I am currently going through some of the fossils I bought when I was a kid. The fossils I am looking to potentially have ID’d are a few fish fossils that I bought from a couple museum gift shops. For this reason, I do not have much info on them which I realize could hurt my chances of getting them ID’d. I thought I would give it a shot and see if anyone recognized these fish. 1. Fish from Brazil during the Cretaceous 2. Fish of unknown location and age 3. Fish of unknown location and age

Found possible bone after Cracking open limestone concretions! From Missouri
Samurai posted a topic in Fossil ID
Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation I usually collect a few limestone concretions from a rock pile I go to and a few pieces of what appears to be bone popped out! Unfortunately when it did crack some of the pieces went flying and were unrecoverable While I do not know if it can be identified, I can hope it can somewhat be recognized. In the area I have found fossilized Cartilage through my Concretion cracking adventures and have found teeth from specimen of Eugeneodontida in the area. I also have come across the usual Brachiopods, Crinoid stems, Bryozoans, Rugose corals and petrified wood in the area. I believe this is some sort of fish bone, as to what it was? I have no clue. Below is the left side of the concretion

Help needed for preparing fish fossils from Caithness.
James_R_V posted a topic in Fossil Preparation
Hi everyone, Have been fossil hunting at Achanarras quarry and I have found what I am sure is an complete Dipterus valenciennesi. The only problem is that it is covered in a thin layer of hard stone. I am just wondering if anyone has had any experience with preparing Caithness fish fossils and know what tools are best for the job?

Last weekend we were invited by a few friends to joint hem on a fieldtrip in Famennian ( Late Devonian ) deposits in Belgium. They sometimes visit this place specifically to look for Devonian plant material. Although paleobatany is not our cup of tea they convinced us to come along because they had also found fish remains from time to time, so we tagged along in the hope to find some Devonian fish. At first we didn’t find much apart from the plant material, but one of our friends led us to a boulder where he had seen some fish scales on a previous visit. And indeed, after closer inspection we saw a big scale on the surface, but also a fish tooth from a Dipneustes. So once we knew what to look for we checked out different layers with the same correlation as the one where we had the first fish remains. It didn’t take us long after that to find a deposit where we found other fish remains, although the layer was hard to get to we did find some loose rocks from there that we cracked open with good results. Finally we got home with multiple scales from Holoptychi and Tristichopterids, a few Dipneustes teeth and we even found a quite impressive Arthrodire placoderm jaw. Most of this material was really brittle and we had to consolidate most of the specimens before extracting them. I would say not a bad catch for a first try at famennian fish Field pictures: This is an overview of some of the best finds from that day: dipnoi teeth: Tristichopterid: Holoptychius: The placoderm jaw:

Worn Protosphyraena Tooth? Found in North Sulphur River, TX
bluefish1766 posted a topic in Fossil ID
Hi all My kids and I found this tooth in one of the feeder creeks of the NSR in May. Someone said that it could be a worn Protosphyraena tooth. The leading edge is sharp; whereas, the trailing edge is round. It's also mostly compressed and broad-based. Any information or thoughts is much appreciated! Thanks!

Don't think I've ever seen a claw (other than crab) attributed to Lee Creek matrix, but could this be one? In person, it doesn't look like fish tooth or crab, so wondering what others think it might be. Not sure how well it shows in the photos, but It has a very prominent ridge running along its inner curve -- shown in last several pics. Scale is 1mm

I'm brand new to Fossil Forum, and can't afford the big splashy wall display fossils, so my "collection" is modest, but it's a start. I have three of these fern plates from St. Clair, PA, and two diplomystus fish fossils from the Green River formation in Wyoming.

Ratfish tooth from the mid-jurassic in Denmark
Sauroniops posted a topic in Partners in Paleontology - Member Contributions to Science
Hello there fossil forum! A few of you may have read my post about my 2 trips to Bornholm, a Danish island that holds a lot of different fossiliferous geological layers. I had specifically been digging by a location called "Hasle beach", where mid-jurassic sandstone layers are present. There have been found a few plesiosaur bones/teeth there, as well as 2 possible dinosaur bones, still being described, and also a few footprints. Other than that, mostly what you will find here, is shells, and occasionally hybodont shark teeth. As I mentioned in my last post about Bornholm (you can read it here), I found a ratfish/chimaera tooth together with the drummer from my heavy metal band. Our guitarist and bassist were nearby, as me and the drummer sat in one spot, opening several large eroded sandstones together, when suddenly a small black lump was visible within the orange sandstone. It turned out to be a chimaera tooth. When we were done digging for the 7 days we were there, we handed some of the stuff over to the museum on the island to check it out. I took the chimaera tooth with me home. About 1 and a half month later, a renowned Danish paleontologist made a lecture/presentation about dinosaur finds on Greenland. In between one of the breaks in his presentation, I got to talk to him, and I had taken some of my finds from Bornholm with me, including some plesiosaur bones, and the chimaera tooth. He took some of the stuff with him, to examine closer. He sent some of the bones back last month, saying it was some partial vertebrae fragments, which wouldn't be of interest to the geological institute. However, the chimaera tooth was interesting, as it was unlike other chimaera teeth found at the location. Today I just got an email from the paleontologist, that the tooth is in fact from a new species, and will be included in a scientific article about chimaera-fauna in the Hasle-formation! It has officially been declared "Danekræ", which is a title all "scientifically important" fossil-finds are given. It becomes state-property, and the finder/finders of the fossil are rewarded with some cash, as well as the honors of having their name attached to the find!- 19 replies

My son and I just got home last night from a 2 week fossil hunting trip. We loaded up the trailer and made our way up north to the Hell Creek formation in South Dakota. This was the 11th year since we started digging with Walter Stein of PaleoAdventures. We spent 4 days in the field at his Tooth Draw quarry. This started out pretty slow for us, with an Edmontosaurus neural arch with processes but was missing the centrum. My son found an unknown plate. Highly fractured but it looks to have 3 original sides. The underside is still encased in matrix so we wont know more until its prepped out while might take a while. The finds got better in last 2 days. We found a few big BOBs, lots of Trike spitter teeth, and then a nice limb bone, possibly from a crocodile. The last day gave up a wonderful complete Thescelosaurus vert with all processes. It may not be clear in the pic, but its all there in the matrix. Then came a Nanotyrannus tooth, a partial mammal jaw, a possible piece of turtle plastrom and a final tooth with could be nano or could be raptor. It will have to be cleaned to examine it better for a good ID. Sorry, I dont have a field pic of that one. The weather didnt get better though. Our last day it in the mid 90s, zero clouds and 40mph winds funneling down the draw and sandblasting us all day long. But with great finds, you couldnt pry us out of there.

More Scottish fish fossils from Tillywhandland quarry.
James_R_V posted a topic in Fossil Hunting Trips
I have been doing some more fossil hunting at Tillywhandland quarry and I have found a couple of nice fish fossils including a complete Mesacanthus mitchelli fossil. The fish has folded over it's self so it's head is pointing towards it's tail.

Yesterday I received a parcel from a member of the forum, containing fish and plant fossils from the Scottish coal measures, as well as a tooth which I found in West Yorkshire (UK) and sent to be prepared. My favourite of the Scottish fossils is a tooth which I am fairly confident is Strepsodus sp. Since little is known about Rhizodont teeth, it’s often very difficult to put a genus name to a particular species. Despite this, when I first saw this tooth the shape immediately made me suspect it is Strepsodus, so I decided to have a closer look at the striations. I was pleased to see that the striations look a very good match to Strepsodus sp in my opinion. I am therefore about 90% sure it is Strepsodus, and it’s the only tooth in my collection that I would call Strepsodus with any confidence. Sorry for the low quality photo, it’s quite small (5mm) and the shiny surface made it difficult to show the detail. Here is the tooth from West Yorkshire, before and after prep. It measures 12mm long, and is the largest tooth I have found in the Yorkshire coal field. It also the best preserved coal measures tooth I have found. This tooth comes from a mussel band, in which fish remains are quite rare, apart from in very thin fish layers which sometimes occur in the band. However, this is not within one of the fish layers. I’m not sure what fish this tooth is from, I suspect an identification would be almost impossible until more information about these fish is discovered and published. It is from the Pennine Lower Coal Measures formation (upper Carboniferous).

I found this really cool looking fish which is most likely a Knightia, but it's preserved in ventral aspect. The rear portion of the fish is missing including the dorsal fin so many of the diagnostic characteristics have been lost, but I still believe this is a Knightia based on the overall shape of the skull and the shape of the body. My question is more of a matter of ID'ing bones, because the main reason why I like this fish is you can see many of the bones that the typical Knightia does not show. I can see two operculum, one on each side. The lower and upper jaw I THINK are visible which is kind of weird because this is a ventral fish. The "gill" pieces which are my favorite part of the piece I think are called branchiostegals correct me if I'm wrong. But with many of the bones I have no clue. If anybody has input about this feel free to post what you have to say, I'm all ears!

I just returned from 4 days of digging in the Green River Formation. The quarry we dug in has 18”, mini fish, and upper gastropod layers currently exposed. Coming from Texas, we anticipated cooler temps but it was downright cold. High temps in the 40s and 50s with lows as cold as 30F! We had 1 day that was an almost total rain out but we dug 3 days and 2 nights on the 18” layer. We dug every day in the mini fish layer and randomly picked up pieces from the Upper Gastropod layer. On the second to last night, we went to bed in pouring rain and awoke at 3:00 AM to the tent collapsed on us due to heavy, wet snow! Everyone started pushing the snow off and the tent popped back up. Needless to say, we didn’t sleep much that night because we were now soaking wet and had to keep knocking snow off the tent. That was rather exciting g for Texans in July! Here’s our own little corner of the world. This pad of 18” layer produced some really nice fish, leaves, and a feather. Digging at night was a great experience, even though it was COLD!!!!! All in, we had a great time and I have piles of fish to prep now! More to come as I get specimens sorted and prepped. This was the view from the quarry after we finished digging on the last night of our trip around 1:30 AM.

Hi there! While looking for shark teeth, in southern Iberia, we found this strange fish teeth(?). Any ideas?
-
I found this - almost missed this - while sifting through some micro matrix today. I'm guessing some sort of fish tooth, but can anyone confirm? From Aurora Fossil Museum, Aurora, North Carolina. Lower to middle Miocene from the Pungo River Fm. It's so small that I have a hard time getting the camera to focus and my microscope cam just made it a big, black blob, so I apologize for the soft focus. That course rug it's sitting on is a piece of fine velvet!

I found this a couple of summers ago at the American Quarry in Kemmerer. Just cleaned it up. It doesn’t look exactly like a Knightia. Might it be something else?
