| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "The specimen is from 35 m below the T-1 marker tuff, which had been dated as
161.2 6 0.2 Ma. Recalibration of the age of the Fish Canyon sanidine monitor mineral suggests that the age of the T-1 marker tuff should be adjusted 0.6% older. Thus, we regard its age as 162.2 plus/minus 0.2 Ma" (Andres et al 2014) | |||||
