Archaeologists do not just dig holes of random sizes until something is found. The dimensions of separately hole is determined before excavation begins and is sectioned forward with rope, usu onlyy in one by one quantity social units. Once the excavation starts the hole is dug down evenly in levels. It is imperative when digging the unit to keep all walls smooth and straight and to excavate soils of different colors inside a level separately. These aras of different soil composition are designated as features and are caused by rodents, fire, organic material that has rotten and human activities. All soil removed is then displace in a sieve, which is a screen that lets soil chap through and traps artifacts that would go otherwise unnoticed like subaltern flaked stones and fish and rodent pearls. All artifacts and ivorys found in there original resting place are mapped and excavated using a masons trowel paint brushes and even chop sticks to subjugate all damage. All charcoal found, which is used for radio-carbon dating is placed in tinfoil and never touched by hand to avoid contamination. While the excavation is taking place, the more tedious position of archaeology, recording ones findings is also occurring. Recording and mapping all findings during excavation, darn time consuming, is the most important task an archaeologist has.
all(prenominal) level of a unit is described in dissimilar ways, including, start and stop depths, soil color and texture, and a contention of what was bagged and removed from the hole, for example charcoal, soil samples, artifacts and bones. Every artifact and bone is placed in a bag designated to a unit and level, which intern receives a catalog number. When features or artifact and bone concentrations occur a plan map of the level is raddled to show there specific location and when...
