    Silurian Fossil Needs ID

    This is a fossil I collected at the Long Pond Road Site along the Erie Canal in Greece, New York. It is from the middle Silurian Rochester shale. Some interesting perpendicular lines can be seen along the edge of it. I have looked for other fossils similar to this one and have found nothing. The American dime is 1.8cm in diameter.

    Silurian Invertebrate Needs ID

    These are two fossils of the same species collected at the Long Pond Road Site along the Erie Canal in Greece, New York. They are from the middle Silurian Rochester shale. These were collected last winter, and I have since been unable to identify them. Both are no greater than 3cm in length. Some interesting fine detail is visible on the first specimen. The American dime is 1.8cm in diameter.

    Dappled find

    Hello everyone, I’m new here and I am from Louisiana. I have found many gorgeous rocks around my grandparents old home site. I’m hoping to learn what they are. What is y’all’s idea of this one rock?

    Is This An Egg?

    Hello! I am not a serious fossil collector, but I am always on the lookout for fossils when I am around exposed rock. I was hoping the members of this site could tell me if they thought this rock was a fossilized egg. I was struck by its shape and its texture. I photographed it in the Grand Canyon on the trail between Phantom Ranch and Cottonwood Campground. It measures about 5 inches squared. Thank you for your thoughts!

    Learning on the River

    Hello! I'm a novice looking forward to learning more about fossil hunting and paleontology. My family and I were wading in the river a while back and my sister-in-law found a couple of 'rocks' we thought might be fossils near my home in Southeast Texas. I sent pictures to a couple of professors and they told me that we appeared to have fossils but identification was difficult because the picture quality was poor. (My sister-in-law took the fossils home with her, so I only had a handful of pictures we snapped). After that, I got really interested in what type of fossils might be in my area, so I started searching the internet and this site to see if I could learn more. I learned that my area of Texas was home to Ice Age mammals, among other things. I was impressed with how knowledgeable and helpful everyone on this site seems. My husband and I have found a few more fossils in the river. I've cleaned them up and learned more about how to take better pictures for identification. I'm hoping to take some good pictures of our finds and post them on this site this weekend for help with identification. Thank you all for participating in such an educational and useful site. --Brandy

    ID HELP PLEASE!

    This was found near the Farmdale Geologic Exposure, and I am having a heck of a time identifying it; I'm used to your typical bryozoa, crinoid, and brachiopod - not this! The inner, u-shaped part looks biological, and is packed with a more clay-sourced material around it, and perhaps inside? I've taken numerous pictures to try to give a full look at this weird find. The outermost rock layer can flake off of picked. I'm not even 100% convinced it's a fossil, but i'm having trouble coming up with what in the world it could be. Please help me out!
  11. You thought I was done? NOPE! Here are some localities in the US. Some of these are going to take some searching for. http://fossilspot.com/index.html

    trying to identify another find

    The front, back, side and bottom of whatever this could be? I could not find anything to measure it with but for now hopefully the pictures alone help for the meantime. The shape of it reminds me of a bone for some reason so that's my guess as to what it could be; not quite sure of what this texture on it is though, i scraped a bit of it off fairly easily and it was dusty brown coming off of it, but not too hard when scraping the surface it barely had any resistance. I tried scraping the exposed part of my other find; the iron concretion to compare the 2 and the concretion was much more durable on it's exposed part to try ruling out if it is just another ironstone concretion. It was found in the same brook called "big brook preserve" in central new jersey in the united states. Another possibility that I've came up with is that this find might be a concretion but not nearly as old and formed yet. Right now it could be anything. Thank you to whoever responds and helps with this post; very much appreciated.

    Dinosaur Teeth

    Hello. I am considering trading for a few late Cretaceous-era theropod teeth from the American West (I think Wyoming/Montana) and would like some help confirming what they are. They are in ok condition, but I don't have any dinosaur teeth in my collection so I am very excited to bring these in. I'm not sure what formation they are from. I was hoping to narrow these down to a species, or at least get a second opinion. First one is a tooth that I was told is a tyrannosaur ind. Thoughts? I have been reading a lot of what @Troodon has posted so I am tagging him since he seems to be the resident expert. I will post pictures of the others as soon as my fellow trader sends me them. Thank you!
  14. Recently I took a trip up to central New Jersey in the US with my sister for our 2nd trip fossil hunting; at a place called “big brook preserve”. As I was sifting through looking at some fossils that I could identify such as shark teeth and fossilized poop with my very basic studying from the Internet and stuff I’ve seen on tv. She calls me over at something she had found while sifting through the dirt in the brook. Thinking that I’d be able to identify it for her I was stumped. it looks like it has characteristics of a fossil from what I think but with my limited knowledge and understanding I keep going back to the idea of “nah it can’t be” And thinking it’s just a cool rock. Either way the water seemed to do a number on this this find eroding it over the years. Also the finds in this brook are usually Cretaceous period specimens and the occasional dinosaur fossil is rare, and reptile fossils are a tiny bit rare too here I think. I have a couple pictures that I took that night when we returned home. I’ll take better lit pictures if these aren’t adequate enough, but the main question I have that’s been bothering me is; is it a rock or a fossil from something once living? Side note the front is slightly smoothed/curved and the back is mostly flat. Please and thank you to anyone willing to help. I’ve also taken the time since then to email 2 local universities for assistance too if that’s even possible.

    Fish tooth?

    I found this matrix containing something that reminds me of the fossilized fish tooth pictures that I have seen around on here. When I noticed this, I chipped this matrix section off of a larger shell hash plate containing mostly Turritella sp. and bivalves. Its original location is in Ellsworth county, Kansas at Kanopolis reservoir. Age of this matrix is Albian and it is from Kiowa formation-Longford Member. Length of this 'tooth' is about .25 inches/6.5 mm. Can anyone identify what it is? It is currently soaking in a bowl of water, I hope to remove more of the matrix off to get a better look at it. Do you have any advice/tips on how to do it without breaking the 'tooth'? As you can see it, it's very small and I have nearly no experience in prepping the fossils beyond the washing and brushing with toothbrush.

  17. Can anyone identify this what type of marine life this skull is part of? I found it today along the East Coast of United States - Atlantic Ocean Spoon in photo for scale. The strange up raised markings on top are perplexing. Type of Eel perhaps? It's wet from me rinsing it in sink. Thank you!

    Potential theropod tooth

    So I was walking in the river near my house one day and found what me and my friend think is a jeuvinile theropod tooth. Me and my friend are good with identifying dinosaurs, we love dinosaurs, but I just want to be sure. It's about 5 1/2 centimeters long, maybe 1/2 centimeter tall, and at the base about 1 centimeters thick. I found it in the Arkansas river right below keystone dam in Oklahoma, United States. It got dropped and broke into three pieces and that is why there are cracks in it.

    estate Sale - Hell Creek Theropod

    First post, but frequent follower of the page. I just came across a toe bone from an estate sale. It looks Hell Creek by the bone material and by what else was in the collection. It is definitely theropod. Would any of you be able to ID this? Any insight would be helpful. Thanks! Sean

    Found this weekend

    Found this weekend in my Dad's back yard in Tucumcari, New Mexico. This is the only piece i could find. Yet to find any info on this thing and never seen anything quite like it before.
  21. This was found on the Jersey Shore - a beach on the western Atlantic. I unfortunately don't have a scale, but it measures 3 inches x 4 inches (7.6 cm x 10.2 cm). Any idea what it is?
  22. Hey! I have kind of an odd question. I am purchasing a fossil for a friend as a birthday gift -- between a tip of a mammoth tusk, or a section of mosasaur jaw with teeth. What makes this unique, however, is that we are traveling to the British Virgin Islands (from the United States) for said birthday and I would like to be able to gift the fossil on the birthday instead of waiting until she returns home as we live in different states and I would only be able to ship it to her house and not be there. I am concerned, however, about bringing the fossils with me on the trip as I have heard nightmares about customs causing long hold ups or seizing fossils. Does anyone have any advice on this? Thanks!
  23. Cracked Pterodactyl Egg With Embryos Complete And Visible? At our favorite auction site, a seller is offering in several ads, these beautiful boulders that are no more than mere geological occurrences, which anyone can find on the edge of any river, as if they were genuine Pterosaur eggs ... But the Freak Circus does not end here, there's more! He announces as if these "eggs" had visible Pterosaur embryos. Can anyone see? But if you're a picky fossil collector who does not like rickety and scrawny creatures like the Pterosaurs ... His problems are over, because now he also sells boulders as if they were dinosaur eggs: How does he know what a Pterosaur egg is and what is a Dinosaur egg? Anyone have any explanation? A genuine egg of the Pterosaur is very, very rare, and is extremely different from these boulders that are widely being offered! That is, genuine Pterosaur eggs have shells, consisting essentially of an outer layer of thin and hard limestone, while under the shell was a softer membrane: And thanks to these meager but true discoveries is that we now know that pterosaur eggs were malleable, similar to the snake eggs of today: Unfortunately I can not reveal prices here, but believe me, these fake eggs do not cost anything cheap! So the high price is a great seducer, a real temptation for a novice and inexperienced collector, to think that high price means rarity, therefore, authenticity! The advice is the same as always, study on the subject so that the light of knowledge can dispel the darkness of ignorance.

    Fossil identification

    I found this as a child on one of the many adventures our family had across the United States, but do not know exactly where I found it.

    Is this a tiny baby bird fossil

    I have no idea what this really is. I found it when I was digging a new flower bed in my garden. It is from the east coast of the united states off of the coast of Delaware near the Atlantic ocean (I live less than a mile to the ocean). It looks like something to me, but are my eyes playing tricks on me? I can take more pictures. The rock sparkles, making some of the pictures hard to see, I picked the best I could.
