What's the most unlikely thing you can imagine archaeologists finding underneath a churchyard in St Pancras?
How about the bones of a walrus?
Glen Goodman explains.
The walrus bones were found at a dig at St Pancras Station.
Archaeologists have been left baffled by the discovery of walrus bones in a coffin under St Pancras Station.
They were found during excavations at the station, before it was refurbished to become the new Eurostar terminal.
Crossrail’s Lead Archaeologist Jay Carver said:
The Crossrail archaeology programme has also unearthed its first Bronze Age finds - although these won't form part of the exhibition.
Two wooden stakes, cut by early London hunters with an axe, and a hammer stone have been discovered at excavations at Plumstead.
Historians believe these may have been used to build a large network of timber pathways across east London, which may have made it easier for hunters to catch animals living in the lush wetlands some 3,500 years ago.
Archaeological finds, discovered at Crossrail worksites across London, are going on show in a special exhibition.
Medieval human bones and a piece of mammoth jaw bone are among the items on display at the Crossrail Tottenham Court Road Visitor Information Centre.
Large-scale excavations are taking part in several places across the capital, as engineers prepare to bore tunnels under the River Thames for the Crossrail train project.
Construction of a multi-million pound leisure centre in Elephant and Castle has been suspended after the discovery of 500 skeletons.
They were in crypts, some of which date back to before the Black Death in the 1300s.
