Sponge fossil from the late Paleozoic of southern Nevada?

I found this a few years back near (but not in) Guadalupe Mts National Park. Is it a sponge, coral, algae, or something else? Piece is about 6 inches across. Thank you for your help.

I recently found this tiny fossil at an exposure of the Middle Ordovician Benbolt Formation in SW Virginia. The fossil measures only a few mm in diameter. I actually found three of them, but two are more heavily encrusted by the surrounding matrix, and I do not yet have any tools to remove the rock. I wish I did because I think these will look really cool once they are fully exposed. Charles Butts listed Hindia parva ? among the fossils found in this formation. Since he listed it with a question mark and since there isn't a great deal of research material on the associated fossils of the Benbolt Formation, I thought to get some advice. I know that this species is familiar to the Middle Ordovician collectors of Wisconsin and Minnesota. What do you think? Any help is greatly appreciated. Thanks!

Hello, I'd appreciate your help with this one. I found this one at a Lake Michigan beach in Illinois. Silurian from the Racine formation. I believe it's a sponge or demosponge. Thinking the white dots on the vertical growth are pores, and the admittedly terrible microscopic photo of a small area on top of the rock shows some of its openings. Some of these seem to be filled with minerals that make them look like bumps, many others aren't preserved well at all, just show as faded round dots. Am I way off on this? TIA, Pippa

I believe might be a coral or sponge of some sort any ideas?

I believe might be a coral or sponge of some sort any ideas? Found around smithville Tennessee

Hello again Fossil friends! I have another fossil I need help with. Found with other shell and coral fossils in a river shore in north eastern Kansas, most likely Pennsylvanian. It looks to be maybe a sponge with exterior and interior... structure? Couldn't figure this one out. Maybe someone with more knowledge can ID it for sure.

Hello Fossil friends! I have a couple fossils(?) I'm going to see if I can get help identifying. I found all of them in the same local area of a river shore in northeastern Kansas, so I'm assuming Pennsylvanian time frame. I have some fossils that are obvious shells and coral, but these I'm not sure and would like your input! If you need more photos or angles, let me know. #1 I think is a fish vertebrae that's slightly flattened. It's about 1 cm x .3 cm.

From the Uni collection, found in a box with other assorted random fossils. sorry, no location data available

This is a sponge(?) microfossil in a fragment of a flint nodule. The flint has been quarried from the south of the British coast, which is mainly Cretaceous strata. It looks slightly like it's an imprint, but, upon further inspection, it is a broken off membrane. Currently (and slightly embarrassingly) I have only whittled it down to Echinodermata... I know, I know, spare me your applause, while my PhD's waiting! More sincerely, if anyone could shed some brighter light upon this, I'd be very grateful!

Leptomitus teretiusculus is a moderately common, thin-walled sponge species. Specimens range up to 11cm long and about 1,2cm wide. Literature: J. Y. Chen, X. G. Hou, and H. Z. Lu. 1989. Lower Cambrian leptomitids (Demospongea), Chengjiang, Yunnan. Acta Palaeontologica Sinica 28(1):17-30

I found another Ensiferites brandenburgi sponge that is now currently the largest ever found at 7 cm x 7.5 cm across. Part of the top displays lots of 1 mm spicules. Unfortunately the top of the calcareous sponge is mostly covered with caliche and possibly the limestone matrix. Is there any hope to prep this to expose all the spicules on the top? How? This could become a near museum piece thus I don’t want to practice my prepping skills in it. Help @Ptychodus04.

Hello all! I found this today and originally thought it was an archaeological item, I sent it off to the local officer and he said that he thinks it's a sponge fossil. I was wondering if anyone may be able to give me some more information please? Thankyou!

this was found in deer lake pa on a large piece of shale. whatever these things are they are over 12 inches long, branching and 1/2 to 3/4 inch in diameter. occasionally they appear to have straight vertical lines on the surface. I could see this pattern in only one or two places and could not get a clear photo. Help would be appreciated.

Hi. Could I have help with ID on these. they are all from the same small patch beside the road at the eskine range. WA.

Hello everyone, i found a flint ball in my field approximately 8 cm diameter, in Corfu island in north-western Greece, around 500 meters from the sea. I opened it and the enterior is like in the photo. Apart from the big cavity at the center, there are also many wholes around with red soil inside. Is the big cavity a fossil sponge? If yes, when is approximately dated? Thank you
-
These tiny fossils I suspect of being Receptaculites, but I'm not at all sure. The patch is about 12x12mm, about the size of a dime. It's on Martin formation dolomite from the Devonian, Verde Valley, Arizona. Other fossils on the same rock include Rugose and Tabulate corals and unidentified Brachiopods. Note the lichens growing in and on the sample. Any ideas?

Found in my backyard in southern california. Hard to get a good pic of it, but the center of it is a cone shape. Circular and wide at the top, with the pointy part towards the inner/center.

I found this in a sand pit near Kalkaska Michigan as a kid. It was in the vally wall around lake Skegamog. Next to it were a number of sand stones containing shell fossils. I don't know if it matters, but the pit wall I dug into was about 75 feet below the undisturbed grade. The stone I believe to be a sponge is approximately nine inches tall and weighs approximately 9.5 pounds. The chamber's are not uniform in size so I doubt it's being coral. The fact that there were no igneous rocks present makes me doubt pumice. I apologize that I could put up more pictures and close ups, but there was a limit on the upload size.

Hoping someone could help me identify the traces on this tooth? I found the tooth with pliocene fossil shells and the location does have middle to late pleistocene mammal fossils. I'm 90% sure this tooth is from a cape porcupine Hystrix africaeaustralis and the species still thrives in the area, from the pleistocene. If these are traces of a sponge then the tooth is a little older than thought. If it's another organism that has left the traces it could be late pleistocene or holocene with some mineralization taken place.

Stioderma coscinum from Rigby and Mapes 2000. Sponges are common in the Pennsylvanian Naco Formation of central Arizona. A friend and I collected pieces of Stioderma sponges near Roberts Mesa. Stioderma sponges have a set of very distinctive features that make an ID much easier than other Arizona sponges. They have spicules that are distally modified into layered rounded pustules that are set atop a surface with funnel shaped holes. My sponge has an edge that curves under and is covered with pustules. Further research might reveal what species they are. Stioderma genus erected by Finks: Finks, Robert M. (1960). Late Paleozoic sponge faunas of the Texas region: The siliceous sponges. Bulletin of the American Museum of Natural History 120(1):1-160 found at http://digitallibrary.amnh.org/handle/2246/1220 Stioderma coscinum found in Desmoinian Age Millsap Lake Formation in Texas: Rigby, J.

Hi everyone this is matt again today in the creek I found 4 different fossils in the creek . They are called fenestella, favosites, productus and a bryozoan fossil.
