Hello everyone. My daughter found this today on a beach in Alpena. We know it’s a coral, and so far, two folks suspect it is possibly Heliophyllum. I’m unfamiliar with that species and have nothing to compare it to. Just wondering if anyone else has seen something similar?

I bought this from a box of unlabelled stuff that a dealer friend in the UK is gradually going through. Another friend IDd the coral as a Heliophyllum halli, perhaps from Hungry Hollow, which seems a good bet - I'm not very familiar with stuff from there though. Middle Devonian anyway. It was the epifauna that really interested me, especially this nice patch of the bryozoan Botryllopora socialis. (It also has other bryozoans, hederellids and cornulitids.) Scale in mm.

It has become a yearly tradition of mine to visit the upper part of Michigan's lower peninsula, around the Gaylord and Traverse Bay areas, for vacation with my family, and I often spend time looking for fossil in the area, mainly Hexagonaria/Petoskey stones, but for some reason they are far and few between. During my time in the area, I have also found a chunk of limestone containing what appears to be the glabella of a trilobite surrounded by what appears to be large, crystalized corals, possibly a Heliophyllum or similar rugose coral, a smaller piece of the same coral, and what seems to be the calyx and arms of a crinoid. Should I be looking anywhere in particular along the shores of Lake Michigan that aren't as well known as some of the popular tourist destinations? Also, are there any areas more inland that are accessible? (i.e. old quarries, roadcuts, etc.) Any and all advice would be greatly appreciated!

From the album: Arkona material
Rugose coral from Arkona. Middle Devonian, Arkona, Ontario. I've always thought that rugose corals were interesting to look at, so I was excited when I traded for one with a fellow member.© (©)
