Trinil and Kedungbrubus: the Pithecanthropus-bearing fossil faunas of Java and their relative age

Description
Summary:On biostratigraphical grounds it has been suggested (De Vos et al. 1982) that the Trinil fauna antedates the Kedungbrubus fauna in Java. This opinion, however, is at variance with evidence from stratigraphic superposition, which must take precedence, and also with magnetostratigraphic-radiometric dating. A reconsideration of the biostratigraphic analysis indicates that the Trinil fauna s.str. postdates the Kedungbrubus fauna s.str. The problem is complicated by the fact that the Kedungbrubus material in the Dubois collection comes from a wide complex of strata and that Dubois or his assistants purchased fossils from the local people, which has been denied by De Vos et al. A consideration of the faunal turnover confirms these conclusions. The Trinil fauna includes the species Rhinoceros kendengindicus, Epileptobos groeneveldtii and Elephas celebensis, and three temporal subspecies of Hippopotamus sivalensis are present at Kedungbrubus, although this has been denied.
