Distribution of bioprovinces and oceanic circulation pattern plotted on a Pangea B configuration of 300 m.y. ago. Bio-provinces distribution modified from Shi (1998). Cool to warm Verkolyma, Alaska-Yukon, and Uralian Provinces are part of Boreal Realm; warm Texas, West Tethys, and Cathaysian Provinces are part of Tethyan Realm; cold Indoralian and Paratinan Provinces are part of Gondwanan Realm. Extension of glaciers and distributions of cold marine faunas are modified from Angiolini et al. (2005). Distribution of Appalachian, Variscan, and Uralian thrust belts is from Matte (2001) (modified).

Tomographic images of the subducted Australian plate beneath Java (profile A1 - A2) and the Cocos plate beneath Central America (profile B1 - B2). Images are derived from a global P-wave velocity model ' KH ' [16] for both cross-sections, and from a regional Pand Swave velocity model ' RHSB ' beneath the Americas [18]. Colors show the deviations of the Por S-wave speed relative to the laterally averaged reference model ak135 [19]. Because the amplitude of the P-wave velocity model issmaller than that of the S-wave model, the boundaries of the fast anomaly are indicated by contours of 0.2% and 0.3% (for P) and 0.4% and 0.5% (for S). The heavy black bars indicate the buckling amplitudes predicted using the scaling laws of Fig. 2. Panels d) and e) show a synthetic resolution test of the RSHB model. The input P-wave velocity model represents a slab 200 km wide and 1000 km long in the direction perpendicular to the image, and inversion isperformed using the same path coverage as for the model RSHB. An analogous test using the S-wave data gives similar results (not shown).
