Writer Dr. Antonio M. Wilson is involved in conducting research that leads to archeological digs or excavations as an extension of his findings. Dr. Antonio M. Wilson has contributed to excavations which led to the discovery of artifacts dating back to biblical times.
There are a variety of tools available for use in archeological excavations. One of the most-often used tools is the trowel. While masons use it to apply mortar to bricks and stone, archeologists use it for excavating in areas that are too small or too critical for shovels to be used. A rounded or square shovel, on the other hand, is often used as the main tool for excavation in non-critical situations, as it can move more soil in a shorter period of time. It is used in areas where few if any artifacts are likely to be discovered.
Screens are utilized to filter the soil from each location to better find small artifacts. Another tool is a soil core. This is a small metal tube having a handle at the top and used for sampling specific areas in the ground to learn about the composition of the layers of sediment that have accumulated over the centuries. After marking a specific spot to core, the researcher uses his or her weight to push the core into the ground and then pulls it out, and later carefully analyzes the various layers of soil inside it.
More sophisticated (and expensive) tools include global positioning systems, magnetometers, and ground penetrating radar. These non-invasive tools are used to find locations that may be of archeological interest.
