(2017) dealt with the magnetostrat and geochronology of Patagonian faunas and suggest much younger ages for Riochican and Vacan and considered Sapoan not suitable as time interval." (Speijer, 3Sept’19 to J.Ogg). Diagram in Krause et al’17 indicates overlap of upper Riiochican and much of the Vacan fauna.
