New to this platform and web forums in general (other than discord). But uh- i was at Lake Ray Roberts beach yesterday and found this strangely shaped rock in the water that i think might be a sponge or coral due to the abnormal tiny holes in it. I’m no paleontologist but i know that the area used to be underwater, so it would make sense. If anyone can identify these photos, it would be a huge favor (and if you have discord i might draw your fav dino as a reward-) (btw, the fossil’s about 3/4ths the size of my hand, and i’m 5’11.)

Found these three rocks in an outcropping of Niobrara Chalk in Southeast SD. I suspect they are sponges or coral of some kind. Pics 2&3 are both roughly the diameter of a penny, pic 1 is probably 20% larger. ID would be greatly appreciated!

Stromatoporids, other sponges, or not a fossil? Thanks!
SilurianSalamander posted a topic in Fossil ID
All collected in gravel and beach rocks from SW Wisconsin. Thanks so much for the help! I love this community:) -
Despite weathering, I was hoping there may be enough features for an ID. My initial impression was that it could potentially be a bivalve. However, after seeing a photo of fossil sponges from the area (see last pic), I think that is a reasonable consideration as well. Thanks for looking!

sponge or tabulate coral? Agatized Paleozoic fossil found in a gravel pit
SilurianSalamander posted a topic in Fossil ID
-
Most of what I find in southeast Texas is mio-pleistocene, and fresh water based. But at times older cretaceous stuff washes down. Since it's rare here, I'm completely clueless as to differences between oysters, corals, rudists and things but would like to learn more. I found this a while back and it seems to have very distinct patterns on the outside and inside. From searches, I thought maybe a broken piece of rudist, but I wouldn't know one if it bit me. It just doesn't look like normal rock to me. Any guidance would be appreciated. @JohnJ

I love my backyard, I don' love being clueless as to where the previous owners purchased the rocks from. I am fairly positive that they are a mixture of at least two different styles, one of which I know is a river or lake mixture. (I was able to get one person on another forum to tell me they look like possibly Michigan Lakes stones) What I did not know, is that coral and sponge could be found in fresh water sources, any body an expert in this sector? Or if you have any opinions on the Lake Michigan suggestion, please let me know what you think. When I am more familiar with the different forums and navigation of everything, I will make sure to post the ones that I have been assured are coral specimens.

Hello, I wish I could tell you exactly where this piece came from but "east of the Mississippi, perhaps Massachusetts/upstate New York" is the best I can do. It's actually been worked by humans hands I believe, meaning it is an artifact of some kind... but what is it made of? I've never seen anything quite like it and I'm wondering ion its. a fossil of some kind. It's about 1 in (2.5 centimeters) but it's clearly been broken so it was part of a larger object/spall. I'm sorry the picture of the bottom where the break is isn't that sharp. Thank you for taking a look and for any help/information you might provide!

Went to Ruxton England looking for my own mammoth. Brought home some large rocks instead. Not sure what to make of the orange inclusion in this piece of flint. The whole flint is about 3 by 5 inches with multiple rough spotty enclusions There is significant discussion as to what these flints represent, one concept involves the death and collapse of glass sponges as in: https://www.flint-paramoudra.com/flint-nodules.html Is it a dying glass sponge, a worm and worm burrow, or something else entirely. Help will be appreciated, thanks

Could this be a sponge? Note the radial structure and the occasional branching rods. Collected in Missouri, but location and age are unknown. Also, the specimen is sawn to 3/4" thick and the fossil doesn't extend into the sawn area! There is a lot of tiny crinoidal hash in the matrix rock. The light blue grid is one inch.

I would welcome any help identifying a fossil that I suspect to be some sort of bacteria/coral/sponge/aquatic item. Sorry to sound so ignorant about it, but I really don't know aquatic life by sight. The fossil is 6 cm long X 4 cm tall X 2 cm thick. Found in an Upper Cretaceous area, Kirtland Formation of northwestern New Mexico. The fossil has the small pits located around the edges and on the opposite side too. Thanks!

Unknown item (sponge?) from the Credit River in Mississauga, Ontario
Monica posted a topic in Fossil ID
Hello there! Last month, I visited the Credit River in Mississauga, Ontario, Canada (Georgian Bay Formation, Upper Ordovician) to look for some fossilized corals. In addition to a bunch of weathered colonial rugose corals, I found an item that I think is something, but I'm not sure what - perhaps a sponge? Here are some photos of it: Side view - dry: Top view - dry: Top view - wet: Thanks so much! Monica- 10 replies

Hi everyone, I found this in marine pliocene-pleistocene sediments. The rock is a sandstone with large cemented elements (pebbles and fragments of shells). What is that round object? It has an ornamentation made of small holes, fairly regular, under the surface the holes seem to widen into small chambers (as you can see in the broken point). Could it be a coral or a fossil sponge? Dimension of the round object: 40x25mm Thanks

I found this twiggy fossil at the Lost Creek Dam site in Jacksboro Texas. It's the Finis Shale Member of the Graham Formation, Upper Pennsylvanian. I thought it might be a Fissispongia jacksboroensis but now I'm wondering if that is right. The two branch-like protuberances have some wavy striations on them I haven't seen before. Any ideas?

While travelling in British columbia I picked up a couple of fossils, one has something like a fish or strange leaf on it with tiny little oval shapes and shells. Whatever was the focal point of thus fossil appears to have been damaged. I am very interested in what the small oval shapes are as there are many of them and they are on both sides and visible in the cross-section of the stone. If I wet the ovals I may be able to get a better contrast picture. The other is possibly a fossilized sea sponge. Although there is no surrounding stone, The Pink piece seems way too heavy for its size and I was able to match it somewhat to a piece someone found in florida but they were unsure as to what it was. The seller has had it for about 40 years apparently as it has belonged to her mother. Neither seller had any information on them. Also got two pieces of fossilized wood, working on cleaning them up
