Supplementary material 4: Alternative models. A revised age-model for the Eocene deep-marine siliciclastic systems, Aínsa Basin, Spanish Pyrenees

Supplementary material 4. Alternative age-model scenario, with shift of the identified magnetic reversals to a younger part of the stratigraphy. The R1–N1; N1–R2 and R2–N2 reversals become the C20r/C20n, C20n/C19r and C19r–C19n, respectively. This produces a significant time offset with our key nannofossils markers and is, therefore, problematic.
