This unknown fossil is one of two I found in my teens rummaging around in an old quarry after a blast & they'd gone home for the night. (I know, health & safety would have a heart attack these days!) I'd have a quick sweep through before they all got put through the crusher the following day.
While I wasn't entirely sure of the geological veins of those rocks given my youth, but I had found other bivalves and corals dating from between the Silurian to Devonian periods in the same rocks surrounding. The odd Cambrian thing would show up intermittently but I think that was just other older blast piles underneath.
I've never known what they are but they've always fascinated me. They remind me of corals potentially, especially with the stems, apparently porus skins, shape etc. One has quite pretty "rings" in its centre. The other looks broken in half & you can see inside the inner tubing with odd delicate looking apparatus at the top of each tube. Could be something or nothing, I'll let you experts finally identify what these are 🙂
Photos attached of #2 of the 2 items. I'll attach the second in another post so they are clearly separated.
Thanks everyone who has a gander!
