lizwfc Posted April 24, 2020 Share Posted April 24, 2020 Hi all. I picked this up on a dog walk yesterday by Chesil Beach in Weymouth UK. I regularly see belemnites, amonites, sea urchins etc but don’t recognise this. I don’t even know if it is a fossil or a bone or piece of coral. It certainly doesn’t feel like bone. It’s more of a stone / pumice consistency. Can anyone help me identify it please? Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted April 24, 2020 Share Posted April 24, 2020 Possibly a barnacle? but I am not very familiar with their anatomy, so wait for more folks to chime in. 8 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 24, 2020 Share Posted April 24, 2020 I was thinking sponge, but the spongocoel doesn't look right...... Hmmm. Hello, and a very warm welcome to TFF from Morocco. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Hello, and a very warm welcome to TFF from Morocco. I also think this is a sponge. In the second photo we see the Spongocoele or Atrium. That side of the sponge seems to have been broken. The Osculum might be at the other side ? @lizwfc, could you take a pic from the othe end of it ? And welcome from France. 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Al Dente Posted April 24, 2020 Share Posted April 24, 2020 It’s a modern barnacle, maybe Tetraclita. Here are some images from the web. 11 Link to comment Share on other sites More sharing options...
fifbrindacier Posted April 24, 2020 Share Posted April 24, 2020 Ah that's what it looked so strange. I didn't know barnacles like that existed. 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

So not a fossil at all then! We’re rather spoilt for fossils here so I can’t complain. Thank you all so much for your help. Hopefully next time it will be a more exciting find. My favourite so far was a lovely sea urchin which I found on Chesil Beach. I will post a photo for you to see in a minute. Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted April 25, 2020 Share Posted April 25, 2020 Nice find. Micraster, I think, from the flint beds of the Upper Cretaceous chalk, eroded and washed up on the beach. Have some very similar myself. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Coco Posted April 25, 2020 Share Posted April 25, 2020 Micraster with ambulacra so hollow ?

Coco Normally the ones I pick up here are a pale sandy yellow, very fragile and not much bigger than thumbnail size. They seem light so probably hollow. This one is far bigger, much more stone-like and solid. I was throwing stones at a bigger stone on the pebble beach one day. I picked this one up and was about to launch it when I realised it wasn’t a stone at all. I felt so lucky! 1 Link to comment Share on other sites More sharing options...
