Response to the comment by Huffman and Zaim

Abstract

Huffman and Zaim criticize our analysis of the stratigraphic

context and age of the Homo erectus child skull from Mojokerto. The

disagreement stems from our different points of departure. Huffman

and Zaim base their analysis and conclusions on sedimentological interpretations and stratigraphic models of the 1930's, wherein strata and their assumed ages are correlated over large distances across eastern Java (Duyfjes, 1936, 1938). In contrast, our recent studies in the Trinil (Berghuis et al., 2021) and Mojokerto areas (Berghuis et al., 2022) have revealed an area-specific intricate build-up of shallow marine and fluvial sequences, often separated by irregular incisive contacts, testifying of highly dynamic Pleistocene landscapes subject to volcanism, tectonism and sea-level fluctuations.
