All, I went fossil hunting at a new site a little north of downtown Nashville and hit paydirt with these large pieces of rock; they are absolutely packed full of rugose coral

Hopefully this will be quick and easy for those who have the knowledge. I was meandering in the hills and came across some horn corals. I am used to calling the smaller one on the left a horn coral. I am presuming the one on the right also a horn coral. Would someone kindly provide sufficient naming to each so I can do some offline research and reading? Apologies for fuzzy pic. Camera seemed to only want to focus on the backdrop material.

I'm really curious about this odd looking Grewingkia I found yesterday in the gravel beds of the Whitewater River in Franklin County Indiana. I've found quite a few, all clean of any substrate, many on top of the ground. Yesterday I found this one just about 10" below the surface of the gravel. Most of the horn coral has linear lines, but this one seems to be segmented unlike the others. Is it older or what causes the difference in this on compared to the others? I appreciate all of your help!

Cool Michigan Horn Coral/Personal Collection
The007Fossil posted a topic in General Fossil Discussion
The big horn coral embedded in the rock is about 1.5 inches long, for scale. I really like the colors! Anyone have any idea what species it could be? Whenever I find em' I just call em' "horn corals", but if you ask me, they look more like barnacles or something (even if they're unrelated -__-) Good hunting! -
My wife and I are on a short trip through south eastern New York State, in the Catskill Mountain region. We had a more adventurous trip in mind but after some recent car trouble we didn't feel quite as adventurous as we did a week ago. We stopped today at a site on Schoharie Creek, a bit south of Gilboa. The heat and humidity kept us from spending more than a half hour at the site today, but we plan on going back tomorrow morning when it will be somewhat cooler. The river tumbled stones were mostly eroded, and I didn't bring my hammer down to the beach crowded with swimmers, but we did make one find worthy of bringing back to the motel. Leila usually makes the best finds when we're just scanning the ground, and she came up with this worn but still attractive horn coral. I love the way it's still attached to the matrix. It almost looks like it's been prepped: The same rock also shows off some nice specimens of what appear to be tube worms. Despite the heat we're enjoying our trip so far, and we're very happy with our motel except for one disturbing problem. Clinging to the door inside our lovely room is a five-foot-long mirror, and I am periodically startled by the strange old man peering at me. What's he doing in my room?! Mike

Hey, My sister and I found this rock that we thought looked a lot like a claw or a tooth. We found it in Norway in a lake, because of the drought the water was a lot lower than usual, so the place we found it would normally be underwater. It's not too far from the ocean either. I really don't know much about any of this, so I'm sorry that I'm not including too much information. (And sorry about the tags, I had no idea what to put there) I hope someone is able to help us, thank you

When I first found this fossil I had no idea what it was, but after only two days on this board I'm pretty sure it's horn coral. Learning quickly! Just looking for a positive ID, since I'm still very new and could certainly be wrong. Like the others, probably found on the Michigan/Indiana border. This is the last one for today. Thank you guys for all the help!

I found all these specimens on the west side of the road cut. I believe those are eyes in the middle. All these specimens were found in Trammel Fossil Park in Sharonville, Ohio, with the exception of the two in the column on the right. They were from the St. Leon road cut. This tear-dropped shape bryozoan is, I believe, Homotrypella.

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

Hello everyone! This past Saturday, Viola and I braved the cold to do some fossil collecting in the south pit of Hungry Hollow near Arkona, Ontario (Mid-Devonian). When I got home and washed up my specimens, I saw something interesting on one of the horn corals - I think it's a brachiopod - am I right? And does anyone know its identity? Thanks in advance for your help! Monica

One of my students found this near Jacobia Texas and would like it identified if possible. I have more pictures of it on the forum's Facebook page.

I should preface this post by saying that the Paleozoic, marine ecosystems, and invertebrates are not generally my primary expertise, so I apologize if I am wildly off base or asking stupid questions. Sadly, I did not find these specimens myself, and so I do not have any particularly useful information on age or location. They were left in a desk drawer along with a collection of other invertebrate fossils, most (if not all) of which are Paleozoic in age. I have several different rugose coral species, and I would love to know if anyone can refine that identification further. I thought the colonial rugose coral might be an Eridophyllum species, but I would not bet much on my identification. The third is truthfully in terrible condition and I doubt there is much to say about it, but I thought I would see. Here are the pictures. Thank you in advance for your time and input.

Hello, all! So I am cleaning out my workshop to make room for a lot of new material coming in and to prepare for the upcoming season. I have wayyyyyy too much Penn Dixie material. I have, at this point, committed all of my complete bugs away. But I still have quite literally, TONS, of other material. What I am offering is Edlredgeops rana partials, this includes entire prepped bugs that are missing cephalons, stand alone cephalons, pygidiums, large but broken cephalons, half bugs, etc. (Please note, I am not offering any of these as complete. There is the real chance that some of the unprepped material COULD be complete, but I am not offering them as such. I also have Greenops pygidiums and partials, beat up examples with broken cephalons, etc. I also have a few Bellacartwrightia pygidiums laying around, and perhaps a few broken and partials of them as well. I also have massive quantities of hash plates from the Bay View coral layer, brachipods (Mucrospirifer, Pseudoatrypa, Rhipidomella, Spinatrypa), Spyroceras cephalopod partials, rugose and tablulate corals, clams, and other random bits. I am interested in trading for similar material from other locales. I am not expecting anyone to offer up prime specimens for any of this material, but I would love anyone else's throw-aways that include vertebrate material, plants, small fish, and the like. I am also considering minerals and gems. (Again, throw-aways are all I'm looking for, quantity beats quality on this one.) I will cover shipping domestically in the US, but can't really afford to ship out a ton of international packages this month. (I will still do international, we just might have to work something out.) If anyone is interested, please message me! I want this stuff gone as quickly as possible, it's getting to the point where I can't walk in my workshop anymore! If you let me know what you're interested in I will take photos of some examples, but it would take me a full weekend at least to photograph everything that I have available. This is perfect for anyone wanting to practice prepping as the Windom shale that most of these bits are in is relatively easy to work and there are lots of attractive pieces that will look very nice prepped, just aren't worth the time and effort for me at this point. Cheers!

What is the net like pattern that sticks-out on the inside and outside of a silicified Pennsylvanian horn coral from NW of Payson, Arizona? Could it be an epibont-sponge? Could it be silica that filled cracks in part of the coral that was not silicified and eroded away? The coral opening is about 2.5 inches across.

Polished Horn Coral fossils SITE LOCATION: Western Sahara, Morocco TIME PERIOD: Devonian age (358-416 million years ago) Data: Horn Corals are from the extinct order of corals called Rugosa. Rugose means wrinkled. The outside of these corals have a wrinkled appearance. Horn Coral grows in a long cone shape like a bull’s horn. The fossil is the skeleton of the coral animal or polyp. They built these cone shaped structures from calcium carbonate that came from the ocean water. The animal lived at the top of the cone. As the animal got bigger it added more material to the cone. Each layer was a little bigger than the previous one. All corals belong to the phylum of animals called cnidaria. They are related to jellyfish which are also cnidaria. While modern corals are colonial the now extinct horn corals could be colonial or solitary animals. They had many tentacles sticking out to gather food. The tentacles gave them a flower like appearance. The oldest of the Rugosa corals are found in rocks from the Ordovician Period. Many species evolved during the Paleozoic Era. As a group they flourished until the Permian Period when they became extinct along with most living things during the Great Permian Extinction. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: †Rugosa -

A friend of mine found an interesting fossil a Keifer Creek in St.Louis Missouri. He was unsure of what it was but I assumed that it was a horn coral or perhaps a vertically split brachiopod. I am not the best at identifying fossils so I was hoping someone on the forum with more experience could take a look at it. The fossil being referred to is in the middle of the stone.

After making a stop at the Anna Roadcut, I drove about 15 minutes to Vienna, Illinois where there is a roadcut at the entrance to Interstate 24. This rock is supposed to Be Mississippian Menard Limestone. At this location I also found some nice hash plates, my biggest blastoid of the day, Horn coral, Archimedes’ screw, bryozoan and brachiopods.

Checked out a spot I hadn't been back to since moving back. Found several lenses of fossils but the siltstone is so fragile that it crumbles to nothing. There is one layer of harder stone but it is impossible to climb up to. This chunk had tumbled down and gave me my find for the day - a nicely partially weathered out solitary horn coral. Devonian, Brallier Formation from near Roaring Spring PA.

Found this horn coral on Trilobite Ridge in the NW corner of NJ this past weekend. The 2nd picture is the back side of rock. Is it possible to identify the species with these pictures? Thanks, Mike

I like to look for rocks in Tennessee (almost the Kentucky Border). This one I picked up thinking it was horn coral, but I do not see the normal markings on horn coral. I have never seen the "curl" on the end of any rock look this. Possible shell? Curious what everyone thought.
