I posted a little report a few days ago about my latest outing to the Danube Valley and now I'm adding this as a sort of after-thought. I had already deposited this sponge in its unprepared condition in the dregs crate since I just didn't have the inclination to clean the matrix out of the interior. Sponges are anyway just a byproduct of my search for ammonites and I always keep telling myself you've already got enough of the things. Well, my grandson was over for a visit the day before yesterday and he spotted it. Now he just loves to putter around in the workshop when he's here, and since we had some time on our hands I figured I could let him have a go at it. He did a pretty good job at hollowing it out before his mother came to pick him up, so I thought I might just as well finish it off. Today I sat down to scrape off the last bits with the stylus and it suddenly broke up into a few pieces. No problem. Just glued them back together and finished it off with the air abrader. I believe it was worth it in the end, since I believe I have a genus which I don't have in the collection yet. I'm not really sure, but at least it looks that way. Sphenaulax sp. ? from the late Jurassic Kimmeridgian. Length: 10cm. Diameter: 12cm.

I just pulled this out of a box of old fossils, but I'm not exactly sure where I originally found it. I think it is from the Carter's limestone, middle Ordovician, in the Nashville, TN area. It has a similar shape and size (~2 cm dia) to Hindia, but I have not seen anything else with this distinctive pattern of parallel criss-crossing ridges. Any ideas? Thanks

At first I thought this one was a rock, but looking at it closer it looks like it could either be a coral or a sponge, or a rock with holes in it. You guy know what it is?

I found this along the Fox River in Elgin, IL. At first I thought it was a stromatoporoid fossil (I find them everywhere in this area), but upon closer inspection I couldn't see anything that looked like pillars or laminae. Someone suggested chaetetid sponge, or a stromatoporoid that was distorted by silicification. I can't find any photos that look like my spec. except dino bone and we don't have those in northern Illinois. Is it a natural formation, crazy looking oolites? I'm totally stumped! More pics

Found in a small stream in south east BC Canada. About 2km west of continental divide. It's very heavy for its size. The filaments have segments on many of them and have and organic appearance. Location would suggest Devonian or Permian I'm guessing. It's hard to know with fast flowing creek finds this high in the Rocky Mountains. Any info or ideas be appreciated. Cheers.

2 photos of this. is 2.5 cm tall, in the area which is 3-5million years range i found also a lot of the 3rd photo, oysters and other fossillized stuff.

I apologize that this is just one photo taken by my phone, but that is all I have to use at the moment. This fossil (about 6 cm long) is from the middle Cambrian Spence Shale of Oneida Narrows, Idaho. I am leaning towards a sponge? Does anyone have any idea what this is? Thanks for the help!

From the album MY FOSSIL Collection - Dpaul7
Regispongia Sponge fossils Bangor Limestone Formation in north Alabama Mississippian Period (ca 325,0000,000 yrs old) Sponges, the members of the phylum Porifera (meaning "pore bearer"), are the basalmost clade of animals, as sister of the diploblasts. They are multicellular parazoan organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Kingdom: Animalia Phylum: Porifera Class: Calcarea Order: Heteractinida Family: Wewokellidae Genus: Regispongia -
Hi All, This is one of a kind - we found only ONE of these in 250 pounds of Permian limestone that we reduced in the acid bath over the past few months. Its a lovely thing, I think its a stellate miniature ins branching sponge, but Id like your opinion. Its hollow inside the main tube, and no pits or chambers like a bryozoan. Anyone seen a tiny sponge like this? Here is top and bottom shots: (20 layer stacks!) Your opinion is appreciated!

I was doing some fall work in the garden and I dug a hole deeper than usual to start a compost pile and this was in the ground. It ppears to be coral or something. Can anyone see an outline or give any advice? I didn’t try to clean it as it seemed to be fragile. Thanks!

Hello, I received this specimen that I believe is a fossilized coral or perhaps a fossilized sponge and am looking for help in identifying the species and age for a museums collection. Any help would be appreciated!! Thanks, Holly

A few months ago I was helped here to identify a clam fossil and now near the same area I have found this. It doesn't match any images that I have found searching. Thank you.

Hello! I collected this rounded stone in Southern Ohio, actually to paint on originally, and became enamored with what appears to be a fossil algae on top so kept in in my collection. Recently I inspected it through a loupe and noticed the sponge like pores for the first time. I tried to show in the photos that there is a transition or directional grain to the pores that I've seen in whale bones and sponges that washed ashore when I lived in the Pacific Northwest. It's sized at about six inches at the widest, and is a sandstone rather than the expected limestone. What do you think? Is it a sponge or a type of coral?

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

A fossil sponge from the Permian Fort Apache Limestone
Arizona Chris posted a topic in General Fossil Discussion
Hi all, Fort Apache sponges are quite uncommon, only one sizable specimen was obtained from over 200 pounds in rock. But it is well preserved, and show the major features of fossil sponges from the Paleozoic. To be more precise, from our first locality, where nearly all the ostracods came from - we had no sponge material at all. The second new site, a half a mile further down the trail produced this specimen from about 35 pounds in limestone. They were also with numerous bryozoans and gastropods in the same mix. The one sponge we found is a calcareous type sponge that have been preserved by silica replacement. What I dont know is if this is a part of a big flat sponge, or perhaps a section of a tubular one. Maybe some of you can ascertain that. This is the largest specimen we found, it was in a class by itself! About 4 cm long and about 1 cm thick, this fragment of a large irregular sponge had excellent pore and ostium details. A millimeter scale is at bottom. 3.5x view . A closer 7x view of its surface reveals the very "spongy" appearance of the type you might wash your car with. The holes are the pores which take in water to an interior cavity for respiration and feeding on plankton. If this was a part of a large flat sponge, those larger holes might be the osculums and the tiny surface pores the in current holes. Even closer at 20x, this shows the pore details more clearly in a massive 16 focus layers stacked image. There have been a few false alarms on these calcareous sponges. Some of the really worn down bryozoans that are wrapped around urchin spines look indeed like a tubular sponge! We continue to look. This last weekend, me and my auxilliary rock hauler - I mean my wife - packed out another 36 pounds of promising rock from the second richer locality along the Highway 260 Trail east of Payson here in Arizona. We hope to find more! Thanks for looking, its a pleasure for us to show what we have found so far!- 2 replies

I believe i found my first Ordovician sponge fossil while hunting road cuts. Can anyone confirm if this is an Astylospongia or something else?

From the album Delaware Fossils
Found on the beach in New Castle, Delaware. Known Paleozoic fossil area. Identity unknown. -
Hello all. I believe this a form of sponge but I'm not sure. It was found on the Norfolk coast, UK. Any help appreciated, thanks

This is my property, about 100 acres total. About 25 miles south of grand canyon and just 6 miles from grand canyon caverns at 5400 feet elevation. The first picture is a hill just outside my door, take the dog up this everyday when we go for our walk. Every rock in this picture has fossils on them. An example is the second picture. About 1/8 mile into the trees there is a trail I've made over the years with the quad. I've just recently realized a section of that trail is like an ancient seabed. All red ,airy rocks -light but hard to actually break. Every rock you pick up is embedded with fossils, mostly shells I think. An example is the third picture. I'm thinking this was perhaps a sponge/coral reef because of all the tiny holes or was this just sediment? Any thoughts or comments would be most appreciated. Thanks (Oops, wasted too much memory on that hillside, will post red rock separately ) This is the example of the red rocks that make up the trail

From the album Georgian Bay Formation Outside of Toronto, Ontario
Stromatocerium huronense (Billings, 1865) Late Ordovician stromatoporoid sponge. Found along the Credit River at Streetsville, Mississauga, Ontario. Collected as a loose specimen, most likely coming from the Stromatocerium reef of the exposure this came from. Georgian Bay formation, late Ordovician. There is a tiny Favistella alveolata coral colony growing on the edge of the specimen, perhaps this was a commensalistic relationship? Specimen is 12 cm long. However this species in the exposure where it came from can grow beyond a foot in diameter as mounds. -
This is another picture with a ruler so you can tell the size of the sponge that I posted the other day. Perhaps it will help in identifying it.. Thank you.
