Doggerland That IS interesting. I got interrupted when I first read the link, so forgot to go one level deeper (no pun intended)... That's a big bit of land Findings suggest a picture of a land with hills and valleys, large swamps and lakes with major rivers dissecting a convoluted coastline. So we must have been quite high up in them thar days of old! (by that I mean us sea level lot where the waves now threaten to lap at our feet):) Thanks for the post Chris, and the thread! :) I found something about a recently discovered fossil of a flying lizard and couldn't find anywhere to post it. This might be a good place - if I can find it again... :) |

Forgive a slight digression (it's how my brain works - sorry :)) but, were sea levels to ever drop sufficiently, would that mean we'd stop being an island? :) |

Yes. See the linked map of sea level during the last ice age, when more of Earth's water was frozen out of the ocean. http://www.iceagenow.com/Sea_Level_During_Last_Ice_Age.htm |

I know it's unlikely to happen in our lifetime, but... just in case... :) |

Fascinating to see that Britain was joined at two locations, and that the Baltic Sea was a lake, and how much of the coastal outline is all but unrecognisable. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

That is a really nice map WK, many thanks. It shows the Weald–Artois anticline before the English Channel was formed. God knows why Farnham was singled out. I'll have a look into that.

Not sure where to put this, but it's sort of archaeology so am hoping Chris won't mind me plonking it in here :) Shattering past of the 'island of glass': Pantelleria, a little-known island near Sicily, was once covered in a searing-hot layer of green glass "Incandescent rock fragments suspended in the all-enveloping volcanic cloud were so hot, molten and sticky that they simply fused to the landscape forming a layer of glass, over hills and valleys alike. The hot glass then actually started flowing down all the slopes rather like sticky lava. 'Ground zero' in this case was the entire island -- nothing would have survived -- nature had sterilized and completely enamelled the island. |
