Pet wood? Found outside of a fast food place in Wisconsin. Most rocks here are older than trees but this was in a gravel pit.

I'll be straightforward and say I don't know all of the exact rules of a post, so I hope I'm doing this right. I'm Jonah, an undergrad at the University of Oshkosh up in Wisconsin. I've been fossil hunting since 2020 but have loved prehistory all of my life. I'm looking for new contacts and to hopefully network on this site. I live in Wisconsin and have had poor success in my home state. However I have been across multiple other states from Florida to South Dakota, all with much better success. My purpose here is to seek community and new possible places to explore and hunt from. I'm always ready to learn and divulge my own information when I can.

Found a couple neat things in some bags of rocks from Home Depot
LeapingLaelaps posted a topic in Fossil ID
Hello! I got a few bags of rocks from Home Depot the other week to use for a project, and when I was washing them off I found a couple neat things. Unfortunately the bags were thrown away and the garbage was picked up yesterday so I can't check the bags for the quarry locations, but the bags were purchased in Wisconsin so I would reckon the rocks are from either Wisconsin, Minnesota or Illinois. Here are both next to a tape measure. I'm pretty sure the left one is some kind of brachiopod but I have no idea what the striped one is or if it's even a fossil: And a few different angles of the striped one: Sorry for the obnoxious shadow in front, I was using my flash because it was too dark in the house and since I was so close to the fossil my camera left a shadow.

My son found, what looks to us to be, a backbone in the rock, in the shallow water of a beach in Door County, WI. The first picture is the fossil in question, the others are other things we found interesting but less convinced they are fossils. I would estimate it to be about 15 to 18 inches in length. Any idea what it could be? Thanks in advance for your time.

I’m not sure if this is fossilized or not, but I was hoping I might be able to find more info on it here!
-
Newer to fossils. Been searching the same location for awhile now and it's the first time coming across one like this. Just seems so interesting to me. Maybe it's just a rock? Idk any help is appreciated.

7th International Conference on Trilobites & Their Relatives
connorp posted a topic in General Fossil Discussion
Registration has opened from the 7th International Conference on Trilobites & Their Relatives in Cincinnati, Ohio. This is a four day conference (including a mid-conference field trip), plus pre- and post-conference field trips. The pre-conference field trip is to the Upper Cambrian of Wisconsin, and the post-conference field trip is to the Ordovician-Devonian of New York. The latter looks like it will visit some very enticing spots (unfortunately it is quite expensive!). The mid-conference field trip will visit several classic Cincinnatian sites, including possibly the famous Mt. Orab Trilobite Farm. I registered for the conference and hopefully can spend a few extra days collecting the Cincinnatian. Hopefully I'll see some of you there! https://www.cincymuseum.org/7th-international-conference-on-trilobites-and-their-relatives/-

Does anyone have experience with the Middle Ordovician brachiopod faunas of the upper Mississippi Valley? I came across this odd fragment in rocks from a quarry in south-central Wisconsin. To my knowledge they are known in North America only from the Appalachian Basin (Tennessee, Virginia, West Virginia, Pennsylvania, Quebec, Newfoundland), not the interior basins like the Illinois basin. Has anybody else seen this critter or similar in the Platteville? As far as I am aware, the only species documented from the Platteville that looks anything like this is Megamyonia unicostata, but that has a single costa rather than the several apparent here and in the types of Ptychoglyptus. Platteville Fm, probably in P. undatus biozone = Upper Ordovician, Sandbian stage (old North American Turinian Stage)

Posting this for someone on Facebook - found near the Mississippi River, SW Wisconsin. Lycopod root?

Last week we took a ride to Lake Michigan to do a short search before the weather turned bad. The previous day had strong winds with large waves and I thought we might find some interesting things. We found plenty of Favosites, Halysites, and Rugose corrals as well as some of the other usual finds. The one unusual find was what I believe to be an internal mold of a Pentamerus oblongus brachiopod. I don't find many brachiopods and as such I'm not 100% sure on my ID. Please confirm or correct. Thanks in advance. Jim

Hello! I have been lurking on this Forum for a while because I was very busy lately and still is! I found few fossils and I thought it might be trilobits- pieces of trilobite and also something else that I thought it seems 'fishy' and somewhat resemble a fish spine. These fossils are not found in situ but the bedrocks are Silurian. If they are trilobites, it would be my first time found one! I found this on the beach of Lake Erie, just east of Toledo, Ohio two weeks ago. Approximately half centimeter. Yesterday, I found this fossil on the beach of Lake Michigan in Kenosha, Wisconsin - just north of Illinois state line. It looks like a cross section of a trilobite to me. Approximately a centimeter and half wide. Unknown and resembles a fish spine, approximately two centimeters long. Thank you in advance and I am looking forward to seeing the responses!

New to this group and new to fossil hunting. 2 weeks ago was in Florida with the family and found 62 shark teeth along the beach and started to research what they where. Stumbled upon this website and was hooked reading and looking at what all is out there. Hope to learn a lot going forward!

I recently found a piece of petrified wood that has amber bubbling on the top and embedded into the piece. I found it in a region where people have told me there is no petrified wood. I know that it is. I have seen quite a few pieces of petrified wood from Arkansas and a few with amber embedded. This was found in Wisconsin in the Mississippi river valley. Any thoughts?

Hey all! I took my little brother out fossil hunting on the lakeshore, I myself am no expert but it's been a lot of fun- we found a number of crinoid and brachiopod fossils and some cool rocks besides. Theres a couple that stumped us though, I've been googling references but nothing looks similar to me. It looked to me like some kind of coral, the second one might just be a rock with some holes in it, but they appear in a fairly regular pattern that intrigued me. Any input is appreciated!

Found this near a lake in polk county Wisconsin. There seems to be a somewhat unusual pattern on it. Can anybody identify this? I can get more photos and dimensions if needed. Thanks a bunch!

Hello everyone! I recently purchased two fossils, they were both sold to me as Ordovician the crinoid being from Wisconsin and the brachiopod from Illinois. @connorp has told me in a different thread that the dolomites of the region also preserve Silurian fossils and that these look much more like that. Doing a quick Google search I did find something that looks very similar to the crinoid I have, but I don't know enough about these animals or the area they come from to be certain of the ID. Here is the crinoid in question: To me this calyx looked quite similar to that of siphonocrinus both in the gener shape and the plates covering it's surface. Here are some pictures I found online with the region that looked especially similar circled in red: Along with it I also bought this Pentamerid brachiopod which could very likely also be Silurian. Could it belong to the genus Pentamerus?

I am new to this forum and have very little knowledge of fossils. I would like to know if this rock that I found several years ago in northwest Wisconsin is a fossil or just an interesting rock. Thank you.
-
A while back I found this fossil in Wisconsin, unfortunately I don't remember where exactly I was when I found it. So far I have been unable to easily identify it. It is about 2 inches across, and about an inch tall. I can post more pictures if needed.

My collection of some really cool fossils on the land most of the fossils I have in my collection are bought so it’s always nice to find something actually in the field. Now my main goal with this post is to try to identify the trilobite I found today although it only has the head piece, it clearly shows the eye and part of the gabella. The horn coral which are the sort of conical fossils should help identify the age of the rocks. if anyone else can give an ID on the rest of the fossils that would help thanks. By the way these were all found in Dane County, Wisconsin. (PS) I have no clue what the fossil is with the weird holes.

*Higher resolution and many more images linked below to Google Drive for a clear view* Fossil: Large limestone rock containing hundreds of marine fossils and with what appears to be a bone roughly 3cm in diameter. As well what appears to be the remains of other bone structures. Location: Found 10 miles from the Mississippi River near Ellsworth, Wisconsin USA (Western Wisconsin) in a low valley area that looks like an ancient river bed. Rock Measurements: Roughly 15cm x 28cm My Understanding of Geology and Paleontology: 2/10 *There are a vast amount of images so I'd uploaded them to Google Drive in high resolution here: https://drive.google.com/folderview?id=1-QkitLR3bwWFEn0Dh6OoNngsH8F5O31w I found this large limestone rock on our property near what I imagine would be an ancient riverway located at the bottom of a recharge point (aka hill). During heavy rains this area can literally turn in to a river and wash the soil down stream. This rock appears to contain all of the common marine fossils you'd find in Western Wisconsin from what I've researched. However, there's what appears to be a bone or unusual looking aquatic creature near the snail as shown. The snail was extremely well preserved before the vinegar soaking ate the shell and pigment away. A bit more about the location in which it was found; I had been landscaping the slope of the soil for about 2 years in the backyard by shovel. I had lived in this home for about 4 years and I found the soil to be unusual versus any other home I've lived in nearby. The heavy, wet clay soil contained many large green basalt rocks - I'd never seen one before this time. The bedrock is limestone but about 100 FT away the bedrock is sandstone (according to geological maps). The Mississippi river is 10 miles from this location in western Wisconsin near Minnesota. It's also in the path of the "Great Midcontinent Rift" which I find interesting. There are also many large "bluffs" and rolling hills. It's a beautiful area. Anyhow, I'd like to find out what else may be in this rock. It has been in vinegar for about 2-years and is slowly changing shape which in my imagination resembles a skull. I'd like to find a means to protect the exposed fossils while the limestone is absorbing. I had read something about fossil glue or plaster that can protect the exposed fossils while in the acetic acid. This is an educational experiment for me and I've always wanted to learn about paleontology and geology. Any help and identification would be appreciated! There are so many fossils and things to look at in this rock that I uploaded the images to a public folder on Google Drive so that others can view them in a higher resolution. My Galaxy Note 8 is not the best at focusing on close up images so please forgive my photography. If you see something interesting I'd be curious to know! Thanks! -Jack from Western Wisconsin (Google Drive images: https://drive.google.com/folderview?id=1-QkitLR3bwWFEn0Dh6OoNngsH8F5O31w)

A couple more Platteville Formation Grant Co. Wisconsin Trilobite and some others
SteveRogers posted a topic in Fossil ID
Hello, I had some time to look at a few more of the rocks from my collection trip into Wisconsin Platteville Grant County 1,2,3 First is a flat creek rock I gave a scrub and I think it has a trilobite cephalon. 4,5,Is a rock that appears to have a trilobites or it coiled be a broken bivalve? It's in a flakey rock so I haven't picked at it much. I included a side picture of the sediments. 6,7 I am pretty sure these are Chondrites? Or something similar? There are also some other bits in it 8 is a bit of hash plate but it has what I assume must be pyrite bits that are a bit flashy golden - hard to see in the pic but there ar little bit popping out and reflective - I figured I before I show my daughter I figured I should confirm they are pyrite or something similar - and not what she will immediately think it is! Thanks and I hope you all have a wonderful weekend! I'll keep sorting and seeing what I got and maybe walk a creek or two for fun
