We present paleomagnetic results from 141 samples collected at 12 sites from Plio-Pleistocene clayey units in the extensional Central Italy Tyrrhenian margin. All samples were subjected to stepwise alternating field and/or thermal demagnetization. Positive fold and reversal tests indicate that the results refer to a primary component of magnetization. Paleomagnetic mean direction (Declination=358.0¿; Inclination=55.2¿, &agr;95=4.1¿) reflects the expected geocentric axial dipole field for the locality, thus indicating that this sector of the Tyrrhenian margin did not undergo any tectonic rotation during the past 4 million years.
