Alexthefossilfinder Posted February 28, 2023 Share Posted February 28, 2023 The top picture here is of something I found. It's very small, barely measuring a quarter of an inch wide, and I can't find much on what it could be. I originally thought it may be a graptolite, but I can't find any genera that match its shape. It's similar in shape to a marrellomorph, such as the Furca in the second image, but I haven't found anything conclusive, especially being that Marrellomorph fossils are extremely rare. 2 more things: I found this when I was young so I don't know where it came from, but it most likely ranges from Ordovician to Devonian based on where I've been. Unfortunately I can't get any better pictures as I got this from using a magnifier at the ROM, but as of now I do not have one of my own that I can use to zoom in any closer.

FossilDAWG Posted February 28, 2023 Share Posted February 28, 2023 Sorry, but I do not see it. However the photo is very pixelated which might be obscuring the image. Don 1 Link to comment Share on other sites More sharing options...

Kane Posted March 1, 2023 Share Posted March 1, 2023 Judging by the other “branching” features on the rock alongside the crinoidal bits, it seems probable that the tiny specimen is a sheared cross section of bryozoan. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Along which axis do you think it would be? I don't know much about bryozoans Link to comment Share on other sites More sharing options...

The only doubt I have on that is the shaping. I can see it if it's just a circular shape, but its also got the part sticking out on the right side, which I imagine was mirrored in life Link to comment Share on other sites More sharing options...
FossilDAWG Posted March 1, 2023 Share Posted March 1, 2023 It could be a section through several very different things, such as a brachiopod, bit of a trilobite, etc. A closer photo with the fossil centered in the field of view would be helpful. That being said, I doubt very much that it is a marrellomorph. Marrellomorphs are always highly flattened, it would be extremely unlikely to see a section through one in a limestone cobble like this.
