If paleontologists find a steep slope, folded sedimentary rocks, full of fossils, what they can say about their interaction?
Rocks, forming in some places, differ substantially from the others. Their specific characteristics are called sedimentary facies. It happens today, just like millions of years ago. Rocks at different sites can have very different composition, even if their accumulation occurred in the same period of time. The same applies to those included in them the petrified spines.
Fossils in some places is often very different from that of fossils in other places due to the environmental conditions in which the sediments. Just like ocean fish, shellfish, and mammals that live at different depths, the fossils found in various sedimentary deposits of ancient seas, characteristic of the marine environment. The stratigraphic arrangement of the sedimentary rock often shows the species and a sediment gradient. Because ultimately everything falls to the bottom and covered by sediment, even species that lived at a great distance from each other (in depth), can be close to each other in the layer of sedimentary rocks.

A group of scientists and archaeologists from the universities of Durham and West Florida have conducted studies of ancient human remains that were buried about two thousand years to ancient Roman cemeteries. The researchers used a method of isotope analysis by which scientists were able to determine the conditions under which was formed the tooth enamel of ancient people, what they ate and the water drank in life. Thus, experts were able to establish, who was a native of Ancient Rome, and who came from other places.
Journalists Express News . referring to the materials published in the expert edition of PLoS One, has told its readers that eight of the examined human remains there are obvious signs that their diet has undergone major changes. In particular, it was found that these people came from Northern Africa, though figure out whether it was a voluntary action or compulsory, is not possible. Moreover, in those days it could be as the people who arrived in Ancient Rome with the purpose of training, and slaves. Continue reading
Black diggers by pretending to be employees of the Vsevolozhsk Museum, stole a Soviet attack aircraft
During the great Patriotic war the IL-2 was the most mass combat aircraft. Under the guidance of aircraft designer Sergei Ilyushin was released 36 thousand stormtroopers.
Our designers have called him “a flying tank” and the Germans for survivability and the lack of maneuverability was called “cement bomber”. Later, considering the power of the machine, hate the nickname “butcher” and “black death”.
Such planes are trying to recover at the Novosibirsk plant. But to find almost the whole IL-2 is priceless.
Fifteen aircraft had raised for his practice, and such a well-preserved copy was not found, — have shared the joy of the commander of the military-Patriotic search group “Vityaz” Nikolay Bukhtiyarov. — It happens once in a lifetime.
Fragments of the IL-2 they with children unearthed last week in the Luga district in three kilometers from the village Volodarskoye. First, the plane was noticed by the Rangers, they passed the information to the administration, and those attracted search engines. Continue reading
