I have a couple riker boxes of a few dinosaur teeth. Nothing super high quality; I enjoy a variety of teeth and was on a budget so I never looked for the highest quality of teeth to buy. I'm happy with a nice representative sample of the animal. I've moved away from buying many specimens now as I'd rather go out and find my own at some point, but I bought these years ago and I'm very happy with the diversity they represent. Plus as I teach geology, they are great teaching specimens for the kids to. First up is my collection of Cretaceous North American teeth from Hell Creek, Lance, and Judith River Formations. Most are dinosaurs, though there are a couple other fauna represented here to. Probably one of my favorite teeth from this box is the acid etched raptor tooth. Though I do really like the JR tyrannosaur tooth as well (I watched that one sell for more than I could hope to purchase, but it was returned as it splintered during shipping. So I bought it as a short prep project for cheap. I never filled in the cracks as I prefer most things unrestored).

Hello all, I was waiting a while to show my ever growing collection until I finally got this new shelf. I wanted to paint it to look similar to my other shelf, install these neat colour changing lights, organize things and move everything...then take photos! I had stored everything in my bedroom for a while but now everything is front & center for visitors. As has has been made obvious by my many ID posts and couple threads in the, “fossil hunting trips” section, I live in a fossil rich area have access to much land to collect from frequently, so I will use this thread for updates with future finds. I’m very proud to say that much of my collection, mostly the dinosaur stuff, has been found by me rather than been bought, though there is a lot of money invested here. If you would like more or better pictures, info or would like to help me ID anything in this collection that I’m unsure about (I’m severely lacking in physical labels at the moment) don’t hesitate to ask.

Hi all, I'm recently retired and I live in NW Wyoming and was wondering if anyone could shed some light on these specimens? Im particularly interested in the big rock/fossil? at the top of the picture. I found all of these on the surface in a sandstone, drab mudstone formation. Possibly Eocene, Paleocene time frame based on some quick geologic research. Looks like a foot to me but I suppose it could be about anything. The other items were found in the same area with the larger one. The area would have once been the near the edge or boundary of Lake Gosiute an/or the inland seaway I think. I have enjoyed reading some of the posts, seems like a good forum! Thanks, WyoProspector

Dear TFF-members, Can anyone help me identify the fossils in the photographs below? I have trouble identifying the concentric patterns that are visible on these (apparently hollow?) shell-like fragments. They were found in the Pyrenees, Spain. The formation in which they were found is Mesozoic in age, most likely Jurassic. Note these are outcrop photographs, so I cannot make additional images to aid identification, unfortunately. Thanks for any feedback you may be able to provide. Kind regards, Tim

Ok, I just came across articles about soft tissue remains, apparently including some form of degraded blood, in a mosasaur. That of course, brings up the T-Rex soft tissue found, to me. I seem to understand what I keep reading, but I can’t help it, again I find myself thinking...Really? C’mon, REALLY??? Am I just misinterpreting the whole thing, or is there actually real, true, gen-u-ine unfossilized/in mineralized, preserved soft tissues and blood remains in these 70ish million year old “fully” umineralized animals? ...............HOW?????????????? How, when the rest of the animal, soft AND hard tissue has dissolved away so long ago, can any soft tissue remain? How do only small areas of the tissue remain? If conditions are so, that areas of soft tissue/blood residue remain, how do just small patches remain, but the parts immediately surrounding the patches have long since dissolved away? Conditions inside an intact bone, or intact stomach cavity, should be stable, shouldnt they? Not different from one centimeter to the next, especially so different that one spot dissolved dozens of millions of years ago, and the spot touching that one is still just sitting there, relatively preserved?

Today, instead of bemoaning the paucity of marine cretaceous rocks in my state, I reframed the situation as follows: "In the Cretaceous, most of Missouri was not ocean but land, with lots of exposed limestone that dinosaurs were likely walking around on." This led me to the following question: Do we have no fossil examples of dinosaurs that fell in sinkholes / caves / paleokarst and were preserved there, perhaps discovered during quarrying of the limestone? We definitely have such examples for fossil mammals, reptiles, etc., including Pleistocene (Ocala), Pliocene (Pipe Creek Jr.), and Miocene (Gray Fossil Site)... So why not earlier? Why not dinosaurs? Surely there were paleokarst processes in action during dinosaur times. As possibly useful information, there was definitely regional hydrothermal activity here in the Mesozoic, based on the Jurassic emplacement age of southern Illinois fluorite.

Hello everyone, I have decided a while ago that I would focus on collecting Paleozoic material, because of this there are quite a few fossils I have that I purchased a long time ago and do not have an interest in keeping, these guys are not that special and I am not looking for much of anyone even does want to trade with me, but I do prefer Paleozoic material. I will post what I have here. 1.Lebanese shrimp fossil Cretaceous GONE/TRADED 2. Geocoma carinata I believe from the Solnhofen 3. Chunkosaurus 4.some cretaceous teeth, spinosaurus, Squalicorax, scapanorynchus, enchodus 5. Some gastropods 6.otodus obliquus Morocco eocene

Help request! Seeking diagram of scleractinian architecture through time
pefty posted a topic in General Fossil Discussion
I recently saw a wonderful diagram showing the fossil ranges of various scleractinian coral architectures, or at least the ranges of genera typical of those architectures. But now I can't seems to find it again... The diagram included images of the various coral growth forms and was simpler than but otherwise similar to this: If anyone knows where I might have seen such a diagram, please post the url here -- thanks! -
Hi I was just at my aunts house and in her house I found a ammonite I asked her where it was from and she said she got it in Cuba which made me wonder what creatures lived in Cuba in the Mesozoic I found out In the Jurassic there where Pliesiosaurs, Ichthyosaurs and ammonites and lots of pterosaurs also there has been some dinosaurs too which surprised me because I thought Cuba was under water there’s a few remains of sauropods a Camarasaur and a Diplodocus like sauropod some more fragmented Sauropod bones and some bones of a unknown Saurischian also some unknown reptile bones have been found too I hope this helps with the Mesozoic creatures of Cuba this is my first informational post Thanks!!

so i went to Orlando Science Center today for the Dino Digs exhibition but in Jurassic Ridge dig pit area i know that there is a Camptosaurus, Camarasaurus, Ceratosaurus and a Stegosaurus, but there is some species and genus of dinosaurs and other animals that i dont know what there like take for example the turtle shell, the alligator crocodile like animal fossil, the ankylosaur like fossil and that bone that i dont know what species does it belong to and that nest that i don't know which dinosaur does it belong to.

Hey Everyone - I hope someone can provide some insight and help me identify this fossil. I would really appreciate it! I found this strange looking tooth (at least I think it is) a few years ago in San Antonio, Texas. It feels and looks like a rock as far as texture goes but it's shaped very similar to an animal tooth. I've attached photos for reference and labeled each one: Front Back Side Front Height - 5 inches (12.7 centimeters) Front Width - 4.5 inches (11.43 centimeters) I've also attached a Geology Map of Texas which outlines where rocks of various geologic ages are visible on the surface of Texas today. On the map, I circled in yellow the location of where San Antonio, Texas is for reference. Hopefully it can provide more insight for you. I'm not even close to a geology expert but limestone is very prominent in San Antonio. The city is also home to The Edwards Aquifer which may or may not be useful. I'd be happy to answer any questions and I can also take additional pictures if needed. Looking forward to hearing back from you all!

I found this near a river in La Matea (Jaen, Spain) the zone is predominantly mesozoic and the rock is limestone. I'm not sure if it's a fossil or some kind of formation. I have two similar specimen, is like a cylinder that goes from one side to the other of the rock, in one of the images I've partially removed some of the rock. Thank you.

Found today on the English Yorkshire Coast ( Runswick bay). At first i thought it was maybe layers of a type of fossilised plant but I cant find anything to match the markings on this. Completely baffled by it. Looks very cool though. ID help, please?

Hi- I found this today at Lake Benbrook, Tarrant County Texas. I was looking for newly exposed large ammonoids. I believe that it is possibly from the Woodbine formation because I also found some nice Gryphaea- looks like maybe Parasmilia but it also looks like has a shell- 3.5 inches x 1 inch. Your expert help appreciated- Thanks-

Hey, a question I have always wanted to ask is about dinosaur relatives, more specifically what do we mean when we refer to two dinosaurs as cousins ? Do we mean that a kind of dinosaur(for example baryonyx ) lived in an environment but at one point a group got separated by land and this group got to live in another part of the world so that group resulted in adapting to another environment and becoming a different dinosaur (for example spinosaurus ) or do we mean that a dinosaur is an ancestor of another dinosaur (again for example baryonyx evolved into spinosaurus)? This may seem like a really basic question to ask but I haven't really been able to find an answer so if someone answered it would be great.

I watched a show on PBS last night, "When Whales Walked: Journeys in Deep Time." I just happened to notice it on the guide about 45 minutes before it was on. It is actually about more than the evolution of whales, the group having four-footed Early Eocene ancestors. There is a long segment roughly twenty minutes long each on crocodilians, birds, whales, and elephants. I thought it was a good show overall with interviews of researchers I know from their technical articles ( Hans-Dieter Sues, Philip Gingerich, Emmanel Gheerbrant, Christian de Muizon). However, each segment was also a little light on content for the topic and one was especially unclear. The one on birds made it appear that Deinonychus was an ancestor of later birds. They should have showed a chart showing when it lived in the Cretaceous with Archaeopteryx and the Liaoning birds millions of years before. There was a quick view of a family tree that seemed to illustrate that but it went by in a second or two. The segment on whales showed a lot of footage of modern whales and some great background on the "first whale," Pakicetus, but it didn't show any of the whales described in the past twenty years. It just mentioned that there had been recent discoveries. I thought there should have been at least a quick look at Ambulocetus and a few of the increasingly more marine-adapted forms that lived before Basilosaurus. They pretty much jumped from Pakicetus to Basilosaurus to the divergence of toothed and baleen whales. I think they could have spent the two hours just on the whales just as the title of the show led me to believe. I liked the segment on elephants because just as I was expecting the show to skip the earliest known members of the group, they go to Morocco and then talk to Emmanuel Gheerbrant who described Phosphatherium, the first probiscidean, which is known from the same early Eocene phosphate layer as a lot of the shark teeth we see at shows are from. Other extinct forms were descussed as well. Here's a link that takes to an online notice and website: https://www.pbs.org/show/when-whales-walked-journeys-deep-time/ Jess

Hi everyone. This is my first request for an ID, I'm a complete newbie with limited knowledge but very eager to learn. This might be nothing, but I thought it was strange. Found loose on a Yorkshire beach (UK) unsure whether it was washed up by the sea or came away in a cliff fall. Area known for ammonites/Mesazoic/Jurassic finds. Measures approx 9cm in length, 18 cm circumference.

I believe these are parts from a crab I found in NJ, from what I see I think the large one is from the shoulder or bicep from a crab, is it possible to identify anything else about the animal?this side is fairly flat with the bottom edge protruding out.this side is round but in pretty bad condition.side view of the piece.

Tried my hand at two different styles of drawing an icthyosaur. Don't exactly remember the species I was going for but I remember that it and the fish are both from the Jurassic. this one is a bit more realistic. and this is a cartoony representation.

Howdy from the frontier country of New Mexico! I'm Tammy. I stumbled upon this forum while trying to categorize a very large collection of interesting fossil specimens collected in the mid to southwest of New Mexico, by our daughter Carol (an avid fossil collector). During her last visit we separated some of the largest specimens, revering some more than others, discussing the cosmos and the earliest life forms on planet Earth. We recalled that Carol collected rocks as souvenirs from vacations. On a vacation to Minnesota, Carol collected a '(flat) rock'; it was a decade later when she realized it was actually a prehistoric tool! I'm positive that's what started it all! I hope you can forgive our lack of 'technical' terms and a few run-on sentences now and then, as we attempt to analyze and understand this collection. I'm off to read and learn! Sincerest gratitude, Tammy
