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
Novosibirsk region is famous for its variety of terrain: plains, lowlands, and swamps, and steppes. But today it’s about Palaeolithic Parking lot “Wolf Mane”, located in 62 kilometers from the city Karagat. In 1957 archaeologists discovered this unique place. which at first took to be a huge cemetery of mammoths, but it was later revealed that this prehistoric people, who never used in their simple life stone. Scientists dug up any of a thousand skeletons of dead animals, which indicates the exceptional significance of mammoths in the area. Animal skins served as building material for homes of people of that time, bones made tools, meat from animals fed. Found the remains of animals of different ages — here and old mammoth, and young, scientists found not only the remains of mammoths, and bison, horses and other animals. Collection of stunning finds of the stone age at the present place is stored in the Institute of archaeology and Ethnography of the Academy of Sciences of Novosibirsk. Territory “Wolf Mane” impresses with its size: Parking stretches for 8 kilometers to the East, has a width of 1 kilometer, and stands 11 meters. The area is valuable not only from a scientific 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
