I am curious- when coring did anything unusual turn up the samples.
Pull tabs the odd bit of modern or not so modern society,
I understand these are core samples from down deep, but there had to be some funny to layman bits of history in samples

I never saw anything in core samples that should not have been there, in terms of rock, fossils, etc., but the cores I examined were considered to be far older than human existence.
