While post-Eocene Received in revised form 28 May 2014 ◦ Liguro-Provençal back-arc extension, and associated Miocene ∼50 counterclockwise (ccw) rotation of Accepted 8 June 2014 Sardinia–Corsica have been well documented, pre-Oligocene reconstructions suffer uncertainties related Available online xxxx to the position of Sardinia–Corsica with respect to Iberia. If a previously constrained major post-middle Editor: Y. Ricard Jurassic, pre-Oligocene rotation of Sardinia–Corsica can be quantified in time, we can test the hypothesis ◦ Keywords: that Sardinia–Corsica was (or was not) part of Iberia, which underwent a ∼35 ccw during the Aptian Sardinia (121–112 Ma).
