  1. Some very nice dinosaur material is being offered for sale but their identifications need some massaging. This beautiful tooth is being identified as Gorgosaurus from the Judith River Fm. Its a "Tryannosaurid indet. " since we cannot distinguish teeth between Gorgo and Daspletosaurus.. Looks like an anterior dentary position. This gorgeous rooted hadrosaur tooth is being identified has Lambeosaurus also from the JRF. Most seasoned collectors know its very difficult to distinguish teeth between different hadrosaur species. Quite a few are described from the JRF not sure if Lambeo is one. Best identified : Hadrosaurid indet. A Majungatholus tooth from Madagascar is also offered. Unfortunately the tooth is clearly not an Abelsaurid so it cannot be Majungatholus or properly called Majungasaurus. What is it I really do not know since very little is described from the Maevarano Formation. It also brings to question if the locality is correct. "This tooth was already posted on the forum" From the Judith River Formation the seller is offering this Troodon foot Claw. Only two photos were included in the listing so it was difficult to tell but initally it does not look like one more like an Oviraptorid claw. If you are interested I would ask for more photos so we can have a better look. From the Cloverly this bone is being offered as a humerus from a Tenontosaurus. I do not believe its one and have included the arm of a Tenontosaurus from my collection to see what one looks like. Its the bone on the left. Could be an ulna but not sure.
  2. This week's red flags This bone is being sold as a neural spine of a reptile or dinosaur. It's actually a pretty complete Chevron and could be dinosaurian. Needs lots of prepping to clean it up. Lots of Dromaeosaur raptor teeth being sold. All are either Abelisaurid indet or juvie Carcharodontosaurid Lots of caudal Vertebrae being sold as Spinosaurus or Carcharodontosaurus, most are Crocodyliforms, unknown or other Dino so post here before you buy Lots of rare phalanx toe bones from Dinosaurs or reptiles being sold this week. Most are Reptlian, Croc or turtle.
  3. A few red flags I would like members to be aware of : This specimen is being listed as a rare Dinosaur bone an ulna. ----Nice piece but its a rib from the reptile Champsosaurus This specinen is being offered as a Carcharodontosaurus foot claw ----Suspect this is from a Spinosaurid since it appears to compare well a known morphology. Would like to see a ventral view to confirm These teeth are being listed as the spinosaurid Sigilmassasaurus from the Kem Kem ----We have no idea how to distinguish teeth from different Spinosaurid's in the Kem Kem. I purchased one tooth from earlier listings to examine it. No surprises met expectation did not see any difference from other teeth other than a slight curvature, no evidence of denticles. Your call. This claw is being listed as an Archarodontosaurus hand claw from Madagascar ----This sauropod is only known from a jaw section and teeth and no postcranial material unless there are unpublished finds. Its the only described Sauropod from that locality but being Jurassic its most likely other sauropods were present. Who knows but nice claw. Reminder to newer collectors, lots of fake dinosaur eggs out there. Post any interest before you buy. Here are a couple For laughs this Dinosaur bone claw tooth being listed. Oh its covered in marine life And finally if you missed this post
  4. Must be a full moon out there Seller is offering this pterosaur skull and claw without any additional information other than saying it had no teeth . Tired emailing him no response as of yet. Looks like 3 wing bones of a Pterosaur from the Kansas chalk. Very nice Edit: seller responded saying it's from Texas and assures me there is an intact skull? A 2" Daspletosaurus offered without any locality. Impossible to distinguish between different tyrannosaurids and without locality who knows what it is. Triceratops vertebra from the Hell Creek being offered. Its not ceratopsian but from an Edmontosaurus which are caudals more rectangular, box shaped. Ceratopsian are oval. A rare Pachycephalosaurus claw being offered. Wow thought yesterday's Tyranno tooth was an awful resto job only to be surpassed by this one. Looks like most of the claw has been restored to something not Pachy. Avoid.... A Giganotosaurus tooth from Argentina is being offered for sale, wow. I know a lot of collectors will want to jump on to this tooth. Caution for a number of reasons. First it was illegal exported, collected in 2014. Second if you need one is that the seller has no locality information and because of that its difficult to determine what Dinosaur its from. Multiple Carcharodontosaurids are present in Argentina. Although the tooth has some appearance of a Carch without additional photos hard to conclusively say its one.
  5. From the Mediterranean Sea. This one is pretty obvious but had to chuckle. Dinosaur tooth with root no a pair of rocks A few Malaysian and Chinese sourced eggs have popped up to support the Jurassic Park movie. Most are fake please use caution. We constantly mention these and they still sell A Drameasauras (raptor) (sellers spelling) from the Glendive Formation of Montana. Most likely Hell Creek Formation. Rib probably from a herbivore, not a rib guy but not a raptor Albertosaurus from the Judith River of Montana A beautiful small Tyrannosaurid tooth from Montana. No Tyrannosaurs have been described from the Judith but since the deposit is similar to Dinosaur Park Fm most likely either Gorgosaurus or Daspletosaurus. Great addition to any collection. Dromaeosaurus teeth from the Kem Kem from domestic seller. A number of these teeth are listed are Abelsaurid indet. or juvie Carch's
  6. Offered these two toe bones from a Spinosaurus. Claw appears to be from a Spinosaurid but identifying the phalanx to one is very problematic. Not a lot of comparative material out there. Regardless that phalanx location does not have a claw next to it.. Offered these two Spinosaurus toe finger bones Both belong to a Spinosaurid but one is a foot claw the other is a hand carpal Offered these three Spinosaurus toe finger bones. Dont believe the claw belongs to a Spinosaurus and like before identifying the two phalanx to a species is very difficult Offered are a Spinosaurus hand bone and claw Very cool pair great addition to any collection. The bone looks like a phalanx not a hand bone indeterminate species but the claw is not like anything I've seen before. No idea whats its from but very nice. Offered are these two unidentified theropod bones and claw. What you have here is an Abelsaurid claw and two unknown bones one of which may not be dinosaurian. What you are buying here is that claw its very nice. There are other other digits, claws offered. If you are interested please post them here and we will give them a look before you buy
  7. At our favorite auction site, new collectors can easily be impressed with a fossil crinoid like this: Even more so as it is a large (470mm X 260mm ), gorgeous fossil for display and highly impressive. So, I am posting this here as a alert to new collectors, who often for being inexperienced, end up believing that a ballot US $ 25 Dollars really can exist... First of all, it's interesting to know that in addition to the seller offers entirely free shipping to the world, it's also important that I explain to you that originally this fossil Crinoid is not white! The problem here is that a strange mass (I highlighted it in pink), is uniting dozens of broken crinoids mounted on a fake matriz plate, as if they were whole crinoids, and to disguise this great puzzle, they simply painted everything in white! And now, problem solved, for hardly a new collector would notice in this small but great detail! Look: Any more problems? Yes! All of these areas that I circled in pink are 100% sculpted by human hands! Look: Now you can compare of Guizhou, what is carved and what is 100% real, which is painted white and the one that has original coloration: I apologize for making your dream evaporate, of placing a Guizhou crinoid next to a Guizhou keichousaurus on your shelf... Do you intend to buy from another seller? No problem! On our favorite auction site there are other vendors who also market Guizhou fossil crinoids! See this one! 100% original coloring, and no sculpture made by human hands here! Look: Beautiful and amazing, is not it? 100% original coloring! But the only problem here is that you are taking to your home a new mosaic puzzle: And under the pretext of "pyritization" and "calcite," you will take entirely free to your home, a strange white mass of glue with something unidentified; But if you also did not like this, no problem, there are more choices of Guizhou crinoids on our favorite auction site: Oooooopppsss! Is gone away this option too! At our favorite auction site you will probably notice that a 100% genuine Guizhou crinoid fossil is nothing perfect, it may not be as gorgeous and complete: But at least now you know the difference between one thing and another thing!
  8. I post this as a reminder to Dinosaur tooth collectors that the Kem Kem Beds is not the only place that you need to be careful when you are looking to buy teeth but offerings from the States can be problematic. New collectors should to be especially mindful that sellers are not always accurate in what they are selling. Best to ask us B4 you buy. Here are a few examples: A beautiful Tyrannosaur tooth is being offered and sold as Albertosaurus from the Judith River Formation of Montana. Unfortunately this species is not described from this locality and currently only known from very late campanian, early maastrichtian deposits of the Horseshoe Canyon Formation in Alberta. You cannot distinguish between species of Tyrannosaurid teeth from campanian deposits. So this tooth is either a Daspletosaurus or Gorgosaurus tooth. Best identified as Tyrannosaurid indet. Aublysodon pre-max tooth is being offered from the Judith River of Montana. Unfortunately this species is no longer considered valid and teeth of this morphology are assigned to other Tyrannosaurids. In this formation, it's either a Daspletosaurus or Gorgosaurus tooth. Nice tooth best identified as Tyrannosaurid indet. An offering of a Nodosaurs tooth, Edmontonia rugosidens from the Hell Creek Formation. Unfortunately this species is not described from the Hell Creek Formation. Currently only Denversaurus schlessmani is the only described Nodosaur from the Hell Creek/ Lance Formations. Again a nice tooth. Be aware that other Nodosaurs may exist in these localities and this tooth is best described as Nodosaurid indet. but until those discoveries are made calling it Denversaurus is acceptable. The Ceratopsian Leptoceratops gracilis is being offered from the Hell Creek Formation. Again this species has not been described from this formation. The teeth are however identical to those L. gracilis and should be identified as: c.f. Leptoceratops gracilis. until we have a named species described. Daspletosaurus tooth being offered from the Judith River Formation. Similar comment as my first one. You cannot distinguish between species of Tyrannosaurid teeth from campanian deposits. Either a Daspletosaurus or Gorgosaurus tooth. Best identified as Tyrannosaurid indet.
  9. The internet is full of improperly identified dinosaur material, not only on auction sites but from very trusted dealers. Remind everyone that the best way to avoid being disappointed is do not assume what is written is accurate, educate yourself in what your interest are or post items here on the forum for feedback. Most of the discrepancies I see are not intentional just lack of knowledge on the part of the seller/dealer or believing what the digger told him. Lets start with the Hell Creek Formation- again Dromaeosaurus is not a species you find in this or the Lance formation, they are all over the web. Dromaeosaurus come from an older deposits, Campanian. Most all the teeth I see sold appear to be Nanotyrannus. The only two Dromaeosaurid teeth in this age are Acheroraptor and Dakotaraptor. A tiny example of what I currently see sold, these look like Nano teeth This individual is selling a Troodon claw. Troodon or now properly called Stenonychosaurus look nothing like this claw and I've provided images of what they should like. This is a reptile claw. The real deal foot claws These vertebra are described from Dinosaur raptors. They are from Crocks or other reptiles, definitely not dinosaur Kem Kem material - I could fill up this site with all the improperly identified material. Please post your interests here before you buy. Reminder we do not know what Rugops or Deltadromeus teeth look like and Rugops is not a species that is described from the Kem Kem deposits its known from Niger. The same is true for Dromaeosaurus that species does not exist in the fauna. Most believe a Dromaeosaurid like dinosaur exist but identifying its teeth is still uncertain. Most of the teeth sold that look like this with the distal edge perpendicular to the base are Abelsaurid indet. not Dromaeosaurid or Rugops etc I saw this tooth being sold, its a huge Carcharodontosaurus tooth 16cm. Please use caution, the seller just talks about slight glue and dirt in some areas but to me there appears to be lots of work done on that crown. Hard to tell whats going on but its more than slight glue and dirt. Just be cautious there is more there than meets the eye and it can get very expensive.
