Short summary
This paper investigates the numerical age of the J–K boundary that remains one of the last main Phanerozoic system boundaries without an adequate constraint by adequate radioisotopic ages. Here we find that there is potentially 4 Myr of difference between the current age of the J–K boundary and our data.
