  1. Worn Down Theropod Tooth

    A couple of years ago my grandmother purchased me this theropod tooth offline for a cheap price. The only locality given was Hell Creek, Montana. I took it to my local geology museum and one of the paleontologists who took pictures of it for me told me that the serrations were nearly identical, but he said that it is a dromaeosaurid tooth in his opinion. I think it could be either nanotyrannus, dromaeosaurid or maybe just a theropod indeterminate. It is very worn down. What do you guys think?
  2. Abelisaurid Premax Tooth

    A premaxillary tooth of an Abelisaurid.
  3. Juvenile Baryonyx fossil footcast. Only 8cm long. 135 mya. Bexhill. Sussex Add more later.
  4. Abelisauroid Vertebra

    A distal caudal vertebra of a theropod dinosaur. This vertebra is quite similar to Masiakasaurus from Madagaskar. So I've labeled this as cf. Abelisauroidea. There have been some reports that there are Noasaurids in the Kem Kem beds, so that might be a more specific possible identification. However at the moment just not enough is known about the Kem Kem fauna.
  5. Tyrannosaurus?

    Ok, here's 2 pieces. I think it's clear which are which, but just to be clear, of these first 4 pics, the 2nd picture for some weird reason, is of the 2nd bone, and the other 3 are of the 1st, and the rest of its pics will have to follow in additional posts. Of course I'm still no expert, but as some of you will know Ive been doing QUITE a bit of research on trex bones recently, and I have to say that from what I can see, to ME, who again, is no expert, they look like they fit, and I haven't seen anything that discounts that. Both from hell creek. <<As always, I very much want to hear what everyone has to say about it.....ESPECIALLY if u agree, but even if you don't too, of course:) A lot of what Iv learned recently and been pointed in the right directions to learn, is from you guys giving me your thoughts and ideas! If I notice something to debate, or devils advocate in people's ideas, its cause I'm taking it seriously. I worry I might sometimes come off as being stubborn and just disregarding things of people who's opinion is just not what I am wanting to hear.
  6. Hi all just wondering what the chances are of ever being able to own a carnotaurus tooth. it’s probably number one or two on my want list and I know they can’t be imported from Argentina but wondering how many people own them ( were they common when they were obtainable) and if you can see a way in the future if Argentina allowing these fossils to be sold once more. any help or info would be appreciated! Paul
  7. Vertabra

    Searching through some matrix I found this partial vertebra. Wish it was a bit more complete but maybe next one. This was found in marine sediment from near Richmond in Central Queensland Australia. It is from the Toolebuc formation witch is Cretaceous Albian about 98 - 100 million years old The longest length dimension is 6.5 millimetres so the animal it comes from must have been huge Also interested in where on spine this would have been situated if sufficient information can be gleaned for this partial. Thanks in advance for all input. Mike
  8. Always like to see discoveries of dinosaur material from the east coast especially from North Carolina. Here, the first definitive occurrence of a dromaeosaurid from the Tar Heel Formation is reported on the basis of a tooth from a fairly large member of that group. The tooth described in the paper is intermediate in size between those of smaller dromaeosaurids like Saurornitholestes and gigantic forms like Dakotaraptor. https://www.paleowire.com/just-out-a-giant-dromaeosaurid-from-north-carolina-cretaceous-research/ Paywalled paper https://www.sciencedirect.com/science/article/pii/S0195667118301253
  9. Hello forum, new member here! I have been lurking for a while and concluded that some of my Hell creek fossils are probably mislabeled. Bought them back in 2005-09 from a Danish collector. The three small theropod teeth were labled as follows: smallest one, at 11 mm long and 6mm at the base; Saurornitholestes. (Hell creek, montana) Second largest at 15 mm long by 8mm; Dromaeosaurus.(Hell Creek, Montana) Third one is labeled as Nanotyranus, but with a length of 15 mm and a 9mm base, it seems quite small. ( Hell Creek, Roundup, Montana) The middle tooth has faint ridges, the cam is not picking up, running from top to bottom (Acheroraptor?) Would love to hear your opinions on what these could be!
  10. Triassic Vert (Coelophysis?)

    Hello all, I just picked up this pretty vert and am not quite sure about the ID. The seller advertised it as Coelophysis, but it doesn't seem to be a match. It's from Bull Canyon formation, Quay County, New Mexico (Upper Triassic). It measures 2 1/2". The seller provided good pictures, so I've attached some of those. I can provide more and even take some of my own if needed! Thanks, and hopefully we can figure out an ID on this one!
  11. Organizing Collection/ ID Help

    Organizing my collection has been the tedious, but also a really fun process. I’ll probably continually posting here for assistance. When I’m feeling a little more confident about my ID’s, I’ll post it in the members collection section to share. I still have some fossils to prep, piece together, display, label, etc. and really fortunate that I have all of you helping constantly; it really speeds up the process. In another year’s time, I’ll be much more educated/ well rounded Some of my fossils are rookie purchases, so I’m just trying to make the best of it. The issue is , I think they’re pretty cool, but not sure if they are worth displaying given that they are bone fragments. I was thinking maybe in a riker...also the issue of labeling...Below are three separate purchases. Group 1: The seller sold these in fragments. Several of these pieces I glued back together neatly with Paleo bond. The seller must’ve used some kind of thick glue originally because there are some marks, but it’s no big deal... anyway these were advertised as Albertosaurus bones... when I asked the seller why he labeled it as such, he said because it’s very probable? I asked him for a coa, and when I received it, it only said Tyannosaur bones... so I’m going to leave it at that...because it’s indeterminable. Even back then I knew Coa’s were pointless, but I always like asking for one, because I feel like it could possibly put a little pressure on the seller to be a somewhat more honest like it did in this case...however in most cases sellers don’t care: Tyrannosaur bone fragments: Judith River Formation, Northern Montana The other small miscellaneous pieces I don’t think can be glued back...no fit or match, just associated bones...What would you label the fossil as, and are they worth displaying?
  12. Theropod Teeth and Claw Segment

    Forgive me, for I am new here. So I purchased these two teeth and a (ID’d as) crocodile claw segment at my local gem and mineral show for $10 each. These were identified by the director of my local geology museum as potentially being from the Lance Creek formation in Wyoming, but he said that I may need to wait for another paleontologist who works at Hell Creek to come back and take a closer look at the serrations. The second tooth, however, has the color for a Kem Kem specimen due to its reddish-brown color. The director was nice enough to take photos of them. I have more pictures of the teeth and claw segment that I’ll be uploading in the comments.
  13. Seller claims to have secured this in an estate sale. It’s on the pricey side. For me, it’s difficult to see any difference between this and an average spinosaurus tooth. The fossil is from moroccan sahara, says there is civil war in the tenere desert, and therefore collecting there is illegal due to current regulations. Thoughts?
  14. 2017 Wyoming Microsite Finds

    Last summer on my trip out west, I found these teeth at a Lance Formation microsite in Wyoming. Many of the fossils were found through splitting a yellowish-orange concretion filled matrix, while others were free from it. This site was on the same ranch where I found my theropod hand claw but in separate locality. It's rather late (EST) at the time I'm posting this but wanted to show some of the teeth I found and was hoping I could get some help identifying them. 1. Pectinodon bakkeri 2. Richardoestesia sp. (?) 3. Lizard/ Worn Herbivorous Dinosaur Tooth (?)
  15. Nice, cool big bone for sale from Hell Creek Formation Montana listed as rex, is it?
  16. From the dinosaur coast of Spain this paper addresses the remains of a very large Meglosaurid. Possibly related to the large Torvosaurus reported from Portugal Rauhut OWM, Piñuela L, Castanera D, García-Ramos J, Sánchez Cela I. (2018) The largest European theropod dinosaurs: remains of a gigantic megalosaurid and giant theropod tracks from the Kimmeridgian of Asturias, Spain. PeerJ https://peerj.com/articles/4963/
  17. I wanted to share some of my projects with all of you. A hobby and side business of mine is creating dinosaur sculptures. I do all different kinds of things aside from dinos too, but to keep it relevant, we’ll stick to the mesozoic Featured in my profile picture is my raptor created from scrap metal used to construct railings. I named him Bambi (ironically not a Bambiraptor). Probably more like Deinonychus, he’s a pretty big chicken, but you let me know what you think. As of now he’s my favorite creation, hence why he’s featured in my profile pic. Still trying to figure out the paint job. I wish he’d stop scaring all the birds and deer away...
  18. Hi, Saw this hand claw for sale and wanted to know if it is real. I am a bit suspicious because the tip has a different texture to the back half of the claw. Not sure if there is any repair/restoration but wanted to check to make sure that it isn't a composite. The claw is 4.8cm long and from the Kem Kem (this is the only information the seller has listed). Thanks.
  19. My Theropod collection

    Just starting to get into theropod teeth. Surprised this didn’t happen many many years ago as I was obsessed with Jurassic Park as a kid. After many a times searching on this amazing forum, stumbling across @Troodon‘s Jurassic threads and late night boredom searches through everyone’s favorite online auction site I decided it’s time to expand the collection. I’ve primarily been into shark teeth in my short time getting into fossils serious. I’ve had some stuff since I was a kid but a work trip to Charleston 2 years ago has led a new obsession that’s branching into others... Some spinosaurus indet that I got from the Tucson show a while back Carcharodontosaurus A raptor species of some sort Starting of with some Moroccoan stuff for now as it’s heavily available and not too harsh on the wallet. Really would like to get into some North American theropods but kinda clueless on where to start and where to purchase from. I don’t mind using online auction sites for the Moroccan stuff but I’m hesitant on the NA stuff in there. If you guys have any recommendations please PM me some recommendations. Thanks for looking and please feel free to share pictures of your collection with me.
  20. Majungasaurus tooth

    From the album Dinosaurs and Reptiles

    Scalebar 1 cm. Thanks to @paulyb135 for this awesome tooth!
  21. Chunky Kem Kem Theropod Tooth

    Hey folks, Thought I'd run it by the forum experts as to whether you agree with the Carcharodontosaurid label for my new acquisition (which it was sold as)? Locality is the usual Kem Kem beds, Morocco. Serration density- Mesial: 10/5mm Distal: 9/5mm Distal serrations run to the base, while the mesial serrations end about 3/4 of the way down the carinae. It's a chunky little thing, but I gather Carch teeth can occasionally be on the more robust side....but I'll let you judge: Side Views: Base: Distal: Mesial:
  22. I bought this specimen on eBay about 10 years ago, from a reputable seller who had a lot of other Hell Creek material. It was listed as a Tyrannosaurus rex tooth, from the Hell Creek Formation of Montana. It obviously has a lot of repairs and is quite fragmentary, but overall seemed to be a genuine fossil, and for the $350 I paid it seemed like a good deal. But recently, on closer examination, I got a little worried. There is no trace of serrations whatsoever on any part of the tooth, which seems odd- the only non-serrated large theropod teeth I know of are the spinosaurids, which this doesn't resemble overall (and which don't occur in the Hell Creek anyway). I guess what I'm asking the dino tooth experts here is a) Should I be worried about the lack of serrations? and b ) Is there anything else suspicious about this tooth? I tried to get different angles for the photos, but am happy to take more if that might be useful. Any help is appreciated.
  23. This is a great fossil forum. A wealth of information. Lots to educate the passionate collector. I want to share a few more of my latest finds with members of this fossil forum. I hope you all enjoy the pics. These are some of my best discoveries made in my Hastings Wealden bonebed collection this past week. First off is this lovely Dromaeosaurid tooth. It took me a few hours, but I managed to prep out both sides. My best find in a while.
  24. new paper on tiny Spinosaurus claw

    The smallest biggest theropod dinosaur: a tiny pedal ungual of a juvenile Spinosaurus from the Cretaceous of Morocco https://peerj.com/articles/4785/ Abstract We describe a nearly complete pedal ungual phalanx, discovered in the Kem Kem Beds (Cenomanian) of Tafilalt region, south-eastern Morocco. The bone is symmetric, pointed, low, elongate, and almost flat ventrally in lateral aspect. This peculiar morphology allows to refer the specimen to the smallest known individual of the genus Spinosaurus. The bone belongs to an early juvenile individual and it is proportionally identical to the ungual of the third digit of a large partial skeleton recently found, suggesting an isometric growth for this part of the pes and the retention of peculiar locomotor adaptations—such as traversing soft substrates or paddling—during the entire lifespan.
  25. Well, following up on my theropod ID topic... Really shocked...in under 8 hours, Tyrannosaurus rex expert Pete Larson gets back to me with this response regarding my fossil being T.rex or not...I guess after 20 buying mistakes, eventually good things do happen ...feels surreal... here’s his response to me: (last picture) Now officially one of my most prized possessions, and maybe the most for that matter..
