JURASSIC SCREWS

Imprints of fossils which have fallen from rock.  (Portland Stone.)

The long triangular ones were probably Portland Screws (Aptyxiella portlandica) - gastropods of the late Jurassic Era.
If so, they lived more than 144 million years ago.

    Oh, this is just a fabulous photo, Lucy. One of your very finest. Just inspires the imagination. And should humble us humans who have not walked here all that long.

    Beautiful photo! I always like finding the little fossils. Back at my country they are easy to spot in the desert

    It gives one a funny feeling, such imprints of once living things. I like the little yin-yang shapes where the shells have been sectioned laterally.

    I'm afraid nothing happened next! The woven thing didn't get much further and looked a bit like some kind of crazy hat.

    That's such an interesting and beautiful shot too. I like the way fossils of all kinds look and they are good subjects for photography.

    Hello Nouvelles Couleurs. I find these fossil remains fascinating too.

    Hermes - these were before us!

    They are fascinating, Mo!

    Hello Jodi - I'm specially pleased you like this photo. There are many fossils along the Dorset coast, constantly being released from the cliffs by the tide. In some ways we become blase - they are so common. On the other hand, one is struck by awe every time one goes for a walk! I was a bit concerned that this picture looked a bit text-bookish for the blog so your comment is specially welcome!

    Fer - it would be amazing to find fossils in the desert. I would guess they are very different from the marine creatures we find here. (?)

    Kitty, these 'Portland Screws' were curly shelled - a bit like modern whelks I would guess.

    Hello Lui - your comment is enigmatic.

    Hello John. I was a little tempted to draw out the abstract nature of this photograph by increasing the contrast - but realised many people may not be familiar with the real things. Now I have put this here, I may heighten the contrast another time.

    Hello Greyscale Territory - the timescale is awe inspiring.

    Hello James. By chance, the shells have been pressed down almost into a wheel shape in one section.

    Hello Dragonstar - there were so many. I imagine they sank to the bottom over time. (That's an assumption.)

    Hello Pat - 'awesome' is accurate.

    Hello Carver. Unfortunately I haven't come across any ichthyosaurs yet. They would be truly fantastic subject matter!

    Thanks Chuck.

    Johnny Nutcase - do you ever show them on your blog?

    Thanks Jidhu Jose too.

    Thanks for your visit, Halina.

    Lucy
