Figure 12 in Anatomy of the basal titanosaur (Dinosauria, Sauropoda) Andesaurus delgadoi from the mid-Cretaceous (Albian-early Cenomanian) Río Limay Formation, Neuquén Province, Argentina: implications for titanosaur systematics

Figure 12. Maps showing the distribution of titanosauriforms: (A) Late Jurassic, (B) Early Cretaceous, and (C) Late Cretaceous. Key: grey circles, non-titanosaur titanosauriforms; black triangles, titanosaurs; white hexagons, putative titanosaurs. See Table 7 for details. Images were produced in ArcGIS 9.2, and palaeomap reconstructions are from Scotese (2001) (note that the palaeomaps consist of the reconstructed positions of present-day continental coastlines). Modern day co-ordinates for titanosauriform taxa were converted to palaeolatitudes and palaeolongitudes (for the relevant time slices) using PointTracker (Scotese 2004).
