  1. Found on Lake Huron MI beach

    A total newbie here looking for an ID. Thoughts?
  2. Could it be a recent bird egg fossilized?

    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?
  3. Possible Fossilized Tooth?

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

    Today I had an unusual opportunity to access a site rich in local Marshall Sandstone (Early Mississippian) bedrock as well as local-origin erratics of the same here in Michigan. Much of the bedrock in this area is covered by up to 100s of feet of glacial deposits. Look at the size of this chunk I was able to bring back. It's basically a "coquina" of molluscan and brachiopod shells. I think I have some new hernias now as a result of carrying this thing back to the truck (just kidding - I think...). I didn't have the aid of the wagon until I got back . But it was an exploratory trip and I didn't quite expect anything like this: Here is a close up of how rich the material is:
  5. Input requested (UPDATE!)

    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?
  6. Possible Crinoid or Sea Pen?

    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.
  7. Clam?

    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.
  8. Petrified wood?

    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!
  9. Fossil ID help

    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!!
  10. Paleozoic Coral

    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.
  11. Coral

    Another coral from Lake Huron. I'm not sure what this one is.
  12. Net-like Rock Patterning, Fossil?

    I found this rock at a beach at Lake Huron. It has a net-like covering. Is this actually a fossil?
  13. Mollusk Species

    A pretty neat little fossil from the coast of Lake Huron, Michigan. Two individuals, one on each side. Possibly Mesozoic in age.
  14. Tooth?

    A potential tooth from off the coast of Lake Huron. Possibly Mesozoic.
  15. Bone Fragment?

    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?
  16. Rock Identification

    @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?
  17. I'm looking for the best, easily accessible, and public places to hunt fossils in Michigan. I used to go hunting with my uncle in New Jersey, and would like to get back into it here in my home towns! Anywhere 1 hour or so around these towns is fair game. I would love to find a place where I can hunt with a good friend of mine, and indulge in some paleontology.
  18. Hexagonaria percarinata Coral.jpg

    From the album MY FOSSIL Collection - Dpaul7

    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

  20. Trip to Alpena, MI

    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.

  24. My Fossil Finds.

    This stone cracked when I picked it up. A nice surprise inside.
  25. My Fossil Finds.

    Hi, all. I just returned from a trip to northern Michigan. My wife was kind enough to indulge my fossil-hunting hobby, and I collected specimens in four locations: at a state park in Rockport, a city park in Rogers City, the Lake Huron shoreline in Alpena, and a rare (in Michigan, at least) road cut along a state highway. Here are some of my findings. First is a large Petoskey stone, or Hexagonaria peraninata.
