Is this a real Hadrosaur toe fossil?
DinoNewbie posted a topic in Is It Real? How to Recognize Fossil Fabrications
I am thinking about buying a Hadrosaur center toe fossil. Before I buy the fossil I am wondering if they are real or fake and how I can tell.

Hi, I recently bought these Dino eggs.I would appreciate any opinions on these as far as being real or fake?Quality etc.Thanks
-
I'm wondering what this is. My best (non-expert) guess is that it is a toe bone of some sort. It's about a couple inches (appx. 5cm) in length & equally wide. It resembles some smaller Hadrosaur phalanges I've come across, but that is just a guess. To the best of my knowledge, it hails from Hell Creek. Any thoughts? Thanks in advance!

Unfortunaterly, there's not much information--the seller doesn't usually deal with dinosaur fossils and has had it instorage for over a decade, so the only info available is that it's a Hadrosaur egg, from China and cretaceous with shell loss to one side. No more specific as to location/formation. Length = 17.5 cm Weight = 4.3 kg So, what do people think about it? Now, I was wondering, could the base be hiding some damage/a hole? The base looks a bit off to me, like it's been added---is it a common bit of fakery to make a partial egg look complete by applying a base to them and could that be the case here? Thanks for any help and opinions.

Two eggs--if someone can take a look and let me know what you think, that would be great. They are Hadrosaur eggs from China. From the Nanxiong Formation in Guangdong Province. Seller says no repairs or restoration. And adds that the first egg is more complete than the 2nd. Egg 1: 10cm x 6CM Egg 2: 11cm x 7 cm Now, does the slight difference in size mean they could be from different species, or can dino eggs from same species sometimes be slightly smaller? Or could the size difference just be due to fossilisation--one getting a bit more squashed and elongated than the other? Now, with these--I assume the brown stuff is sand and matrix covering the shell---that wouldn't be a cause for concern and be hiding something shady?

Another hadrosaur egg thread - fake?
Bethshine83 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi My son has recently been given this ‘fossil’ by a relative. They bought it about 20 years or so ago from an antique shop in Hong Kong. They were sold it as a hadrosaur egg but we have no idea really if it is or not. I’m inclined to think not simply because I’m always suspicious

A new study got published on some new hadrosaur material from Spain. https://www.sciencedirect.com/science/article/abs/pii/S0195667120303645?via%3Dihub Abstract It's paywalled sadly.

Hey! These are just a few of the bones I found recently which were all found near each other in horseshoe canyon AB. I found what I believe to be albertosaurus teeth and a piece of a hadrosaur jaw as well with them which makes me assume they are from one of those two species. However, I need help identifying which species each one might be from and what part of the dinosaur they are. If you need measurements I'm happy to post pics next to a ruler!
-
Hey! Both of these teeth were found in the horseshoe canyon in the same place. I was thinking Albertosaurus but I don't know(They are serrated if you couldn't tell from the photos). Any ideas? (sorry for the low quality images)

In this image, you can see the enamel, dentine, and pulp cavity. The surface is worn flat and smooth. Nice blue color in there. -
Hi again everyone Here is Bone likely from Hadrosaur (as far as seller told me) from Lance creek formation . It look like to be a partial section of Metatarsal bone ? what do you think guy??? Thank you in advance !

I found these toe bones yesterday in the Judith River Formation near the Canadian border. I have found several bones like these but not completely sure of the identification to give them. They appear hadrosaur or triceratops like based on a google search of other similar bones. Let me know if you can identify them.

I found a bunch of these teeth on the Judith River Formation yesterday and not sure of the identification. Based on google searches they appear to be (from left to right) triceratops, ankylosaurus, and Hadrosaur. The one on the left is about 3/4" as a reference. Any direction would be greatly appreciated.

These pieces were both found in the horseshoe canyon cretaceous formation in Alberta. There were multiple hadrosaur teeth and bones nearby, so that could be a starting point. Could anybody help me with an ID?

Hi everyone, Wondering whether or not you think this looks like a Hadro skin impression. Basic Info: South Dakota Hell Creek FM Cretaceous 65 MYO

Hello, So, I see these teeth sold a few places and will probably get one because I don't have any hadrosaur teeth from Aguja yet. But, is the id of Kritosaurus correct, or is it a term labelled to teeth the same way deltadromeus is often thrown onto Moroccan teeth. I see the two described hadrosaurs from there are Kritosaurus and Aquilarhinus, but is there a chance that other undetermined remains could be from there too, so these teeth would be better labelled as hadrosaurid? Or are they likely to be Kritosaurus or Aquilarhinus? Thanks

tyrannosaurus, hadrosaur and other Dino Teeth Repair and Restoration?
CEP posted a topic in Fossil ID
A couple of the bigger Tyrannosaurus teeth I found this summer in Montana Judith River formation. I found this 3" tyrannosaurus tooth in about 400 pieces and was able to piece about 80% of it together over about 3 weeks and 30 hours, the other one is almost as big but was only in about 30 pieces and is still a nice brown color. I am no professional and did not want to pay thousands to have someone do it for me. I would like to get it filled in and solid, is there some putty or epoxy used to fill it in and hold it all together? Also had some other smaller Hadrosaur teeth I believe and maybe a croc tooth but not certain. can anyone ID those?
-
I realize this is a long shot for a Hadrosaur tooth but what do you all make of this? The composition keeps befuddling me, its so smooth but not like slag and not concretion. Any ideas?

Just wanted to post some of my favourites from the last few months of collecting. Winter is only a few short months away so I’m heading to the field whenever I can. We’ve got some tyrannosaurid (gorgosaurus or daspletosaurus) toe bones as of this morning! Very excited about that. Bunch of verts including a big one, I know most of the verts aren’t from the same animal but I like to set them up like a tail for visitors The ornithomimid claw, a few tyrannosaurid teeth, croc scute & skull section (I believe that vert belongs to a croc as well, the one before the string) little theropod limb bone and the longer one under the claw I believe is ornithomimid as well as it was close to the claw. Maybe a radius or ulna? Also putting some photos of my friend & I out in the area and the landscape itself. Enjoy!

Hello! We were at Big Brook today and my son found this. Not sure what it is (if anything) and I cannot find any thing similar on the Big Brook websites. We also found some teeth and what might be a hadrosaur tooth fragment (second image). Can anyone confirm the hadrosaur tooth?

I finally finished a shadowbox display for some of my Edmontosaurus fossils. The top 2 are a proximal and distal sections of dorsal ribs. Both found a few inches apart, but are probably not the same actual rib. Bottom right is a small rib head section my son found 10 years ago. Its either a juvenile rib head or an adult cervical rib. Bottom left is an ossified tail tendon and the only complete one I've found (or even seen found). You typically only find 1" - 2" long bits and never the vertebral connection. I find it rather funny how much time was spent cleaning, repairing and prepping these to remove all the matrix, only to carefully craft a display that makes them look like they are still embedded in matrix. The "sand" background the bones are mounted in is actually the matrix these fossil came from. I collected a small amount from the quarry, then screened it before gluing it to the mount surface. The final thing I have left to do is create an informational data plaque for it.

I recently got this rather nice Edmontosaurus annectens braincase from the Lance formation. But what's interesting, it has this large hole in the top of the skull. The seller has told me that the hole is not the result of any collecting or prep damage. The seller found the piece themselves and apparently it was found upside down in the field. I've bought from this seller before and they always have high quality fossils so I'm inclined to believe the seller when they say that this hole is old damage. So then my first thought would then be, could this be a big tooth mark? Although I don't want to jump to conclusions. It's a large gash on the top of the skull. On the top there are a few pieces of bone that kinda seem like they were pushed in and on the side there are some bone fragments that seem to be kinda push out. Something pushed in from the top and then ripped out to the side maybe? I have some T.rex replica teeth and one seems to fit fairly decently. So I'm wondering, how plausible is it that this is a T. rex bite mark? We know T.rex ate Edmontosaurus of course, and we know it can crush bone. Opinions? Braincase overview. Hole closeups.
