Hello, I was trying to find the identity of some marine fossils I found, and found this great forum! I am from Montana, but have been wintering in Yuma, Arizona. I have been finding all sorts of neat rocks and marine fossils in the desert outside of Yuma where the Colorado river had once flowed into a large ocean. I have found several roundish rocks that seem to have fossilized marine life in them? I was told by a Coprolite collector that is a characteristic of Coprolite found in this area? I would appreciate an ID on the specimens, or speculations as to what they are? Below is one specimen, different angles, notice the square holes!? Thanks!

Can you please help ID this? Found close to the border of WI/IL. It seems spongelike but the inside chambers leave me guessing! NOT a professional. Just like to find cool schtuff'.

Please help me to identify these two fossils. When I picked up these rocks, I thought I had found corals, but now, looking at them from all sides, I'm stumped. What throws me, is that the pattern on each of the two fossils looks the same all around the rock. No vertical structure or growth pattern, anywhere. So even if these are just broken off pieces of a much larger fossil, corals still would show vertical structures on the sides, right? But no "sides" are visible here. Confusing. Thanks so much in advance for taking the time to share your knowledge. #1: Dimensions: width is 2.2cm; height is 3cm, the individual circles vary quite a bit from <0.5mm to >1mm. Detail: #2: I wouldn't mind if this one is geological, as I collect more purely geological rocks than I do fossils, but I don't think this one is just geological. Dimensions: width: 3.5cm; height: 2cm; individual "dots": max 1mm

I picked up this jasper for its banding. Only later, when checking the rock through my hand lense did I discover what I think are a bunch of little rugose colonial corallites at the top and bottom of this rock. If these are indeed corals, all but one lack most detail in the center. If septa are faintly visible, they look differently preserved than on any of my other coral specimens. Mostly it's just circle after circle here, and areas full of "pores". Now that I'm looking at them on my larger screen, the "pores" themselves seem to be corallites - microscopic ones. The black dots are in the center of honeycomb like shapes. I'm confused now, are these the fossilized remains of one or two type of corals, or maybe a colonial coral and a bryozoan? Sorry about the bad quality and distortion of the pictures taken through a microscope lens on my phone. Please help me ID these tiny hurricane look-alikes. As always, thanks in advance. Here a couple of them in various states of preservation. Lots of them have a vug where the center of the corallite would be. Here the circles look like growth rings and in some areas the "pores" are clearly visible. #1: This one is the only one with detail in the center. Septa? #2: a vug at the center seems all that's left here. #3: Just pores in the center, and in between the circles, maybe the faintest lines that could have been septa? #4: Area in between corals, with faintly visible honeycomb shapes: Detail of the above: Another area in between, looking somewhat different again:

Found in northwestern New Mexico in an Upper Cretaceous area. Specimen was wetted with water to bring out detail.

I found these all on the same hillside in Arizona, redwall limestone, Mooney member, Mississippian. I'm pretty sure 1 is a Hexactanellid sponge. The others I'm less sure of and would like to hear more experienced opinions on them. The second picture is just the backside. Thanks for looking. Bob @Arizona Chris

On December 28th I had a chance to do a little searching at Brownies. Spent most of the day in a gentle rain but found a variety of the usual suspects. More than anything, it was amazing to be on the water in the fog and rain. Super quiet and beautiful. In the shark department, I was stoked to find this 3.1" Meg (uncleaned) in situ. It keeps getting lighter, so I suspect it will be near white once done. I also came across some of these corals/sponges. One has a nice cup on it that looks to have been oriented upwards along with a barnacle, like a sponge. Any thoughts on ID? They look to have come from Zone 10:

About eight years ago I posted about some odd fossils that I found in the Keyser formation limestone and the consensus was that they were roots of Hexactinellid sponges (glass sponges). @piranha dug up some pretty good evidence that these are indeed from Hexactinellid sponges. I recently visited the quarry again over my Christmas break and found more examples. I'm wondering if there are some fresh takes on what these may be and if anyone has found something similar? For reference, these come from an old quarry near Mapleton, PA and are from the Keyser formation which is thought to straddle the boundary between the Silurian and Devonian periods. The layers they were found in were close to layers of the Tonoloway formation which is Upper Silurian in age. Specimen #1 - This is the most interesting example I've found as the threads all seem to come from a central area and radiate out. Also note that they are layered and some have hook like endings. Specimen #2 - This is a large plate with many clusters of these threads criss-crossing each other, but all in relatively same direction. Specimen #3 - This is the first example I have that is associated with any other fauna. The Brachiopod is a small Atrypa reticularis Thanks for looking and any suggestions are welcomed.

Among marine fossils of Pliocene , ostrea , cardium etc. Any possibility for sponges ?
-
I found those spherical, almost shapeless (or vaguely champignon-like) pieces in an SE Pyrenees Upper Campanian site with rudists, corals, ostreids and brachs. Could They be Siphonia sponges? A broken part of the last one

I found this 4cm wide "knitted mushroom cap" at a beach near Kenosha in SE Wisconsin. I thought at first to have found a tabulate coral, but looking closer, I can't see any corallites at all and oddly, the top, instead of flaring out to a solid "table", curves back into itself, with most of the center missing altogether. All of this made me think that maybe this is a sponge? If not, what could it be? Top: Bottom:

I found this in my Seattle area yard, near the dead stump of a small maple. After washing and bleaching the septums appear filled with sand and shell bits. There is also something growing throughout it like a veinous system—likely plant? It is heavy. There are striated and mineralized layers. There is a ventricle feature and a faceted stem—it’s disturbingly brain-like. I feel honored to have finally guessed my way through your captcha (respect!)~~hoping someone can identify this oddity. Best guesses so far are coral or fungus, but I’ve not found any examples sporting this stem canal...

Hello, I'm posting this for a buddy of mine. This piece was found in the French Joe Canyon area near the town of Whetstone, AZ. Any ideas if this is an actual fossil or an odd looking concretion? Thank you for any and all help.

Good morning, I was hoping that somebody could let me know if one of those is sponge and the other one is coral? Or if not could you please tell me what they are? Also, these were found in Glen Rose Texas, in the country at a creek bed . And that is Somervell County

Figured I’d post one more while I’ve got the collection out. When I was younger, my grandfather had a gravel driveway put in. I assume it came from Ohio, although I have no idea in truth. I frequently picked through it and found a few fossils. The gravel is clearly made of marine sediment for the most part - I’ve found brachiopods, trilobite fragments, shells, etc. I just wonder what these two could be? The first one has a couple of different structures in it - I’m thinking sponge or coral for the main part. The second, I have no idea. It looks footprint-ish, but this doesn’t make sense due to the marine nature of the gravel. Any ideas? Thanks, Nate

One of my finds from yesterday. Found it on the surface in a creek bed here in W KY. (That is 99% of my finds!) Apologies for not knowing the geology & time frame. Not quite sure how to go about figuring that out yet. Could this be a sponge or coral? It's about 12 cm long, 9 wide at the widest, & heavy, probably 2 lbs. at least.

Hi to Forum members; I am an amateur rock collector who likes to look for fossils. For the most part I have not found anything fantastic but I am hopeful. I kindly request any information and or comments about a recent flint specimen from my back garden in Ipswich, Tuddenham Road. I have other photos of the flint that show unusual structures. On those photos, I used my photo app to adjust the exposure to get more fine detail. If it will help, I would gladly share. Also from my back garden, I found a petrified seed/pod/nut shell. Can someone help me identify what it is. May thanks! Munchy2

Stumbled arcoss what a seller is calling a careaonitas sponge from the Hopkington formation in Milwaukee county Wisconsin. I tried to Google careaonitas sponge and didn't find anything...is it possible to have a different name or is it simply a misspelling by the seller and my Google skills are weak?

Hi all! I found some of these fossils at a rock shop and I have never seen their kind before. I honestly I’m not even sure what it could be. As far as I know they’re from Morocco, but that’s just a guess. Any ideas?

These things are very small and difficult to find but I came across a stone that was littered with hundreds of forams and these spicules. I don't recall seeing anything that look like a sponge so I'm very curious as to why there were so many of these spicules being found in this stone that was found in a desert.

Hi this is matt again the other day in the creek I found this strange fossil coral can anyone id it for me ? here are some photos

I found this fossil on a hiking trail near Eureka, Missouri. It was on top of a hill. There is a natural spring on the trail at the base of the hill. I think it is some kind of coral or sponge, but I can’t find any pictures that look exactly like this so I don’t know what it is. Any help you can give me is appreciated!
