This is the website of the World Wide Web Virtual Library: Paleoclimatology and Paleoceanography.

这是全球网虚拟图书馆：古气候学与古海洋学的网站。

The database is created by NOAA Paleoclimatology Program and World Data Center for Paleoclimatology, and one part of the databases.

该数据库由美国国家海洋和大气局古气候学计划组及世界数据中心古气候学分中心创建，是其中的数据库之一。

In the past few years, these problems have drawn extensive studies and intensive controversies in the fields of paleo-geology, paleontology, and paleoclimatology.

围绕这些问题，古地质、古生物和古气候学界在最近几年展开了广泛的研究和激烈争论。

The generic distributions in both modern and fossil times were outlined, and their distribution center, place and time of origin and the way of dispersal were discussed. An attempt was made to discuss early differentiation, geographical radiation and morphological evolution of the family on the background of paleogeography and paleoclimatology, tracing back as far as the Late Cretaceous and Early Tertiary.

作者试图回到遥远的晚白垩纪和旱第三纪，从描绘桦木科植物起源和早期分化的古地理和古气候背景入手，分析了在这种背景下桦木科植物所发生的空间辐射以及植物体本身所产生的形态进化，以求得对桦木科植物起源、散布和分化作出比较合理的解释。

It is possible that the alternation of black shale and CORBs occurs in certain units. By correlating the globally distributed CORBs from Barremian to Maastrichitian, this paper discussed the temporal and spatial evolution of CORBs and its implications for paleoceanography and paleoclimatology.

基于此，本人通过对贝雷姆阶到马斯特里赫特阶全球大洋红层的研究，对大洋红层的时空演化进行了探讨，并讨论了其古海洋、古气候意义。

Most of the published suid fossils are reviewed and suggested a new systematic position now. The relationship of Chinese fossil suoids with that from Indian subcontinent and Europe are carefully discussed, the new understanding of Paleogeography and paleoecology during the Neogene of China are proposed.

通过对各时期我国发现的猪形类化石的重新研究，厘定了我国所有重要猪形类化石的分类，并对中国猪形类与印巴大陆、欧洲大陆猪形类的关系进行了详细的探讨，对古地理、古气候提出了新的见解。

Author suggest that established system of Eco-toxicology in Paleoecology, to prevent toxicant into body for us, to against foreign living intrude , to study Eco-toxicology and that established principles of law to protect from ecological safety, living things safety and food safety for our country and people.

作者就研究恐龙灭绝对我们今天的意义提出了一些新的见解，认为"中毒说"丰富了古生态学，为建立古生态毒理系统提供了依据；启示我们谨防生活中的毒物，严防境外有毒有害生物入侵，加强生态毒理学研究，进一步健全法律保障体系，确保生态安全，生物安全和食品安全。
