I've been realizing I really want to know how geologists are so sure that a particular stratum found anywhere on earth belongs to a particular time period. What are the methods for determining this? Fossil content? Relation to other layers? Are there some areas where it is hard to determine?
​
I'd like to sit back, ask questions and otherwise watch on this one.
