<p>The style of extensional basins provides key insights into the magnitude of extension and their kinematic evolution. The newly
documented Stilo rift (off Calabria, Italy) features a Serravallian–Tortonian rift basin bounded by a high-angle normal fault
and a Messinian adjacent supradetachment basin bounded by a low-angle normal fault. We propose a kinematic model suggesting
the abandonment of the high-angle normal fault and the beginning of low-angle normal fault activity, followed by a rapid increase
in extension. The triggering mechanism of the low-angle normal faults can be attributed to rapid rollback of the subducting
plate and/or to isostatic crustal uplift.
