Location: Perning, near Mojokerto, East Java, the 1936 discovery locality of a fossil child’s skull widely attributed to H. erectus, and laterally equivalent sediments at Jetis. Taxon: Terrestrial, mangrove and aquatic plants. Methods: A comprehensive suite of samples was collected at close spacing through a coastal sedimentary succession analysed concurrently for its depositional origins. The section traversed particularly informative marine, delta front and delta plain deposits, including the bonebed in which the H. erectus was discovered. Results: Rich palynomorph recovery indicative of mangroves was obtained in the mud-dominated marine Mollusk Member II at the base of the analysed section. The overlying deltaic strata are characterized by grass pollen and phytoliths, while still retaining mangrove and wetland signals in key samples near the level of the H. erectus bed. Main conclusion: The vertical stratigraphic series of facies in the Perning and adjacent Jetis sections indicates a landscape with four potential Homo habitats: muddy deltas with widespread Nypa swamps; a poorly vegetated sandy delta; extensive open savanna grasslands in the lowlands up river of the delta; and volcanoes in the upper reaches of the catchment with perhumid montane podocarp and broad-leaf forests and probable open fire-climax Casuarina junghuhniana forest. Palynological data support an Early Pleistocene geological age for Mojokerto H. erectus at about 1.43 Myr.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Early Pleistocene climate,Early Pleistocene landscape,food plants,glacio-eustatic cycles,Pleistocene savanna,time of Homo dispersal to Java[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: “The costs of processing the palynological samples was borne by a grant from the National Science Foundations (BCS 0113688) and the Leakey Foundation to O.F.H. and related research was done under permits from Lembaga Ilmu Penetahuan Indonesia (LIPI) for the ?Geology, Stratigraphy and Palaeontology of the Perning Area, Mojokerto, East Java?.
