    BBC News - Earliest Footprints Outside Africa Discovered In Norfolk

    Link: BBC News - Earliest footprints outside Africa discovered in Norfolk



    ...The footprints on Happisburgh beach are possibly those of a family in search of food...
    ...The sea has now washed away the prints - but not before they were recorded

    If those people were alive today, they probably wouldn't notice a lot of difference.

    How.. exactly? How could they have survived > 800,000 years, only to be coincidentally washed away the moment they are found?
    The cynic in me is sceptical of this.

    It's pretty simple really, they'll have been full of compressed sediment or something for the thousands of years and only spotted due to the discolouration during excavation, and now they've removed that blockage in order to examine them, the tide will have washed over and worn away the indendations which have been protected for thousands of years.

    I'm sure I saw something similar on Time Team not so long ago.

    I read it this way: The recent storms moved the layers of sand that had protected the impressions for so many years. More storms caused erosion of the soft rock where the impressions had been preserved.

    I thought the exact same thing. The sea has been erroding the coast quiet badly in that area for years, how come they weren't washed away at any other point in the past 800,000 years? And how did they date the foot prints? Beeb suggests they didn't have a lot of time before the sea reclaimed them.

    This is Happisburgh beach ( for those of you who are not local it is pronounced Hays-borough ) the area is under threat from coastal erosion and was hit very badly in the November spring tides/storm surge. It is likely they were uncovered then.

    Hm. Could be.
    I wouldn't expect the rock underneath to be so soft, though.

    Comparatively soft or a compressed sediment or something like clay perhaps.

    Other than how to make a teacher a reasonable person to work with (and yes I am tarring with the same brush/blanketing/saying with tongue firmly in cheek!) is there anything the EduGeek community doesn't know?

    We don't do rock in e-Stanglia; mostly it is un-consolidated glacial material (it is not stuck tightly together) is very easily eroded hence the rapid rate of retreat of the coastline of this region.

    I've fished the coast here for many years and every time I go there's another bit missing!

    Something about the slow pace of life round here makes geological time just fly past
