Stratigraphy

Reading the order of events from the order of the layers in the ground.

Layers of soil and debris build up over time, so what lies deeper is, with care, older. An excavation records which layer each find came from, and dates from one layer bound the layers around it. Göbekli Tepe, Gunung Padang and the Younger Dryas sites are all argued through stratigraphy: what is a buried structure and what is natural rock, which layer a sample dates, whether a layer was disturbed.

Where it comes up

Gunung Padang
The core is a volcanic body with natural columnar jointing; the deep layers are weathered and slumped columns and soil, and nothing inside was built.
Byblos syllabary
None of the 13 to 16 inscribed objects has a secure stratigraphic context, so the Middle Bronze Age date rests on Dunand's judgment rather than on recorded stratigraphy.
Eye of the Sahara and Atlantis
The missions of 1999 to 2006 produced no study of the material, no substantial stratigraphy and no absolute dates, and the region has no Palaeolithic stratigraphy on which to build a chronology.
Mars methane puzzle
Methane seeps from the ground at a low steady rate; at night, when the air near the surface is stable and the crater's winds converge, it builds up within metres of the ground where the rover samples it; by day, mixing…
Tarim Basin mummies (Xiaohe)
The earliest come from the lowest layers of cemeteries at Gumugou, Xiaohe and Beifang .
Göbekli Tepe
The people who built them hunted gazelle and wild cattle and gathered wild cereals; there is no evidence of domesticated plants or animals in the early layers .
Homo floresiensis, the origin of the Flores "hobbits"
At Mata Menge a fluvial sandstone dated to about 700,000 years by argon and fission-track dates on bracketing ash layers, with uranium-series and ESR dates on teeth, holds a jaw fragment, teeth and now a humerus of…
Amber Room
The Royal Air Force burned the city in August 1944; the room was crated and stored in the castle; a letter of 12 January 1945 spoke of evacuating it to Saxony, but by 22 January the last train had gone, and the Red…
Hijacking of Northwest 305 (D. B. Cooper)
The "Washougal washdown" has the bundles washed down the Washougal into the Columbia and deposited on the bar; it requires the money to survive years in water and to pass the 1974 dredging if Palmer's stratigraphy is…
Homo naledi and the Rising Star burial claims
A burial in archaeology is usually recognised by a cut through existing layers, infill that differs from what it cuts, and a body whose position and articulation show it lay in a protected space, all demonstrated in…
US government UAP disclosures
Its question is narrow: what has the US government actually said, under its own name or under oath, about unidentified anomalous phenomena, and what does that record establish. The record has four layers.
Marfa lights
Layers of cold and warm air bend light, lifting distant lights into view and making them shimmer ; the Handbook of Texas calls this the most plausible explanation .
White Shaman Mural
Paint taken from several White Shaman figures under the 2025 protocol, with controls on bare rock and oxalate layers above and below, would either reproduce the legacy values near 2,000 radiocarbon years or replace…
Proto-cuneiform: the archaic texts of Uruk
The tablets come mainly from the Eanna precinct at Uruk, where the German excavations found them from 1928 onwards in rubbish layers and building fill, and from Jemdet Nasr, Umma, Larsa, Tell Uqair and Kish .
Glozel: the inscribed tablets of the Fradin field
The Glozel collection is about 3,000 objects dug from one field and its surroundings between 1924 and 1936, almost all of them by Morlet and Fradin without a recorded stratigraphy .
Etruscan: the readable language that cannot be fully translated
There is a genitive in -s or -l, a locative in -i, a pertinentive in -si or -le used for recipients, and two layers of endings can stack, so that a word for "of the son of X" can be built by adding one genitive to…
