@chad-bruce That’s alright! Thanks for getting back to us! Dimensions of the specimen, if possible!

Hi, @mackenzie-ross-2 and @Chad-Bruce! I think photos of other sides of the fossil would be useful here, but I do see how this could be a trilobite pygidum (butt).

Hi there, @chad-bruce do you have a more specific location of where this was found? I believe that the age can (hesitantly) be identified as Ordovician. If you could also fill in the dimensions box that helps make it a research-grade specimen! @samantha-ocon may be able to help identify your possible trilobite!

Thanks for tagging me in @sadie-mills. @chad-bruce – this looks like several different species of brachiopod shells that have been worn down. The Fossil Guy has a good page on Devonian brachs of NY (similar species to MI): https://www.fossilguy.com/sites/18mile/18_col.htm you should see some similar shapes!

@chad-bruce another awesome find! I see that you’ve already got some of the information filled out! @david-clark might be able to help you narrow it down further. In the meanwhile, to make this research grade, you can upload photos of it against a neutral background with a scale for reference!

Hi there @chad-bruce, from these pictures, this looks like it might be a chip in the rock! If you could upload these with the specimen against a neutral background and with a scale for reference, we might be able to ID it!

Hi @chad-bruce, cool find! If you could upload this against a neutral background with a scale for reference, that might be able to help narrow down the ID even further, and even make this specimen research grade!

@chad-bruce@samantha-ocon Thank you 👍👍

I agree with @Chad-Bruce, @Amy-Wu, I believe this is a horn coral.

Awesome find, @chad-bruce! I agree with @matthew-gramling, I see some crinoid stems and I think the jagged pieces may be strange sections of brachiopods – there is a really diverse Middle Devonian fauna in Michigan!

Hey! @chad-bruce ! I think I see some Crinoid stem segments.

Hey @dawn-vitale ! I concur with @chad-bruce .
