So. For context. Watching a nature documentary the voice over guy gave the year that a species of tree died. The tree wasn’t a fossil. More like a dead stump you could walk up to and see.
I understand how they age trees to see their approximate age but how can they predict an exact year that tree died?

First, it’s possible that he had that data from another source. If a permit was pulled to cut down that particular tree, like in a construction site, then that would tell you how long it’s been since it was cut down.
Alternatively, tree rings make a record of how much growth a tree goes through each year. With a lot of knowledge about the area, you might be able to line up things like droughts or floods from the historical record with the pattern of the rings.
