Tenuicostatum chron
184.2 - 182.9 Ma
The definition of this interval in the timescale Ammonite Chrons of Northwest Europe is taken from the following source:
- J. Palfy, P. L. Smith, and J. K. Mortensen. 2000. A U-Pb and 40Ar/39Ar time scale for the Jurassic. Canadian Journal of Earth Sciences 37(6):923-944 view
The top 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 6 timescales which overlap this one. show
This interval is used in the definition of 346 collections
A total of 1725 collections with 9341 occurrences lie within this time span
