I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

From the album: Fossil Collection: DC Area and Beyond
Cnidaria Alpena, MI Rockport Quarry Limestone Middle Devonian -
I went to Rockport quarry in Michigan several times this year. And found this trilobite. A friend says it looks like Crassiproetus but i am not sure.... Thanks! In advance

I first became interested in fossil collecting while living in Michigan, so any fossils I find in the state are somewhat special to me. Last summer I took a quick trip up to Alpena, MI to collect the Devonian in the area. Lots of interesting things were found, including two Eldredgeops. Neither is complete, but I was still quite happy to find bugs in a state that does not give them up easily.

Going through material from last year and found this piece. It looks to be some sort of plates. Roughly 1.5"×1" for full specimen. Larger plates are around 1.25cm in diameter with the smaller ones around 2/3 cm. I don't recognize it. I tried the lick test as I was told bone sticks to your tongue and it does stick. Fish plates have been found in this locality but I have never found anything definitive. Unsure of the formation. It was near the bell shale washout in Rockport quarry where I picked it up. I suspect it came off the hill going west of the creek near the trail.

Thunder Bay Formation- Partridge Point Blastoids
Tales From the Shale posted a topic in Fossil Hunting Trips
Here is a comprehensive list of most of the blastoids personally found by me at PP. This is roughly 80 hours worth of collecting the site from 4 total trips. Placoblastus obovatus: Specimen 2 Specimen 3 Hyperoblastus bassleri: Heteroschisma subtruncatum: Nucleocrinus meloniformis: Specimen 2 Specimen 3 Unknown blastoids: Specimen 2 Going to post one massive topic about Partridge Point tomorrow, still working out how to shrink photos so it isn't a mile long.

Small collection of fossils from the Potter Farm Formation (Alpena, MI)
Cassandra Tiensivu posted a topic in General Fossil Discussion
This is a small sampling of some of the more interesting things to come out of the Potter Farm Formation in Alpena, Michigan via one bucket of screen washed muck. Crinoid pieces: Cystoid segments: Trilobite fragments: A platyceras: Blastoids: Loads of brachiopods: And tentaculites: Not pictured are the over abundance of bryozoans.
-
Here’s one (technically three) from the Potter Farm formation (Alpena, MI) that I really have no idea on. Crinoid, maybe? All three pieces are basically the same. I just set them up at different angles so you could see how they looked from different views. Any thoughts?
-
I collected a bucket of muck from my favorite ditch in Alpena (Michigan), and screen washed it. This is the Potter Farm formation. There have been some very interesting things to come out from it. Most of it I can give a basic ID to, but this one has me perplexed. A friend suggested they might be disarticulated pieces of a cystoid. I have never found cystoids before, so this is completely new territory for me. Does anybody have any thoughts? Front: Back: (Sorry about the pen! I misplaced my ruler. Needed something for scale.)
-
I was told this is pretty big for tentaculites.
-
Sorry I don’t have clearer photos or anything in here for scale. This is freshly pulled from a ditch in Alpena, Michigan and we’re still out in the field. I had no idea Michigan had spiked gastropods. Any help on an ID would be most appreciated.
-
Some finds from our most recent fossil finding expedition to Alpena Michigan. Anyone know species possibly of these two? One with spikes and one without?
-
I collected these spines in Alpena, Mich., Potter Farm Formation, Middle Devonian. I don't know whether these are tegmen spines or stem spines. Nor do I know the genus or species of crinoids that had spines like these. Sharper minds than mine are on the Forum, so I'm hoping someone might have an idea of which crinoid they belonged to.

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?
-
Hey everyone, so I've done quite a few trips to the Rockport quarry in Alpena and a few road cuts around presque isle, but I was wondering if there aren't any "hidden gems" I'm missing out on in the LP.
-
Of the fossils I collected last summer, there was a group of specimens that stood out because of their gray/orange coloration. The photos, unfortunately, don't give you any depth perception, so it's hard to see the curves and grooves. I'm pretty sure it's a sort of solitary coral, but I'm pulling my hair out, searching everywhere to find similar images, but to no avail. These were collected in the same area on Lake Huron this summer. What do you think they are?

Last year i thought I was going to be able to get to Alpena. Michigan while at my daughters in Grand Haven, but I wasn't able to. This year, I will be there for three weeks, and so plan to travel across the state. So... I am wondering if someone would recommend a good area to go. I have looked up a bit about Rockford? and there is apparently an Evergreen cemetary with fossils along an edge, but the sources I found were a couple of years old. I have already had the experience of traveling several hours only to find a new housing development build over the site I wanted to check out...so I am trying to same some time, but find recent locations. In addition to hunting the Lake Shore south of Grand Haven, are there any sites near Grand Rapids to look. I have heard there are fossil banks on the river, but I won't have my kayak along this time, so I need firm ground. I am also hoping I don't have to dust off a layer of snow simply in order to check out the rocks. LOL. Thanks to anyone who helps.

I am on my annual trip to northern wisconsin and the U.P. of michigan, ( the newberry area where I pick up nodules and find trilobites etc. ) This year it looks like I may be able to head over to alpena, and area I know has a great fossil reputation, but I have no idea where to hunt. I really don't have the time to research and ask permission for quarries, so I wondered if anyone knows of some public hunting areas around. I would much appreicate it.
