Miocene of Virginia- Calvert formation

From the Miocene of Virginia- Calvert formation

Hi, I got an ammonite fossil from my friend but we can't tell which genus it is. Could anyone help to identify its genus? Thanks Ken

Hi everyone! I'm a newer member to the fossil hunting community. I first started as a little kid, but have only really gotten into it over the pandemic as a hobby. I've done some hunting up around Dallas where I'm originally from, visiting famous spots like NSR and POC. For college, I'm currently living in Austin and have checked out a few nearby spots. These past few months I've been frequenting a local creek that runs through the Ozan layer and have been finding some cool fossils/artifacts. The items I am showing you today are collected from two places. The first assortment (lots 1 and 2) are from the NSR and contain Cretaceous/Pleistocene fossils. The second group (lots 3 and 4) was collected in Austin and contains Cretaceous fossils as well as some artifacts. For some objects, I am fairly certain of their identity, but for others I have no clue. Some fossils/artifacts have additional closeup shots for greater detail. Any comments or tidbits of wisdom concerning their identities or fossils in general would be greatly appreciated! Lot 1: NSR fossils I am fairly certain of 1A: Vertebra I believe to come from a mosasaur. 1B: My favorite piece from the NSR: A mosasaur tooth with a sizeable chunk of seems to be bone/root(?). It's a bit weathered, but there's still enough to get the imagination running! 1D: A nice little red bivalve from the red layer. 1E: A fragment of Pleistocene tooth I would love to know more about! From looking at the folds on it and doing some researching, I feel that it could be from a horse. 1G: The nicest piece of baculite I found that day. 1H: I'm not sure if this is a piece of coprolite or just a random cluster of two fossils. There is an identifiable baculite fragment and gastropod. Moving on to the second lot from the NSR, these are the things that I have very little notion concerning the identity of: 2A: Could just be an oddly shaped piece of sandstone (as it has that texture), but it does make me think of a scute. I would love to hear what y'all think! 2B: I truly have no idea what I am looking at. It feels like a fossilized "something", but that is all could really say. Here are some closer pics: 2C: Petrified wood? 2D: Very strange texture. My initial thoughts were some type of bone or petrified wood. 2E: Rock with fossilized bits of something that is difficult to identify. Maybe fish parts? 2F: A piece of cylindrical bone I believe. 2G: Piece of turtle? 2H: No clue. 2I: Petrified wood? Lot 3: Fossils from Austin Creek that cuts through Ozan layer 3A: Fairly certain this is an ammonite valve. Found quite a few in this creek for some reason. They never want to be whole. 3B: Good size vertebra likely from a mosasaur 3C: Really don't know what this is. My best guess is some really weathered down ammonite. It has symmetry and an overall spiral shape. It kind of reminds me of a curled up shrimp. Would love to know more about it! Here are some closeups: 3D: Nice little heart urchin. 3E: Nice urchin. I had only ever found heart urchins until this one, so it was an exciting find. 3F: Gastropod. 3G: Have yet to find a complete shark tooth from this spot, but here is a fragment. Might not be enough to secure an ID, but it's worth a try. 3H: Strange little fossil. Seems like some bryozoans grew on it at one point. When I look at it I get thoughts of echinoids and crinoids. Would be interested in hearing y'alls thoughts. Lot 4: Artifacts from the Austin creek (I know this isn't an arrowhead forum, but I figure there's a lot of overlap in hobbyists so there could be some insights): 4A: I believe this is a part of a larger tool like 4B. Not sure if these are knives, scrapers, or something else. 4B: Knife, scraper, or something else? 4C: My favorite artifact. Super pretty and thin. My guess is an atlatl dart point? 4E: another point, though not as visually appealing as 4D. The base looks a lot different too. Could this be an atlatl point? 4H: The base of some point. Would love to know more about the names or dates of any of these! If anyone would like more closeups of a specific item, feel free to let me know!

Thank you for your time and the ad to the community,I'm definitely a rookie,I live in Arkansas..really in the middle of nowhere,which is great because I get to explore alot of untouched land,overhangs,caves,ect..I found this in a cave that was full of bones and alot of native American artifacts ..I've tried to do my own research on it but I definitely need help..I also have other very interesting finds I would like to post after this. Thank you for your guys help and time .truly appreciated... Scott C

I found this over the weekend at Wilson’s Clay Pit (Harpersville Fm, Pennsylvanian). I know that there are a number of strange looking rocks there that look like something but are really nothing. I ended up picking it up and keeping it because it was unique and I thought that it could maybe be something. Does anyone know what this could be? Is it just one of those rocks that look like something but is really nothing?

Hello to all of you guys, a couple of weeks before i asked for help in relation with some shark teeth, and the help indeed was very nice! A couple days before i was back in field trip and found some more teeth from the same strata, and would need your help for the correct ID (hopefully at species or genus level), you guys are awesome!!! Here´s the list of the fossils (each step of the ruler is 2mm): 1) A tiny tooth with very small roots and 3 denticles, the central and main one is triangular and very oblicuous 2) A tooth with very triangular cusplets and with small and shorts ridges in the base of the main denticle (wich is slightly curved), the roots are slightly asymmetrical 3) A half of tooth with triangular cusplets and with a slight triangular depression in the base of the main denticle (wich is slightly curved) 4) A (i think so) stingray tail fossill 5) A tooth that i dont know what could be (the tip is very smooth and the roots have a wood-like texture) 6) A tooth that i think is from Premontreia subulidens, but im not 100% sure 7) Something that i dont know what it is, looks like some kind of skin or membrane 8) A tooth similar in color and root texture that number 5, but with only 1 denticle 9) A tooth with very triangular cusplets and low developed roots 10) A tooth with maybe similar look about Carcharias teretidens? but with slightly longer lateral denticles 11) A tooth with aparently only one denticle, and asymmetrical roots (the rightest part of the right root is easly confused with the sandstone matrix) 12) A tooth with two denticles, striae in the lingual face, triangular depression in the base of the main denticle and the base of the crown is much more prominent that the diameter of the main denticle, might be reworked because is from a level stratigraphically higher. Finally, as a bonus track, here it is a vert. that i found in the same field trip:

In fact there was one more box to open,always without ID :(,it's very light and strange,natural?

So I got this bone chunk that came in a bag that just said Edmontosaurus Bone from Hell Creek Formation. It looks like it might be an identifiable bone. Just wondering if it's identifiable or just chunkosaur. Here are the pictures.

The very last unknown ID is this polished green slab. I'm looking for green stones on the web, but I still am not finding a slab like this one. If somebody could help?

I found these coral? Fossils in Ignaberga Quarry, Sweden Upper Cretaceous. I like these fossils and would really like to be able to id them.

In the old collection ,i also find this slab,and after few search i have found this ID:Utah sandstone (united states) kanab sandstone is it right?They sell pieces of the cliffs ? There is also this very strange very fin slab,Dali last paint?What is it?? Thanks for the help !

Hi, folks, I found this slab of rock on the shore of a guzzle in the Seabrook marshes (NH). I can't tell if these little black structures are fossils of some kind or mineral accretions. Thoughts? Thanks!

I have a couple dinosaur bones that I'm not quite sure what they are. The first one is a vertebra from the Hell Creek Formation of Harding County, WY. The seller had said that it was probably either Thescelosaurus or Pachycephalosaurus. I had been wondering if any further identification was possible. The second one is from the Judith River Formation of Hill County, Montana. The seller had listed it as Hadrosaur indet. Would that be able to be narrowed down to a genus? Also, does anyone know what part of the jaw it is from? Thanks!

i received few minerals(sometimes sliced and polished) from a old collection mixed with fossils,mostly without name and location ,i think these are fossil wood;i think it's probably from Madagascar,is it possible to find the location?

Hi everyone, Found this lil' biter on the French coast at Cap Blanc-Nez. A local told me it was a shark tooth but he did not know the species. Anybody know what species of shark this is (if it even is a shark)? Tooth is about 1.5-2 cm long. Thanks in advance!

i received few minerals(sometimes sliced and polished) from a old collection mixed with fossils,mostly without name and location some are very easy to ID (I think),but i know nothing about minerals,if somebody could help?It would be very happy,regards

i received few minerals(sometimes sliced and polished) from a old collection mixed with fossils,mostly without name and location some are very easy to ID (I think),but i know nothing about minerals,if somebody could help?It would be very happy,this one seems to be for me kind of coprolithe,perhaps??? regards

Found on a beach in Yorkshire. Not entirely sure what this is. Many thanks

I submit 3 bones today: Age: campanian Location: south of france Deposit: continental / river Bone 1 : 10cm wide, thickness 3 mm. I dont think it is a shell Bone 2: 6cm long, view from the top and from the side Bone 3. 21 cm long. 1cm thick on one side. 1mm on the other. Convex.

When it come to small teeth i always have a problem differentiate spinosaur tooth from croc tooth . I need a bit of help ID this 2 two . all from Kem Kem basin . both unserrated . thanks in advance Guns tooth 1 : Rooted tooth This photo is aim to show the striations and cutting edge on this tooth Here some close up photo... tooth 2

I found this a few weeks ago at an exposure of the Late Pennsylvanian Colony Creek Shale in west-central Texas. I have no idea what it could be. It seems like a partial something, but I just don't know what. Maybe some type of cephalopod? Any thoughts are greatly appreciated. I thought the pattern was interesting enough to pick it up and try to figure it out. Thank you!

. . . . . . . . . . . . Looks like some kind of Ammonite perhaps - found near to Filey (Hunmanby Gap/Reighton Sands). Question is, if it is a fossil, where do I WALLOP it with the hammer, please?

It was found in a Devonian exposure in western Virginia. There are orthocones, brachiopods and other aquatic life in the exposure (with some being pyritized), along with other plant fragments in the area.

Hello, out of curiosity, I just wanted to know the id of this animal's jaw while diggin in my backyard (inside a solo cup for size)
