Can radiocarbon dating date

Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.But new research shows that commonly accepted radiocarbon dating standards can miss the mark—calling into question historical timelines.

"Our work," he added, "should prompt a round of revisions and rethinking for the timeline of the archaeology and early history of the southern Levant through the early Biblical period."

Mackenthun instead argues that there is no evidence of genetic continuity between the dead and living wood portions of the tree, nor is there any evidence of clonal origination of Norway spruce in general.The living tree is argued to be only the most recent ramet of the much older individual genet. Thus, in the absence of any solid evidence of genetic continuity between dead and living portions of a species otherwise not known to commonly reproduce clonally, I do not include such trees in data.

However, radiocarbon ages of trees are considered if the date came from a piece of wood that can unequivocally be associated with the individual tree itself. (2007) used radiocarbon dating on pieces of what may be the largest known baobab (Adansonia digitata) to determine that the tree was at least 1250± 50 years old when it recently died.
