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.

Mastering the most ancient part of Zaryadye commenced earlier than XIII century, and it is there now focused the interest of archaeologists, who recovered from under the bushel layers of all known eras artifacts give reason to confirm or obroski for different failure hypotheses. For example, the fact that the actual Moscow considerably exceeds the time that has passed since its first mention in Chronicles. Finishing the current season of excavation under the open sky, scientists from the cohort of “the science of shards” have something to brag about.
In the area, told the press expert Konstantin Voronin, “the density of finds are extremely high – about a dozen of individual items per square meter of excavation”. And the most impressive in size was a wooden bridge of the XVII century, found to the East, and marked the route “known to historical plans curve lane”. Swedish coin,fragments of the score and wrote to prove that a convenient place for mooring boats has become a brisk trade area with benches changed and even the possibility of accounting for and control of imported because tridevyat land products.

The researchers from Italy used sophisticated scanners to check the status of the remains of victims of the eruption of Vesuvius in 79 ad, the inhabitants of Pompeii. Multi-layer scanning showed very interesting results. For example, the fact that the victims were just great teeth. In addition, most people died not from suffocation, but because of head injuries.
The analysis is part of a larger project involving archaeologists, it professionals, orthodontists, radiologists. The remains of the victims of the eruption of Vesuvius covered with plaster in the 19th century for the preservation of human remains and capable of transporting them. But the cast made it impossible to study the remains, the layer is too thick for a regular examination. The fact that archaeologists of the 19th century unearthed the city, and found voids in the strata of volcanic ash that were previously occupied the bodies of humans and animals. These voids (inside which are preserved the skeletons of the dead) were filled with plaster, and then uncovered. In summary, the researchers managed to obtain a very realistic casts of human bodies, complete in every detail. Continue reading
