The main objective of this work is to show that the distribution of transitional paleomagnetic data recorded at 250 Ma are in agreement with simulated data that depend on the sampling site, using a model that considers features of the Present Earth magnetic field. The modelled and recorded data show a remarkable fit when absolute reconstructions of Pangea A and A2 configurations are performed. The agreement between both simulated and recorded data suggests that similar features of the Present Earth magnetic field could have been involved in the reversals since the Permo-Triassic.
