  1. 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.
  2. 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.
  3. Majungasaurus tooth

    From the album Dinosaurs and Reptiles

    Scalebar 1 cm. Thanks to @paulyb135 for this awesome tooth!
  4. 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:
  5. 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.
  6. 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.
  7. 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.
  8. 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..
  9. Theropod IDs

    This is a follow up from another previous topic I started regarding some a past purchases of mine. I thought would be helpful to me and others to post here. All feedback appreciated. I stopped by Trenton state museum recently and David Parris generously helped me out. We ID’d these fossils together. I purchased a fossil sold to me as an allosaurus pelvic bone. I wanted to take it to a professional to see where it could fit, so David seemed to be the right guy. The fossil is fragmented, so from just looking at it, it’s hard to see what it could be period. But if you take a closer look in comparison with another theropod, it becomes somewhat clear. In order to figure out if the fossil was theropod, we took it over to the famous fighting Dryptosaurus skeletons for comparison. He figured it would be a pretty good match because of the size similarIty. He said it’s probable that it could be allosaurus. This is a pic of David with the fossil vs Dryptosaurus
  10. Theropod phalanx toe bones?

    Hi, I have these two toe bones from the Kem Kem. Was wondering if they belong to a theropod or something like a crocodile. The yellow one (1.3 inches) i believe is theropod, but i am not sure about the red one (1.7 inches).
  11. Theropod lower left jaw?

    Hi, I saw this for sale, apparently a lower left jaw of a small theropod dinosaur. It is 12cm long and from the Kem Kem beds. It also apparently has predation marks on it. I wanted to ask if indeed this is a theropod lower jaw or if it is something else like a crocodile jaw. Also the description says it is probably from an Abelisaurid, is it possible to narrow it down to family level?. Thanks.
  12. Tarbosaurus Tooth?

    Saw this tooth online recently, it already sold but it was listed as a Tarbosaurus Tooth but it reminds me more of a carcharodontosaurus tooth but then again I am unsure nor familiar with tarbosaurus teeth, what do you guys think? I have included all photos in the listing.
  13. Theropod bone

    This hollow bone was found in Carter County, Mt in the Hell Creek. The piece measures almost exactly 10”. Any idea what it is and/or what it belongs to?
  14. Theropod tooth

    What would this theropod tooth be its measure .7" and its form Two Medicine Formation.
  15. I purchased this from a seller months ago and wanted some insight. The seller bought this from another person who found the fossil itself. However, the seller says that 1, or 2 of the grallator tracks may be exaggerated or not tracks. It seems to me that the Eubrontes track is indeed authentic but I wanted to know what you guys think? These days people scam all over the Internet, but I have faith that the seller was truthful. Thanks in advance for feedback.
  16. Nanxiong Dinosaur Eggshell

    I have a large group of dinosaur eggshell fragments from the Nanxiong Formation of China. As they're isolated fragments I know its difficult to narrow them down to any particular oogenus, but I was wondering if it is possible to say anything about them just by surface texture alone? From what I can gather, eggshells with nodes and ridges from this formation would indicate a theropod eggshell, where as the smoother eggshells are more likely herbivour (probably hadrosaur). I've added pictures of each type. I've struggled to find a lot of detail on Nanxiong eggs which isn't behind a paywall, but what I have found is that there are three types of eggs described: Oölithes spheroides Oölithes rugustus Oölithes elongatus From what I can tell, spheroides is the only egg with a smooth shell and is believed to belong to a hadrosaur. The other two have more heavily textured shells and belong to theropods. I'm planning to sell some of these, so just wanted to double check my assumptions are correct. I also thought it'd be good to clarify, as it's hard to find out a great deal about these eggs online.
  17. Jurassic Footprints on the Isle of Skye

    Some cool findings from the Isle of Skye: http://www.bbc.co.uk/news/uk-scotland-highlands-islands-43620237
  18. Hi All I am open to trading my following theropod teeth. I have attached a couple of images of each teeth along with info on the size and locality etc. Please PM me for more info and images/offers if interested. EDIT - I am after other theropod teeth in return Paul
  19. Triassic Therapod Bone

    I found this piece of bone about a month ago and didn't really know what I was dealing with until I started prepping it out. I know that it is theropod based on the hollow structure, this should be at least somewhat visible in the photo of the broken edge. It came from the Redonda Formation in Eastern New Mexico where theropod remains have been found, but nothing identifiable to species. If anyone here can identify the species that would be fantastic, but I really just want to know what bone it is. My guess is the end of the pubis or ilium, but I was hoping for some other opinions.
  20. Hi All, im currently looking for some of the more rarer/hard to obtain theropod teeth to add to my collection (not the types like T. rex, carcharodontosaurus, nanotyrannus, albertosaurus etc) and have some teeth myself I’d be willing to trade. Please view my post in the member collections section (my small theropod teeth collection) and if you have any theropod teeth or are interested in mine we could maybe come to a deal. Please PM me if you potentially have any teeth for trade and we can go from there. Thanks Paul
  21. Hi All, I'm new to this forum and thought I'd send over images of my theropod teeth plus one extremely impressive sauropod from Madagascar. Hope you like them! Paul
  22. Kem kem vertebrae

    I bought this partial vertebrae about a week ago from a moroccan dealer for a very good price (I'm currently trying to identify many vertebrate fossils from Kem Kem, and this is somewhat a pause between two spinosaurid caudal vertebrae and a very big crocodilian mandible articular bone). Since many of you are way more experienced than me regarding moroccan vertebrae, I'm searching for more opinions. This small/medium sized specimen lacks most of the processes, but has some recognizable elements. It is laterally compressed and has a small keel running in its ventral region. I identified It as a caudal vertebrae, and the dealer told me it was a theropod. I don't think he had the skills to seriously identify anything, and I can't understand if It really is a theropod or a crocodile.
  23. Theropod tooth from Kem Kem

    I recently received as a gift this very small theropod tooth fragment from Morocco. I labeled it as Theropod indet., but I'm searching for a possibly more specific ID. In my opinion it may be a 2 cm broken tip of a small tooth from a Carcharodontosaur, but I also thought of the Abelisaur possibility. I tend to ignore the relatively unknown Deltadromeus and the hipothetical dromaeosaur, given the lack of good material, but I'm open to suggestions. Here you can see two focus photos of the serrations I took with a small digital microscope. As you see, there is a slight difference between the two sides. Still001.bmp Still004.bmp
  24. Theropod jaw section ?

    Would this be a theropod jaw section its was found at Judith river formation.
  25. Can across this one recently on our favorite auction site, a torvosaurus tooth from colorado. Though with no intention of buying especially at the high price tag it is at I have my suspicions, the seller claims it its 100% no repairs or restoration. Looking at the pictures I highly doubt it as it looks extremely repaired to me and some of it especially in the picture zooming into the tip reminds me of the little air holes found in fake cast trilobite. Idk how much is repaired or even if the whole specimen is fake, I'd be interested to hear what you guys think. Definitely a gigantic red flag to me.
