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.

Neolithic
|
About 4000 BC to 2351 BC
The word ‘Neolithic’ means ‘New Stone Age’. Archaeologists split up the Neolithic period into three phases; early, middle and late. The Neolithic period comes after the Mesolithic period and before the Bronze Age.
People in the Neolithic period hunted and gathered food as their ancestors had but they were also began to farm. They kept animals and grew crops. This meant that they were able to settle more permanently in one location instead of constantly moving from place to place to look for food.

Iron Age
|
About 800 BC to 43 AD
The Iron Age comes after the Bronze Age and before the Roman period. It is a time when people developed the skills and knowledge to work and use iron, hence the name ‘Iron Age’ which is given to this period. Iron is a much tougher and more durable metal than bronze but it also requires more skill to make objects from it. People continued to use bronze during this period.
