The Świętokrzyskie Mountains, or Holy Cross Mountains (Polish: ), are a mountain range in central Poland, in the vicinity of the city of Kielce. ''The Świętokrzyskie Mountains'' are some of the oldest mountains in Europe, and the highest between ''The Sudet Mountains'' and the ''Ural Mountains''.〔http://voyageforum.pl/threads/1312-Najstarsze-g%C3%B3ry-w-Europie〕 The mountain range comprises several lesser ranges, the highest of which is ''Łysogóry'' (the "Bald Mountains"). The two highest peaks are Łysica, 612 meters (2008 ft), and Łysa Góra, 593 meters (1946 ft). Together with the Jura Krakowsko-Częstochowska, the mountains form a region called the Lesser-Poland Upland (''Wyżyna Małopolska''). They cover an area of 1684 km² (650 mi²). The approximate location is . ==Prehistory== The Świętokrzyskie Mountains are one of the oldest mountain ranges in Europe. They were formed during the Caledonian orogeny of the Silurian period and then rejuvenated in the Hercynian orogeny of the Upper Carboniferous period. The region was once on the southern coast of the ancient supercontinent of Laurasia. The oldest known evidence of tetrapods comes from 395-million-year old fossil footprints found in Zachełmie. The rocks were formed from a marine tidal flat or lagoon. The mountains have also yielded the oldest evidence of Dinosauromorpha, pushing back the evolution of dinosaurs to small, four-legged animals living during the Early Triassic. The fossil footprints date to some 250 million years ago, only a couple of million years after the Permian–Triassic extinction event, during a time when the environment was still destabilized. Footprints of early bipedal dinosaurs known as ''Sphingopus'', from 246 million years ago, have also been found. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Świętokrzyskie Mountains」の詳細全文を読む スポンサード リンク
