PBDB Interval

Longobardian subage

239.7 - 237 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 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 2 timescales which overlap this one. show

This interval is used in the definition of 420 collections

A total of 1604 collections with 8434 occurrences lie within this time span
