It’s interesting in the fact that we carbon date fossils ect but never thought about plants

Player #55741825,
(I am not sure but) maybe they use more general radiometric dating.
When a plant/ animal "fixes" a gas from the atmosphere the ratio of isotopes is known. With the decay rate of the isotopes, the time can be found.
But now many elements/ isotopes are used.
They compare ratios Nitrogen, Oxygen, Carbon... isotopes.
The comparison is based on whether aging in years up to hundreds of millions of years.

It can be a houseplant grown from seeds. Also can live over 1000 years. Cones are edible.

This tree would be mistaken for an ugly weed if it were in my backyard. Pulled out by its roots! I'm glad it grows somewhere else though, fascinating. What tree family does it belong to?
