Late Neoproterozoic palaeogeography: The Laurentia-Baltica puzzle

Palaeomagnetic and geological data constrain a variety of Laurentia-Baltica reconstructions that have been proposed for the late Neoproterozoic. The presence of palaeomagnetic data that suggests both high and low latitude positions for both continents around the end of the Neoproterozoic prevents the development of a single palaeogeographic model and two alternative animated models are presented.
