Recent studies have shown the extent and nature of the South China Sea (SCS) at the end of spreading by unfolding (i.e.structurally restoring) the Manila slab,which is the subducted part of the SCS,and by identifying the nature of the crustlithosphere (oceanic or thinned continental) from mid-slab P-wave velocity perturbations (dVp) [1,2].The objective of this paper is to propose a reconstruction of the SCS at the end of seafloor spreading and to discuss its geodynamic consequences in the context of the SCS and Philippine Sea plate (PSP) evolution.Reasonably accurate PSP paleo-latitudes and poorly defined paleo-declinations were primarily used to establish the kinematic evolution of the PSP through time (e.g.[3,4]) until 2016,when Wu et al.[1] introduced new kinematic constraints based on the unfolding and restoration of Southeast Asian slabs.
