Henderson Posted July 20, 2016 Share Posted July 20, 2016 PHOTOS ATTACHED I found this along the shore of Lake Ontario, in the small town of Port Hope, Ontario. The stone itself is about 1 1/2 inch wide but the stem-like print is about 3cm long. The circular print is about 0.5cm in diameter. Some sections even seem to have a bit of a shine to them when the rock is shifted from side to side in the light. Link to comment Share on other sites More sharing options...
ynot Posted July 20, 2016 Share Posted July 20, 2016 Welcome to TFF! Your rock is a piece of limestone with pieces of crinoid stems in it. It has also been stream tumbled. The long one is in cross section. Nice find! Tony Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Fossildude19 Posted July 20, 2016 Share Posted July 20, 2016 Welcome to the Forum. The semicircle is likely a cross section through a valve of a brachiopod.

It was more then likely brought in by the lake. This was the first none shell fossil I have found in this specific location and I'm happy to add it to my small collection Link to comment Share on other sites More sharing options...

BobWill Posted July 21, 2016 Share Posted July 21, 2016 Welcome to the forum. I agree and the semicircle may just be what's left of a complete circle. If so it's probably another column or columnal. I love the way it's preserved, worn through to the center and possibly crystalized. edit: I recently learned that the center of the stem, which is often hollow, had part of the body going down through it. They were much more complex animals than I thought. Link to comment Share on other sites More sharing options...

They were much more complex animals than I thought. I love how it is too and I was honestly thinking about trying to polish it, once I do some research into how to polish stone that is. I think it would look pretty nice shined up And I know next to nothing about fossils and the creatures that made them ha ha But I suppose something in the middle could explain why it's a different colour? I disagree with others, just to balance things out. Thank you for balancing things out ha ha Wish you luck on IDing my future finds first Link to comment Share on other sites More sharing options...
ynot Posted July 21, 2016 Share Posted July 21, 2016 I suppose something in the middle could explain why it's a different colour? In the animal that is a crinoid (sea lily) the soft body parts are surrounded by a hard "shell" and the hole in the center is where the soft parts have rotted out. This area of the animal was filled with sediment before fossilizing. Can You post a picture from the side? I do a lot of lapidary work and this stone maybe unsuitable for polishing. (at the least You would lose a lot of the detail.) Tony Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

fifbrindacier Posted August 5, 2016 Share Posted August 5, 2016 There are little cracks on the side, if you polish that stone you'll lost those parts and a lot of little details that make it an interesting piece. I would left it as it is. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

ynot Posted August 5, 2016 Share Posted August 5, 2016 There are severe cracks in this rock that may fail (come apart) under the stress of grinding to get to a stage to polish. Aside from the cracks in this rock, it looks porus and would not take a good polish. I would leave it as is. It is still a nice fossil! Tony Darwin said: " Man sprang from monkeys."
