Shouting out from the New River Valley in Virginia but my new interest comes from a recent trip to the shores of Lake Huron in Michigan. It started by wanting to pick up a few pebbles to make some photo frames to gift to family with photos from the trip. I started picking up pebbles for my project and within about five minutes found what I am pretty sure is a sand shark tooth... then a couple of other cool finds and the pretty colors of the wet stones... and well, I just got obsessed and I didn't even have any idea what I should be looking for. Now I'm on a mission to identify what I picked up! And of course will be looking for more interesting finds.

Hi sebosgal, I live in Alpena, which is on the shores of Lake Huron. There is a large variety of rocks here, including lots of fossils that come from the local limestone bedrock and also lots of rocks that were dumped here by glaciers. The glaciers brought rocks from lots of places, so they can be hard to identify. Personally, I'm terrible at identification, but I may be able to help you with the easy ones. Of course, I'd need pictures to do that. You'll need a photo hosting site like Flickr to host the pictures and then post the BBcode here. I can give you better instructions if you have trouble doing that. Around here, we find lots of sea fossils like brachiopods, crinoids, Petoskey stones, other corals, etc. There have been prehistoric fish found locally, but I've never found any, I've never heard of sand shark teeth being found, but maybe. I have found sea urchin spines which could look like tiny sharks teeth I suppose. Got some pictures up so we can help you! By the way, welcome to the forum.

know the "tooth" would be odd. But I swear it's what it looks like! I know I have some granite and some unakite. Lots of coral fossils. Some pretty neat crinoids. Here is a link to my Flickr album with a good sampling of my finds. flic.kr/s/aHskz3bfmY

Hello and welcome from Virginia Beach!!!! Nice to see another Virginian. I saw a lot of familiar rocks in your pictures. No doubt you will easily get them ID'd. Drummond Island Rocks can help as well as Jugglerguy , who you already "met" ... and snowmom, too.

Great selection of rocks and fossils although none are really prime subjects for tumbling. Your petoskeys and favosites are best worked by hand. The granites will shine up in a tumbler but will not have a nice smooth finish. The softer minerals will eat away faster than the hard minerals leaving a textured surface.
Were you hounding a private beach in Port Sanilac? I don't remember seeing that variety of rocks at the public beach near the boat launch.

Chuck Yes to the private beach, we rented a cottage for the week. I might have strayed to the neighbors a little but they didn't tell me to leave (I think they were renting too!) and there was a little stream going into Lake Huron about 4 houses up and I found some fun ones there. Knowing that I didn't own a tumbler I mostly went for stones that had naturally been tumbled smooth. I have quite a few more than what I took photos of last night. That was primarily the "fossil bag"!

So once you have access to the beach, you can walk as far as you want to. I can identify a few of those for you. Most of the speckled, colorful ones are granite as you've already said. This is cladapora coral. The white coral parts will shine up pretty good, but the black parts get sort of a matte finish. I like this stuff. It can be tumbled, but takes a special technique. If you ever decide to get vibratory tumbler, I can give you instructions. You have several pieces of this. The black matrix contains oil. This is mostly the same, but there are some crinoid stems in here too. Petoskey stone. I love these. Nice find. Crinoid stem Favosite, or Charlevoix stone: Partial Petoskey Pudding stone. These are very popular in Michigan. Favosite Crinoid stems Horn coral, I think. I think this is another horn coral. More crinoid stems. Favosite Petoskey Some sort of coral, I think. I like this one! Another Petoskey stone Probably chert I didn't see any unakite in your pictures. Here are some pendants I made. There's a pudding stone and a cladapora here, which you found. The other one is Kona dolomite from Marquette, MI.
