At least three of the huts were occupied at approximately the same time.About 149 individual mammoths are believed to be represented at the site, either as building material (for the structures) or as food (from refuse found in nearby pits) or as fuel (as burned bone in nearby hearths).The archaeological site of Mezhirich (sometimes spelled Mezhyrich) is an Upper Paleolithic (Epigravettian) site located in the Middle Dnepr (or Dneiper) Valley region of Ukraine near Kiev, and it is one of the best-preserved sites of its type excavated to date.Mezhirich is a large open air site where several mammoth bone huts with hearths and pit features were used between about 14,000-15,000 years ago.The dwellings are separated from one another between 10-24 m (40-80 ft), and they are arranged in a V-shaped pattern on the promontory top.The main structural elements of the walls of these buildings are stacked mammoth bone, including skulls, long bones (mostly humeri and femora), innominates, and scapulae.

Mezhirich has been the focus of a suite of radiocarbon dates, primarily because while there are numerous hearths at the site and an abundance of bone charcoal, there is almost no wood charcoal. Mammoth bone deposits and subsistence practices during Mid-Upper Palaeolithic in Central Europe: three cases from Moravia and Poland. There are many other Carbon isotopes, but the one we want to look at is called Carbon-14. Carbon-14 is produced as a reaction to cosmic rays in the Earths atmosphere. is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly in each atom.It can be used on objects as old as about 62,000 years. Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.
