Hello, everyone, I could use some help with this odd little tabulate coral I found yesterday in an old gravel pit in southwest Michigan. I can't guess at a formation or age since it's glacial debris, but the things I find range from possible Ordovician (rarely) all the way to lower Mississippian. I think it must be either Devonian or lower Carboniferous. When I first picked it up, I thought it was just another type of Favosites, given the corallite shapes and what turned out to be large mural pores (towards the left) when enlarged: (EDIT: TqB has suggested parasite traces for these holes I was calling 'mural pores!') But on the other end, the corallites are showing what I thought were curved, incomplete tabulae like Michelinia, but found out after talking with @TqB that they may be funnel-shaped. I forgot to include a size scale, but the corallite diameters range from about 2 mm to just under 4 mm. We're having trouble coming up with cerioid infundibuliform tabulate corals that might be possible for Michigan, and Tarquin suggested that the coral experts here might have some ideas. Many thanks! Lisa
