This looks like a fossilized mushroom. But I think it's a cone coral.

I found this out of a field in western Iowa and I’m not sure what kind of coral it is

Like the title states… we are stumped. Found on the Kaw River as well. Thank you in advance, all suggestions appreciated!

This place is just like Wrens Nest Dudley i.e. Silurian. I like both places but find different things at each. Personally I have found more Trilobites bits at Wrens Nest. 1 - Arachnophyllum murchisoni Coral, top view 2 - Amphistrophia funiculata Brachiopod 3 - Favosites Coral 4 - Halysites Coral 5 - Heliolites Coral 6 - Kodonophyllum truncatum Solitary Coral 7 - Labechia conferta Stromatoporoid sponge 8 - Leptaena depressa Brachiopod 9 - Trepostome Bryozoa

I found this on the Elk River West Virginia. It weighs about 8 lbs. Any particular info would be awesome. Thanks!

So, what do I do to separate a fossil from the sediment? Like a coral fossil as example. Do I use acid? I heard you can also use vinegar but I don't know. Also, what is probably the best prepping starter kit online, or in hardware stores? I want to get a full set of stuff but don't know where to find a good bang for your buck. I really want to get into that type of work soon.

Hi all, a friend of a friend found this on the most northern point of Lake Superior, off Copper Harbor. I suspect it is fossil but to my eye it just strikes me as modern. Maybe escaped aquarium coral. But this person also claims to have found other pieces of corals there. Might anyone be able to say if this agrees with fossil corals of that area or is it a taxon not to be expected from the Paleozoic? Thanks!

Yesterday I was able to take a trip to the Silurian Racine formation of Southern Wisconsin. This site was easier than others due to the clear stratification, and I was able to see some of the reef overlay and underlay. finds included: my first dolomitized crinoid calyx, a nice fez-looking coral, some Bumastus trilobits, and what looks like a Cornulites impression? I’m curious if anyone has thoughts on the circular impression with calcite growths in it- unsure if it‘s an imprint or just a gap with mineral growth. Included a fun extra picture of old and new critters paired together.

It's apparent there's some coral in one corner atleast but the impression is what confuses me. There almost seems to be a discoloration following the fin like marking. I'd be very appreciative for someone's opinion It was found at the beach, on the edge of the water. Sandy Beach, Shediac, New Brunswick

Hello everyone, it's been a while since I've been a while since I've been out to collect fossils but yesterday I finally got to enjoy some time collecting and had some interesting finds I thought I'd share. Yesterday morning I got to meet up with @Jeffrey P who showed me his vast and beautiful collection of fossils before we went to collect two locations nearby in Eastern NY. The first location we visited was the Glenerie Limestone, a very interesting location due to the diversity of organisms found there and the unique preservation which results in many silicified shells a number of which are completely out of matrix. This was my second time collecting at this location and as it had just been snowing and everything melted, there was a lot of nice freshly washed out material to pick through. By far the most abundant fossils here are brachiopods and of those, the most common is probably Leptocoelia flabellites, I collected a few of these and some appear on the larger matrix pieces with other fossils but they're really common so only a few were kept: Meristella sp. are also pretty abundant, I picked up a few that I thought had nicer preservation, or were complete as those are not as common at this site These are the shells of two spiriferid, I collected a number of these last time, the most common ones are Acrospirifer sp. and Howella sp. I believe but I do not know how to differentiate between the two This piece of matrix had some particularly nice spiriferids, one was pretty big for the site and another on the side of the piece has really nice preservation of some of the finse structure on the outside of the shell. I also found a Rensselaeria sp. Terebtatulid brachiopod, my second from the location, this one has more of it preserved although it is quite distorted and with little of the shell material but I still kept it as I like these Devonian Terebtatulids and they are not as common. Here's a tiny complete brachiopods I picked up, not sure about the ID yet, the detail preserved on such a small shell is actually pretty nice but the camera doesn't show it that well. Two of the brachiopods found appear to be inarticulate brachiopods, although I'm not sure if it's possible to put an ID to either of them, the first is preserved as an impression, I did look at some of the internal anatomy of lower Devonian inarticulate brachiopods and this does look a lot like Craniops sp. but I don't know if I could call it that without further evidence The other has some shell material but it's small and not completely exposed so I am not sure if it can be identified or even if it is an inarticulate brachiopod And some miscellaneous brachiopods I haven't yet Identified: Here's another item that confused me, it appears to be a brachiopod from the overall shape, as it is flat on one side and is in the shape of a semicircle, but if it is a brachiopod it has some kind of unusual epibiont on it with an unusual structure unlike anything else I've seen, does anyone know what this may be? Other than brachiopods, gastropods are also fairly abundant at the site, last time I was here I found a couple but nothing too special. This time, I don't know if it was the freshly washed out material, a better pattern recognition or just pure luck I found a lot, of different sizes and different quality. I was very happy to find these they're really interesting and I love the way they are preserved here, here is most of them: most of not all of them are Platystoma sp. I believe. And finally, I also found a coral, the first time I was at the site I found a tabulate coral which @Jeffrey P told me is the first he'd seen ever from this site, and this time I found a solitary rugose coral. Unfortunately it is cracked as it was laying on the surface, exposed to the elements but I was able to safely get it home and I'm currently trying to stabilize it with some glue, hopefully it will remain intact. I believe it might belong to the species Enterolasma strictum. After Glenerie we stopped at a site not far away which was in the Middle Devonian, lower Hamilton Group, part of the Marcellus Shale, also a very interesting site which was new to me, and we had some nice finds there too which I will post later once I get them photographed. Thanks for looking! Misha

I finally found some quality Agatized coral...

Sorry for so many posts back to back but I found this coral inland in a power line that's being dug up for power poles. Not wooden poles but huge metal poles. They use fill rock to stabilize the poles after they put them in the ground. All the fill rock is small white chalky rock with chalky shells. Idk if it's from the fill rock pile or something they dug up from the ground. Thanks for any help...

Hello!! Any insight on this would be appreciated! My daughter found it today diving in the ocean. We are in south Florida. It’s roughly 4inchesx3inches and 303g (0.668lbs) thanks!
