This is because new sediments are always laid down on top of sediments that have already been deposited.
The fossil record preserves little fragments and snapshots of life through time, so while we may never find the first real dinosaur, we can have a good whack at what the earliest dinosaur species was based on what the fossil record yields to us.
Importantly, all of these new estimates seem to post-date traditional estimates for the origins of these groups that rely mostly on simple occurrence dates of the fossils, and don’t account for their evolutionary relationships.

This is important for evolutionary studies as it means that we can now more accurately assess the times of important steps in the global tree of life, and apply these to our large-scale understanding of the macroevolution of life on Earth.

Knowing when a dinosaur or other animal lived is important because it helps us place them on the evolutionary family tree.
Accurate dates also allow us to create sequences of evolutionary change and work out when species appeared or became extinct. These are: Where possible, several different methods are used and each method is repeated to confirm the results obtained and improve accuracy.
