone; Gerrienne et al, 2001;Rubinstein et al, 2005Rubinstein et al, , 2008. A dense sampling of core 9-PPG-6-PR from the base of the "transitional beds" (76.5 to 80.7 m) below typical Ponta Grossa Formation (from 76.5 m upwards; Figures 3, 5) revealed that these beds are probably late Pragianearly Emsian.…”

“…Based on spores, Dino & Rodrigues (1995) dated early land plants in the upper Furnas Formation (included in the transitional beds by Petri, 1948) at PISA (Figure 2) to be of Pragian age, and the overlying Ponta Grossa Formation to be of Emsian age. Spores identified by Steemans from PISA during the 1990s was partially published by Gerrienne et al (2001). The same samples, complemented by new ones, were used to review the age previously assigned, which was considered as early Lochkovian (Gerrienne et al, 2001).…”

Rev. bras. paleontol. 13 (2) ABSTRACT -The Furnas/Ponta Grossa Formation contact was until recently considered gradational or abrupt and of a Lochkovian to Pragian age in the Apucarana Sub-basin (Paraná Basin, south Brazil). Based on sedimentology and palynomorph evidence a hiatus has been revealed between the Furnas Formation and the overlying Ponta Grossa Formation. The boundary between the topmost Furnas sandstones and the lowermost Ponta Grossa fine-grained sandstones constitutes a transgressive ravinement surface generated during a latest Pragian -early Emsian transgression. The hiatus corresponds to a maximum of ca. 4 Ma. A similar gap is also present in the Alto Garças Sub-basin.
