First anatomically characterized wood from the Tertiary of Moravia: Spiroplatanoxylon from the area of Austerlitz (Southern Moravia, Czech Republic)

Abstract

TOVÁRKOVÁ, I., GRYC, V. SAKALA, J.: First anatomically characterized wood from the Tertiary of Moravia:Spiroplatanoxylon from the area of Austerlitz (Southern Moravia, Czech Republic). Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 6, pp. 367-372 A new silicifi ed angiosperm wood from the alluvial sediments in Vážany nad Litavou (SW of Slavkov/ Austerlitz near Brno, Vyškov district) is described. The wood is diff use-porous with indistinct growth ring boundaries. Vessels are exclusively solitary with helical thickenings and scalariform perforation plates. Rays are very high and up to 18 cells wide, homocellular to slightly heterocellular. Crystals are present in axial parenchyma mostly in chambered cells, rarely in idioblasts. The fossil is attributed to Spiroplatanoxylon mueller-stollii Süss. Other species of Spiroplatanoxylon are also discussed. Wood anatomical descriptions from the eastern part of the Czech Republic published so far deal either with the Silesian Tertiary or describe only partially lignifi ed probably Quaternary material; therefore the present paper can be considered as the fi rst detailed anatomical description of the Tertiary wood from Moravia.silicifi ed angiosperm wood, Spiroplatanoxylon, Tertiary, Moravia, Czech RepublicThe Tertiary silicifi ed wood is quite abundant in Moravia and it was the subject of several publications but without any mention about its anatomical

Palaeoxylotomical Study of a New Collection From Zarand Miocene Petrified Forest, South Apuseni Mts.

“…Its secondary xylem has moderately small vessels in radial small groups, having scalariform and simple perforations, intervascular bordered pits elongate to scalariform parenchyma apotracheal, two-sized rays with typical platanoid dilation at the ring boundary (Greguss, 1959;Watson & Dallwitz, 1992) As it is known, there are three still valid fossil genera of platanaceous woods: Plataninium, Platanoxylon and Spiroplatanoxylon. Extended discussions concerning the validity of these genera and of their associated species are already published (Süss, 2007;Sakala et al, 2010;Gryc & Sakala, 2010;Továrková et al, 2011;Koutecky & Sakala, 2015;Iamandei et al, 2020, in this Journal).…”

Fossil Woods From Bozovici (Sw Romania)

“…nova, and two new species of Spiroplatanoxylon were described: Süss, 2007, which has bigger vessels, mostly solitary and less frequent per square mm, very abundant tyloses, broad multiseriate rays and crystals in the axial parenchyma present as chambered cells or, rarely, as idioblasts. -S. mueller-stollii Süss, 2007, quite similar, with mostly solitary vessels, less frequent per square mm, very abundant tyloses, generally thinner rays, which can even be aggregated and also broad multiseriate rays and crystals in the axial parenchyma present as chambered cells or, rarely, as idioblasts; the same species was identified by Továrková et al (2011) from Brno area, Czech Rep. Also, several species of Icacinoxylon, Platanoxylon and Plataninium are reidentified and placed into the genus Spiroplatanoxylon. It is very of note that even Page (1968) also emended once the genus Plataninium, to comprise broader-rayed structures, including members of the Icacinaceae (equivalents of Citronella, Ottoschultzia).…”

“…Generally, their presence is important in delimiting the fossil genus Spiroplatanoxylon süss, 2007 (e.g. Sakala et al 2010, Továrková et al 2011. We regrouped here all "Icacinoxylon sp.…”
