(Type No. 5). Another one, <i>Macrosporites</i> cf.<i> brasserti</i> (Stach & Zerndt) is a derived carboniferous form. Two assemblage zones are defined, namely the <i>T. pinguis</i> Assemblage Zone(below, Rhaetic) and the <i>N. hopliticus</i> Assemblage Zone (above, Lower Lias).</p><p>10 species of ostracods from the Lias section are described, of which two are new: <i>Procyrheridea mediorericulata</i> n. sp. and <i>Stenestroemia</i> ? <i>roedbyensis</i> n. sp., and five have open nomenclature. The ostracods from the Rhaetic are registered but not described. The <i>O. aspinata</i> Assemblage Zone (Lower Lias) is defined.</p><p>The Rhacto-Liassic section is divided chronostratigraphically in Middle Rhaetic, Upper Rhaetic, Lower Hettangian, Upper Hettangian, and ? Lower Sinemurian.</p> ER -
