  1. Can someone help me out? Do I have a dinosaur tooth fossil? What is this? It was found in Northeast Arkansas, USA
  2. Hi, several years ago, I was hiking a canyon about 25 miles south of Moab in a broad canyon at the base of Moenkopi, Chinle (Triassic), Wingate, and a bit of Kayenta (Jurassic). I found this bone in an ephemeral stream that ran through the canyon and have been curious. Anybody have ideas? It is unlikely petrified wood which is extremely prevalent in the area.
  3. Hi All, First time posting! I need help with a fossil I found in the Hell Creek Formation of Harding County, SD this year. At first I thought it was a piece of Triceratops frill, but the more I prepped it, it appears to have edges with bone surface most of the way around it. If it was a piece of frill, I would not expect the edges to taper off (unless it was from a juvenile I guess). If it is a scute then it is absolutely huge and not like anything I have seen before. Hopefully the fossil community can help shed some light on this mystery. Any photos or links to reference other fossils would be helpful as well. Thank you in advance for your help! - Ryan
  4. Hey there I wanted to introduce myself because I'm completely new to not only this forum/website but also entirely new to any field even remotely related this sort of stuff. Many many props to you pros on here like paleontologists, archaeologists and scientists because I would consider myself to be a fairly intelligent individual in general, but trying to self teach about fossils when you don't know the first thing is not the easiest lol I've always been pretty outdoorsy and love the idea of fossil hunting or rockhounding (new word recently added to my vocabulary). It wasn't until recently that I moved to one of the most perfect places for it... Northern Colorado. To be honest though, it still took a few years after moving here before I had the slightest clue of what amazing things are waiting to be found. Even still, I feel like I'm just barely cracking open the door to it all. In the past two or three years I've gotten more and more fascinated with Mother Nature and her ability to create things far more beautiful than I could even imagine. For the most part I've collected cool rocks I've seen here and there but because I've got an 8-year-old that loves to follow suit, it can be tricky to remember 100% where these rocks have come from. I can tell you for sure most of them if not all of them I would bet money came from the same place which just happens to be what I would imagine is as perfect as any for something like fossils really be at. So I've gone back and forth saying that it's totally possible to find a kick butt fossil but then I tell myself there's really just no way I'd be lucky enough and all I've got is a really pretty Rock I can put my garden. In the back of my mind I've wondered though for a long time now and so I thought that I'd come on here and ask for some advice from some of you guys if you wouldn't mind. I'm making three posts of my number three favorites I think is what I'm going to do and then cross my fingers. I'll expect there just rocks for my garden and hope for the best. If you could please let me know if you have any idea for sure if this might be any kind of a fossil or even a sOr even maybe a semi-precious Stone or interesting mineral. Anything would help at all and I do think you had a Time for your time

    Is this Deltadromeus? Help please tell me

  6. Fast. Intelligent. Deadly. The "Raptor" is perhaps one of the most famous dinosaur today thanks to Jurassic Park. To many people's surprise however, raptors are heavily feathered and nimbler than movies would have you believe. The Jurassic Park Velociraptor was merely the size of coyote in real life! In fact, their proper family name is 'Dromaeosaurid'. The largest species was Utahraptor, and it grew to the size of a grizzly bear! Dromaeosaurid fossils have been found all over the world. They first appeared during the Cretaceous, though isolated teeth have been found in the mid-Jurassic. Allow me to present my humble collection of Dromaeosaurid teeth. First up, from Cloverly Formation, one of my pride and joy from @hxmendoza A dromaeosaurid from Aguja Formation. I am seeing more Aguja fossils showing up, but dromaeosaurid teeth are still rare. Now, for the dromaeosaurids from the famous Hell Creek Formation. Some of them probably lived alongside T. rex. A big shout-out for @Troodon for getting me started on dromaeosaurids with this very first Acheroraptor!
  7. Dear dinosaur egg collectors, after buying my first spinosaurus tooth some weeks ago, I decided to look for a oviraptor egg. First I started reading threads in TFF where experts give hints to detect fake eggs (thanks for sharing your knowledge). Then I have read several threads where people ask if the eggs are real and I think I can detect most of the fake eggs now. But in this particular case I'm not sure if the egg below is real or fake? The egg shape is pretty wide from one angle. The shell is very complete and from my point of view the texture and pores continue after a crack in the shell. What do you guys think? Thanks for helping. Max

    Unknown fossil found on on beach

    We had a big storm on the Pacific coast of Baja California Mexico and there are a lot of fossils and native American artifacts that were exposed due to beach erosion , and I was hoping I could have some help ID some of the items. Fossilized: Eggs, crab, shells,bones, wood? This one is the one I can't figure out at all, it very heavy
  9. My boyfriend and I were walking along the railroad tracks down by the Mississippi river in Davenport,Iowa when my boyfriend happened to look down and see this rock or fossil whatever it may be were curious to find out we done some google lens searches a got a couple ideas but would like some help figuring it out
  10. Hello there! I'm collecting fossils since I was a kid and I have a question, so I hope anybody can help. I bought a fossil years ago at my local fossil and mineral fair in Germany from a maroccan trader. It should be a Spinosaurus vertebra. But I'm doubting about the authenticity. It was quite cheap. But it's a real vertebra? (and even from Spinosaurus?) Thank you! greetings, Lilian

    Micro Raptor

    I have some weak terrible pics of it, but I think this is a micro Raptor from the Triassic period, size of a cat, first time a bird evolved to dinosaur. I think it's curled up in a ball and died sunk to the bottom of the what use to b ocean for millions of years and was embedded in sand and limestone combined with the water replacing the nutrients of the fossil made it well preserved, similar to the way most matrix would house dino fossilis, except this isn't digging it out of a rock quarry somewhere, this was just a Rock at the bottom of the bottoms in a creek.
  12. Hello, some time ago I found a quite interesting fossil. The seller claims: This is an authentic Spinosaurus Aegyptiacus vertebra Measures about 30 centimeters Location: Maroco Upper Cretaceous Approximately 10% restoration What do you think about the fossil? Best regards
  13. Hi all, We were in the Yellow Cat/Poison Strip area this summer and came across what we think might be a dinosaur bone in the Poison Strip sandstone layer. We also found agate/jasper. Trouble is, the “bone” is an unusual shape and the petrified wood for the area supposedly has lost its grain structure, so I’m not sure what to say. Wondering if anyone else can chime in about these? thanks, Lloyd

    A Physicist's Collection

    While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.
  15. Here is some of my first 6 months of fossil collection ! ( some still in transit oversea ...)

  16. Hello to everyone! This is my first discussion on this forum. I have just started to collect dinosaur fossils and I wanted to learn from all of you. Specially to identify a real fossil from a fake one, if that is possible. I have found an interesting fossil that I would like to purchase if it is authentic, but I have several doubts. The fossil is an Iguanodon Jaw (see pictures attached) discovered in Isle of Wight, UK. The dealer says that this bone belonged to an iguanodon that would have lived approximately 120 million years ago. They also told me that the jaw has been restored from two fragments that had broken naturally; both these pieces are associated and from the same animal. What do you think. Any clue would be appreciate. Thank you so much!!
  17. Hi I need help ID this bone. Location : Carter country , Montana: Hell creek formation it is quite small and hollow.. May be from limb bone of theropod dinosaur ? i am not sure pls help. thank Guns.

    Possible sauropod femur upper end

    I bought this agatized dinosaur fossil at a rock shop in Indianapolis about 4 years ago. It is agatized and it was at risk of being bought and sliced up. I am glad I rescued it. It has an identifiable shape. The attribution was only that it came from the Western United States and that it was a plant eater. It is probably from an old collection. It weighs over 90 lbs. It is wrapped up at the present time in tarp material because I moved in 2018 and I have not unwrapped it yet. I am thinking possible sauropod femur upper end. I can get more pictures and measurements when I unpack it.

    Hell Creek Theropod Tooth- Acheroraptor?

    This is a .35" theropod tooth from the Hell Creek formation, Carter County Montana. It is a really pretty little tooth for sure and it would look great in our Acheroraptor display. I believe I see the ridges that are diagnostic to that species, especially in the first picture. I wanted to run this by the forum to be sure I am seeing what I need to see though.
