Chris is visiting the Cambrian

Wish I could be there.

It’s a day of writing, of car repair, of trips to the airport (we’re shipping Skatje off to a work camp…shhhh, don’t tell her, she thinks she’s going ‘camping’), and little low level aggravations, like being locked out of my office because they’re waxing the floors. So, sure, I wouldn’t mind a little African geology trip right now.

    I thought the Cambrian happened in Wales…

    And the Ediacaran happened in Australia. History certainly was a bit of a gadabout, wasn’t he?

    Hmmm. Does that then put Ken Ham in the Cincinnatian?

    NJ, Cincinnati boosters will happily tell you that The Hamster is in Kentucky, on the other side of the river.

    That reminds me. Has anyone here been to Mistaken Point, NF? I thought that I saw somewhere that making copies of the fossils is prohibited but saw people doing just that on a tv show but now can’t find that with a Google search. I was also wondering how bad a walk it is. It doesn’t seem bad compared to taking a hike up to the Mt. Stephen Fossil Beds on wet clay but I was a fair bit younger then!

    Just so. But the Upper Ordovician rocks (Cincinnatian series) extend over the river (OK, OK, under the river) into Kentucky.

    Just my way of comparing Ham unfavorably to a trilobite or horn coral.

    Geological time intervals are usually named after locations with rock formations that are notable members of those intervals.

    Which is why Ediacaran-period rocks are also found in several other places.

    What I find interesting is that the Pre-Cambrian beds are limestone – made from the skeletons of millions of dead (multicellular) animal-shells ….

    Did you know that, in Wales, there is a local newspaper called “The Cambrian Times”
    ??

    That site looks really interesting (well, to a non-geologist like me). And Namibia is a lovely country.

    As for African trips…I’m lucky to live about a 25 minute drive from the Sterkfontein Caves where they’ve been removing Little Foot from the rock for several years now. I love visiting the caves.

    Actually, most of the limestone was inorganically precipitated, either directly from ocean water or associated with stromatolites (algal mats).

    And although the Cambrian was originally defined from the sequence in Wales, it turns out that most of the lower Cambrian there has been removed by an erosional uncomformity. It’s not the only time a name has survived long after the type locality has changed.

    I’m not complaining about the link, of course, but I only thought PZ would start getting jealous when he saw the fossils
