Hello to all. I would appreciate some help identifying if this is a fossil and what it is. I found it in a canyon in San Diego and plan on taking it to our local natural history museum if it turns out that it is actually fossilized plant life like I believe it is. Thanks to the creators of this wonderful website and thanks to those of you who took the time to look at my post. I would also especially like to thank anyone who is able to help identify what this rock is all about.

I found this about 20 years ago while playing in a mound of dirt that my Grandpa had dug when building his new house. The location was near a creek in north, central Arkansas. His house is also near the Buffalo river in Searcy County, Arkansas, US. The measurements are 5 inches long (12.7 centimeters), 2 1/2 inches wide (6.35 centimeters) I’ve been hanging on to this since I was a kid. I’d be grateful to receive any help identifying what I have!

My son found this in Savage River MD. He found it in the River at the bottom of a 4ft swimming hole. The river does have a bit of a current, heavy after rains. Looked too odd not to ask if this is a fossil. Appreciate any help, thanks for your time. Mark

Fossil ID / Field Guide reference books - Southeast US?
SilverRead posted a topic in General Fossil Discussion
Could anyone refer a good fossil ID text book or field guide? Preferably US fossils but doesn't have to be that specific. I need something that is more advanced than a basic introductory/children's book. Been looking for awhile for a general fossil ID book with straightforward pictures + descriptions, but no luck so far. I'm a member of a local rock club. The fossil hunts are my favorite and I've gotten some interesting pieces (horn coral, blastoids, archimedes, crinoids, seed fern impressions, sigillaria etc) and received help ID'ing stuff from our more knowledgeable members but even some things they have not been able to positively identify or I've gotten home, cleaned things up and realized I might have something different. Plus I want to get more familiar with what other fossils may look like, pretty sure I have passed over fossils that I didn't realize were fossils...- 3 replies

I found this strange fossil near Sand Springs on the Arkansas River of Northeast Oklahoma back in 2013 or so. I was told by multiple sources that it appears to be a chunk of seabed. Is this from the Devonian/Mississippian period? Can anyone ID any of the fossils on this piece? Any help would be greatly appreciated! Thanks! I have a few other specimens I would love to identify as well! :)) ~Noah Benzing

Hellow everyone new to the forum. What I have found looks like a fossilized gastropod sea shell which was found from the gulf of kutch (65-2mya) late cretaceous-tertiary and it was found on the beach. Here is a photo from a local fossil park for comparison.

Found this while rockhounding pilgrim haven beach this weekend in southwestern Michigan to get anything not picked over during this years season when I came upon this. I have truly no idea what this could be, it looks like a fish to me but would there be any nice fossils this late in the season? And if so could it even be a fish? I thought we had corals, crinoids, bivalves, etc fossilized but this does not seem to be those.

I found this shark tooth in a shell pit near Orlando Florida. Was hoping someone could help identify it, and possibly an estimated age. This is my first large and perfectly intact tooth, so I'm pretty excited to find out what it belonged too.

MeAmLikeRocks posted a topic in Fossil ID
I got this at a beach in petoskey same as my last post and I'm fairly certain these are two corals, a favosite and one other that I'm not sure of.- 2 replies

The brachiopod fauna of the Leighton Formation is so small that I don't often find one that needs some help with identification. This individual does. The closest brachiopod that has the same characteristics is Eoplectodonta (=Plectambonites) transversalis, but it only occurs in the Dennys Formation. The Dennys Fm has quite a different fauna from the Leighton, but it is the closest thing I could find. My other option was some sort of small spiriferid. I will have to defer to @Tidgy's Dad for this one. Below are two pictures of it, first of the cast, and second of the external mold. Unfortunately, the fossil is rather damaged - the split did not cooperate with it. It is from the Leighton Fm, which is Silurian, Pridolian. Thanks in advance for your help!

Well, it has been a while since a post on the Silurian Leighton Fm. Had to make a trip due to family matters, and once I got back had a lot of work to do. I finally got into a position to start splitting and prepping more shale, and found this new little guy. I am torn between an operculum of a gastropod, and an inarticulate brachiopod. My main argument for an operculum is because of the shape - the only inarticulate brachiopods in this formation are Orbiculoidea and Pholidops. Unfortunately, I cannot find any reliable papers on the brachiopod Pholidops, it looks very similar but there is quite a bit of variation. The gastropod Australonema (possibly Cyclonema) is found in this formation, and the operculum of the genus is very similar to my specimen. On the other hand, the rarity of such Paleozoic opercula make me think that this is a brachiopod. And now for the specimen itself. It was not found in association with any gastropods, but was next to numerous Nuculites bivalves, some ostracods, and a tentaculite. The pictures below first show the two opposite halves of the specimen - unfortunately one was damaged when the shale split. Thanks for reading!

I have just found this little coprolite? yesterday. This is the second time a coprolite-like fossil has turned up in the shale from the Leighton Fm. I am not really sure on this one, though, due to the presence of crinoid stems. The fossil(s) are from the Leighton Formation, Maine; which is Pridoli, Silurian. The main reason I think it is a coprolite is because of its situation in the shale. The rest of the shale around it is relatively uniform, with no fossils whatsoever. The fossils present in it are one crinoid stem, quite a few ostracods, a very small Orbiculoidea brachiopod, and an unidentified piece of rather bluish-black material in the center, possibly some sort of shell. My main concern for its identification as a coprolite is the wide range of rather large fossils in it. I don't know what animal would have had such a diet, except possibly a very large detritivore - but I don't know of any super large ones here. The only animals that I can think of producing coprolites in this formation would be eurypterids, phyllocarids, agnathan fish, and possibly trilobites. A coprolite of this size I would identify as an agnathan fish, but I would defer to some of our fish and coprolite experts for this. @jdp @GeschWhat Below are two photos of the two different sides of the coprolite. If you would like closeup photos of some of the fossils inside the coprolite, I have some available. Just did not want to overload this post with too many photos. Thanks in advance for your help everyone!
