Hi everyone, I'm not very involved with fossil collecting (more into sport cards as the name implies), but I bought this jaw fossil a while back and would like to request some identification help. Thanks guys!

Hi everyone, I bought this fossil a while back and its been a great conversation piece at my apartment. Thought you'd all like to see as well.

I’m doing a paper for school on Salinity, particularly how it effects the bay and the living things inside it. I’m also supposed to compare it to the world at large. As a bonus for myself, I’m looking to show how salinity fluctuations have effected past ecosystems. Do they find all the mosasaurs in the Kem Kem beds? Or is that just the dinosaurs? What is the age of this marine habitat? Also, any other studies on the past salinity in the oceans and the effect of the salt on the ecosystem would be helpful. Thanks all!

I went fossil hunting today in the Duck creek formation in Grayson county Texas. I saw these while hiking down a creek and was wondering if anyone could tell me what they are. I have seen these one other place, but didn’t know what it was then either. I suppose they could be a particular rock, but I tend to think it could be from a clam or something.

I'm a new member, so thanks for accepting me. My family and I have hunted for fossils, arrow heads, and sharks teeth for many years. It has been a way to pass the time on hunting leases and on the beach. It has always been a hobby, we have never worried about identification of any particular piece...until recently. Being retired, I started going through our collection, just for the heck of it. I found this piece that we have always been curious about. It was found in a creek bed on a ranch near Sonora, Texas, in northern Schleicher County. It was found 6-7 years ago, we leased the property for deer hunting for four years. With all that said, I posted pictures of it on a FB group. It has been called a "cone in cone" structure, an unknown type fossil, and a man made fake. The post on FB has been entertaining to say the least. One person responding recommended this group so here I am. I am in the Houston area so I would be willing to take it somewhere for a better look. Thanks in advance for any help you can offer.

Callovian. Southern Poland. Strata rich in ammonites, bivalves and brachiopods. Is it some kind of a brach or sth else?

I came across this little oddity while searching through some matrix for some micro specimens. As per the tags it is from the cretaceous and the environment is marine. I assume from the texture it is fish but what? It appears to be complete except for the rest of the animal it was attached to. Views are top bottom and side of the same piece. At 3 mm long it is quite small. At first sight I thought tooth but if that the root is very flat and square. Mike

I found these near Woodville MS, which is near the tunica hills region. Two of the fossils appear to be pretty common around here and I suspect they are marine fossils (a crinoid, perhaps?). If anyone recognizes them I'd love to know precisely what they are. The remaining fossil is more perplexing. I've found lots of coral in the area but nothing that looks quite like this. It reminds me of the pulp of a fern tree or something but I'm wondering if it's not just a different species of coral. Thanks for your help!

While sieving through some matrix I came across this unusual tooth The tooth is from the cretaceous, albian, marine matrix from the toolebuc formation in central Queensland Australia. at 10 mm long it is not very big but there are striations on both flat sides, making it unusual compared to the normal fish teeth that are abundant. The edge on one side appears to be slightly rounded and the other that is chipped is quite acute. Thankful for any leads Mike D'Arcy

Hello all! Happy Georgious December! (almost 80 today!) Anyway, I got a rare day away the day after Thanksgiving and took my oldest back to the Ladonia Fossil Park on the North Sulphur River. We normally hunt upstream of the 2990 bridge, but thought we'd slow the pace down and get into the gravel. We knew we hadn't had any recent rains to clear out all the shale clasts that have filled the river bottom for the last several months. While much of the "Mush" has either dried and crumbled, or washed away, there is still a lot of it covering the ground. We found very few actual gravel deposits around the park except where exposed by hundreds of boot prints. We did find a few various shark teeth, a broken mosasaur tooth fragment, some Mastodon tooth enamel, - the normal finds around there. We noticed a family leaving and they had been digging around the bank where the gray clay/silt turns to a tan color - well above the Red Phosphate layer. One piece they had dislodged looked interesting and as we moved it, it broke open to reveal the fossil below. I've found fragments of this before upstream of the 2990 bridge, but never this much of it. I got a couple of pics right away, since this material starts to dry, shrink, and crack pretty quickly. We then wrapped each in plastic and soft cotton to transport back. However, the side of the fossil with the shell turned to dust and disintegrated. The shell is paper thin (like some of the larger white baculite shells) and is only the surface shown (meaning it doesn't curve around in the matrix and finish on another side. It's just this surface. One side has raised bumps and the other pentagonal depressions in the cast. First glance is the shape of a paddle (like turtle), but a) it's a shell coating - and b.) it has no bones. It's purely shell. It doesn't extend further into the matrix block. I'm good on most things Sulphur River, but this has been a mystery every time I've found it. Thoughts? Texas, North Sulphur River Ladonia Fossil Park Ozan Formation

Puzzle in poop - Cartilage, denticles or tooth plate in coprolite?
GeschWhat posted a topic in Fossil ID
I have been finding a lot of inclusions in a batch of coprolites from the Smoky Hill Chalk that assumed were bits of cartilage. One of the newer specimens from that batch had a piece of the material in question on the surface; enabling me to view it from the side. They look like little teeth, so now I don't know what I have. I have one other specimen that has a couple of the little tooth-like structures intact (one that I posted a while back that has possible Ptychodus tooth fragments). Is this skin with denticles, cartilage, a skull part or some sort of tooth plate? As always, any help is greatly appreciated.

I have done a little bit of sieving and found this interesting little vertebra. Its quite small at about 3 mm long and was found in the cretaceous (Albian) of central Queensland Australia. The specimen was found in a cretaceous sediment from a marine environment, however I do not think its a marine animal. I have a good idea of what I believe it is from but comments would be appreciated. Mike D'Arcy

I have been quiet for a while but, sifting through some matrix from the cretaceous of central Queensland Australia I have come across some small fragments that I suspect to be bits of either a spine (spike) or bone. The bit that has me thrown is there is a distinct grain (striations) appearance on the outer surface that has thrown me. This was found in the same batch as the tarsal so could be a clue or a red herring. Photos of top and underside as well as an end view. Any suggestions appreciated. Tarsel 4.5 mm - longest unknown bit in two sections 18 mm so not large Mike D'Arcy

Hello, Everyone. This is another sample from Runswick Bay on Yorkshires Jurassic Coast. I'm hoping that someone will tell me that is a paddle bone from a marine reptile. All replies gratefully recieved.

Need help identifying this fossil I found while trying to find shark teeth on Tybee Island in Georgia. One photo is in b&w so I could fit both sides on this post.

The specimen comes from south-east Poland from Late Cretaceous marls with cherts, rich in sponges and echinoids. It is in a form of a cilinder covered with striae, going through the whole rock piece, which is part marl, and part chert. Is it a fossil?

Happy belated National Fossil Day! Hope I'm not overstepping from bounds by posting this, but a few people on the forum have asked me how to get out to the one accessible spot left at the C and D Canal in Delaware. It's tricky to find and doesn't look like much when you first get there. I am leading a trip out there this Sunday for Delaware Nature Society as my somewhat belated, but more publicly accessible, National Fossil Day excursion. We are going to be out on the plain that is a the spoils from the canal for a couple hours looking for treasures, but it won't take more then a few minutes to find your first fossil out there. You are welcome to stay and play until sunset if you like. The web site says "Families with children ages 7 and up," but this does not mean that adults with no children in tow are unwelcome, only that the terrain isn't really good for shorter children. The cost for non-members is a whopping $18 per person. You can keep anything and everything you find. People come home with buckets of Belemnites, oodles of Ostrea (well, Agerostrea), and generous numbers of gastropods. Occasional Echodus and shark teeth are also around, but pretty rare in this spot. You can see some of what I've found out there in my album. The matrix is loose sand. Just walk around and pick stuff up! We'll clear a spot of weeds and do a little sifting, too. Register online today. https://www.delawarenaturesociety.org/DNS/Events/Registration/Event_Display.aspx?EventKey=F17066AS#.Wd9iJUzMz6c While you're at the DNS visitor center to meet for the trip, you can stop inside and see the displays I'll have set up about Fossils from Delaware and beyond. How well can you tell a fossil from a modern shell or a pseudo fossil? Ever looked at a fossil shell under black light before? See the variety of fossils and ages to be found in our tiny state. Or, if you're not going on the trip but just want to explore with smaller folks, sift through the kiddie pool, for canal fossils I collected earlier this year and for Florida shark teeth donated by the Delaware Museum of Natural History. While I'm around I'll be preparing some matrix from Maryland with my handy dental picks. The visitor center activities are free, but trail fees for the rest of the property apply. The visitor center activities will be open Saturday and Sunday, 9-4. For directions, visit www.delnature.org.

Hi! I found this near a marsh in the back bay of southern NJ. It is approx 1" x 3/4". Can anyone help ID it?

I recently hunted in the Austin Chalk (in Austin) for the first time and am unfamiliar with the fossils there. I posted another ID question for something I found and the ammonite suggestion sent me on a research mission. Now I'm wondering if something else we found was actually ammonite aptychus instead of the bivalves I thought they were. Most of the ones I saw online were MUCH smaller, but looked very similar. What do you think? I didn't bring this home so can't get any other pictures/measurements. I really need to pack a ruler in our gear! I have pretty average sized hands.

Founds this in Austin, in the Austin Chalk. It's 10 cm across. Any ideas what it is?

Hello everyone! I found many fossils in my last trip to a mountain in Valencia, Spain (as far as I know the strata in that mountain are Jurassic/Cretaceous) but I can't identify these 4 fossils displayed in the pictures below. I would appreciate any help, thanks!.
-
I think this is basically a Mucrospirifer mold but what else is there ? Primarily the rugose feature. Pedicle attachment ?
-
I found this teeth in a marine sedimentary sandstone (Cretaceous.Palaeocene) and I don't know what is it.

Hi all, I recently found this on a trip to the Jurassic Coast at Dorset and have been intrigued by this find, i'm not an expert on fossil identification and was wondering if there was anything significant about this fossil. it strikes me as being either fossilised wood or an infilled burrow of some kind, however the shine, shape and downward strikes are leaving me somewhat puzzled. i would be grateful for all your potential ideas as to what this could be.
