鄂西地区泥盆纪地层分布广泛,剖面完好,化石丰富,是我国晚泥盆世早期黄家磴阶建阶地区。 泥盆纪叶肢介化石在国外有少数报道,在我国除晚泥盆世晚期有报导外,晚泥盆世早期至今没有发现和报导。因此,鄂西地区上泥盆统下部黄家磴组叶肢介化石的首次发现,不仅对于研究叶肢介的演化。地层时代和地理分布有重要意义,而且对丰富黄家磴组生物内容也是重要的。 黄家磴组化石孢子十分丰富,计30余属,70余种、由于篇幅所限,仅部分予以报道,特别有意义的是在叶肢介化石同一标本所发现的孢子,对于沉积环境、动植物群之间的关系等研究提供了线索,并且增添了新内容。
The Devonian strata in western Hubei are widely distributed, well-profiled and rich in fossils, and are the areas of the Huangjiagian order built in the early period of Late Devonian in China. There are a few reports of Devonian foliar fossils in foreign countries. In our country, except in the late Devonian period, no reports and reports have been made since early Late Devonian. Therefore, the first discovery of foliar fossils in the Lower Devonian Formation in Upper Devonian in western Hubei Province is not only of great interest in studying the evolution of leaf-limbs. The age and geographical distribution of the strata are of great importance and are also important for enriching the biological content of the Huangjiatuan Formation. The fossil spores of the Huangjiadao Formation are very rich, accounting for more than 30 genus and more than 70 species. Due to limited space, only some of them are reported. Of particular interest is the spores found in the same specimen of phylloliths. For the sedimentary environment, The relationship between flora and other research provides a clue, and added new content.
