Date Types and Terminology

• Cutting dates (B, G, L, v- dates)

• Last year of tree growth before death.

• Bark, bark patina, or beetle galleries must be present.

• Seasonality in Cutting dates

• Latewood is complete (“comp”- dates). Tree was felled after growing season.

• Last ring growth is incomplete (“inc”-dates). Tree was felled during growing season.

• Noncutting dates (“vv” and “++” dates)

• “++”-dates: possible absent rings near outside of ring growth. Probably deadwood use.

• “vv” dates indicate probable erosion of outer rings from a sample.

• Anomalous” tree-ring dates

• Those dates that don’t “fit” with the other beams from a structure/room, etc. Most likely caused by the reuse of timber, the use of dead wood, stockpiling, repair/remodeling, or other human behaviors.
