It might be something as silly as change of wind that brought dust instead of sand or maybe different type of sand.
Basically anything that covers the fresh print with a layer that is different enough chemically or physically that will then cause the layers to develop/preserve a boundary that can then break clean off millions of years later after everything is pressed/mineralized/whatever other processes happened.
