Bithynian subage

245.5 - 244.7 Ma

The definition of this interval in the timescale Mesozoic Subages is taken from the following source:

  • F. M. Gradstein, J. G. Ogg, M. D. Schmitz and G. M. Ogg. 2020. Geologic Time Scale 2020 view

The top and bottom ages have 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 2 timescales which overlap this one. show
