I found this in the sand right at the water of the Warren Dunes State Park beach. Maybe hard to tell from the photos, but there are definitely pores where the tooth would have broken off. There’s also a ridge that I am guessing shows where the tooth would have emerged from the gum line. I didn’t set that ruler up very well. It is just over a half an inch or 1.5cm long. From the ridge to the tip is about a 1/4 inch. And the width of the base is just over a 1/4 inch. My apologies if this is just some dog tooth or something from the last decade or so.

Found this, and a ton more, with my daughter over the years. Found this on Lake Michigan, near South Haven - Coldwater Shale Formation/Mississippian/Devonian There are lots of braciopods, from what I can see. Some having an amber looking coating, others having a metallic coating. Can anyone help with this, before I start to polish it (and let me know if I shouldn't). I've always just picked up rocks and coral fossils at the beach, and just now have really started to get curious....so I'm new to this, forgive me if I've missed anything. There are some close up shots, with a tootsie roll for scale...only thing I could find lol.

Hexagonaria Coral 'Petoskey Stone' (Polished) Michigan Devonian period (~350 million years ago) Hexagonaria is a genus of colonial rugose coral. Fossils are found in rock formations dating to the Devonian period, about 350 million years ago. Specimens of Hexagonaria can be found in most of the rock formations of the Traverse Group in Michigan. Fossils of this genus form Petoskey stones, the state stone of Michigan. Hexagonaria is a common constituent of the coral reefs exposed in Devonian Fossil Gorge below the Coralville Lake spillway and in many exposures of the Coralville Formation in the vicinity of Coralville, Iowa. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: Stauriida Family: Disphyllidae Subfamily: Hexagonariinae Genus: †Hexagonaria -
A total newbie here looking for an ID. Thoughts?

So I was on a hunt for Patoskeys over on lake Huron and I came across this very odd find. It looks to have the exact qualities of an egg. I have been searching around to find others like it and have come up empty. Any help?

UPDATE: This specimen has been identified by Steve LoDuca as Thalassocystis striata, a non-calcareous Silurian macroalga. Interestingly, the type specimen was found in the same general locality as my specimen. I have a friend who works in a Silurian dolomite quarry in Mich. He sent me this pic this evening. I have not examined the rock in person yet. The pessimist in me says mineral deposits. The optimist in me says maybe fossil algae. It's a long shot considering dolomitized limestone... but it sure looks interesting... thoughts?

Found what might be a tooth fossilized in the Upper Michigan area at Lake Superior.

Hi!
-
I found this a few years ago at my camp near Munising, MI. I find a lot of fossilized corals, trilobites, and bryozoan there. I am going through my fossils and trying to label them, and I noticed this odd one. I am thinking it is a crinoid or a sea pen, but I am not sure.

I found this as a kid in an old surface mine (I was told) in the upper peninsula of Michigan near lake Gogebic. I found it in a large pile of loose sand. It looks and feels like sandstone, but maybe harder. It has what looks like a "foot" on the bottom and a hinge in back. I would appreciate any speculation on what it is. Just a funny shaped rock? Thanks.

Hello, members! I'm from central Michigan and I enjoy hunting for Coral, Brachiopods, Crinoids and gastropods from the Devonian Period! I would look for them at the reservoir of my local park with my sister. It is amazing to collect the remains of creatures from the great past of Michigan! I also enjoy collecting plant fossils, vertebrate and insect fossils. In the past, I would come to this site to get help at identifying the specimens that I've found. I would learn about new forms of fossils by browsing the collections list, and yet I've decided to join this forum to get more help and to make new connections on my favorite hobby. I am looking forward to learning with you all and thank you for Welcoming me in!

Hello all! Thanks again for all of the great info on my Previous fossil! I AM ASTONISHED by how old my coral is! I have another fossil (hopefully) I am somewhat weary about.. its a small piece but to me I believe its a piece of petrified wood. Your thoughts? Once again I am eager to see if I am able to see how old this little guy is. You guys ROCK!

Hello all! I am somewhat new to this but very excited! I recently went on a hiking trip and found this rock (with some fossils) on it. Have no clue what they are; maybe you can help identify them! We were in Free Soil Michigan on the Lake Michigan shoreline when I came across the rock. Any and all help would be amazing! Thanks!!

Some more coral from Lake Huron. Same genus as the Hexagonaria, or a different genus? I found two different individuals. I've got pictures of them both.
-
I found this rock at a beach at Lake Huron. It has a net-like covering. Is this actually a fossil?
-
A pretty neat little fossil from the coast of Lake Huron, Michigan. Two individuals, one on each side. Possibly Mesozoic in age.
-
I found this while looking for fossils off the coast of Lake Huron. A local Geologist said that some of his friends had found dinosaur teeth in that area, so maybe Mesozoic in age?
-
@ynot et al. How would you characterize this rock? It's about 2 lbs and has dimensions of 4-1/8" x 2-1/2" x 3". Heavy, but does not attract to magnet. I am calling it an "iron-rich concretion". From glacial deposits in Michigan. Thoughts?

Hexagonaria percarinata Coral SITE LOCATION: Michigan TIME PERIOD: Devonian Period (359-419 million years ago) Data: A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral, Hexagonaria percarinata. Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges and depositing them in the northwestern (and some in the northeastern) portion of Michigan's lower peninsula. In those same areas of Michigan, complete fossilized coral colony heads can be found in the source rocks for the Petoskey stones. Petoskey stones are found in the Gravel Point Formation of the Traverse Group. They are fragments of a coral reef that was originally deposited during the Devonian period. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: †Stauriida Family: †Disphyllidae Genus: †Hexagonaria Species: †percarinata -
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.

Hello all! I came upon this site while trying to determine whether a certain fossil I have is a coral or a sponge and was captured by the message boards here! I've been a casual collector since very early youth. I LOVE to dig my own finds but have been known to purchase a few every now and then. Most of my finds are from the West Clermont County area of Ohio (outside of Cincinnati), but I used to wander the Midwest region always with an eye to the ground. Thanks for having this site! I look forward to digging through the posts!
