excavation
|
Archaeologists excavate sites so that they can find information and recover archaeological materials before they are destroyed by erosion, construction or changes in land-use.
Depending on how complicated and widespread the archaeological deposits are, excavation can be done by hand or with heavy machinery. Archaeologists may excavate a site in a number of ways; either by open area excavation, by digging a test pit or a trial trench. more ->

Modern

The Modern Period, about 1915 AD to the present (the 20th and 21st centuries AD)
In recent years archaeologists have realised the importance of recording modern sites. They do this so that in the future people will be able to look at the remains to help them understand the events to which they are related. more ->

Prehistoric
|
About 500,000 BC to 42 AD
The Prehistoric period covers all the periods from the Palaeolithic to the end of the Iron Age. This is a time when people did not write anything down so there is no documentary evidence for archaeologists to look at. Instead, the archaeologists look at the material culture belonging to the people and the places where they lived for clues about their way of life.
The Prehistoric period is divided into the Early Prehistoric and Later Prehistoric. The Early Prehistoric period covers the Palaeolithic and Mesolithic periods. The Later Prehistoric period covers Neolithic, Bronze Age and Iron Age times. more ->

Medieval
|
1066 AD to 1539 AD (the 11th century AD to the 16th century AD)
The medieval period comes after the Saxon period and before the post medieval period.
The Medieval period begins in 1066 AD. This was the year that the Normans, led by William the Conqueror (1066 – 1087), invaded England and defeated Harold Godwinson at the Battle of Hastings in East Sussex. The Medieval period includes the first half of the Tudor period (1485 – 1603 AD), when the Tudor family reigned in England and eventually in Scotland too. The end of the Medieval period is marked by Henry VIII’s (1509 – 1547) order for the Dissolution of the Monasteries in the years running up to 1539 AD. The whole of this period is sometimes called the Middle Ages. more ->
