Can anyone tell me whether or not this is a type of coral? I found it in my yard yesterday. (Middle Tennessee, Mississippian, St. Louis Limestone & Warsaw Limestone)

Today was a Pleurodictyum coral day The largest specimen is 116mm x 96mm, the biggest I have ever found!! Finding one of these extra large Pleurodictyums in a day makes the trip. The pictures of the large Pleurodictyum with the smaller size Pleurodictyum displays the huge size difference between a normal sized Pleurodictyum (35mm x 21mm) and my GIANT. Thanks

Hello, I'm trying to find out what this is. can anyone help? Thx

Greetings. I have a lot of photos I’d like to share and get some feedback on, assuming there is not a unanimous agreement that the specimens you see in this photo are purely Geological in origin... I found them, and many more, within the geographical boundaries of a Jurassic age rock formation in Northern California that is listed primarily as meta volcanic rocks. Considering that information, please tell me if you thinking I’m barking up an imaginary tree here... If you are uncertain, let me know, and I will post more pictures... Thanks for your time! -Quinn

Not exactly sure what this is (not a paleontologist- or even a collector as my username suggests). I was wondering if it was coral or fossilized honeycomb or something entirely different. Any help would be appreciated.

Found this rock and am unsure what it is. It is heavy for its size and vaguely resembles a few different rock types i have searched for, but i have yet to find anything definitive as to what it is. Hoping someone on this forum could potentially identify this one. 1.956 lbs/887 g

Hello there! I was able to visit Hungry Hollow's South Pit (near Arkona, Ontario, Canada - age is mid-Devonian) yesterday - boy was it hot!!! Viola and I spent three hours surface-collecting before we decided to call it quits and head to our air-conditioned car. We found our usual stuff, but I'd like your input on the following two items: Item #1 front and back: a type of Favosites coral - perhaps placenta? It's a lot flatter than my other Favosites finds, and you can even see what I think are some crinoid holdfasts on top, and an echinoderm plate (perhaps from a crinoid calyx?) on the back!!! Item #2 front and back: I have NO idea whatsoever!!! It's smooth, and I can't see evidence of holes/pores, but it is kind of hilly - what do you think? Thanks in advance for your help!!! Monica

Happy Labor Day Weekend everyone! I found this awesome piece on a beach in SW Florida. When I held it to the light....Wow what an awesome amber color with black specs and bubbles inside it. Two properties of amber but not commonly found in Florida though. It is found in Arkansas so here's my theory: It flowed down the Mississippi River into the Gulf of Mexico and washed up on the beach in Florida, Lol. Doesn't look like any coral I've ever found either. Could it be amber or melted glass? I appreciate all replies! Thank You!

An acquaintance I was in school with many years ago in Jasper, Alberta still lives there and is an avid hiker, outdoorsman (woman). She never stops and her frequent forays along the trails and not-so-trails in Jasper National Park have rewarded her with unequaled memories. This is a photo she took of a large chunk of coral twice the size of her hiking boot as she was hiking in the Opal Hills in the Medicine Lake area of Jasper National Park. She isn't allowed to remove anything so there it sits, awaiting the next intrepid adventurer to follow her path. Beautiful.

Good morning! Found this fairly pronounced coral on a jog this morning. I'll never know really where it came from since central Indiana is not known for any level of fossils due to glaciers but I'm assuming this was transported from southern Indiana or Ohio. It matches a coral from the Ordovician period timeline.... I just can't nail down what kind. I'm for sure going to leave it in the stone. I think it looks pretty sweet with how it is housed. .... my wife hates how whenever I come home from anywhere I have a new find.

What is this? found in Emerald Isle NC. Is 4-5 inches across.

Coral (4) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
...and the fourth (and hopefully last for some time) coral question from the Campanian of St. Bartholomä, Styria, Austria. In this thread I present two different specimens, which I think belong to the same genus: Cycloria or Orbignygyra (according to the papers of Baron-Szabo, 2003, 2014). They are maeandroid, colonial corals. In this first post, two polished slabs of the same specimen are presented. They are about 2 mm apart. The corallites are not very well preserved, but in some spots, some detail is discernible. The "better", less recrystallized side is intergrown with the usual fossiliferous limestone (which contains another small coral colony...).

Coral (3) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
Hello, and here is the next (third) coral from the Campanian of St. Bartholomä, Styria, Austria. First photo: Its the largest specimen I have found so fas. The colony is about 20 cm high and is weighing ca. 4.2 kg. Not much to see, photo just for reference. The grey x indicates the location of the second photo. Second photo: On some parts of the colony, individual corallites are clearly visible. Natural surface, nothing done to it. I have also cut off a piece to make a polished slab. Just about 13 mm below the surface of the colony, the coralites are mostly recrystallized (thats a usual case) Third photo: So I have slightly ground and polished the surface of the cut-off piece, with a somewhat better result, showing a few nice corallites. But I am at a loss with this one, I am recognizing the prominent and thick costae, which let me to the consclusion that it could be belong to Nefocoenia/Neocoenia/Placocoenia/Neocoeniopsis (according to the papers of Baron-Szabo (2003, 2014)). But I can not go any further... Any help is gratefully acknowledged! Thank you! Franz Bernhard

Hi Everyone, Found some fossils of what appear to be coral but would just like to get some clarification. Both pieces where found on the Murrumbidgee river near Wee Jasper, NSW. The first specimen has a piece of what I'm assuming is Horn coral but there is another impression next to it that looks like it might be something as well. It is round, 30mm in diameter and textured like a sponge. The second, I'm not really sure, but it may be coral? There are two roughly textured patterns, round, one bigger than the other. First one (smaller) is 35mm radius and second is 65mm radius Any help would be appreciated. Thanks very much, Jed

Hi Everyone! I found this on the Murrumbidgee river near Wee Jasper NSW. Was found near other shell/mollusk fossils (pic also attached).

Hi, I found this on the beach CW Florida. It is brittle, thin and very light but does not float. It's full of aeration holes so I'm guessing it's a type of sponge? 2 photos of front and back. Any help appreciated.

Coral (2) from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
Hello, here is the next (second) coral from the Campanian of St. Bartholomä, Styria, Austria. Not much was visible at the outside (I did not even notice it as coral colony!), but on sectioning, the specimen reveald its beauty. Unfortunately, he contrast is rather low. The two polished sections are about 35 mm apart, the first seems to be near the surface of the colony (with a Lithophaga?). The closest match I can find in Baron-Szabo (2014) is Barysmilia irregularis (Reuss, 1854). Three polished surfaces from this work are attached, scale bars are 5.5, 9.5 and 11 mm, respectively. They are all from the upper Santonian of Neffgraben, Gosau, Austria. Thank you very much for looking and for your help! Franz Bernhard

Can someone please help me out here? I'm new to all of this and my friend is asking me about this fossil he stumbled upon today in Ohio. I've been researching other posts but I'm not 100% on what I'm looking at here. Thank you!

Weathered out of the limestone cliffs at Torquay in Victoria. Not sure what it is ?? Does anyone have an idea ?

Not sure what this is, but my first thought was fossil coral. Can anyone help? I don't remember where I found it.

Good morning, all. Here's a few I've been working on today. Found in sw florida, I think I'm in part of the Tamiami formation. Anyway, I think the little snail is possibly Nassarivus Quadredentatus, but not sure. The large grey I think might be Nodipecten, also not positive. The ones that look like little elephant feet I'm pretty sure are a type of coral, but I can't find a match so I could be wrong. The little "toothed" thing I'm thinking is a steinkern, but would like to know for sure, and from what type of critter. Is the button a sponge? And then there's the wormy looking thing, or shell rim? There are 6 objects shown, shots with multiple angles are grouped together. Any help would totally be appreciated!

Going through the stuff in my bucket that had dried out from my last trip, found more stuff that I can only guess what they might be. The first three are of a tiny disc with holes along the periphery. The next two are of three pieces of a flat discoid "rock", that was more fragile than i thought, looks like from something alive. Last two seem too light for bone, so I'm guessing sponges? Probably some of you will know (penny = 0.75 inches or 19 mm in diameter): Thanks!

Coral from the Campanian St. Bartholomä formation, Styria, Austria (Gosau group, Eastern Alps)
FranzBernhard posted a topic in Fossil ID
Hello, some of you may have noticed my rudist posts from the Gosau basin of Kainach - St. Bartholomä, Styria, Austria. Beside rudists, there are also other fossils, but they are much rarer. During my hunting trips in the Campanian St. Bartholomä formation, I have found ca. 300 rudist specimens (hippuritidae and radiolitidae), but only 12 coral colonies, including two imprints, and no individual coral. I would like to show you one of these coral colonies and would like to ask you for your opinion. I will start with the simplest one. In the literature, only one coral species is described and two others are mentioned (without description) from St. Bartholomä. No pictures are published of any of these three coral species. Here is the only existing description of a coral from this formation (Schmidt, 1908): „Ein halbkugeliger Knollen von 5 cm Durchmesser aus der oberen Hippuritenbank von Kalchberg. Auf einem Anschliff sieht man in der Mitte ein Feld, wo die Kelche senkrecht stehen, am Rand sind sie dem Schliff parallel. … Die Kelche haben einen Durchmesser von 1-1.2 mm. An den Septen sind zwei Zyklen zu je acht Stück vorhanden. Das Säulchen ist punktförmig. Sehr schön ist das Cönenchym, aus unregelmäßig angeordneten Kalzifikationszentren bestehen, ausgebildet." "Half-spherical colonie with 5 cm diameter. ... The corallites have a diameter of 1-1.2 mm. There are 2 septal cycles with 8 septa each. The columella is point-like." He identified this coral as : Astrocoenia orbignyana Milne Edwards & Haime, 1848 According to Baron-Szabo (2014), this is today: Actinastrea orbignyi (Milne Edwards & Haime, 1848) The first two pictures are this species, figured in Baron-Szabo (2014). First scale bar is 10 mm, second one 3 mm. Specimen is from Gosau-Rusbach, Austria. The third picture is my specimen from St. Bartholomä. Its very rough at the outside, but not so bad preserved inside. Sorry, I can not make a better picture. I think it comes close to the description and pictures of Actinastrea orbignyi. What do you think? Thank you very much for your opinion! Franz Bernhard Literature: Baron-Szabo, R. Ch.

I was hiking in Utah and found these. I think they are corals.
