    Okay. I was thinking of them crewing up complete with paddles. A bit like the PG tip chimps.

    It seems the vikings made their way to the U.K. just by drifting across in the currents.

    The question is whether the life on the natural rafts could have survived salt water long enough to support the primates on their voyage.

    But certainly a very interesting idea plus one has to remember that over those sort of timescales sea level has been up and down like a yoyo and the Atlantic was a wee bit less wide 30 odd million years ago.

    Some species have been known to travel on whole continents. Take India for example. It used to be down by Madagascar. It then split up with Madagascar and travelled north up to dock with Asia, bringing the indigenous species with it.

    Oh indeed :D

    That is much easier to understand ;)

    India was, if I remember, quite a fast migrant, hence the crash and the resultant Himalayas ;) :D

    A major Craton around India one of the thickest I think?

    Polar bears do it on icebergs too.

    People have found shells from marine species up in the mountains of Nepal so the crash was quite powerful. :eek: :D:D

    Same in the Alps, it's stuff like that that creates the body of evidence supporting continental drift.

    The interesting thing is that the earth's crust is thickest in the Himalayas nearly 50 miles thick, compared to something like 6 miles at the floor of the oceans.

    There was a geologist and climber who went to the top of Everest and brought down fossils from the summit. Kenton Cool. Brought down rock samples and took them back to Oxford University. He has climbed it a number of times.

    Coober Pedy, the opal mines.

    That’s where people live under the surface, I gather. The region has colossal shale oil reserves.

    Were those the dark looking round concretions with a fossil on the inside when you break them open? (They are highly sought after from a religious stance).



    Shaligrams as the locals call them. The fossils are ammonites which are or were marine creatures that lived well below the sea surface. Now found half way up in the Himalayas.

    The clash of 6,000 years versus 4.5 billion years. Those ammonites have a lot to answer for. ;)

    They were ammonites, the same fossils as the kids in Pakistan hunza valley sell when they try to flog you garnets as rubies :lol: I met a Filipino geologist years ago who worked for the DENR, I spent a few days with him while he and his team were checking caves, got a pic of him somewhere opening a coffin :ninja:

    Yes. I hadn’t thought of it like that. A bit ironic.

    They appear in the fossil record from 240 to 65 million years ago and died out when the dinosaurs did. Their closest living relative is the Nautilus.
