Found in Maine glacial drift. Most likely Pragian - Emsian aged. Bivalve ? Anything distinctive enough to say more ?

Excited to be here. Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Been lurking here for a couple of years, learning everything I can. Finally decided to join. Always loved fossils, but never had access to many. That changed a couple of years ago, when I unknowingly purchased some very unique land. The age of fossils I find on my property range from Ordovician era to more “modern” times. Have found Chain Coral, Favosites and Horn Coral previously. Plus a few other marine, plant, bone and tooth specimens. There are many moraines in the area, some smaller ones are on the land I have. It is located on the South Western edge of the Green Bay Lobe of the Glacier, during the furthest advance, about 18,000 years ago. Some of the fossils are attributed to when the glacier advanced through the Niagara Escarpment. As the glacier melted, escarpment debris was deposited. The Niagara Escarpment is located from Wisconsin, into Canada and includes Niagara Falls in New York. Yes, some here may know this, but others maybe not. Many of the fossils/rocks on my land are the same as all others near the other Niagara Escarpment locations. Glacial Lake Oshkosh also covered the land. Glacial Lake Wisconsin was located on the very edge of the land, when it and Lake Oshkosh were one entity. Lake Wisconsin contained volcanic debris from the Miladore Volcanic Range, which is located less than an hour from where I live. 6 months after purchasing the land, I rented the 15 acres of fields. They were plowed for the first time in modern history. Had been used for hay prior. In the spring/summer, I spend hours walking the fields. Due to limited vision, I often do not know what I have until I wash it and photograph. Rely mostly on shape, color and any other distinctive characteristics I can make out. My first find was an accident, while riding ATV along edge of fields to pick berries. Contacted a local relative, who referred me to the local college Geology Department. The Department Chair., put me in contact with the local Natural History Museum Director and the local fossil/artifact/rock expert. They have provided the initial ID’s for some of my finds. Fields will be plowed again in the Spring and I am excited to see what else surfaces. Hoping to learn everything I can here. Appreciate the knowledge of members. Will try not to use regional names for my finds I post, but list as unknown (common name) until someone can provide the scientific name. In the process of cataloging and storing all finds with names. Also have some I think are worth further processing, so am excited to learn how to do that. Would love to connect with others in the Upper Midwest USA. Sorry so long, but wanted to share Thank you.

Found in glacial drift in north western Maine. The rock type is a good match for Tarratine sandstone. Lower Devonian marine delta deposits. I've walked by this fossil so many times it's like an old friend. I had always assumed it to be a bivalve with weathered out pyrite crystals. It was exposed on a small gravel beach as I skied by this morning so I decided to give it a look. I think I have been wrong. What do you think ?

Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Is this a Straparollous? Holopea pyrene? Left some slightly blurry photos in to show cm size. The part in question is about .4 cm deep by 1.5 cm wide. There is also what might be a bivalve to the right of it, and maybe, chain coral. Dunno about what is shown on reverse. Looking for potential ID on all and anything else someone might see. Wondering if I should give this a toilet bowl cleaner (diluted) bath? The “snail” appears to be a quartz replacement. I did initial cleaning in Biz detergent for about 24 hours, repeatedly and several days in Oxyclean. Brushed after each soak with polyester bristle brush. Did not want to destroy the crystals above specimens, so avoided wire brush. Please let me know what you think. I also want to be sure I am using correct tags here. Since my land contains Ordovician onward period, should I just list Ordovician as the period? Also, how many tags are appropriate? Should they just be location found and potential period, or should they contain generic terms such as snail? If anyone else here is using an IPhone SE for photos and knows some ways to set it, I would be appreciative. I have been unable to figure out how to change the settings for photographing specimens. The camera has a mind of it’s own, and focuses on whatever it wants, even though I am doing everything that my provider told me to do to change the settings for macro. She said phone is capable of it, but required my digging into the depths, which I did. When I transfer photos from phone to computer they come up at 72 DPI. I am using Photoshop elements to change resolution and size, which usually causes photos to be blurry. Upon transfer, I have photos that are about 40 Meg. Once I adjust the size, they are down to less than 2 Meg. Then adjust focus and color cast to be as realistic as possible. I have figured out the best time of day for taking photos with my portable photo tent, LED light and natural light through patio doors. Also made a stable phone holder to help prevent blurry photos. Thinking there has to be an easier way, as each photo I post takes about 5-10 minutes total. Sorry, obsessive compulsive newbie here, lol. Thanks for looking and any comments appreciated.

This fossil was dug up fishing recently in Kankakee County, Illinois, where the bedrock is Silurian, but this fossil would have to be Pleistocene. Any help with ID is appreciated. I do not have possession so these are the only photos I have. If you provide an ID, please provide your reasoning. Thanks!

Seemed like a good time to get this up. It was found in Little Brassua lake in north western Maine (low water, shallow lake). It is from glacial material that is most likely lower Devonian marine sediments.

Is this a burrow ? I'm sort of leaning toward it being a fluid or gas venting feature myself. It was found on the shore of Moosehead Lake just south of where the fossiliferous, upper Silurian, Forks turbidite crosses it. The breaks are likely caused by the thrust of ice as it forms and expands against the shoreline in that spot. Car sized boulders can be displaced several feet by the force. The blue line indicates roughly the position of the hole. It passes all the way through, with a slight bend and constriction in the center.

Another shoreline glacial find. Most likely lower Devonian marine delta related. The first shot shows part with scale, and inverted counterpart to the left. The last shot is of the under side of the fractured section in the photo before it.

The low angle of sunlight on lakeshore glacial material made this pygidium an easy find, but what is the other thing with it ? The likely age is Pragian- Emsian. One more.

From lake shore glacial deposits adjacent to the Hurricane Mt. formation. Terms like altered and dynamic are used to describe the formation, but the sponge Diagoniella was used to date the deposits. Could this be an example ?

I've had poor luck with sponge posts in the past. Have I at least got these right ? They are from north eastern Maine. The rocks are likely Silurian/Devonian in age.

First trip of the year. Top rim of the gravel pit. Things here are typically lower Devonian and below. Most of it is marine, but plant fossils are found north of here. The closest I come to recognizing the matrix is the volcanic (ash) west side of the Lobster Lake formation.

Long shot, but the texture might mean something.

This was found loose in a gravel bank.

Is this one more recognizable ? It occurred to me that a lot of people may not know what the real structure of these is. Figured it wouldn't hurt to make sure I'm not one of them

Hi all, This is more of a geology question but the attached item is sandstone. I don't think sandstone is known for fossils-us it? Anyway the attached lines in the stone intrigue me. I was told these may be from a glacier. Someone said a plow but where it was found was never plowed but on a Native American site. Anyway , are these grooved fossils, glacial or man made such as abrading?

I was hammering a large chunk of limestone when this popped out. I dug the original rock out of the ground in southern Macon County, IL. From all of the ISGS information that I've read, I know this particular location lies atop the Shelbyville Moraine. I hope that's enough information for everyone. Thanks, Matt

I looks real, but you can't start a camp fire with this. The species is unknown, but I like to imagine perfect pigmentary replacement.
