Tte also suggest a possible comparison with the Ediacara trilobozoan fossils-Albumares and Anfesta from the shores of the White Sea in Russia. The re-cent discovery of a few skewed E. octobrachiata and walnut-shaped fossils with several carbonaceous meridian bands believed to represent lateral compressions of the same organism strongly suggests that this octoradial fossil is a ctenophoran.

新发现的倾斜保存的八臂仙母虫化石和碳质条带呈子午线状排列的核桃状化石,可能是该类化石归属栉水母类的有力证据,这一发现推测可将栉水母类的最早化石记录从"澄江生物群"的早寒武世推前大约3千万年。

From the composite section, it can be found that some fossils'range zones are too short. Maybe it is caused by the fossils not preserved properly or the samples not collected comprehensively. Most fossils'first occurrence data are later than the ages which are defined by the MIDK4 composite section. It is probably caused by the Foraminifer zones in Tethyan- Himalaya which are not isochronous with other areas. It can also be recognized that there are two major extinction and revival events at the boundary of Cenomanian/Turonian and the boundary of Coniacian/ Santonian. They are coincident with the two Ocean Anoxic Events and can be considered as the typical response by creatures.

在复合剖面上可以发现:一些化石的延限非常短,这可能是由于化石保存不完整或者样品采集不全造成的;大部分化石的首现面年龄值都要晚于MIDK4数据库复合剖面给出的年龄值,这可能是由于特提斯喜马拉雅带与全球其他地区的有孔虫化石带不等时造成的;同时,可以在复合剖面上识别出在Cenomanian/Turonian界线附近和Coniacian/Santonian界线附近存在两次大规模的生物灭绝和复苏事件,这正好与两次大洋缺氧事件发生的时间一致,可以作为缺氧事件的生物标志。

First,we have discovered stone artefacts in caves, which have similar features to that were broadly scattered in laterite terraces in Bose basin(0.8 Ma B.P),next study on deposits and fauna will be hopefully contributed to document paleoenvironmental background of early human;Second,early human fossils,Gigantopithecus and mammalian fossils unearthed in Mohui cave provide new evidence of early human origin; Third,after our scientific excavation in Fengshudao site in Bose basin, we have found five pieces of bi-face LCT with 10 tektites and nearly 100 stone artefacts form original laterite deposit.This important discovery is very answerable to international question about stratigraphic suspect of LCT; Fourth, abounding mammallian fossils with human fossils and remains from early Pleistocene to Holocene have been uncovered after systematically excavation in marginal cave of Bose basin.These discoveries are significant to the study on human evolution and establishment of sequence of Quarternary biological-stratigraphic in southern China.

首先,我们在百色盆地边缘洞穴堆积物中,发现与百色盆地内网纹红土阶地(0.8 Ma )类型相似的石制品,通过对堆积物及其包含动物群的研究有望对解决早期人类生存环境背景作出贡献;其次,在么会洞发现了早更新世早期大约1.8 Ma 的人类化石、巨猿化石和丰富的哺乳动物化石,为解决早期人类起源提供了新的证据;再次,在百色盆地枫树岛旧石器时代遗址,通过科学发掘,从原生地层中发现五件与玻璃陨石共生的手斧,以及近百件其它类型的石制品,解决了目前国际学术界普遍关注的百色手斧的层位问题,为进一步确定百色旧石器的时代奠定了基础;另外,通过对百色盆地边缘洞穴的系统发掘,发现了自早更新世早期至全新世以来不同时代的大量哺乳动物化石,同时还发现中更新世晚期--晚更新世早期和全新世的人类化石和石制品,对研究人类演化、建立华南第四纪生物地层序列具有重要的科学意义。

A highly diversified macrofossil assemblage was discovered from the Jiucheng Member of the uppermost Ediacaran of Jinning and Jiangchuan areas in eastern Yunnan. In addition to abundant Vendotaenia and Tyrasotaenia, large multicellular benthos such as Tawuia-like and Longfengshaniaceae fossils with diverse holdfast structures, have a distinct dominance, while there are still some other macrofossils with peculiar configurations as well as indistinct relatives. There is an obvious distinction between this assemblage and the macrofossil assemblages from the Doushantuo Formation and the Shibantan Member of the Dengying Formation in South China.

The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.

栲属在地质历史上有着比现在广泛的分布,最早、最可靠的栲属化石记录发现于始新世地层,栗亚科化石在古新世就有发现,化石记录表明栲属起源的时间不晚于古新世,所有的壳斗科及栲属的化石都发现于北半球,现代分布也主要在北半球,壳斗科及栲属起源于北半球可以确认,由于化石证据与现代植物学的研究结果有较大差异以及关键地区化石证据的不足,具体的起源地尚不能肯定。

The specimen was preliminary coated with carbon of 10-20 nm in thickness, then sputtered with gold of various thickness according to its shape and surface texture: a gold film of 60-80 nm in thickness for bell-jar or tower-type radiolarites, 80-140 nm for globiferous radiolarites with spines and 140-200 nm for globiferous radiolarites.

Supposes in 4,600,000,000 years perpetual flow in this, actually has had any, is already unable to recount; Only then from ancient stratum, discovery life process surviving vestige, but also might the testimony a wee bit remote past, such as: Early zoology and botany fossils and so on trilobita fossil, fish fossil, ferns, as well as after dinosaur fossil, fossils of bird, primitive time animal and human ancestor's fossil, but also had in the ancient times human history civilization corpse body with non-body vestige and so on, these vestiges nearly surmounted the entire Earth's life evolution history.

在这假定46亿年的长河中,究竟发生了什么,早已无法述说;只有从古老的地层中,发现的生命过程残存的遗迹,还可以见证一丁点儿的遥远过去,诸如:三叶虫化石、鱼化石、蕨类等早期动植物化石,以及之后的恐龙化石、鸟化石、原始时代动物及人类祖先的化石,还有古代人类历史文明中的尸体躯壳与非躯壳遗迹等等,这些遗迹几乎跨越了整个地球的生命演变史。
