- Abstract
In the Stratigraphic Table of Germany 2016 (STG 2016, in German), the timing of stages within the Devonian is derived using relevant radio-isotopic age determinations (RIA) from the period between 1990 and 2017. Rounding of the ages to whole millions of years is applied, to avoid misleadingly precise reporting of calculated values. The age of the Silurian- Devonian boundary in the STG 2016 is set to 418 Ma, but data would also permit a value of 419 Ma. The Devonian- Carboniferous boundary has an age of 361 Ma in STG 2016, based on formally published RIA, which is in contrast to the age value of 358.9 ± 0.4 Ma proposed in the Global Time Scale 2012 (GTS 2012). The ages of stage boundaries in time intervals lacking relevant RIA are estimated using the time ruler of Weddige (1996). The temporal relations between the seven global stages of the Devonian presented by Tucker et al. (1998) continue to be valid.
