Evidence for this is consistent with paleomagnetic data which place Avalonia at a temperate latitude during the Ordovician and in a subtropical latitude during the Late Ordovician through the Devonian.
As probas disto son consistentes cos datos paleomagnéticos que sitúa Avalonia nunha latitude temperada durante o Ordovícico e en latitudes subtropicais desde o Ordovícico tardío ata o Devoniano.
