Pseudolarix
''Pseudolarix'' is a genus of coniferous trees in the pine family Pinaceae containing three species, the extant '' Pseudolarix amabilis'' and the extinct species '' Pseudolarix japonica'' and '' Pseudolarix wehrii''. ''Pseudolarix'' species are commonly known as golden larch, but are not true larches (''Larix'') being more closely related to '' Keteleeria'', ''Abies'' and ''Cedrus''. ''P. amabilis'' is native to eastern China, occurring in small areas in the mountains of southern Anhui, Zhejiang, Fujian, Jiangxi, Hunan, Hubei and eastern Sichuan, at altitudes of . ''P. wehrii'' is described from fossils dating to the Early Eocene (Ypresian), of Western North America where it is found in the Eocene Okanagan Highlands Allenby and Klondike Mountain Formations. The youngest known occurrence is of mummified fossils found in the Late Eocene Buchanan Lake Formation on Axel Heiberg Island. ''P. japonica'' is known from Middle Miocene to Pliocene sediments in Japan and Miocene deposits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allenby Formation
The Allenby formation is a sedimentary rock formation in British Columbia which was deposited during the Ypresian stage of the Early Eocene. It consists of conglomerates, sandstones with interbedded shales and coal. The shales contain an abundance of insect, fish and plant fossils known from 1877 and onward, while the Princeton Chert was first indented in the 1950's and is known from anatomically preserved plants. There are several notable fossil producing localities in the Princeton & Tulameen basins. Historical collection sites included Nine Mile Creek, Vermilian Bluffs, and Whipsaw Creek, while modern sites include One Mile Creek, Pleasant Valley, Thomas Ranch, and the Princeton Chert. Extent and correlation The Allenby is estimated to have an overall extent of approximately , though actual outcroppings of the formation make up less than 1% of the formation, while other exploratory contact is via boreholes and mines. The half-graben which contains the formation is separa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Ear ...

Fujian
Fujian (; alternately romanized as Fukien or Hokkien) is a province on the southeastern coast of China. Fujian is bordered by Zhejiang to the north, Jiangxi to the west, Guangdong to the south, and the Taiwan Strait to the east. Its capital is Fuzhou, while its largest city by population is Quanzhou, both located near the coast of the Taiwan Strait in the east of the province. While its population is predominantly of Chinese ethnicity, it is one of the most culturally and linguistically diverse provinces in China. The dialects of the language group Min Chinese were most commonly spoken within the province, including the Fuzhou dialect of northeastern Fujian and various Hokkien dialects of southeastern Fujian. Hakka Chinese is also spoken, by the Hakka people in Fujian. Min dialects, Hakka and Mandarin Chinese are mutually unintelligible. Due to emigration, a sizable amount of the ethnic Chinese populations of Taiwan, Singapore, Malaysia, Indonesia, and the Philippin ...

Axel Heiberg Island
Axel Heiberg Island ( iu, ᐅᒥᖕᒪᑦ ᓄᓈᑦ, ) is an uninhabited island in the Qikiqtaaluk Region, Nunavut, Canada. Located in the Arctic Ocean, it is the 32nd largest island in the world and Canada's seventh largest island. According to Statistics Canada, it has an area of . It is named after Axel Heiberg. One of the larger members of the Arctic Archipelago, it is also a member of the Sverdrup Islands and Queen Elizabeth Islands. It is known for its unusual fossil forests, which date from the Eocene period. Owing to the lack of mineralization in many of the forest specimens, the traditional characterization of "fossilisation" fails for these forests and "mummification" may be a clearer description. The fossil records provide strong evidence that the Axel Heiberg forest was a high-latitude wetland forest. History Axel Heiberg Island has been inhabited in the past by the Inuit, but was uninhabited by the time it was named by Otto Sverdrup, who explored it in 190 ...
