<abstract xmlns="http://www.w3.org/1999/xhtml">Typification of Sydneia manleyi Pšenička et al. 2003 is based
 entirely on fertile foliage. Of late, attached sterile-fertile segments have
 been found which are illustrated and described, together with cutic-ular
 preparations. A new subfamily, Sydneideae subfam. nov. is erected for the
 monotypytic species. The synangial chemistry is compared with marattialean
 synangia/sporangia from the Czech Republic and from Canada.</abstract>

Sterile Foliage of Fertile <italic>Sydneia Manleyi</italic> and
 Synangial Chemistry (Eusporangiate Fern, Late Asturian, Canada): A New Subfamily
 Sydneideae

<abstract xmlns="http://www.w3.org/1999/xhtml">The late Paleozoic deposits in several basins in the Czech Republic are well
 known for their abundance of silicified stems. Despite the fact they have been
 known since 19th century, there are few modern works of this material. The stems
 have been known to occur at several stratigraphic levels. During the course of
 recent field work such material has been found at additional levels. Most of
 them belong to the genus <italic>Agathoxylon</italic>, divided here into two
 types: cordaitalean plants and conifers. Based on previous data from Intra
 Sudetic and Pilsen Basins, and new material from Krkonoše Piedmont and
 Kladno-Rakovník Basins, this work compiles and compares the occurrence,
 anatomical features and taxonomy of silicified Agathoxylon-type of stems through
 four studied areas. The various cordaitalean - conifer ratio among all basins
 reflect different palaeoenvironment in each of them.</abstract>

Summary of Occurrence and Taxonomy of Silicified
 <italic>Agathoxylon</italic>-Type of Wood in Late Paleozoic Basins of the
 Czech Republic

<abstract xmlns="http://www.w3.org/1999/xhtml">The first record of a chiton (Polyplacophora) from the Bohemian Cretaceous Basin
 (Late Creta-ceous) is described herein. It comes from the working quarry of
 Plaňany, located near the town Kolín. Excavated deposits are of
 the late Cenomanian - early Turonian. The poorly preserved specimen consists of
 a tail valve remain and two intermediate valves, it is associated herein only
 with order level - i.e. Le-pidopleurida Thiele, 1910. The state of its
 preservation shows signs of corrosion of dorsal part caused probably by biologic
 digestion (in stomach) and/or, more probably, by long exposure at the sea
 bottom. Stratigraphically, the layer yielding chiton shell is referred to be the
 late Cenomanian in age. The chiton living conditions are interpreted as very
 shallow water environment (not exceeding 20m) with irregular rocky basement
 possessing numerous caves and crevices.</abstract>

First Record of a Fos Sil Chiton (Polyplacophora) from the Bohemian

<abstract xmlns="http://www.w3.org/1999/xhtml">Twenty nine fossiliferous localities of the Třenice Formation are
 described. As we were able to find they represent all fossil sites ever been
 described from that basal unit of the Prague Basin. Based on critical evaluation
 of the previously published data fossil taxa from all relevant publications are
 summa-rized and historic names used for the localities are mentioned. Updated
 lists of fauna are compiled for each locality as well as for the formation as a
 whole.</abstract>
