This is a timeline of the Fertile Crescent going from 9000 BC to the end of the BC era.
This is another timeline of the Fertile crescent from 9000 BC to 700 AD.
Out of both of these time lines, I would choose to add the second one to our textbook. Out of both of these timelines, I believe that the second one is better. Even though both timelines have approximately the same number of events, the second timeline provides images. These images help correlate what actually happened in the Fertile Crescent to today much better then the first one. Overall, I believe this timeline would be a great addition to the textbook, and would greatly help out with learning about the fertile crescent.
