Sedimentological and paleogeographical context of the Mojokerto hominin
site, East Java :92 abstr.67th ann.meet.Soc.Vert.Paleontol.

.... the discovery site lies above marine Mollusk Mbr II & within a
fossiliferous pebbly sandstone in the upper Pucangan Fm. The sandstone is a
fluvial deposit with a broad channelized base, prominent cross-bed sets &
other bedding indications of mid-Channel river bars incl.preserved dune
surfaces (mega-ripples) on the bars, & is confortably overlain by a 45 m
paleosol developed in a mudstone. This bed is, in turn unconformably
overlain by sand+mudstone containing burrows & marine mollusks representing
the bas.bads of Mollusk Mbr III. These lithofacies represent a variety of
deposit.environments ranging from flood plain to delta slope , together
preserve evidence of the localized progradation of a delta lobe into a
shallow water marine embayment. ... present-day deltas in this region can
experience very rapid progradation rates, the Perning lobe may have been
deposited in <104 yrs , is not necessarily linked to a glacio-eustatic
sea-level lowstand. Given that the Moj.hominin spm appears to have
experienced min.transport, we conclude that Homo erectus inhabited seacoast
environments.
"We conclude that He inhabited seacoas environments." And then the
inevitable SFs' sentence:
"This paleoenvironmental reonctruction is in strong contrast to the more
typical savanna-woodland setting of this species in Africa (they mean the
usual savanna-biased interpretations à la Olsen boy --MV), suggest that He
had a broad adaptive niche."
