Hello everyone, This will be my final ID topic for a while as I am trying to get some labels for a few fossils in my collection. Here are two fossils of marine animals, the first I believe is a bryozoan, I have no idea of the location or age of either but this piece has a strong resemblance to the devonian Fistuliramus and Eridotrypella from Morocco. The second is a very white and chalky horn coral, I am guessing that it is from somewhere in the US as the person I got it from mostly has US fossils. Does anyone recognize the fossilization on this piece? I am trying to identify where it is from.

Good morning all! Well, I couldn't find my Unklesbay fossils of MIssouri, so bought another on online. In it, the object I thought was a horn coral ( I posted this earlier) looks pretty similar to what he depicts as Cystophyllum. Thoughts? Does this seem more reasonable? Thanks! Bone

Back in April 2017 I posted pics of what I thought was a unique bryozoan encrusted horn coral.... Since then I have come across more while collecting in SW Ohio that I'd like to share. And, yes, the prep can be extensive. The first one, there is no real top/bottom or side view. It is 7 cm across x 10 cm "tall" This one is 4.5 cm across x 4.5 cm "tall". I believe the bryozoan on the following is Constellaria florida This one is 5.5 cm across and 6 cm "tall" This last one is my favorite. I finished prepping it in early March. I think the layering of the bryozoan is amazing. It is 7 cm across x 9 cm "tall" x 4 cm "deep". The horn coral is broken.

Here is my next one that, as best I can tell is mineralized/geode-type horn coral? Also found in the St. Louis area when I was a kid. Am I correct? thanks!! Bone

Hello everyone. As usual, I need your help with one of my finds. It seems this small rugose coral has a buddy. At first I thought the the tiny "bump" was just a bit of debris sitting on top of the coral. But now that it's enlarged, it looks to me somewhat similar to a crinoid. I'm not really sure though, I've never seen a crinoid preserved anything like this. Surely it's not part of the horn coral itself, or is it? Thanks to all for your input. Detail:

I picked up this jasper for its banding. Only later, when checking the rock through my hand lense did I discover what I think are a bunch of little rugose colonial corallites at the top and bottom of this rock. If these are indeed corals, all but one lack most detail in the center. If septa are faintly visible, they look differently preserved than on any of my other coral specimens. Mostly it's just circle after circle here, and areas full of "pores". Now that I'm looking at them on my larger screen, the "pores" themselves seem to be corallites - microscopic ones. The black dots are in the center of honeycomb like shapes. I'm confused now, are these the fossilized remains of one or two type of corals, or maybe a colonial coral and a bryozoan? Sorry about the bad quality and distortion of the pictures taken through a microscope lens on my phone. Please help me ID these tiny hurricane look-alikes. As always, thanks in advance. Here a couple of them in various states of preservation. Lots of them have a vug where the center of the corallite would be. Here the circles look like growth rings and in some areas the "pores" are clearly visible. #1: This one is the only one with detail in the center. Septa? #2: a vug at the center seems all that's left here. #3: Just pores in the center, and in between the circles, maybe the faintest lines that could have been septa? #4: Area in between corals, with faintly visible honeycomb shapes: Detail of the above: Another area in between, looking somewhat different again:

Removing matrix from the Brachiopod. "Boring!" plus Crinoids. X-acto knife and fiberglass brush. 5.0 cm x 4.7 cm. Brachiopod. 2.3 cm was thick and covered most of it.

Hello everyone, requesting help with a fossil ID. New member and very new to fossils, daughter has shown lots of interest in fossils and wants to be a paleontologist for about a year. I try and continue to encourage it and we go to different creek beds here in Kentucky along the Tennessee boarder. We typically find lots of brachiopods but nothing like these. I think it looks like limpets, but I can’t find anything similar to it online. The University of Kentucky website had some similar sketches of horn coral, but I am not sure. Any advice or suggestions would be greatly appreciated. Info: small, about the size of a quarter found on the banks a larger sized stream in southern Kentucky usually find lots of brachiopods in the area

Hello. These two specimens were discovered in Southern Indiana in a wooded area with a nearby spring. A tentative ID was given as a Rugosa (horn) coral but someone else thought it could be petrified wood. If it is a horn coral then are these two pieces from a mid-section hence whey the conical property is not apparent? I appreciate any and all feedback.

Hello everyone! I'm here once again to ask for some identification help as I continue to work on my fossil area display. Today I have a few items from Penn Dixie (Hamburg, NY, mid-Devonian) for you to look at. But before I show the photos, I was wondering about the formation that we find fossils in at Penn Dixie - is it all Moscow Formation? Okay, now on to the photos... Specimen #1: A Platyceras gastropod, but I'm not sure of the species: Specimen #2: A horn coral on the same rock as the Platyceras - is it Stereolasma rectum or Amplexiphylum hamiltoniae? Specimen #3: I've posted this one before, asking if it was a goniatite or a gastropod, but I'm starting to think it's a gastropod with some of the middle missing - perhaps Naticonema lineata or Euomphalus laxus? Specimen #4: A brachiopod and horn coral on the same rock as the goniatite/gastropod specimen - is the brachiopod Athyris spiriferoides? And is the horn coral Stereolasma rectum or Amplexiphylum hamiltoniae? Specimen #5: An unknown piece of something on the same rock as the goniatite/gastropod and the brachiopod - any ideas? Thanks in advance! Monica

I took my family across the river to Clarksville Indiana today to visit The Falls of the Ohio State Park. It was very hot with a high in the 90s, but we had a good time walking the Devonian fossil beds and visiting the Interpretive Center . The river was down enough to get onto the upper limestone beds, but the lower beds were still underwater. They are typically exposed during the months of September and October and occasionally in the summer when there is little rain (not this year!). The river is at 20 ft right now. The lower beds become dry around the 13.5 ft mark. Their official website has a page that monitors the river levels and tells you when certain areas and strata are exposed. I suggest checking that out before making the trip to visit the park. https://www.fallsoftheohio.org/current-ohio-river-conditions/ The Interpretive Center houses the main indoor exhibit, gift shop, a river viewing room, and bird/wildlife viewing room, along with friendly staff. The main exhibit has fossils and interactive areas for the kids. Not only are there fossil on display, but also sections regarding the Native Americans that lived in the area, the current wildlife, and information regarding the Lewis and Clark expedition. A piece of fossilized wood just outside of the center on the backside by the parking lot. It is roughly 4 feet in length and 2 feet wide. When you walk into the main foyer of the Interpretive Center this boulder is on display. It is about a meter across and half as thick. I don't want to spoil the trip for everyone so I'm just going to post some pictures of a few of my favorite pieces. I thought this was interesting. It's labeled as orange chert, which I assume it is, but it also has a horn coral right in the middle of it. A sampling of the fauna found in the fossil record here. There was also a small exhibit on mammoths as evidence of a few have been found in the surrounding area. Presumably crossing the Falls to get to the salt licks in Kentucky. This was a comparison of a mammoth and mastadon tooth. The interior exhibit is nice, but for me the best part of the Falls of the Ohio is outside. Its the fossil beds that you can walk on and explore. I've been here a few times and find something new each time I come. Remember folks, it's against the law to collect here. Leave the fossils alone for others to enjoy! No matter how tempting... . If you just have to collect something, the park usually has a couple of dump truck loads of material near the back of the parking lot that they allow you to search through. Seriously. Here are some of the fossils that me and the family found while walking around the fossil beds. A word of caution, if you want to get to certain areas there is some climbing that you must do. A lot of the strata has fissures or large boulders that must be climbed, or walked around to move farther down the coast. This is on the fossil beds themselves. You can stay higher on the slope and circumvent a lot of the really strenuous stuff, but the fossils are not as good the higher up you go. Here are a some of the more impressive horn coral that I found. They actually call these larger ones "tusk coral" because the are so large. I'm not certain what these coral are, but Siphonophrentis and Cystiphylloides are common here. I know a hand isn't the best for scale, but it's all I had at the time. lol From the tip of my index finger to where my thumb connects is just over 5 inches. Some mainly brachiopod hash plates. A large favosites. Crinoids Lace Bryozoan This was my favorite find. A large colonial coral. It is over a meter in diameter. What is commonly called a Pipe Organ Coral. Eridophyllum I think that is all for now. It was a great day of discovery and fun with the family. If you are in the area and have a couple of extra hours, I highly recommend you stop by and check out the sights for yourself. You won't be disappointed. Just remember to check the river water levels and be ready for a little exercise!

This year I pulled the trigger on heading to Penn Dixie for the Dig With the Experts weekend! Definitely would highly recommend . I drove up from Boston to the Buffalo area on Thursday and spent the day Friday digging with @Malcolmt and @JamesAndTheFossilPeach. It was a blast! Thanks again guys for giving me a lay of the land. Credit to @JamesAndTheFossilPeach for the find of the day with a giant Eldredgeops (pic below). Saturday and Sunday were spent looking for trilobites in the roped off Dig With the Experts section of excavated shale with some success. Monday I drove back to Boston, and stopped to stretch my legs in Glenerie, NY to walk a stretch of road looking for Devonian brachiopods and gastropods. Got a couple! All in all, a great trip... although I'm nice and sore . Here are my takeaways from the weekend. I tried to get a bit of the entire Penn Dixie Ecosystem keeping at least one of everything and as many trilobites as I could find. I wish I took more pictures Saturday and Sunday, but I was too busy splitting shale . Cheers, Barret

I found this odd horn coral at the Lost Creek Dam site near Jacksboro, Texas. It's Upper Pennsylvanian, Graham formation, Finis Shale member. The horizontal wrinkling seems very organized, looking more like the ornamentation on a conulariid or some orthoconic cephalopods and the presence of dissepiments limit the possibilities some. The bottom was already broken off so I sanded it flat and polished it a bit for a look at the septal pattern but still can't seem to place it in it's proper niche. Dibunophyllum valeriae has been suggested and Lophamplexus sp. but I'm not convinced mostly because of the horizontal patterning.

Fossil hunt at St Leon Indiana today. One inch square for scale. 8 Flexicalymene. One so small I can't even believe I saw it. Some mini brachiopods, some small horn coral and some gastropods.

Hi everyone this is matt again today in the creek I found this cool coral in the creek on 28 mile creek near 28th creek Rd. between Kennedy and ellington here are 3 photos

Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.

Hey guys this coral keeps drawing my attention. We have hundreds of horn corals and pretty sure this is one, but it looks different than the others? Do you think it just preserved differently or could it be a less common type of solitary rugose coral? Any thoughts appreciated and thanks for looking!

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.
