They found Mesolithic tool-making factory featuring 150 pieces of flint at the tunneling worksite in Woolwich. Archaeologists said prehistoric Londoners used the site to prepare river cobbles which were then made into flint tools. The lead archaeologist Jay Carver said: "This is a unique and exciting find that reveals evidence of humans returning to England and in particular the Thames Valley after a long hiatus during the Ice Age."
The concentration of flint pieces shows that this was an exceptionally important location for sourcing materials to make tools that were used by early Londoners who lived and hunted on Thames Estuary islands.

Archaeologists have also found a Roman gold coin at the dig in Liverpool Street. They believe the 16th Century gold coin was used as a sequin or pendant, similar to those worn by wealthy aristocrats and royalty.

Dripping beside him on the sand, she touched his arm, a soft expression in her eyes. "What do you think happened in the before times?"
"About making life?"
"No, silly. To the world. To all the others who wrote books and built splendid dwellings and halls. Like ours."
"Some folks in Hailing say Corn World rose after a huge rock fell from the sky and shattered the land."
She peered up. "You mean when a star falls with a trail of light behind?"
"I guess so. I often see them. None has hit anywhere near me."
"Did that cause the flood?"
"Could have." Pleased at a chance to share his opinion, he took a deep breath. "How can we know? Anyone who lived through what happened isn't here now. Just us."
"Is the land flooded everywhere else?"
"I don't know. I've never left Corn World."
