Aerial Photograph
|
Aerial photographs are taken during an aerial survey, which involves looking at the ground from above. It is usually easier to see cropmarks and earthworks when they are viewed from above. Aerial photographs help archaeologists to record what they see and to identify new sites. There are two kinds of aerial photographs; oblique and vertical.

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 ->
