Information about the Roman empire was comparatively easy to uncover because many of the ancient Roman structures are still standing and some are still even being used. Plus, archaeologists had the literature that the Christian monks preserved and many physical artifacts. However, new things are being discovered about ancient Rome every day. The extent of their civilization in Wales is a current example.
The egyptions stopped making mummies because first a fall they believed that if they will wrap the dead body with the white cloth and keep some belongings of that dead body like clothes ,cups in which they drink something so in a day or two that dead person will be alive but when scientists and acheologists reserched on that particular thing they found that the dead body eaten by the insects and then they told this thing to the people of egypt so they stopped making mummies.
When an archaeologist is deciding upon a site, he (or she) will often begin by asking whether anyone else has done research in that area. This previous research could show if there are known sites already which could be useful. It also helps to check with a National Register of sites for the country in which the archaeologist is working. This can often involve looking at old maps or other documents, both historical and modern. Ethnographic accounts (native documents from the region) are also a key source of information. Moreover, many archaeologists will travel to the region they are looking to research and talk to the locals, since they may have knowledge unavailable on a wider scale. Sometimes however it all comes down to chance discovery.Another question to ask is whether anyone has worked out a basic chronology for the site to get a sense of what could possibly be there. Most importantly, the archaeologist must know what question he/she is researching. This question will define the scale of analysis for the researcher as well as what specifics the archaeologist will be looking for in a particular site. In essence, the site which the archaeologist seeks to find is one which will help answer his or her research question.
