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.

For a long time it was believed that the inhabitants of Easter island, or Rapa Nui (the local name for the Islands), were the victims of military conflict. The only thing left is the mysterious stone statues and a set of triangular shards of volcanic glass, which, presumably, was used as a weapon. However, it was different, believe scientists from the University of Binghamton in new York (USA).
In their opinion pieces, called “meta a”, actually served as tools. The findings of archaeologists refute existing theory about the bloody battle that destroyed the civilization on the island. New assumptions based on the results of the analysis of over 400 samples “mate and” collected on Rapa Nui.
According to the head of research, Professor Carl Lipo, a careful study of the fragments shows that they differ in shape, unlike the model spearheads. Comparing the samples from Easter island with the fragments of weapons found in Europe and around the world, you will notice that all the elements of the latter have the same carefully designed and tested the form, says the scientist. And she, in his opinion, was necessary that weapons are guaranteed to reach the desired goal. Continue reading
Finds from the excavations are exhibited in the Monographic Museum.
Of Pollentia, or Pollentia is an ancient Roman city on the island of Mallorca, between the bays of alcúdia and Pollença, Alcudia closer to (the ruins of Pollentia are next to the wall of a medieval fortress Alcudia). It was founded in the year 123 BC by the Consul’s partial Ceciliam and was the capital of Mallorca and the most important city of the Balearic province.
The first excavations of the Roman town was carried out in the sixteenth century – due to accidentally found the head of the statue of the Roman Emperor Augustus. Regular archaeological surveys began in the last century, in 1923, under the direction of Professor Gabriel Quintana Llabres.
What you can see in Pollentia today?
Today Pollentia is 12 acres of excavation (approximately the city occupied approximately 16-18 hectares). Closest to Alcudia ruins of an ancient theatre. In addition, you can see Portello – residential area (also sometimes say “Portala”), where partially preserved building, which now bears the name of “House heads”, Continue reading
