Digging for discovery is a common practice in archaeology. Fossils, sherds, relics, potshards, shards, artifacts, and bones are all items that can be found during a dig. Fossils are the remains of plants or animals that have been preserved in the earth for thousands of years. Sherds are pieces of pottery or glass that have been broken off from a larger object. Relics are objects that have been preserved from an earlier time. Potshards are fragments of pottery that have been broken off from a larger object. Shards are pieces of stone or glass that have been broken off from a larger object. Artifacts are objects made by humans that have been preserved from an earlier time. Bones are the hard parts of the body that have been preserved in the earth. All of these items can be found during a dig and can provide valuable insight into the past.
