“…Merlotti and Kurzawe (2011) attributed the stratigraphic position of the solenoid taxon Ductosolenoxylon and the nonsolenoid taxa Paulistoxylon, Abietopitys, Septomedulloxylon, Corticoxylon and Vertebraria to the Serra Alta Formation, which overlies the Irati Formation in the southern part of the basin. However, new results obtained by Guerra-Sommer during field expedition revealed that these woods were included in the topmost horizon of the Irati Formation (unpublished data).…”

“…The genera of Solenopitys and Atlanticoxylon are restricted to the Permian, with Solenopitys being more widely distributed in the southern part of Gondwanaland, from the Paraná Basin in the south of Brazil (Irati Formation; Mussa 1986) to the Falkland Islands (Mussa 1986), South Africa and Antarctica (Merlotti and Kurzawe 2011). Atlanticoxylon, on the other hand, was limited to the Paraná Basin (Irati Formation, Mussa 1986; Merlotti and Kurzawe 2011) and India (Guerra-Sommer et al 2014).…”

This research described fossil woods with preserved pith and primary xylem from strata of the Irati Formation (Artinskian) of the Paraná Basin (southeastern Brazil). The three specimens studied are all related to the Coniferales and include the following taxa: Solenopitys paulistana Kräusel, Atlanticoxylon ibiratinum n. sp. and Abietopitys sp. Kräusel. Solenopitys paulistana represents a species with a solid, heterocellular pith with a peripheral secretory canal system. Atlanticoxylon ibiratinum n. sp. has a lacunose, heterocelular pith with Bnests^of sclereids, with a central secretory canal and a peripheral system of canals. Abietopitys sp. has a solid, lobed, homocelular pith associated with a secondary xylem containing cross-fields with non-contiguous pits (abietoid vascular rays). Xeromorphic features observed in these specimens, such as a pith with groups of sclereids and false growth rings, may be related to the depositional environment of the Irati Formation. The specific factor triggering the xeromorphy has not yet been determined, but the present study corroborates clearly the sedimentary evidence of dry conditions during the deposition of the Irati Formation, as seen in the 30-m-thick carbonate layer extending through four South American countries.

“…The Jaccard Coefficient is also a very powerful tool for analysing data regarding presence-absence with no importance on abundance (Legendre and Legendre, 1998;Hammer et al, 2001). Thus, cluster and Jaccard Coefficient analyses were undertaken to compare some Moscovian to Cisuralian anatomically preserved floras presented by Hilton and Cleal (2007), augmented by European floras from the Perdasdefogu Basin, Sardinia/Italy (Galtier et al, 2011), Grand-Croix, Saint-Étienne Basin, and Autun/France (Galtier, 2008), Leukersdorf Formation of the Petrified Forest of Chemnitz/Germany , Semily and Vrchlabí formations from Krkonoše Piedmont Basin/Nova Paka/Czech Republic (data provided by Dr. Vaclav Mencl, 2015), and Irati Formation from the Paraná Basin, southern Brazil (Mussa, 1978a(Mussa, ,b, 1982(Mussa, , 1986Mussa et al, 1980;Merlotti, 2009;Merlotti and Kurzawe, 2011). Hilton and Cleal (2007) presented an analysis of 19 Euramerican and Cathaysian floras, ranging from early Bashkirian up to Asselian-Sakmarian age.…”

Continuing palaeofloristic studies in the Northern Tocantins Fossil Forest, we describe two new calamitalean species from the Permian of the Parnaíba Basin (central-north Brazil). The fossils comprise axes of various sizes, preserved anatomically as siliceous petrifactions, and found in highly mature sandy fluvial deposits of the Motuca Formation. Based on anatomical and morphological characteristics, Arthropitys tocantinensis sp. nov. and Arthropitys barthelii sp. nov. are described. They share a small central pith cavity (extremely reduced in the latter), scalariform tracheid pitting, and prominent pitting of the ray parenchyma. However, they differ markedly in their branching system: the former having 3-12 branches per node either with or lacking secondary growth, the latter showing 2-17 branches without any secondary growth. However, in A. tocantinensis sp. nov., the presence of large woody branches supports a more complex architecture with at least three successive orders of branches. The extensive secondary tissue in both species is homogeneous; clear segmentation is only visible in the proximal wood of A. tocantinensis sp. nov., but completely absent in A. barthelii sp. nov. The growth architecture of these upright growing, self-supporting trunks are reconstructed based on sizable transverse and longitudinal preparations. Our results confirm that thick woody calamitaleans were elements of disturbed riparian vegetation and much more diverse in terms of anatomy and branching patterns than previously thought. They were well adapted to seasonally dry conditions and formed major plant constituents of Permian low-latitude Southern Hemisphere communities. Additionally, we report the first evidence of colonisation on arborescent calamitaleans by herbaceous sphenophyte axes from the Permian. One of the Arthropitys stems hosts at least 30 Sphenophyllum shoots of various ontogenetic stages, growing inside the destroyed pith, which was previously excavated by arthropod boring. Based on the distribution of key genera within late Paleozoic floras of Euramerica, Gondwana and Cathaysia floral realms cluster analysis and Jaccard Coefficient highlight the distribution of a "Mid-North Brazilian" phytogeographic Region during the early Permian.
