The most dramatic change that occurred over time is the amount of recording and care taken to ensure preservation of artifacts and features.[3] In the past, archaeological excavation involved random digging to unearth artifacts. Exact locations of artifacts were not recorded, and measurements were not taken. Modern archaeological excavation has evolved to include removal of thin layers of sediment sequentially and recording of measurements about artifacts' locations in a site.[citation needed]
