Did bones actually become fossilized in the sediments of "ancient" epeiric (inland) seas on continents?

If some giant wave deposited thousands of feet of sediment on the west coast, then where did the same aged sediment (Paleozoic) which makes up say, the taconic or Acadian mountains, come from?

From the same Sauk transgression that supplied the west coast.
