鄂西荆门-当阳盆地九里岗组几种丁菲羊齿植物

本文报道了鄂西荆门-当阳盆地晚三叠世九里岗组几种丁菲羊齿(Thinnfeldia)植物,即雅致丁菲羊齿[(新种)Thinnfeldia elegans(sp.nov.)]、南漳丁菲羊齿[(新种)Thinnfeldiananzhangensis(sp.nov.)]、远安丁菲羊齿[(新种)Thinnfeldia yuaanancnsis(sp.nov.)],并对九里岗组植物群的性质进行了扼要的讨论,初步认为该植物群具有我国南、北晚三叠世两个植物群的过渡性质。     

鄂西晚三叠世几种种子蕨及其演变趋势

本文报道了采自鄂西晚三叠世地层中的五种种子蕨植物,它们分别隶属于副镰羽叶(Paradrepanozamites)、丁菲羊齿(Thinnfeldia)和篦羽羊齿(Ctenozamites)三个属。由于这些植物的小羽片或羽片基部上边均明显收缩,基部下边均显著下延等,认为它们在系统发生上可能有密切的亲缘关系,并提出它们的形态结构可能朝两个方向发展:一是输导组织不断发达——叶脉从亚放射状,无中脉→有中脉但不发达→中脉发达→变成末级羽轴;二是小羽片或羽片由全缘→局部分裂→大部分裂→羽状全裂。同时,根据奇特篦羽羊齿(新种)[Ctenoza-mites difformis(sp.nov.)]同一植株上的叶呈现四种不同的形态和脉序,初步推测上述三属的演变趋势是:由 Paradrepanozamites→Thinnfeldia→Ctenozamites。
