Hello guys I collected this Rugosa coral from the Upper Devonian of Charouine, located in the Ougarta ranges, Algeria. I wonder if someone can help ID the genus and species properly! I appreciate your efforts.

I wonder what we can see in this limestone with a lot of microorganisms displayed together. Some is obviously coral, but there are more things. The rock is from the Upper Ordovician in the Oslo field in Norway. The size is indicated by the distance between the two blue line being 1 cm. You can enlage the picture a little to see more clearly the smaller things.

Hi everyone this is Matt again. Today in the creek I just found a very nice Favosites fossil. Here is a photo:

I found this in eastern Iowa and was unsure if it was coral or a sponge. Anything would be helpful!

I found this in my creek in middle Tennessee and after researching I think it is tabulata coral? Specifically favosite? It's about 3in/7.62cm long and 1.5in/3.81cm thick.

Hi was wondering about these ones. First I think is partial trilobite but not sure. The bone is modern I think but I was wondering if it was cow. Found in a farm field. Thanks for all the great info

Inspired by trip reports by other members on the fossil shells of the Middle Miocene Choptank Formation, especially @I_gotta_rock's report from 2018, over the past several months I have made a couple trips to Matoaka Beach Cabins in Maryland to collect some of the incredible invertebrate material exposed along the cliffs and in that way draw the quizzical looks of other collectors there combing for shark teeth. It is a lot of fun to just park myself along the beach and break down pieces of talus with a screwdriver to uncover hundreds, if not thousands, of shells. Unfortunately the shells are incredibly fragile so a lot of effort was taken to wrap the fossils in aluminum foil on the beach and to meticulously expose them with dental tools and toothbrushes and consolidate them with glue at home. Despite my precautions, many shells were lost, both on the beach and at home. I found everything along the beach and in talus falls, except for the large piece of the sand dollar Abertella aberti. On my latest trip to the Chesapeake Bay a man collecting shells along the beach asked me to identify a few things that he had found washed in by the tide. He asked if this fossil was a piece of turtle shell and when I told him that it was instead a piece of sand dollar and that it is rare to find a piece that large, he asked me if I wanted to have it. I of course graciously accepted his offer. I offered a couple of other fossils later on, but he seemed satisfied with what he had already found. There are so many fossil shells to be found along the cliffs of the Chesapeake Bay so I will try not to bore you with all of my finds. I think the gastropods are really cool so I have included all of my gastropod finds. Without further ado, here are my favorite finds: The only vertebrate fossil I found was this Aetobatus sp. ray tooth that was found lodged inside the opening of an Ecphora shell What is a post about Miocene shell collecting without a big Balanus concavus barnacle. This one was found in about six inches of water at low tide on my first trip. About the same time I found the barnacle I found this awesome chunk of Astrhelia palmata coral, which even has some bryozoan on it A couple crab claws found while searching the excess matrix compacted in the shells The aforementioned piece of the sand dollar Abertella aberti Now for the shells. First off are a couple Chesapecten nefrens. I love to find ones that have barnacles still on them. This was my largest one, measuring about 6 inches across. I found one that had both valves, but sadly one of the ears is missing Chesacardium laqueatum blackwelderi Atrina harrisii Stewartia anodonta Dosinia acetabulum blackwelderi Timothynus subvexa Ostrea carolinensis The largest shell found along the beach is the geoduck clam Panopea americana You can also find another species - Panopea goldfussi. I love how this one preserved in life position. All I had to do was dig some of the matrix out and glue the rest in. Glossus marylandica Mercenaria cuneata While finding the big gastropods was the real draw, I also really liked finding the tiny gastropods, which I only found at home after screening extra matrix or breaking extra matrix down by hand. The first of the tiny snails to show off are these three species of Calliostoma. From left to right is Calliostoma aphelium, Calliostoma philanthropus, and an unknown species of Calliostoma. Perhaps my favorite tiny gastropod - the predatory murex snail Typhis acuticosta I believe this one is Surcula sp. Perhaps the smallest fossil I have ever found- Teinostoma calvertense. Can you see it in the photo on the right? Terebra sp. Cymatosyrinx limatula Mariadrillia parvoidea Nassarius peralta Nassarius peraltoides Neverita duplicata The moon snail Euspira heros is by far the most common gastropod. I found a dozen of different sizes. Here are only a few. Mariacolpus octonaria Turritella subvariabilis Crucibulum costatum Crucibulum multilineatum Scaphella virginiana I love this juvenile Busycotypus rugosum whelk shell Spinifulgur spiniger oslowensis

Hello! I went fossil hunting with my brother and found a tooth shaped cone! We live in rock county of Luverne Minnesota, about 30 minutes away from Sioux Falls South Dakota. We went to a local river nearby that has a sandy riverbank with lots of different kinds of rocks. We have found a lot of small fossils of shells and some coral-like shapes. I found it near the water where it likely washed up. I assumed it was maybe a coral piece because I don’t know anything about teeth. But Google shows a lot of similar images from both teeth and some coral. I’m just not sure how to go about narrowing down what it is. It has distinct circular rings (like a tree) on the top. The pointy end appears to be broken or chipped. It appears to be just about 3 centimeters long. As much as we both want it to be a cool tooth or something we’re just assuming it’s coral, we really have no idea! Thanks for any help or advice! I can answer more questions and take more pictures if necessary!

Hi I have two questions. Both are southeast Michigan finds. The first is a phallic fossil coral or something. Not sure what. The other is a deer bone with unusual growth on it. Cancer? Any help would be appreciated.

I found this lovely rock at the Monroe reservoir on Monday. I believe it's a petosky stone, but maybe I'm wrong. I'm also wondering if I should try to polish it or anything or if it would be best left alone.

I found a rugose coral today and I also found another piece that looks similar but doesn’t have the rugose shape. Can you tell me if it is a rugose coral piece as well of possibly something different. Also found a piece of baculite not too far away. These were found in southern Alberta in the Bearpaw Formation I believe. The pictures below are of the rugose coral I found near by.

I found these 5/10/21 around Elko Nevada Nevada in an area rich with coral and Brachiopods. Any help identifying theses so appreciated! Ty!

So I am driving on RT. 47 which leads to Vernonia and Mist, Oregon and a road cut that looks very similar to the Keasey locations I have been picking talus and for the first time it appears dry (seems to be a seep at the the top). In Oregon unless on private or in special circumstances BLM land you can not dig, you have to surface troll. I found a safe parking space and then crossed the road to enter the ditch. Once again close to traffic but people on this somewhat used road either slowed or pulled over, except for the truck who stopped and gave me directions to "a secret" place:), now that's cool. I had stopped here during winter but it was really wet and I left after finding a mollusc taking an image so I had the GPS. This day it was very different quite a few concretions had fallen out of the formation. These are very, very had carbonate concretions. So I decided to pickup 3 or 4 and see what I could find. There are lots of sociological items on this piece. However the object of interest in the focus of these images. I have an assumption (I'll post mine after a day or two) of what this is due to the formation (if I am right and the location of this outcrop in relationship to Vernonia and Mist, Oregon). That being said what is your best guess?

Hello! one of my coworkers brought in this fossil since they knew I was interested in that sorta thing and when I first saw it my mind went to coral but they said it was from California and was told it was a Mammoth molar, so I had to change my theory. While I know it is not a Mammoth molar it definitely has a tooth like structure, and in my opinion, could look like a heavily worn down Mastodon molar but I wanted someone who is an expert in this field/ knows more information than me to help with the identification. I didn't get to measure it exactly but my rough estimate was around 13cm

I am wondering what fossils you can see in these rocks. they are all carboniferous limestone (prehaps not the red/brown one). I can see Bivalves, coral, crinoids, brachiopods (I think), And nothing else. Why aren't there other carboniferous life. (I understand soft parts go) These rocks are packed with fossils, what can a real paleotologist see?

Hi everyone this is Matt again. Take a look at this coral fossil that is made of crystals that I found in the creek today. here are some photos :

More Lake Michigan - Long Beach, IN finds. #1 - just a rock? #3,5 - horn corals? #4 - favosite? #8,9 - more coral? Sorry about the photo quality/quarter as a size reference. It was the best I could do for now. Thanks for your input

When I found this small piece - I was sure it is a brachiopod... But now after looking on many other things, I am sure it is not a brachiopod. I am thinking about the base of a coral. Please help to identify it. This should be Ordovician. N.1 N.2 N.3 N.4 N.5 N.6 N.7

Hi I have syringopora coral that I want to make more visible. Right now most of it is buried in limestone. I don't want to remove all matrix, just make "tubes" more visible and appealing. Will soaking it in white vinegar do the job?

Hi I found this fossil in gravel pit near Zgierz, Łódzkie, Poland. I think it's syringopora coral, but I'm not sure. I think it's worth noting that fossils from this area are glacial erratics.

Hi all I hope you all are safe and well. Please can I have some help on this coral ID. If was found about 12 years ago . Somewhere In the Yorkshire Dales/ Pennie Way . Sorry but that’s the best location I have until MrsR looks at a map. I can do better pictures tomorrow if required. @TqB any ideas pal. thanks for your help Bobby
