Extended Data Fig. 3: Transdimensional Markov chain Monte Carlo (MCMC) simulation and conjugate partitioned recursion (CPR) of the percentage of mudrocks through time.
From: Composition of continental crust altered by the emergence of land plants

MCMC yields a statistically valid change point 430–420 Myr ago with a maximum likelihood at 423 Myr ago (using one million simulations) whereas CPR shows a change point at 430 Myr ago. Data from ref. 17.
