  1. there is a new paper (a very short one, only a drawing with explanation) about a controverse theory: did dinos really exist? Famous Prof. Ferrington explained his theory at the annual meeting on the society of vertebrate nonsens last week I am allowed to post a pic of this event! Delicious!!! e.g. the blue marked one, thats me! First lane, first info!!
  2. Hello! I came into a ton of fossils well documented from the 70s 80s and 90s. I haven't gotten through half of the boxes. It's pretty incredible!

    Introduction

    Hello everyone. My name is John and I recently graduated with departmental honors in Paleontology from the university of Oregon. I regularly collect from the Astoria formation of the Oregon coast and produce replicas of specimens collected there. I'm currently trying to get into graduate programs. I have a few research ideas relating to paleoecology of dinosaurs and the functional morphology of various features seen in dinosaurs and extinct mammals. My main interest is dinosaurs, however my research currently undergoing peer review relates to how ecology, diet, and body mass drive reproductive strategies in extant carnivorous mammals. I currently make fossil replicas using an eco friendly plant based mold making compound that has a low melting point. This material can be melted down in the microwave and poured to produce molds. The benefit to this is that as molds degrade or get damaged they can be broken down and the material reused. I believe I'm the first to use this method of fossil replication. I've attached a section from the left dentary of an Albertosaurus that I replicated using this mold making material.

    Hadrosaur foot bone?

    Hello everyone. I was wondering if anyone can confirm or deny my ID on this fossil. My father in law found this in Montana when he was 16 along with associated bones. Some of the bones have dissolution features on the surface, but this phalanx is in decent shape. I identified it as a hadrosaur assuming Cretaceous age, but don't have much information on where it came from. The proximal end of the bone shows a clear darkened band where cartilage was once present, but rotted off. The notch on the proximal end of the bone makes me question my original identification. The bone is good sized and the proximal end shows a bumpy texture which indicates the epiphyseal plate may have detached, though it's hard to say for sure given the clear dissolution features on the surface of some of the other bones .I've also included a photo of the end of what I'm thinking is a limb bone if that helps.
  5. New here, love fossils. My collection in attached images. Coral and others I can not identify. Beautiful pieces.

    Kem Kem dinosaur collection

    Hi all! The past year, in the little spare time I had as a father of a 1-year old, I made illustrations of Moroccan dinosaurs on my iPad. I have shared some of these on this forum before, but I made some changes (hopefully improvements) to most of these, and some of them I have not shared before. The animals are all based on the designs of the Kem Kem dinosaur poster I made last year. Here is the complete set: Spinosaurus aegyptiacus Deltadromeus agilis Carcharodontosaurus saharicus Rebbachisaurus garasbae Rugops primus Some dromaeosaurids Some sauropods

    Hello from Tennessee!

    Hello, everyone! I am a 34 year old married female that loves everything about rocks, fossils, and gemstones! My husband and I have an extensive collection of all varieties of just anything we thought looked neat or different. My husband recently started working on a house his mom bought and under it is a root cellar with a rock "wall" that I've been allowed to dig in .. y'all, I can't wait to show my finds off. I am certain (although I'm definitely also not sure 😃) that we have stumbled upon something amazing! Hint* dinos and gold/silver!

    Christmas present perhaps?

    Ok yall. So there I was minding my own business looking for arrowheads and something catches my eye. Initially I thought it was a pestle until I got ahold of it. Then I thought maybe that's a big egg for breakfast. So while looking around for pottery and such a noticed something else strange . After I washed it off I could tell it was a skull with tissue surrounding it almost entirely and a sharp claw. I checked around for a bit then left . I'm headed home for the holidays and the skull of the dinosaur is riding shotgun! I've started calling him Jac, like Jack without the k. What do I do now and who do I contact? I'm the only one who knows where it is so that's a plus. On one side of the head you can see teeth. And I have no idea what that horn looking thing is. I found way further down .
  11. I've heard many times that the Ankylosaurus tail club is capable of breaking bones, and it certainly looks capable of doing so. However, is there any estimate in numbers that represents the force this weapon could exert?
  12. have got some secret information, better, seen it at FB They are back!!! (4) Facebook
  13. Here by I want you to share my fossil dinosaur collection and keep updating it! So lets start off by showing my recently aquired Spinosaurus indet. tooth from the KemKem Basin, Taouz Morocco. It measures 4'51 inches. Really like the colors and detailed preservation. With serrations still visible.

    Western Adventure Part 6

    One week fossil collecting trip out west, my sixth time in the past six years. Flew into Denver. Rented a car and headed down to Castle Rock where I spent the night at a motel. Next day drove up to Florissant Fossil Quarry. It was Wednesday and they're normally closed during the week in September, but I made special arrangements for a few hours visit. Compared to my two previous visits there, didn't do as well. The other times, I was there for the whole day, this time was just for three hours, and they had had a considerable amount of rain recently and so the shale was more crumbly and more difficult to split. Here are some of my finds. Plants:

  17. There is an isolated exposure of the Morrison formation nearby the area I have visited to hunt fossils the last few weeks. The shape is an elongated oval and measures 1.15 km wide X 3.75km long. This image is a small section of it. My question is this: Would it be worth exploring, scouting, hiking this area for invertebrate fossils? It is on BLM public land but keep in mind that vertebrate fossils are strictly off limits for collecting. The only reason I would even consider visiting it would be to hunt for invertebrate or plant fossils. The majority of the area surrounding this "island" of Morrison formation is Cretaceous period with the Juana Lopez Member of the Mancos Shale where I'm finding 4 species of ammonites. In my mind the old adage : when on a fox hunt, don't stop to chase rabbits...seems to apply to my question and for that reason I have yet to visit the Morrison formation spot. This case the fox is Ammonites and the Rabbits are dino bones, teeth, etc. It could be anxiety causing at worst and finding some nice invertebrate fossils at best. The anxiety being walking right past exposed bones, carnivore teeth, etc... which I wouldn't touch nor even photograph. The temptation to share would be another facet of the anxiety. Like - "Wow! I found Allosaurus teeth this weekend at ________ down in the Utah desert!" Wiki says this about the Morrison fm fossil content : Along the rivers, there were fish, frogs, salamanders, lizards, crocodiles, turtles, pterosaurs, crayfish, clams, and mammaliforms. The dinosaurs were most likely riparian, as well. Hundreds of dinosaur fossils have been discovered, such as Allosaurus, Ceratosaurus, Torvosaurus, Saurophaganax, Camptosaurus, Ornitholestes and several stegosaur species. A satellite view of a section of this Morrison fm "island"... The Junipers are probably 10 to 15 feet tall and a similar diameter.

    Dinosaur leg bone

    Found in the badlands of Alberta. I put it in my hand to show you the size. If anyone has any idea it would be greatly appreciated.
  19. Tj1977

    Need help to identify this.

    Found in the badlands of Alberta. I put it in my hand to show you the size. If anyone has any idea it would be greatly appreciated. To me it looks like a tail vertebrae but not sure from what.
  20. Hi. Thanks in advance for help from anyone. I recently bought these bones from someone with access to Bone Cabin Quarry, I am 100% confident these came from there. I can tell that some look like limb bones, #3 looks to me like part of a sauropod vertebra (but I could be wrong). I am fairly new at this. The person said the other Jurassic dinosaurs from the general area included Sauropods: Diplodocus, Camarasaurus, Apatosaurus, also Allosaurus and Stegosaurus. There are 15 bones in the photos, numbered 1-15. If anyone can tell me with any reasonable confidence about any of these, and how they know (I want to learn), it would be a valuable learning experience for me. I forgot to put in a ruler, but the box is 16" by 12". I do appreciate it! Gordon

    Two sauropods in a misty forest

    A digital illustrations of two sauropods. One of them represents a titanosaurian, the other a titanosauriform. This is part of a series of illustrations related to my Kem Kem poster.
  22. Hello everyone i just joined, i got a question are these real spinosaurus claw? (Thumb claw) found it on a website that was registered to AAPS
  23. Hello everyone Below are a few photos that I'd like some IDs on (if possible) from my trip with Paleo Prospectors to Garfield County, Montana back last month. We were fossil hunting with the ranch owners permission on private land in Hell Creek exposures. Row 1-Likely theropod/raptor toe bone and two theropod/raptor broken limb bones? Row 3-Small bones with odd texture/shape Row 5-Small broken limb bones? Row 7-Small crocodilian vert and small fish verts Thanks for looking. Feel free to request more photos (clarity, different angles/sides, etc.) if you see something odd or cool. Also found some nice teeth (likely nanotyrannus, ceratopsian, and gator) and a bunch of other cool bones. Can't wait to head back with them next year.
  24. Hello everyone, I'm going to be in Alberta soon and I was hoping to do some fossil hunting. I read on a previous post to this forum that dinosaur fossils can be found in the Horseshoe Valley, but I was wondering if anyone has any other suggestions near Drumheller, or if they could provide any tips for this locale. I'm aware of the laws regarding fossil collection as well, all specimens will be catch and release. I'm just trying to fulfill a dream I've had since watching Jurassic Park 20 years ago haha. Any tips would be greatly appreciated.
