PARADOX IN STRATIGRAPHY:
WHERE ARE THE ANCIENT ROCKY LANDSCAPES AND SEASHORES?
When researching ancient rocky landscapes, we face a serious paradox. Ancient rocky seashores and true rocky landscapes are missing from the Paleozoic and Mesozoic eras. The ancient erosions surfaces are at odds with what we see today. They are mostly flat and lacking the normal erosion and alteration as we see in the present Earth. To tease your curiosity we invited our readers to have a first look at these odd surfaces recorded along what we call the unconformities. An unconformity marks the limit between a younger sedimentary rock laid above an older eroded rock.
