  1. 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.
  2. 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
  3. 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?
  4. Sponge? Coral? Fish scales?

    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?
  5. 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.
  6. strange coral that needs ID

    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
  7. Missouri Fossil ID Help

    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!
  8. Hi everyone this is matthew again today in the creek I found a neat coral fossil called syringopora retiformis here is a photo
  9. Fort Apache Limestone finds

    While dissolving an unknown 2 inch long sponge from the Permian Fort Apache Member of the Schnebly Hill Formation from northern Gila County in Arizona I found several silicified brachiopods with spines. Several Bellaclathrus spinosus brachiopods were present ranging from 0.75 to 1.5 inch across and had spines as long as 1 inch. Thankfully some sort of sudden but gentle event buried the sponge and brachiopods preserving them for me to uncover.
  10. I would like to clean the surface of this coral to try and remove the dirt. The dirt is really embedded (i.e., not removable with water alone). How would I go about doing this?
  11. I was wondering if someone could help me identify this fossil found over the weekend. It was found in South Bend Indiana. Because it was found in Northern Indiana, the fossil isn't from around here and was probably deposited by a glacier from somewhere up north. It is approximately 12 cm at its longest point and about 4 cm wide. Thank you for your help!
  12. Middle Devonian Stromatoporoids

    These fossil stromatoporoids came from the Traverse formation, Potter formation, Bell Shale, and antrim/dundee formation locations near the north eastern tip of the Mitt in Michigan USA.
  13. calcareous sponge spicules

    I have read that finding spicules preserved in sponge is quite rare. I am finding sponge fossils with what I believe are spicules, but the fossils seem to be all calcium carbonate, no silica. this seems to me to show the original sponge body was aragonite or calcite based. This was found on the north eastern side of the tip of the Mitt in Michigan The area is considered Middle Devonian, but these were found on the shore of Lake Huron, so there is also the possibility that they are glacial transports. Comments welcome.
  14. Ordovician Coral or Sponge?

    Came across this fossil today while out enjoying the sun. I've found coral before but the little cavities are usually infilled, this is like swiss cheese, wondering what it is. It feels like a pumice stone in weight and texture. Thanks in advance!
  15. Archaeocyathid?

    This is a fossil I am looking at purchasing. I asked the seller for a better photograph and the photos below were sent to me personally, so I do not believe this is in violation of the terms of the site (though I really do apologize if I have inadvertently broken the rules and I will immediately remove the content!). I believe the round fossil in the center to be an archaeocyathid, but I would like to be more certain before I pay to have it shipped from southern Australia. Unfortunately, that is all of the information that the seller has shared with me about location, so I don't have useful information like formation. I am not certain whether the subdivisions that I am seeing are the result of recrystallization or reflect actual septa. Thank you for your feedback!
  16. Missouri marine fossil ID

    Hello, In my third mystery find around the Kansas City and Blue Springs, MO areas I found these specimens. And I have yet been able to find any photos on the internet that can come close to their character. Can anyone identify what are these tiny egg-like beads? I hope my photos help. Thanks for your attention.
  17. Missouri marine fossil ID

    Hello, I live near west Jackson County, Missouri. I found this fossil while I was walking my dog. It was part of the landscaping for the front of a building that has been there for 20 years or more. No one knows the origin of the material for the landscaping. Lots of reading, I found most of the chert in the landscaping has crinoids as a point of the time period, Devonian? Can't find any photos to compare it with on the internet, been trying for 2 months, a crash course on paleontology 101. I see Missouri in a different light from it all. Can this be identified? Thanks for the opportunity to share.
  18. Silurian Sponge? Coral?

    Hello, I can't seem to ID this fossil found in Silurian reef rock, Chicago area. I made some slices. Any help appreciated.
  19. I have another oddity here. Found on a Tampa Bay beach in Florida. It is about 3 inches long, brittle but light weight and hollow, with one end open and one end sealed. The side hole or spout attaches to the larger opening. I did some research and it resembles a calcareous sponge. Is it a sponge? Is it a fossil or modern? Thanks as always to a great group of people! Please see 5 pics below.
  20. Florida Agatized Sponge or Coral?

    I found this awesome glittery piece on the beach in Tampa Bay. It is kind of layered and has a cheesecloth pattern on it. It is about 2 x 2 1/2 inches in diameter and about 1 1/4 inches in height. It is lighter than my typical coral finds. It has what looks like 2 bore holes that go right through. I'm not seeing any corallites so I'm leaning towards a sponge. I have 3 photos-- top/bottom and one side view. (Note: photos don't capture the crystallization) What do you think it is? Thanks in advance.
  21. Eocene Sponge Identification help.

    Hi everyone! I have been cleaning out, organizing and labeling the mounds of sediment buckets in my garage. Plenty of time over the holiday break to try and get my mind back in to the fossiling mode. I tried at the beginning of this year to get my Friday excursions going again and venture to some quarries, but there are limited areas which the fossil hunter may tread now a days. Then priorities in life too . These buckets of sediment have been waiting for me for many years and months, just waiting for me to take the time to investigate their treasures. I started a few days ago on a few of my Eocene, Castle Hayne Formation, North Carolina buckets. Many bryozoa, crinoid, echinoid and occasional crab claw specimens appeared during my screening and washing. Several species of sponge too. I came across this dandy lil' fella and would like to ask for some assistance in identification. Has that "sponge" look to it and seems to have other characteristics. I did not find it in the NCFC Invert Book or my other Invert books. Any help is greatly appreciated. Best, .
  22. Animal/Mineral/Vegetable?

    I found this "thing" in North Myrtle Beach, SC. It's hard but looks like old sheet insulation. Note the dent. Any idea? Thanks!
  23. Sponge on a stick...

    Hi again, Didn't think I should bother you guys with another sponge, but this is a bit peculiar and I can't find anything about sponges on sticks? This was found in the Kristianstad Basin, Cretaceous period. It is heavily erroded and mineralized, but probably a sponge. It seems to have a circular growth around what seems to be a stick of some sort. They seem proprotional, so I figure they grew together, but they might not be the same spieces? (the stick + the sponge). The images does not make the fossil justice, but it is a very voluminoes sponge with bulges that reminds of glass sponge. The stick is circular in the bottom and more flatt in the top. It might not have reached tremendous heights...? Questions: Would a sponge grow on a stick? Why would a sponge need to reach height if it is not drawing energy from sunlight? How would a sponge like this pump water? I can't find any "sucking holes" Shouldn't a sponge with sticks be more branching? More than one branch? All the best/ Linus
  24. All-- I'm newer than new, but I've been here before and received great help. Will you please help again? I found this approximately 4.5" x 4.5" (11.4 cm x 11.4 cm) piece in a creek bed (Spring Creek; altitude ~700 ft [213 meters] above sea level) in south-central Missouri about 26 miles north of the Arkansas border. (Very near Rockbridge, MO.) I THINK it is either a coral or a sponge and hope I haven't already misidentified it! Thank you for helping this total novice. --Bill
  25. Hi guys! I don't post here often, but I'm a PhD student in geology, currently working on tropical Paleogene palynology. I'm taking an unrelated class on the Permian Basin and I am working on identifying some of the fossils our class saw in Guadalupe Mountains National Park. I'm not a sponge expert, and I was hoping someone on the forum might be able to confirm or correct my identifications. I might make a follow-up post on the non-sponge fossils we saw on the trip. A bit of background, these pictures were taken in the field with a metric scale, the scale has been cropped out of the pictures and a 5 mm scale bar is added. No fossil collecting was allowed on this trip so I won't be able to provide additional images. The fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. The global stage name is actually named after the nearby El Capitan peak. Amblysiphonella? Archaeolithoporella?
