Skullcap (Trinil 1), Femur I (Trinil 3) and associated paleontological specimens has been impaired for over a century by questions about their provenience. Firsthand accounts and contemporaneous field photographs, presented here, extensively document the site geology and discovery history. The P.e. specimens and numerous-other fossils were unearthed in 1891- 1893 from small excavations dug into a flat-lying bonebed exposed near the seasonal low water level of the Solo River along its incised left embankment. Dubois' on-site supervisors specified that the two P.e. fossils came from a ~0.2-m-thick bonebed subunit traced at a single elevation for ~12m from the 1891 Skullcap pit (~30m 2 ) to the 1892 Femur-discovery excavation and across an enlarged 1892-1893 trench (~170m 2 ). The depositional co-occurrence of the finds is supported by key documentation: the supervisors' letters to Dubois about Femur I;...
