Couvinien age
408.2 - 387.7 Ma
The definition of this interval in the timescale Devonian of France is taken from the following source:
- W. B. Harland, R. L. Armstrong, A. V. Cox, L. E. Craig, A. G. Smith and D. G. Smith. 1990. A Geologic Time Scale 1989. view
The bottom age has been interpolated based on the differences between the ages for international timescale boundaries quoted in the source and the currently accepted ages for those boundaries.
There are intervals in 5 timescales which overlap this one. show
This interval is used in the definition of 5 collections
