Archaeologically an artefact is considered a portable, humanly modified object. throughout our lives our lifestyle, environment and diet have an affect on our skeleton and so through these processes human bones can be considered artefacts
No, not typically. An artifact is a piece of artwork or a tool, something used. Human finger bones were sometimes decorated as used in gambling games or cast to predict the future. In this respect they would represent artifacts. Most bones themselves were either burned (destroyed) or buried. They were often buried with artifacts, such as pottery shards and/or pieces of artwork. But the bones themselves would not typically be considered an artifact. Artifact: Any object manufactured, used or modified by humans. A prosthesis would be an artifact. Pins and splints used to hold bones together would be artifacts. The bones themselves--no.
