You can use fossilization as a way of dating too. Archaelogists use Dendrochronology to date strata that might not include some sort of tracking or widescale fossil, but might have a tree or two. Depends on the sedimentary rock. Igneous and Metamorphic rocks generally speaking, cannot, be used for bio-dating due to their lack of retaining fossils. But sometimes Marble can be used as it's metamorphosed limestone (aka Calcium Carbonate) and that rock type is widescale. Formed in shallow oceans.
