Short summary
Here we discuss the validity of so-called “break-up” markers along the Newfoundland margin, challenging their perceived suitability for plate kinematic reconstructions of the southern North Atlantic. We do this on the basis of newly available seismic transects across the Southern Newfoundland Basin. Our new data contradicts current interpretations of the extent of oceanic lithosphere and illustrates the need for a differently constraining the plate kinematics of the Iberian plate pre M0 times.
