Coral-ID - Weißenegg-formation, Styrian basin, Eastern Alps (Langhian, Miocene)
FranzBernhard posted a topic in Fossil ID
Waiting for Christkind and(!)/or(??) Santa Claus gives me some time putting together this question: The coral in question comes from the Styrian basin (Weißenegg-formation) and is Langhian/Miocene in age (ca. 15 Ma old). It comes from a very small road outcrop, mainly limestones, north of Heimschuh in the Sausal mountains, southern Styria, Austria. Beside massive, sturdy coral colonies like Montastrea, possibly Favites, etc., another colonial coral occurs in this outcrop, that disintegrates easily into individual sticks or pencils, aka corallites: Outcrop situation, field of view ca. 80 cm. It looks really something strange and unusual. These are individual corallites or they are in the stage of branching; the middle one is about 8 cm high. Sometimes you can retrieve parts of colonies. Remarkable is the large diameter of the corallites, up to 2 cm. With the help of some superglue, it was possible to make some polished slabs of these corals (the matrix is a rather soft marl). Note the highly varying diameter of the corallites and the budding. Especially interesting is the specimen to the lower left. Here, some big (about 2 cm diameter!) polygonal corallites are tightly growing together. But I think, its the same as the other ones. A possible genus that comes to my mind is Acanthastrea. This idea is based on the shear size of the corallites. This genus is know from an outcrop a few km away and also from a similar formation of similar age about 100 km away (Mühlendorf, Burgenland, Austria), the species mentioned/described there is A. horrida. But my idea, that these could be also Acanthastrea could be totally wrong, of course... Thanks for your help and Merry Christmas! Franz Bernhard

First picture is from shores of Lake Erie and I'm wondering if anyone can ID what species of horn coral this is. Second picture I'm looking for the same information. Thank you!

Hi last year my moms friend went to Egypt and when she was there she found some fossils for me. This is one of them it’s unknown coral from the cretaceous of Egypt not too far from Cairo. Does anyone know what type or species of coral thanks!

Three bone like 'fossils' found together, any idea what they may be?
tritonpolaris posted a topic in Fossil ID
Hello, I recently found these three items in Custer County Oklahoma where Quaternary mixed with Permian and Cretaceous bedrock can be found. They were all found about 5 feet from each other with items one and two on top of each other. When I hold them they remind me of a terracotta pot in texture and kind of sound like terracotta when you tap on them. I am guessing they are fossilized bone? If it is bone I would love to figure out what it came from but understand that determining exactly what it was from may be difficult. I appreciate any input on what they could be and would also understand if its too difficult to determine. Below is item one, kind of flat.. Maybe a Skull?

Monday morning was dreary here in Central Kentucky. The sky was cloudy grey, and the rain was sputtering off and on. I didn't let that dampen my spirits though. I had planned to go fossil hunting and nothing was going to ruin my day! I grabbed my hunting gear, a cup of coffee, dropped my daughter off at daycare, and headed out. I arrived at the Upper Ordovician (Drakes Formation) spot that I had found this year. The last time I visited this place I didn't have time to really enjoy myself. It was more of a smash and grab. A rush to see if anything was actually there and to grab what I could. This time I was determined to spend more time at my new found hunting grounds. Not even a little wind and rain would stop me. After about a 45 minute drive I arrived at the road cut. The last time I visited, I looked through the scree at the base of the cut and found items that, over time, had washed down from the rain. Many of these pieces didn't fair well with the 5-6 meter drop. After a few minutes of looking at the strata of the cut, I determined that the most fossiliferous layers were at the top 2 meters or so. I decided that I needed to check out the top instead of the bottom. I'm glad I did! After a short walk and hike up the gentlest slope I could find, I made it to the top. This is what I found. A loose layer of dirt (well mud since it was raining...) with coral heads and fragments everywhere! All different shapes and sizes. whole specimens just a few cm across to ones that where half a meter or more.

Moderately heavy rock ( not volcanic) with very rough surface, with interesting inclusions. Found in Osage River valley (an arm of Lake of the Ozarks) in Benton County, MISSOURI ( west central MO). If anyone has an idea what this is, I’ll send more pictures.

I am not sure what this is. Could it be coral or tenticle?

Coral fossil from Cyprus PLiocene deposits, can anyone identify the species?

My boss has a collection of fossils picked out of the Brazos river, TX. Most of his are pet wood/plant but this one perked my interest.

Is this bone or coral? It is lighter in weight than other similar in size pieces found that were definitely bone.

My Coral: both sides, found many years ago hunting in Florida Corals (or more formally, Zoantharia) have mobile larvae that become sessile (fixed to one place) after a few days. They are marine animals related to jelly fish and sea anemones, but lacking a free-swimming (medusoid) stage. They may have first evolved during the Precambrian and are still found living today. Some, like octocorals (the polyp has eight arms), are soft bodied and rarely preserved as fossils, but others secrete a hard calcarous skeleton and are thus important rock-forming organisms. We focus here on the three groups (or orders) of corals that are most frequently found as fossils — Rugosa, Tabulata and Scleractinia.

Two species from the Yorktown Formation along the James River in Virginia that I cannot identify. One a coral (if not genus name, family?) and the other what I presume to be part of a bivalve. Both are very common yet I cannot find them in any references. Any help would be appreciated. Thanks.

I know that Central Texas limestone can weather out into a WIDE variety of shapes and forms and I just assumed this was weathered limestone, cool looking but unremarkable. However, I have seen a couple of pics on the facebook rock groups of coral that looks suspiciously like this. However, I do not see the correct "striations" in mine that coral should have. So is this just a rock or is it coral? I don't believe there is any coral like this in the Cretaceous period, but I do not know, i might be wrong! Back side: A picture of one from the groups: I believe he said his was from New York, and was posibly older than Cretaceous I do not really remember. Similar, not exactly the same, but close enough it made me wonder.

Hey TFF Members! It's been a while since I posted, and I see I have messages I need to reply to as well. I will get back to them ASAP. I have just been ridiculously busy and it's hard to keep up with everything. I just went up to Georgia to hunt for Agatized Coral Geodes! Cris got a saw and we were able to cut what we found in the video as well. I had a great time and we found some really great specimens that looked amazing cut up. Check it out when you get a chance!

Favosites sp. from the Devonian Hungry Hollow member in Arkona, Canada. One of the more interesting corals I've collected, I'm trying to narrow down the species if possible. Any ideas?

Hi guys! Haven't made any posts in a while but as I was going through some finds from Penn Dixie recently I have come across a few more fossils I would like to ID. The first few are what I believe to be Pelycopods but I have no further info on them. 1. Part and Counterpart 2. Part and Counterpart, found in the same piece of shale very close to number 1 3. Smaller one among some horn corals 4. A larger one, this one is thicker than the rest and is very different in texture. I have a few more pictures but I don't have space so I will include them below, Thank you guys for any help, Misha.

North Sulphur River Texas Cretaceous find. Is this coral or a worn Globidens tooth? I'm leaning towards coral. Both are pretty rare finds at NSR so I'm not sure.

This came from San Saba County, Texas; found in fluviatile terrace deposits (Qt). I would love to know more about this fossil. Thank you for your input.

Sorry I haven't been on the forum in a while since I've been working like crazy. After a 71 hour week last week I took a day off. My new job is a driving job around my local area so I make notes of places to revisit to rockhound ( I also do some while on layover time but its hard not to get dirty!). I went back to one today, It is a Bralier Shale (Devonian) exposure. Here's where I need some help. Are the tube things #3 corals or bryozoans? Any id's on the other things would be appreciated. Scale on all is centimeter.

ADMIN NOTE: This was split out from the Fossil of the Month entry thread, as it strayed from the intent of that topic. It was decided that this might be useful as a learning tool. Thanks, Franz. Slow month so far but hopefully not everybody is out shopping for Halloween costumes and are instead taking advantage of the autumn temps to go out and add to their collections. Hoping to see the usual last minute addition of some enviable finds. Atlantic corals are something I know just a bit about (the extant ones anyway). A few years back the reef coral family Mussidae was analyzed using analysis which combined new DNA evidence along with the traditional morphological methods of classifying corals. Former students of a coral reef scientist friend of mine published an important paper resulting in the reclassification of several modern corals. ANN F. BUDD, HIRONOBU FUKAMI, NATHAN D. SMITH, NANCY KNOWLTON, Taxonomic classification of the reef coral family Mussidae (Cnidaria: Anthozoa: Scleractinia), Zoological Journal of the Linnean Society, Volume 166, Issue 3, November 2012, Pages 465–529, https://doi.org/10.1111/j.1096-3642.2012.00855.x The upshot of this as it applies to the genus Montastraea is that it now only contains Montastraea cavernosa, a species with large exerted "vocano-like" polyps which are roughly 5.5-7.5 mm in diameter and contain 36/48 septa. Here is a living Montastraea cavernosa colony: The other three extant species of Atlantic corals formerly in Montastraea were moved to the resurrected genus Orbicella (O. annularis, O. faveolata, and O. franksi). https://en.wikipedia.org/wiki/Orbicella These species (and the various hybrids or intergrates between them) have much smaller polyps (2.1-3.5 mm) with 24-26 septa. This genus is one of the primary reef building corals in deeper fore reefs. Here is an example of a living colony of Orbicella faveolata: I have no idea if taxonomic changes in the modern (extant) corals have any effect on what may be ancestral corals from the Miocene fossil record. I guess we would have to either know an invertebrate paleontologist (which I do) or find some papers online dealing with these Miocene (Badenian) corals that were published since the 2012 revision. If I can find further information, I'll post it here. Cool coral--whatever genus it belongs to currently. Cheers. -Ken

Hello everyone, I recently found this piece along the shores of Lake Erie near Sunset Bay, NY. I'm not sure what I have here and was wondering if anyone might be able to help me identify it. For a little general information, the piece is pale white and features small tubular / stacking formations throughout it. When held in the light, the little stacks sparkle. The piece is just a little over an inch in diameter. Any assistance would be greatly appreciated. - Alex K.

I picked up a few pieces of this stuff at a Devonian site in the Bull River Valley this past August. The tour guides weren't much help, and it's hard to find info about corals if you don't know the terminology very well and maybe there isn't much literature on corals from this site? If I could get the possibilities narrowed down, that would be better than nothing. I just figured it looked distinctive enough that someone might recognize it. Very small corallites, 1mm scale or less. All I know about the site is that it is supposed to be Devonian. Forgot scale on this first piece but the following ones have it. There is at least one other type (maybe two) on this piece as well, toward the right.
