“Just below” the KT Boundary can mean it died days before or thousands of years before depending on any number of variables. Things like how far below the KT boundary, the type of sediment, how densely packed it is, etc.

According to the history channel, there is a desert in Chile where the topsoil hasn't changed much for several million years.
