Did you catch the truly fabulous Time Team Special "Britain's Drowned World" on Channel 4 at the weekend? Don't worry if you didn't because you can watch in online at
It gives a fascinating and detailed picture of the Mesolithic period in Britain and what happened as the climate warmed, the glaciers melted and the land connecting Britain to the continent was inundated. Lots of detail on implements and fossil finds. Specially fascinating was the undersea geomagnetic survey of the north sea which showed the outlines of the major river that was once the Thames and Rhine linked.
Do catch it if you can.
