  1. Shark Teeth ID

    Have found these at the beach. This is the best picture I can get at the moment. What species of shark are these teeth from? The bigger one is about an inch big. Thanks!
  2. Need help identifying

    Hello. My name is Joy and I know I will find this forum very useful. I am learning about how to spot fossils and may need help from time to time. I found this today here in Katy in a pile of rocks near a flower bed and would really like your input on what I am looking at. Thank you for your time and expertise.
  3. Seabed ID?

    Hi, I found this in near Sparta Kentucky. Anyone care to identify/ date? Found on a construction site so I couldn't tell you exactly where the layer was.
  4. North Central Texas Fossil?

    Just wondering if this is a fossil and of it is, what do you think it might be? Sorry I didn't have a ruler when taking pics. My thumb is on the pics and it's about an inch or a little less across. This was found in a limestone riverbed near Justin, Texas (North Central Texas). We have found many other smaller marine fossils (actually casts I think - I am not an expert by any means) that I am pretty sure are from the Cretaceous Period in the same area. I have more pictures that are higher resolution, but I can't upload them here due to the size restrictions. Thanks in advance for any info or ideas that you might have.
  5. I like to have extant teeth in my collection to contrast with fossil teeth of the same or similar species. I bought these teeth at a tourist shop in Las Vegas a few years ago. They had been made into necklaces. I thought they might be H. elongata based on the root shape and would be interesting to display along with my fossil H. serra teeth. I am not convinced my ID is correct, especially considering the serrations go all the way to the tip. Any ideas?
  6. Heyo! Found on the river banks of Humber river in Toronto, Canada I came across this rock this weekend and I was not sure if it was anything special or just a peculiar shaped rock. After some hesitation I decided to pick it up just in case. It has a very distinct wave looking shape to it and the texture on the 'wavy' surface seems rather fossil-esque but I wasn't sure as the cross section doesn't seem to show much of anything. If I had to take a guess I would say its either a coral or maybe its an imprint of some-kind? Let me know what you think If its anything worth keeping or just random rocks: /\ These two pictures show the general shape and size of the piece. /\ These two pictures show the close-up texture on the surface of both sides. /\ This is the side/cross section. Thanks for the help! -Em
  7. Help with shark tooth ID

    I'm new to shark tooth hunting and can't figure out what type of shark this is from. Can anyone help?
  8. Fossil Identification in Western Wisconsin

    *Higher resolution and many more images linked below to Google Drive for a clear view* Fossil: Large limestone rock containing hundreds of marine fossils and with what appears to be a bone roughly 3cm in diameter. As well what appears to be the remains of other bone structures. Location: Found 10 miles from the Mississippi River near Ellsworth, Wisconsin USA (Western Wisconsin) in a low valley area that looks like an ancient river bed. Rock Measurements: Roughly 15cm x 28cm My Understanding of Geology and Paleontology: 2/10 *There are a vast amount of images so I'd uploaded them to Google Drive in high resolution here: https://drive.google.com/folderview?id=1-QkitLR3bwWFEn0Dh6OoNngsH8F5O31w I found this large limestone rock on our property near what I imagine would be an ancient riverway located at the bottom of a recharge point (aka hill). During heavy rains this area can literally turn in to a river and wash the soil down stream. This rock appears to contain all of the common marine fossils you'd find in Western Wisconsin from what I've researched. However, there's what appears to be a bone or unusual looking aquatic creature near the snail as shown. The snail was extremely well preserved before the vinegar soaking ate the shell and pigment away. A bit more about the location in which it was found; I had been landscaping the slope of the soil for about 2 years in the backyard by shovel. I had lived in this home for about 4 years and I found the soil to be unusual versus any other home I've lived in nearby. The heavy, wet clay soil contained many large green basalt rocks - I'd never seen one before this time. The bedrock is limestone but about 100 FT away the bedrock is sandstone (according to geological maps). The Mississippi river is 10 miles from this location in western Wisconsin near Minnesota. It's also in the path of the "Great Midcontinent Rift" which I find interesting. There are also many large "bluffs" and rolling hills. It's a beautiful area. Anyhow, I'd like to find out what else may be in this rock. It has been in vinegar for about 2-years and is slowly changing shape which in my imagination resembles a skull. I'd like to find a means to protect the exposed fossils while the limestone is absorbing. I had read something about fossil glue or plaster that can protect the exposed fossils while in the acetic acid. This is an educational experiment for me and I've always wanted to learn about paleontology and geology. Any help and identification would be appreciated! There are so many fossils and things to look at in this rock that I uploaded the images to a public folder on Google Drive so that others can view them in a higher resolution. My Galaxy Note 8 is not the best at focusing on close up images so please forgive my photography. If you see something interesting I'd be curious to know! Thanks! -Jack from Western Wisconsin (Google Drive images: https://drive.google.com/folderview?id=1-QkitLR3bwWFEn0Dh6OoNngsH8F5O31w)
  9. Nano vs T. rex?

    I have two similar sized teeth that were both from Hell Creek. One is a large nano tooth (left) but the other may be T. rex? The one on the right certainly is fatter. Thoughts? Thanks
  10. Part of a segmented fossil?

    Greetings! I found this fossil on Sunday in Bradenton, Fl (Manatee County) It is 1.5”/38 mm long, 1.5” wide and .5” thick. It appears to be broken on 3 edges. I tried to photograph it on white background but some pics where I am holding it turned out sharper. Some of the things I found nearby were horse teeth, chunks of meg teeth, tiger shark and hemipristis teeth and the most massive Florida horse conch and mollusks I’ve ever seen. I’ve been trying to learn the age and specific formations that I hunt in but it’s been confusing to me. Is it possible that I’m in the peace river formation if I’m 40 miles west of the actual river? Or would it most likely be the Arcadia formation, or even bone valley? Some overlap so how do you tell? I think I am mostly in Miocene- Pliocene. Getting a bit off topic but if anyone can shed light on my mystery find and possibly clarify on formation locations I enjoy this forum so very much. Thank you all members. Best, Marie
  11. Unidentified Tooth

    This is a fossils I found on Edisto Beach in South Carolina. To this point I've assumed it's a tooth but I'm not 100% due to the apparent lack of a root. I originally thought it belonged to some kind of ungulate but under further research it could possibly even be some carnivorous incisor? Either way the curiosity is killing me! Tell me what you guys think. I left the photos large to retain detail. It is exactly 1 inch in length, or about 2.5 centimeters And 3/8 inches in height, or about 1 centimeter If you need any other angles just let me know, its super hard to photograph.
  12. Shark teeth identification help please

    Please help identify these teeth from Conecuh River, Andalusia. I pulled about 500 teeth out of the deposits and these tiny teeth are the only ones of its kind in the bunch. They are about 5mm X 7mm. Thanks.
  13. Modern Shark tooth identification

    Hello, I´m not sure about the ID. For me the tooth looks like a Hemipristis or a bull shark tooth. The tooth is from the Indo-Pacific (Phillippines) and 1/2" (1,5cm) in lenght. I want to be sure with the ID because I do not want to buy a tooth of a protected species. I don´t know, if the question is correctly ask in the Fossilforum, but I hope, that you can help me. Kind regards from Germany
  14. ID references for Eurypterids

    Hello all! I'm looking for recommendations on good resources to help me identify a ton of material that I recently acquired from the Sojka eurypterid collection. I believe it is all from the Bertie Waterlime, but I can't be entirely sure. Some of the pieces have collection numbers, but I don't have access to the collection records. I am guessing that any of the collection records went with the rest of the collection to the Yale Peabody, but I can't imagine that I would honestly be able to match up the information without a lot of time and access. There's a lot of assorted material and lots of bits and pieces to ID. I figure that this will give me a good opportunity to learn a ton about a new subject! Thanks! - J
  15. Possible triassic track?

    I found this near the 476 turnpike where they tore up all the ground and exposed the New Brunswick Formation. This formation is triassic. I went to a dump site where the construction company took all the rock. Is this possibly some sort of trace fossil from a lizard or sphenodontid? (If you neer to see it better flip your phone or device upside down)
  16. Especially inspired by this object: http://www.thefossilforum.com/index.php?/topic/96343-stone-found-on-beach-in-wales/ but also many others posted in the ID section, I would like to discuss the possibility of construction of a flow chart for "object identification". But I don´t know, if this would make any sense or if it could be helpful. Both for the more experienced ID people or for the unexperienced ID people. It don´t need to be detailed, some "end points" I am thinking of are (of course, it can be deepened endlessly!): Artifact (modern, native American, etc.) Fossil (mollusc, tooth, Dino bone, mammal bone etc.) Rock (limestone, granite, schist etc. Concretion (siderite, pyrite, calcite etc...) Mineral (Calcite, Quartz, others etc.) It would be a long and extensive work. But my interest is more general: Is it even possible and does it make sense? Franz Bernhard
  17. mississippian fossilerous limestone

    Can anyone help me identify the vast array of specimens on this slab? I see some rugosa.
  18. I have no clue what this is. But I do know that it's middle devonian.
  19. Okay so I found this interesting specimen in Ithica New York. The formation was early devonian. Is this a cooksonia fossil? On the other side of this rock you can see another fossilzed plant as seen on the front but much smaller and less complete. Below the penny is the most complete out of the three. To the right of the penny you can see a little bit of another. Thank you for taking time reading this. (If it does turn out to be a cooksonia its sadly missing the sprouts)
  20. Found shell like fossil

    I found this fossil it kind of looks like a curled up tail of a crayfish but I’m uncertain.
  21. North myrtle beach find

    Here is another item I found in north myrtle beach! I'm not sure what it could be....I already have sea robin skull plates, and it doesnt look like that, but maybe it is something similar? Any help is appreciated! Posted are the top, then the bottom of the object
  22. Here is another item I found in north myrtle beach! It looks like the tooth of a crocodile or toothed whale that's incomplete, but it also has the look of a claw....or could it be something else?
  23. Fossil or not?

    Found this rock on our place in southwest Colorado. It’s very different from most rocks here. With a little research I found we are located in the middle of the Morrison Formation! I’m interested to see if anyone could help identify it. Fossil or cool rock? Thanks for your input.
  24. Identification App

    I know this isn’t a website, but I didn’t know a better place to share this. I came across a decent little app for iOS that helps with fossil identification. It’s called Digital Atlas of Ancient Life. It’s database is limited, but growing. It has a lot of information for the fossils that are in the database. It’s managed by the University of Kansas and is supported by a grant from the National Science Foundation. Link: https://apps.apple.com/us/app/digital-atlas-ancient-life/id971829286
  25. Fossils?

    I'm very new to fossil collecting and would like to check if these rocks are fossils. My apartment was built in the 80s and is currently undergoing massive construction due to the rapidly deteriorating structure of the building. I was given permission by strata to collect a few rocks from the discard pile and I came up with these. https://docs.google.com/presentation/d/1l7M5NQVfFNXUXIxwqfopnE_wnq1kCiijePd5yEZRyRI/edit?usp=sharing
