Cropmark
|
Cropmarks appear as light and dark marks in growing and ripening crops. These marks relate to differences in the soil below. For example, parched lines of grass may indicate stone walls. Crops that grow over stone features often ripen more quickly and are shorter than the surrounding crop. This is because there is less moisture in the soil where the wall lies.

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 ->

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. more ->
