Current version of the Paleolatitude.org model: 2.0.
We will keep this website up to date with the latest advances in plate
kinematic reconstructions and paleomagnetic reference frames. This page will
detail which updates have been carried out, and where the current website
differs from the original as published in van Hinsbergen et al., 2015,

Version 2.0, April 2016
The paleolatitude calculator has been updated to cover the entire Phanerozoic (550-0 Ma), where possible. The changes compared to the original calculator as described in Van Hinsbergen et al. (2015)
are the following.
- Paleolatitudes and error bars are now available for the full age range covered by the APWP of Kent and Irving (2010), i.e., 230-50 Ma;
- Paleolatitudes and error bars are now available for the full age range covered by the GAPWaP of Torsvik et al. (2012), i.e., 320-0 Ma.
- Paleolatitudes and error bars of the China blocks have been extended beyond 130 Ma using the China APWP of Van der Voo et al. (2015). North China paleolatitudes are available since 230 Ma, and South China paleolatitudes since 170 Ma, as explained by those authors.
- For times prior to 320 Ma, we have included the spline-fitted APWP’s of Torsvik et al. (2012) for Gondwana (Africa, India, Madagascar, Australia, Antarctica, South America), Laurentia (North America and Greenland), Baltica, and Siberia. The spline fitting methodology used by Torsvik et al. does not allow to quantify uncertainties, and pre-320 Ma paleolatitudes are therefore included without error bars.
- Because some of the major post-200 Ma continents consist of fragments that were on separate plates prior to 320 Ma, the plate model has been slightly modified. The Eurasian plate (originally coded 301) is now separated into Baltica (301), Siberia (401), and the Eurasian Variscides (315) that does not extend back farther than 320 Ma. We added the Alleghanian orogen of North America (199), which prior to 320 Ma was not part stable Laurentia. The original polygon 601 for the amalgamated China blocks is now broken down into North China (601), South China (602) and Amuria (453).
