Tenuous again
Yesterday the Guardian reported about an exhibition in a museum in Leiden NL about DOGGERLAND, a lost country under what is now the North Sea. The connection is that many animal bones, artefacts, tools have been found there.
Doggerland would of course have belonged to the UK, had it not been drowned 8200 years ago.
There is a utube film about the exhibition, in Nederlandse with English subtitles.
Besides, I have been to Doggerland, or rather passed over it while asleep on a cruiseferry.
