dagwood Posted September 20, 2020 Share Posted September 20, 2020 (edited) We found the following in Harbor Springs, MI in July. Initially thought it might be petosky, but it’s a lot lighter in color and smaller markings. Thanks in advance!

Tidgy's Dad Posted September 20, 2020 Share Posted September 20, 2020 Could be a favositid coral. or not. Can we see a photo of the side and back, please? 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

TqB Posted September 20, 2020 Share Posted September 20, 2020 (edited) There are many mural pores, and tabulae showing in the longitudinal section, so I agree with @Tidgy's Dad that it's a favositid, with what looks like a lot of recrystallisation that obscures a lot of the detail.
