I have a 250 MYo favosite coral that was fully embedded in 650 MYo limestone.
But we'll never let the facts mess up a good fairy story...
Obviously.
So a fossil is always correlated to the era of the strata in which it is embedded, except when it doesn't fit the evolutionary presupposition. In that case it is obviously an example of erosion and redeposition.
Okay, I get it. Kind of like, "heads I win, tails you lose." I've always liked that kind of scientific proposition.
