Fossils are the remains and imprints of plants and animals that lived on Earth in the long past era. But turns into a fossil only a small part of plants and animals. As a rule, their remains are either eaten by other animals or decomposed by the action of fungi and bacteria. Shells or hard bony skeletons persist longer, but eventually they are destroyed. It was only when the remains are buried in the ground very quickly, before they have time to decompose, they have a chance to survive and turn into a fossil. To the deceased plant or animal was buried rapidly, it is necessary that over it there was a sediment, for example sand or silt. Then his remains were soon denied access of air and not rot. Over millions of years of sedimentary layers of the lower pressure of the upper turn into solid rock.
Water that seeps into sedimentary strata, contains minerals. Sometimes she washes them out of the sedimentary material. Under the weight of the upper sedimentary layers of the water displaced from the bottom. Minerals remain within and contribute to the bond of the sedimentary layers and their solidification into rock. These minerals are deposited even in the remains of plants and animals, filling the spaces between their cells, and sometimes even “replacing” their bones or shells. So obratimosti naturally grow in the stone and remain there Continue reading
No place in the world, contains the same number and diversity of fossils of the Jurassic period.
A team of paleontologists led by Dr. Juan Garcia Massini announced the opening of the largest Park of Jurassic period fossils in Patagonia in southern Argentina. The place of burial of the fossils, which were uncovered by recent erosion, it was discovered four years ago and until now was kept secret.
Dr Massini, a geologist from regional research centre reported that this plot is in the area of the massif the Deseado in the province of Santa Cruz in Patagonia.
“This is a unique discovery. Found bones and fossils of flora, micro – and macro-organisms. In addition, the organisms were buried very quickly by mud and fine earth, says Massini. – You can even see how the fungi, cyanobacteria, and worms were moved when they were still alive”.
Excavations are carried out on an area of about 60 thousand square kilometers, and the Massini amazed at how well preserved this area, which is 140 million years old. Continue reading
In the Stavropol earth are buried the remains of the ancient cities and even the earlier settlements of primitive man, stone boxes — tombs and majestic mounds, the dolmens and the massive underground chambers of the catacombs. As legendary statues, towering in the mountains of the greater Caucasus and its foothills Christian temples of X—XI centuries, some of the earliest on the territory of our country, majestic fortresses and towers of middle ages.
In the region identified 177 archaeological sites that scientists investigate how improved tools from the stone cut to perfect the bronze and iron guns. Great interest among the archaeological monuments of ancient times are the Parking lot of Sycamore on the Big Zelenchuk, barrow graves near Ust-Jeguta, tombs of the nobles of the bronze age, dolmens in the mountains of Karachay-Cherkessia, colorful bronze Koban culture. Highly artistic products rich Scythian barrows in C. Alexander, Hrushevsky the town near Stavropol, where for centuries was stored samples of the highest culture of ancient Greek (the remains of amphorae, with the names of Greek masters, bronze and iron pins, buckles and other products).
