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.


This post is for The Weekend in Black and White

Fascinating

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.

Lui said...

Hmmm, interesting imprints!

John said...

A 'natural' abstract.

Greyscale Territory said...

Wonderful arty imprint of life that lingers through time!

James said...

Amazing! I love the patterns.

Dragonstar said...

I love the look of fossils - life remembered by stone.

Pat Tillett said...

that is so awesome looking! Nice photo Lucy!

Carver said...

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.

Chuck said...

That is a really cool shot, Lucy. I still say you have a great eye.

classic shot

Johnny Nutcase said...

very cool! There's a place in Texas where I come across rocks like this pretty often, always love seeing them!

Halina said...

Lovely.

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
