An archaeologist studies ancient civilizations by examining fossils and artifacts found at archaeological sites. They dig at sites to uncover remains of past human settlements. Archaeologists find sites by looking in areas near water sources and trade routes where people historically lived. They also check reports of artifact discoveries. After getting permission, archaeologists carefully excavate sites by grid and record the location of all finds to piece together clues about past life. Their tools are simple but their work requires education, patience and attention to detail.
