Port Huron, Michigan trip
SilurianSalamander posted a topic in Fossil Hunting TripsI drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix
2 more Halysites 'chain coral' from Silurian in Wisconsin, acid treatment
traveltip1 posted a topic in Fossil Hunting TripsHere are 2 more Halysites 'chain coral' that I found in the Silurian of Wisconsin. The rocks were soaked in diluted muriatic acid for several hours, to partially dissolve the matrix and reveal the chain corals.
Halysites 'chain coral' from Silurian in Wisconsin, acid treatment
traveltip1 posted a topic in Fossil Hunting TripsI found this rock containing a Halysites 'chain coral' in the Silurian of Wisconsin. I soaked it in diluted muriatic acid for a few hours to partially dissolve the matrix and reveal the silicified coral fossil. Photos are before and after acid treatment.
Halysites (?) specimen

I'm interested in whether it's possible to narrow the ID down between a Halysites species or another genus, like Quepora. My simplistic understanding is that coenenchymal tubules would indicate a Halysites species, so that's what I've been focusing on, although I know there are many other indicators, like size and shape of corallites. size of ranks, shape of luminae, structure of longitudinal tabulae, etc. This piece is probably too silicified to tell without thin sections, anyway, but I thought I'
SE MN Lovely Fall TFF Hunt!
Bev posted a topic in Fossil Hunting Trips@Raggedy Man and his "phantom" wife, Laura, came up to fossil hunt for her 31st Birthday and what a hunt it was! I was busy the first day they were here with my little Airbnb Whispering Winds checking people in and out but they had a wonderful day hunting and Paul found a Bumastis trilobite - they are trilobite hunters. He will have to post his pictures. :-) On Saturday I had invited new fossil friend, Todd, from the Twin Cities to hunt with us. He had come on a paid hunt earlier (he left with 2 5 gallon pails of fossils that very long fossil hunting day) and we had bonded and this was a
