美國石化森林國家公園(petrified forest nationalpark)，地處亞利桑纳州北部,每年吸引全球60万人前去拜該，当地法律却规定不准任何人私带一塊石頭離開，如若違反，按美國联邦法和亞利桑纳州法双重法律論處。景區內有由红砂岩嚴重風化形成的彩色沙漠景觀(Painted Desert--彩繪沙漠)，有数以千計化石成宛如珍珠瑪瑙的硅化木樹幹，更有色彩變化多端的藍色臺地山丘(Blue Mesa). j2 \- \) \# w H! V

The Petrified Forest is known for its fossils, especially fallen trees that lived in the Late Triassic, about 225 million years ago. The sediments containing the fossil logs are part of the widespread and colorful Chinle Formation, from which the Painted Desert gets its name. Beginning about 60 million years ago, the Colorado Plateau, of which the park is part, was pushed upward by tectonic forces and exposed to increased erosion. All of the park's rock layers above the Chinle, except geologically recent ones found in parts of the park, have been removed by wind and water. In addition to petrified logs, fossils found in the park have included Late Triassic ferns, cycads, ginkgoes, and many other plants as well as fauna including giant reptiles called phytosaurs, large amphibians, and early dinosaurs. Paleontologists have been unearthing and studying the park's fossils since the early 20th century.作者: 繪里 時間: 2013-4-21 01:46 AM
