Hello, a quick question. I bought this tooth as Daspletosaurus tooth 2 1/8. it was found in the Judith river formation (exactly?) is it conceivable that it is also a Gorgosaurus tooth? Or is it even possible to determine exactly? I would be very happy about your opinion. Best wishes.

Sorry this vert is super messy but it’s got some super tough stone on it that I’m not sure I can remove, it’s in rough shape. it’s got a similar shape to some tyrannosaurid verts I’ve seen so I’m curious if it’s that or something else. Would have left it on the ground if I didn’t suspect tyrannosaurid but had to check. Thanks!

Red Flag on Kem Kem Dinosaur Material
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good examples of reconstructed vertebrae can be seen on the Web at hefty prices. In this example the seller properly identifies it just has a theropod and says the repair is "using the filler method " and it's an investment grade fossil. It's impossible to tell what has been done to this vertebra but what is evident is that the processess have been added and covered using the " filler method.. We do not know if the processes belong to the centrum, my guess probably not, or if the front and back are from the same vertebra. All the sand fill tells you how much repair has been done to the specimen. Here the seller is offering an associated pair of tail vertebrae from a Spinosaurus. In my opinion they don't look like theropod vertebra more like croc but I really don't know. Again the excessive sand matrix on the sides is a red flag for problems. Another Spinosaur vertebra being offered. Think I've seen this one before. The processes have been added and we do not know where from in fact the short ones don't even look like processes but peices if bone. The centrum may be Spinosaurs but identifying vertebrae in the Kem Kem without known processes is very problematic. . This is what caudal "tail" vertebrae looks like from a Spinosaurid..thumb.jpg.98654cc3d5155d112e5f1dc6204eeb07.jpg)

I can assure you it is fossilized bone it just doesn’t look like it in the pictures because of how dirty parts of it are and the bad camera quality. It’s about 3 pounds 5.5 inches long and 4 inches wide. horseshoe canyon AB

Identified by a palaeontologist as a hadrosaur vertebra and I would like to get some clarification. It’s 3-4 inches long and 2-2.5 inches wide. Found in Horseshoe Canyon Alberta.

Struggling to figure out what this might be. Apologies for hands in the photo again but this thing definitely won’t stand by itself. Might just be an unidentifiable chunkosaurus but the weird texture at the top made me curious if it’s skull material of some kind

Hello, Heres another chunk of interesting-looking bone for which curiosity has finally gotten the best of me. This is a piece I picked up in 2021 on my summer dig at the Hell Creek Formation in Montana. I feel there’s a chance this piece might be identifiable. This piece of bone is bowl-shaped with a strange web-like texturing on the convex side. The edge of the bone which is not broken is rounded and almost flower petal like. There is a set of T-shaped rounded ridges on the concave side. Not the best quality bone either, with significant siderite encrustation being present. I have a few wild ideas about what this might be but want to hear some unbiased opinions. Any ideas and help is much appreciated.

This is for sale on a local auction site.... I get a bit of an off feeling about it and feel like it's some sort of fake (it looks plastic) but it's definitely worth asking the question from those that know about dinosaur eggs. The auction title says it is a million year old Therizinosaur egg fossil - yep, seriously. There is zero provenance, so how the seller knows what family of dinosaurs it belongs to surprises me. Based on the title, the seller knows nothing about it either. Seller admits it was a garage sale find, in the listing there is a page worth of info about dinosaurs but nothing specific about this "egg".

Hi all, I'm relatively new to the fossil world. I've purchased a small number of dino & meg teeth so far from a few (3) dealers but looking for an expanded list of reputable dealers of this sort of material as I build my collection, especially dino (teeth, claws, mostly.) I know public discussion of dealers here is a bit of a no no so hopefully some of you can PM me with any recommendations? Or alternatively, any to be avoided if you feel like sharing this privately also. Mostly interested in better quality specimens, so not ones that have undergone significant repairs/restoration, or which are in poor condition etc. Cheers

There are a lot of experienced dinosaur collectors out there but for the newbie I thought a topic on the anatomy of bones and teeth would be beneficial, in plain english. Avoids reading pdf's that are difficult to get through the technical terms. Orientation Skeleton The specific sketal structure of a dinosaur varies between theropod and herbivore but the major elements are typical. Skulls of dinosaurs are not comprised of a single bone but many elements See the osteology of a Trex skull on page 2 The holes in the skull are identified as follows Theropod Teeth Theropod teeth are widely collected let's look at their anatomy and nomenclature Tooth Orientation Apical- The direction from the cervix to the apex (Fig. 1C, E). Basal- The direction from the apex to the cervix (Fig. 1C, E). Mesial- The direction towards the jaw midline, center (Fig. 1C). Mesial can refer also to the surface facing the jaw midline, center. Distal- This term is used slightly differently for teeth versus denticles. For teeth, distal refers to the direction away from the jaw center and towards the posterior end of the jaw (Fig. 1C). For denticles, distal refers to the direction away from the crown, from the denticle base to the denticle apex (Fig. 1E). Proximal- From the denticle apex to the base, proximal refers to the direction towards the crown ( Fig. 1E). Labial- The surface or direction pointing from the skull outwards, thus towards the lips or cheeks ( Fig. 1D). Lingual- The surface and direction towards the skull midline, thus facing the tongue ( Fig. 1D). Tooth Situation and Position Isolated Tooth- Tooth shed or non-articulated with the toothbearing bone. This is what collectors typically purchase. Shed Tooth- Tooth lost while alive,, either falling out due to the eruption of the replacement tooth or when processing food (e.g., biting, impaling, shearing, chewing), and therefore only preserving the crown and the basal-most part of the root. In Situ Tooth-Tooth within the alveolus of the tooth-bearing bone. Erupted Tooth- Tooth that grew outside the tooth-bearing bone, thus fully visible in the mouth. Unerupted Tooth- Tooth within the alveolus and still inside the jaw, and therefore not visible or only partially visible in the mouth. Premaxillary Tooth - Tooth in front of the upper jaw, typically four would exist in a theropod Maxillary Tooth - Tooth in the upper jaw that follow the Premaxillary teeth. Dentary Tooth- Tooth in the lower jaw Tooth Anatomy Crown (co) Portion of the tooth covered with enamel, typically situated above the gum and protruding into the mouth Root (ro) Portion of the tooth beneath the gum and embedded in an alveolus or an open alveolar groove

Hey y’all, need some help again, got at least one claw here but not sure about the second one. The smaller one is some sort of theropod claw but not sure from what, and the top one I’m not entirely sure is a claw at all but figured I’d get it checked out. Both are dinosaur park fm. Any help is appreciated.

Connecticut Dinosaur Print Specimen?
Maniraptora posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all! I’m considering buying this specimen which is identified by the seller as dinosaur prints from Connecticut, but first I wanted to make sure it’s what it claims to be, and not an instance of pareidolia or similar. I also was curious whether anyone here could offer some additional info on the prints—any guesses on age, formation, more specific locality, ichnogenus, etc.? Thanks in advance. I’m very excited to buy this if none of you have any bad news to offer!

From the album: My collection in progress
Spinosaurus aegyptiacus Stromer 1915 Location: Kem Kem Beds, Morocco Age: 95 Mya (Cenomanian, Upper Cretaceous) Measurements: 7x2 cm Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Reptilia Subclass: Diapsida Superorder: Dinosauria Order: Saurischia Suborder: Theropoda Family: Spinosauridae -
I found something from our favorite auction site that looks very interesting, however I have my doubts if it is legitimate or allosaurus, and would like to hear someone else's input. Seller describes the item as a fused humerus and radius, but I am guessing they mean ulna and radius, of an Allosaurus, found in the morrison formation. Do anyone have information regarding whether these bones even fuse in theropods, or whether they even resemble the ulna/radius bones of Allosaurus? Thanks

Is this a real dinosaur egg?
Kyleontheweb posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I apologize in advance as I'm sure questions like this come up a lot. I'm thinking about purchasing this dinosaur egg which I believe is from a fairly reputable seller. I've always wanted a real dinosaur egg for my collection, but I just wanted to get some opinions on whether you think this one is real or a fake? Thank you very much for any assistance!

Big spinosaurus tooth with Pathology and serrations?
JorisVV posted a topic in General Fossil Discussion
Here by my new Spinosaurus Aegypticus tooth from Taouz, Morocco. It is 4 1/2 inches. The colors are less common than your regular Moroccon Spinosaurus teeth. It has 0 restoration done to the tooth, and the quality is very high. Which I find special about this one. Noticed some slight patho and serrations on this tooth too? Could someone explain the patho perhaps.

If you still have to watch or want to watch 'Jurrasic World Dominon' this topic is not for you , click away! spoilers ahead So I went to the movies yesterday and saw the new movie as the first day you could watch it. There were a few things that caught my eye and don't seem right. 1. They mentioned a few times that Giganotosaurus from Argentinië was the biggest meat eating Dinosaur ever lived the earth. This was Spinosaurus ? Very weird that they would say this over and over in the movie, while Spino was the biggest, the Spinosaurus was not even featured. 2. They showed the Mongolian Deinocherius, with its impressive massive arms and claws. They showed it as a vicious killing machine, it killed a deer in the movie lol and hunted one of the main cast. While it was actually most likely a sauropod (it did not have any teeth and a flat horse like beek and skull, it used it claws to fetch fruits most likely or to protect itself. Just found it a bit wierd that it was shown like an predator like Trex. 3. I could see a few times the movement of the dinosaurs was a little chunky , cgi was not that impressive sometimes. What also is weird because Spielberg's first take in 1993, is still today awesome to watch. So bottomline, it was no were near as good as the first one, what was expected, its impossible to beat it. Still enjoyed it. What are your thoughts on it?

First Dinosaur Belly Button Discovered in Fossil From China

First Dinosaur Belly Button Discovered in Fossil From China Link: First Dinosaur Belly Button Discovered in Fossil From China | Smart News Science| Smithsonian Magazine -
Hello, I recently bought this tiny bone fragment, a supposed piece of Tyrannosaurus rex vertebral process, from the Hell Creek Formation of Harding County, South Dakota of USA. I know nothing about ID'ing dino bones or bones in general. The seller's rationale for the ID was that the porous honeycomb structure is diagnostic of large theropods, with the only one in this formation being T. rex. Does the ID seem correct? Is this T. rex proper or is that impossible to determine? The piece is 3 cm long. I've propped it up to better visualize the large pores inside the fragment. Also, I'm wondering what the black, chocolate-looking substance filling many of the pores is. Is that just what the matrix looks like? Thanks,

Hello, Thoughts on this? Associated and connected sacrum verts from Laos - Gres superieurs. 5 inch long. Seller id'd it as a ornithomimid, but was told it could be other theropod. That formation just has a handful of species described. No ornithomimids. But is anyone able to take a look and shed some light. Ornithomimid, raptor, even juvenile ichthyovenator etc. If ornithomimid, it would be an entirely new species? With none described from there or the equivalent Khok Kruat Formation?

We found a few dinosaur eggs located in Utah. Not quite sure on exactly what they were laid by or even if they are fossilized eggs.

Hi all, I have just had a read through all the information for new members when submitting new fossils for identification. I will do my best to try and cover all the items listed and hope it helps anyone to identify my 2 fossils. The two pictures are indeed high-res images so that’s a good start. However, first off, I purchased these two fossils from a large estate sale. There were a number of other fossils available but these two were the most majestic which caught my eye as they looked quite bizarre and unusual to me. They are mounted on perspex. Sadly, since they were from an estate sale, there was zero paperwork available and no one at the auction house could assist with identification. I have done a bit of research (thanks Google) but couldn’t pinpoint any dino fossils that even looked similar to these ones. I did suspect Mesosaurs but the head just doesn’t look quite right. I also do not know if both fossils are of the same species. I am located in Australia, however that in no ways implies these fossils are Australian. The estate sale included items from the US, UK, Africa, Peru, Europe and everywhere else. Whoever the estate belonged to had an impressive collection. Here are some measurement for the 2 fossils. Photo 1 (with the head and beak pointing upwards): Head to Tail Length: 650mm Width at widest part of the body: 60mm Head and beak length: 50mm Tail Only length: 320mm Body Only Length: 200mm Photo 2: Head to Tail Length: 520mm Width at widest part of the body: 50mm Head and beak length: 60mm Tail Only length: 250mm Body Only Length: 240mm In any case, any help with IDing who these 2 little fellas are would be very much appreciated. Anyone else think it’s a Mesosaurs?
