Not so far fetrched. A sediment flow rate for the Mississippi was established using various dateable aluminum cans with the various opening desings. Clay pipes used in taverns underwent a progession of stem diameters that are used to date New England sites. I excavated the Rectory at the Plaza Church in los Angeles. I uncovered a complete bottle of wine among the shards. I was about to uncork it when teh site leader had a fit. It's at the museum, probably worth a small fortune to wine colectors.
