I'm stumped. I've been collecting erratics off the beach along the Delaware Bay for the last six months and I keep coming up with mysteries. This specimen is 1" long. Unfortunately, because it is an erratic, all I can tell you is that rocks of this type wash down from the Appalachians all along the Delaware River and Bay til it reaches the Atlantic Ocean. They are Paleozoic, but I don't know enough of the geology from PA and NJ to narrow it down by rock type to a formation. Can't find a high enough resolution GEO Survey map, either. Other fossils in this type of rock are rugose corals, tabulate corals, bryozoa, and pinhead-sized crinoids, so big possible spread on the time frame. No trilobites yet, unfortunately! I have a small id sheet from the Mahantango Formation and an ID book for the Middle and Upper Devonian of NY, but neither have anything similar. I posted on the FB group and got three people saying it was one of these (yeah, I knew that) but each thought it was a different phylum. Can I get a consensus on phylum, if not a genus here? Can anyone give me links to good reference material for my other mysteries?

There is a spot relatively close to me that is a late Miocene/ early Pliocene deposit. Consisting mainly of Great White teeth, marine mammal chunks, with occational (but rare) Meg. tooth pieces. Being a secondary deposit, everything in it got beat up and water worn pretty good. I was going through a box of bone pieces and grabbed this out for I'D. I was thinking inner ear bone? What are your views on this?

Finally made it out to Purse State Park, now known as Nanjemoy Wildlife Management Area, yesterday. I had read that there was no beach to speak of at high tide, but wow! Low tide yesterday was at 11:15. We got there at 12:30 and there was already almost no beach! If only we'd gone when @RCW3D went two weeks ago! The air temp was a balmy 50 degrees, but the water temp, not so warm. Did that stop us? No. Did we get frostbite? Maybe. We weren't expecting to have to go wading when we left the house 3 hours earlier, so warm, waterproof shoes were not with us. We went barefoot on the chilly sand, wading occasionally, then warming our feet again. That way, we had warm, dry shoes and socks for the trip home. The only fossiliferous exposure we found, admittedly not going far north as we'd have had to wade waist-deep, was between the two trail openings. There is an exposure of the Aquia Formation that reaches about 10 feet above beach level there. The cliffs further north are much higher, but empty, so not a lot to look at along the walls. That's okay, most people don't go to Purse to look at the walls anyway. There were plenty of teeth to be found on the beach until our toes got numb. I dug a hole in the sand in front of the fossiliferous exposure and to my joy found some blocks of matrix buried there after they'd fallen from the cliffs. There was also a complete oyster hanging in mid-air from a fine tree root, three feet above the ground, that I managed to slide off without so much as nicking the root bark. Ha! As an added bonus, I got to enjoy the forsythias blooming on the beach! There are almost no fossil shells on the beach. They are so punky in the cliffs that they just disintegrate when they are exposed. However, I am optimistic that when my blocks dry out I'll have some nice specimens that I can eek out with some dental picks, paleobond, and patience. I also brought home a backpack full of micro matrix to sift. Never know what might be lurking in there!

I live in Kitty Hawk, NC, and have the glorious Atlantic Ocean down the street. On a recent beach walk, I found what appears to be a fossilized bone from a large marine creature. I have looked through photos online and have not been able to identify it... and I am hoping someone might have a moment to satisfy my curiosity. It is approximately 9” wide and 6” tall... see photos below. I would be happy to take other shots if needed. Thanks very much!

This is my final post for tonight, and then I will stop cluttering up the forum. Unfortunately, this specimen has been badly weathered and so may not be identifiable at all, but the shapes are so intriguing that I can't help but ask. Any thoughts here would be very much appreciated. The two angles are from different sides of the same rock. Sadly, I did not find this specimen myself, and so I do not have any particularly useful information on age or location. It was left in a desk drawer along with a collection of other invertebrate fossils, most (if not all) of which are Paleozoic in age. Here are the pictures. Thank you in advance for your time and input. Side #1: Side #2:

Found this (likely Callovian) beauty today in Cracow, but probably it comes from Zalas, Poland. Any ideas on the ID? I'm towards algae for the moment.

Invertebrate(?) conical spines in Mississippian (Meramecian) Salem Limestone
pefty posted a topic in Fossil ID
Could use some help on these 0.5cm - 1cm invertebrate(?) conical spines in the well known Salem Limestone, a marine limestone of the American Midcontinent. They appear to be solid calcite but do not quite match up with the shapes of crinoid spines and echinoid spines that I know from the Mississippian. I have looked at umpteen Salem Limestone samples but have seen these spines at only one small locality. Any insights appreciated! but please provide your reasoning or evidence. -
Hello from a newbie in Central New York. I would appreciate it if anyone could identify the fossil in the attached photograph. I believe it is a tooth, but have not been able to find it on the internet. It has very complex, repeating stages in its structure. Thanks for any guidance on this! Norm

I would really appreciate your help in identifying these fossils from eastern Virginia. I'm not familiar with the formations enough to give a name. I think number 6 may be a Pleistocene horse? I'm having trouble with photo sizing. I will try to add another pic of the other side in the comments. Cheers!

Ok so some weeks ago I visited a friend in Bristol one of the days he was in work I ventured up north via public transport (which is always good fun especially when the buses run only every hour and stop at 6) so was limited on time a found a few rocks containing some surface but fragile fish scales, having never been there before I really should have thought on to bring some field tools but was a more spare of the moment type of thing, anyway so back home with the blocks and have just started processing them (and by them I mean 1 so far very nervously) by using a bolster and chisel and splitting along the sediment layers, first I was wondering if anyone has any tips on extracting fossils from this type of matrix yes it is limestone however I remember reading somewhere that using an acid such as vinegar can also damage the specimens. However what I have been ding is using a manual tool to very little effect and the dremel, the problem with this is the manual tool just isn't really helping with matrix removal and the dremel isn't chipping the matrix as effectively as I would hope and instead more crushes than chips (yes this is a dremel engraving tool however this vibrates rather than using a pneumatic action) the other thing I have been doing is using a syringe and very weak solution of b-72 protecting any specimens and using small amounts of vinegar on the surrounding matrix however again the amount that seems to be removed by the vinegar is minimal its probably soaking in to the matrix to be honest but I don't want to fully emerge the blocks and damage precious fossils, I understand this has almost become and essay of writing and was wondering if I should post in the preparations forum however I do have a few pieces I was looking for some id help with again first real exposure to fossils that are non dinosaur in origin, and first time ever dealing with this type of matrix. Any help is always appreciated Matt

Looking through the sieved material I noticed this little jaw ? I has come out of the marine material I get from Richmond in central Queensland in Australia. I refer to the layer it came out of as the fish mash layer as it is full of small fish material. In the layer I find fish, shark, turtle, Ichthyosaur, pliosaur, pterosaur and bird material. The fossil is 6 mm in length and quite fragile. Thanks in advance for any input Mike D'Arcy

Seemed like a good time to get this up. It was found in Little Brassua lake in north western Maine (low water, shallow lake). It is from glacial material that is most likely lower Devonian marine sediments.

As my whale family is nearly complete now I went looking for other marine tetrapods. (and big fish by the way). I had for some time included Thalassocnus, the unbelievable swimming sloth of Miocene Peru in my to do list. Really fourlegged tetrapods are quite a lot of work compared with the highly reduced whales, so I was glad when I realized that the Megaterium made by geoworld was more or less my scale when seen as a big Thalassocnus of 3.3 meters. It finally arrived the day before yesterday, and today I spent some hours making it look more seagoing. I lengthened the snout, smoothed the skull and jaw. sawed out the intercostal spaces and made the limbones less bulky. The spinal processes are pointing more backwards now. (or at least their edges are) I am positively surprised how well this cheap model turned out after only few hours of work. Aloha J

Hello, I collected this gastropod from a quarry along the Illinois/Wisconsin (USA) State line. Can anyone assit me with the identification? From the attached ID chart, I think that it is Loxonema. Thanks! Greg

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!

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.

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!

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 consider this important insofar as the various reasons for ,and processes involved in,marine invertebrate settlement are still being elucidated. uedanitrogenporiferasrep37546.pdf A must read for those with an interest in marine (paleo)-ecology Recommended for the deliciously informative fig.7 alone. 2,8 Mb,and it's from THAT journal

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.

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!

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
