I live in Fountain, Colorado (south end of Colorado Springs), at the base of the Rockies. I found a perfectly preserved sea shell a couple years ago had me think it might be ancient; a fossil from when the region was part of the Western Interior Seaway. And that shell (not shown in these photos) has me "browse" the ground on occasion. Recent earth movers' excavation of the same grayish colored earth I found the shell had me looking for fossils the other day. And in relatively short order, I found this. My first thought was...fish fin, but the small (1-3 mm), whitish fragments of what might be shell fragments seem odd, combined with the fact that whatever it is, is more than just a surface imprint. See 2nd photo showing how it's got some thickness associated with it, unique to the rest of the rock. The 3rd photo shows the lines curling down along that side of the rock. Though I've watched a fair amount of shows on archaeology presented on channels like NatGeo, Discovery, etc., showing the process of removing rock from fossils as very tedious, I'm as amateur and unexperienced as it gets with such processes. So I'm reluctant to try to remove any of the attached rock, which looks like might reveal more of the curved (and underside) of whatever it is. It's heavy for its size and the rock is too hard and dense to easily break or scrape away.

I found this the other day in a Middle Cenomanian shell hash layer. It is about 30 mm long. It seems to be absent sharp teeth and instead has some type of crushing dentition. But, I'm not sure that it's even a jaw. It could be a fragmented fish fin or split spine. Does anyone have a good idea?

Found these on a shoreline in coastal South Carolina. I assume the larger vert is shark and smaller ones are fish. I'm mostly curious if there's enough of the big bone piece to get an idea what it is. The hole goes all the way through but is clogged with debris.

Anomalous Sample from the Wealden Beds at Hastings, Rock-a-nore, UK.
blackdanter posted a topic in Fossil ID
Hi folks, This is an anomalous specimen from my collection. The location is early Cretaceous, around 140 million years old. I've never found anything else quite like this at the location before or since (I collected it a few years ago). It has the appearance of being blob or pancake of material. It's composed of hard clay pea sized matrix with a soft clay infill. One side has an ironised layer which looks as though it covered the whole thing at one time. Under a lens, the soft clay matrix is packed with really tiny fish teeth, spines, scales and bone fragments. The intriguing thing is the larger fragments, which are scales and bone. You do find assemblages of fish scale/bone, shark teeth/spines and reptile bones at the location but these are usually on the surface of beds of sediment (not in a 'pancake' like this. This material is not even remotely similar to 'bone bed' material which occurs 4 miles East along the coast at Cliff End (the tides here push material Eastwards), There are obvious bits of small broken bone (shards). These have the appearance of the shards left over when your dog has destroyed a bone. In addition to that there are other bits which appear 'polished'. I can't decide whether these are broken teeth or somehow polished bone. To be honest the whole specimen feels like fossilised animal 'up chuck' of some sort. The edge on the left of this image shows the ironisation layer, this edge is also covered in quartz type crystal material. Quartz infill/crystals are quite common at the location in ironised nodules. A fish scale and two bone fragments or teeth. One is conical and points upward and one looks like a piece of rib except one end has cellular structure whilst the other end is solid. At the top of the image is a small damaged croc tooth. A closer image of the anomalous bits. They don't look like any teeth I've come across before. All of the black 'peppering' is tiny fish teeth, broken spines and a few tiny scale fragments. The second anomalous bit. Polished bone or tooth? I originally suspected croc tooth but the shape is really odd, elongated peg like would be the best description but the polished surface is weird looking to me (like a piece of polished dinosaur bone you might see at a gem stone sellers). Another piece of bone poking out. I have recently started exposing this. There are a couple of other 'suspect' areas i also need to investigate at some point. Any thoughts/observations appreciated.

Interesting shapes when I split this rock Hudson River, Albany, NY
Honeymayoon posted a topic in Fossil ID
Found this along the Hudson River near Albany, NY. I split the rock to see what was inside and it. An ID on any of the fossils would be appreciated!

Forgot the name of these fish. Can someone please ID them again ?
Brevicollis posted a topic in Fossil ID
Hello, I got these two fish as a birthday present last year for my thirteenth birthday by my parents, and also the name of them. But it sounds wild, but now I've completly forgot the name ! I only know that they were found in the copper shale near Mansfeld, Germany. Can someone please identify them for me again, and I'll promise to label everything. Sices are 16 and 21 cm, the plate weights around 4-5 kg If you need more and more detailed pictures, let me know! Thanks !

drum fish mouth plate found on the kaw river -
Hello, I'm sorting though microfossil matrix from the Permian Texas red beds. I'm not very familiar with this area, but understand that there are shark, reptile and amphibian teeth in it. Could you point me to a guide or other literature relevant to this location or help me to understand most of what I'm looking at? I've found specimens as large as 5 mm and the smallest can't be picked up with my tweezers. This matrix has been sorted under a cheap microscope, so I'm sorry the pictures are rather blurry. Thanks for the help. (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11)

From the album: Chondrichthyan Teeth From The Pennsylvanian Period
This tooth most likely belongs to the Raytown Limestone member of the Iola Limestone formation. I found this during late March/Early April. I call this my first Peripristis tooth as I happened to find one 2 hours away from this locality a few days ago. I will upload that one later.- 4 comments

Hi forum, i recently went to Solnhofen quarries (DE). I found some cool pieces and an amazing little shrimp! This one piece instead is something a little new to me. It looks half bones half cartilage...i can't tell. It should be something fish-related but i can't tell, it can be something totally different. I'd like to know which part of the body it is to better understand how to continue preparation wihout damaging it. The big middle bone looks strange, very thin and transparent on the border and more thick and orange/brown in the center. same as the cartilaginous part in the left. no clue i report some flash/noflash picture also in different angles. the sand around is a little dark because it is wet. the total uncovered length is about 4cm Thanks a lot Best regards Paolo

From the album: Hell Creek Formation Microsite
I found a few holostean-grade scales that haven’t been attributed to more precise taxa, and are referred to as holostean “A” and “B” in the literature. These are not gar and are something else.-

My First Vertebrate from the Florissant Fossil Beds
Opabinia Blues posted a topic in General Fossil Discussion
Hi all, Last weekend I took a trip, again, to the Florissant Fossil Quarry. The quarry doesn’t normally open until Memorial Day, but I went with the Colorado State University entomology club. I successfully lobbied for the club to take a field trip there, and the club got the trip funded by the student’s association so we got to go in as a by-appointment special group for “free” (at least for us). Perhaps this whole process is a story I’ll tell another time. Anyway, for those not familiar in the upper Eocene Florissant Formation fossils of insects and plants are highly abundant, but fossils of vertebrates are exceptionally rare. This is despite being a superficially similar depositional environment to the Green River Formation, where fish fossils are abundant. Well, after countless total hours of splitting in the quarry over the years I’ve finally come across a vertebrate fossil - the head of a teleost fish! This is exciting simply because fish fossils are very rare in this rock unit. The shale breaking split the fossil, so presumably the body is still out in the quarry somewhere. There are of course fish described from Florissant, but I’m not familiar with them. The only identification I can readily make is teleost. Thought I’d share a rare find! My “white whale” for the Florissant Formation is still a spider fossil. There were three spiders found by entomology club participants, but of course I was not one of them. Of course I’d find the way more rare thing, but not the thing I wanted 😀
