A critique of magnetostratigraphic coverage for the Phanerozoic is presented. Cambrian to EarlyCarboniferous constraints are sparse in the absence of dedicated magnetostratigraphic studies. The LateCarboniferous and Late Permian boundaries of the Permo-Carboniferous Reverse Superchron (PCRS)are better constrained from magnetostratigraphic studies, but limited detail is available on possiblenormal polarity subchrons in the PCRS. Triassic to Recent constraints are well-established fromdedicated magnetostratigraphic studies with adequate biostratigraphic control, and for the MiddleJurassic to Recent from calibration against marine magnetic anomalies.
