What a Big Piece of Sh*t

The Lloyds Bank coprolite is a large coprolite, or fossilised specimen of human faeces, recovered by the York Archaeological Trust while excavating the Viking settlement of Jórvík (present-day York) in northern England.

The coprolite was found in 1972 beneath the site of what was to become the branch of Lloyds Bank on Pavement in York, and may be the largest example of fossilised human faeces (palaeofaeces) ever found, measuring 20 centimetres (8 in) long and 5 centimetres (2 in) wide.

Analysis of the stool has indicated that its producer subsisted largely on meat and bread, despite evidence suggesting that other people at the same place and time had access to fruits, leeks, shellfish, and nuts. The stool had undergone mineralisation, unlike some other human coprolites which are preserved by desiccation. 

The presence of several hundred parasitic eggs suggests the person was riddled with intestinal worms (specifically maw-worms and whipworms).

In 1991, Andrew Jones, a York Archaeological Trust employee and palaeoscatologist, made international news with his appraisal of the item for insurance purposes: "This is the most exciting piece of excrement I've ever seen ... In its own way, it's as irreplaceable as the Crown Jewels".

 The layers that covered the coprolite were moist and peaty. The archaeologists also recovered preserved timber, textiles and leather from the site.
