Bohemia and Moravia were once our own continent ... Perunika
More than half a billion years old today consisted of Bohemia and Moravia microcontinent Perunika, close to the South Pole. On this microcontinent prior to the beginning of the Ordovician, around 490 million years ago, was deep along the house long, shallow dip of the Prague Basin in SW-NE direction. It was just over 20 km wide, reaching from oceanic successions in Perunica coast in the west to its center, to the present-day Iron Mountains.
Graduates, křížovkáři hunters and earth-aware cache Paleozoic formations Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. Today, three of which you can see with your own eyes and you can touch them!
Valley is flooded with sea level at the beginning of the lower Ordovician. The sea remained throughout the Ordovician, Silurian to Middle Devonian, more than 100 million years. Throughout its ancient history Perunika moved towards the north, to Equatorial zone. There arrived in the lower Devonian about 410 million years ago.
The default coordinates are standing at the bottom of the sea. Retreated after millions of years and its deposits formed across the mountains, but it disappeared. At that time pushed Perunika north African continent to hit the Baltic (Scandinavian) in the north.
Pressures between these continents bottom of the Prague Basin vyklenovalo, změlčovalo and the sea retreated from the Middle Devonian in front of about 390 million years ago. In the following period, Late Devonian and Carboniferous sediments folding took place in the pan to low arose Paleozoic mountains.
We are hard at uncovering the highest Ordovician sandstones below the idea of flat rock, established at the time the largest global glaciation in Earth history. On the surface obliquely inclined layers are traces of climbing Paleozoic fauna. Traces of currents and waves (ripples) - were destroyed even before the construction of the nation, natural sights.
