Figure 3. A in A new turtle from the Palaeogene of Patagonia (Argentina) sheds new light on the diversity and evolution of the bizarre clade of horned turtles (Meiolaniidae, Testudinata)

Figure 3. A, general view of the outcrops of the Sarmiento Formation in the middle–upper section at Cerro Verde area (viewed from north to south) (see also Pol et al., 2012, Fig. 2A). B, upper 15–20 m of the Rocas Gemelas section. The floor of this part of the outcrop corresponds to the fossiliferous level, just below the channel facies. C, upper 10 m of the Pipe-Rock section. The conspicuous pipe-rock ichnofabric occurs toward the top of the outcrop. D–E, silica in irregular nodules (F) and as rhizocretions (E). F, weakly developed palaeosol, displaying granular structure (vertical rule is around 30 cm). G, vertical burrows defining a pipe-rock ichnofabric. H, mould of pulmonate gastropod (Strophocheilus sp.). I, mammal tooth remains.
