FIG. 3. — Probabilistic age model of the Honda Group at the La Venta site. Reinterpretation of the magnetostratigraphy chrons is based on our age model. The ages of the chrons are based on Hilgen et al. (2012). For information about the difference between the probabilistic age model and that of Flynn et al. (1997), see Supplementary materials Appendix 15.
