| 摘 要： | 近来于黑龙江七台河勃利盆地城子河组中发现了一种大型叶状体苔类化石.借鉴蕨类化石羽状复叶结构的描述方法,提出了一套新的术语并用来准确描述这种苔类化石.在体式显微镜和扫描电镜下详细研究了这种二歧式分叉的大型叶状体苔类的宏观和微观特征,并与同时代或同分布区的其他苔类化石分析对比后,确定为古似地钱属的Marchantiolites blairmorensis.这种苔类化石在黑龙江的首次发现表明早白垩世M.blairmorensis在中国的分布区已北延至黑龙江东部,亦佐证了城子河组的地质时代为早白垩世,并推论勃利盆地当时的古生态环境为溪流发育、植被繁盛的湖泊沼泽环境.

| Abstract: | Recently,a kind of mega thallus fossil was found from the lower cretaceous Chengzihe formation of Jixi group in the Boli basin of Qitaihe city,Heilongjiang province.By using the approach and terminology describing the pinnately compound leaf of fossil ferns,a new set ofterminology was established to accurately describe the dichotomous mega thalloid liverwort in detail.The fossils were observed with a stereo microscope and a scanning electron microscope,and compared with some other fossil liverworts from the... |
