Tidgy's Dad Posted December 6, 2021 Share Posted December 6, 2021 Not barnacles. A fish mouthplate, perhaps? 4 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

noahc0d Posted December 7, 2021 Author Share Posted December 7, 2021 Yea I think that's probably it, thanks @Tidgy's Dad and @Harry Pristis! Link to comment Share on other sites More sharing options...
minnbuckeye Posted December 7, 2021 Share Posted December 7, 2021 This is likely not a fossil but a mouth plate of a Sheepshead (Drum), common in the waters of Lake Erie. The local geology would not have fish like drum. The teeth have fallen out of your specimen. Plus, there is no wear and tear evident from a fossil tumbling in Erie's waters long term. It is still a keeper though!! Mike 2 Link to comment Share on other sites More sharing options...
digit Posted December 7, 2021 Share Posted December 7, 2021 I'm guessing it would have been fresh water where this was found. The only drum with a pharyngeal plate like this is Aplodinotus grunniens. Take this as a lead to see if it occurs in your area. Wiki says it gets as far north as Hudson Bay so that sounds encouraging. https://en.wikipedia.org/wiki/Freshwater_drum (Likely modern, BTW.)
