Fig. 3. A in First post-Mesozoic record of Crocodyliformes from Chile

Fig. 3. A. Indeterminate crocodilian right tibia (SGO−PV−833, Bahía Inglesa, Chile, late Miocene) in proximal (A1), medial (A2), and lateral (A3) aspects. Note the spiral fractures in A2 and A3. Such fractures involve torsional stress and indicate that the bone was fresh when the fracture occurred (see Lyman 1994 for a review of spiral fracture aetiology). Since impact during wave action or burial compaction seem unlikely to have caused the fracture, it may be direct evidence for predation or scavenging by other crocodyliforms. B. Indeterminate crocodilian tooth (SGO−PV−836, Bahía Inglesa, Chile, late Miocene). A1 and A2 are pencil drawings, A3 and B are photographs.
