Just acquired this “tooth” from an antique store… showed it to a rock hound here in Utah.. he said it looked like a Sauropod juvenile’s tooth.. can you comment and help?

My first post on the forum was to see if anybody could show me an adult specimen of “Nanotyrannus.” I was more forceful in that approach because, from what I’ve seen on Twitter, “Nano” fans like to argue with paleontologists on the validity of the genus, even though these scientists have been studying dinosaurs for years and have degrees and Ph.Ds in different scientific fields. The evidence points them in a different conclusion compared to the public, and the fact that they are being so heavily resisted against with regards to this topic is baffling. I decided to play the “Nano” fans at their

The photos below show two juvenile/hatchling ichthyosaurus species from Yunnan, China. They are from two different localities but are close by. As they look quite different, are they different species? And any idea what species they are?

Back in February, my partner found a small tooth that I initially thought to be Gomph. I made him an offer he couldn't refuse. I sent some photos to Richard Hulbert and (surprisingly to me) Richard identified it as a Rhino upper cheek tooth. I did not argue, and once I spotted the Hunter_Schreger Bands in the 1st photos, thought the ID to be correct , although I have never seen an upper Rhino tooth that had this wear pattern. This is what upper T. proterum Rhino teeth look like in Florida, Does anyone recognize my tooth in this photo below? Fast forward to

Hi, I am new to this forum. I have had an interest in dinosaurs since I was a little kid, but this has "matured" in recent years. Recently, I got a tooth as a present. It was bought as a Carcharodontosaurus tooth, about 19 mm long (0.75"), at a large exhibition/museum in Kalmar, Sweden. But since the creator of the exhibition managed to lable a (flattened) Mosasaur scull as a Carch as well, I am not too confident in the identification. The tooth is small, but pretty. Did it belong to a juvenile Carcharodontosaurus, a Deltadromeus, or something else? I would be grateful for any help on thi

Juvenile Psittacosaurus - real or fake?
Tressmeister posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! I would like to know your opinions on the following Psittacosaurus mongoliensis specimen. Found in Liaoning, China. Size about 20cm long and ~1kg heavy. I see there's quite a lot of glue/consolidant here. I know some are carved and many are composites but I would like to know your opinions. Is this real or fake? Your input is highly appreciated. Cheers! -
Very young fish (27mm) in which the scales have not yet ossified. Juvenile specimens of Diplomystus dentatus can easily be mistaken for juvenile specimens of Notogoneus osculus. But juvenile Notagoneus can be easily recognized by the larger skull and the position of the anal fin, which is set far back. For comparison a specimen of a juvenile Diplomystus dentatus preserved on the same slab: Taxonomy from Fossilworks.org. Revised generic diagnosis from Grande and Grande 2008, p. 10. "†Notogoneus differs from all other genera in the family Gonorynchidae by the fol

Hi there everyone! I thought I would ask for some help in properly identifying this specimen that I recently acquired. This specimen is said to be a baby/juvenile M. Columbi tooth found in North Florida. The specimen is very obviously worn and has pink patches due to algae buildup. I’ve included several photos below: Front, Right, Left, Bottom, Bottom, Top (Chewing surface), Top (Chewing surface). I’m fairly certain this is a mammoth tooth but I’d greatly appreciate a positive ID since I can’t find much information about specimens like this online. My

Associated Vertebrae?
Nanotyrannus35 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I'd came across an sale listed as an associated pair of juvenile Hadrosaur Dorsal vertebrae - from the Judith River Formation. I had been wondering, are they really associated, and how can you tell if fossils are associated? Here are the pictures from the seller. -
Is this a Two Medicine juvenile tyrannosaurid or Richardoestesia tooth?
-Andy- posted a topic in Fossil ID
Hello, this tooth has baffled me for years. I can't tell if it is a juvenile tyrannosaurid dentary tooth or a cf. Richardoestesia gilmorei tooth Its locality info is Montana, Two Medicine Formation The tooth has a serration density of 19/5mm on the distal mid-line. Unfortunately the mesial carina is worn down so that crucial data is missing The CH is 11.5 mm, CBW is 7 mm and CBL is 4.5 mm As far as I am aware, juvenile tyrannosaurid (with the exception of T. rex) have slender teeth while as this tooth is somewhat robust. Meanwhile, Richardoestesi- 2 replies

Ok, this piece is why I'm here. I would like to have it's identification verified and need to know if it could be a fake. It was given to me, not by the person who found it but by a mutual friend who didn't know to ask any questions about the piece when it was given to him. The original collector has since passed so there's no going back for Q&A. I do believe it was found somewhere in western Nebraska, southwest South Dakota, or eastern Wyoming as this area is where the original collector did most of his hunting. However, I do not know this for certain as it concerns this piece specificall

Not entirely sure what I have, I'd love to think it's a baby trex, but I can't be certain. Y'all take a look and tell what you think. I can always snap more pics, so let me know what everyone thinks, Thank You.

Juvenile Tyrannosaurus rex tooth from Hell Creek?
TeethCollector posted a topic in Is It Real? How to Recognize Fossil Fabrications
I saw a Juvenile Tyrannosaurus rex tooth (or Nanotyrannus) with really good price.. Seller told that this is from Hell Creek formation, Garfield County, Montana. I can't find any oddity or fabrication... but I want to hear everyone's opinion since the price is too good to be true. -
Hello together, I am not entirely sure if the fossil ID section is the right place for this, but I am hoping for information on a fossil specimen, its not one I hold in hands, but a ct scan, and I think I may not post pictures because they are copyrighted. While looking for new inspirations for my model building I took a close look at this wonderful ct scan of a Simosuchus clarki skull. A pugnosed crocodile, how sweet is that? I wonder two things: -how is that bilateral bone called that in many crocodiles protrudes downwards from the skullbase reaching between the ma

Good morning another good day in The Brook. My best find which I was able to identify was an iPhone 11 which I reunited with it’s owner. Photos below are of a humerus. Most of what I find is deer but this one is substantially smaller. Is it a juvenile deer or something else? As always, thank you for sharing your expertise

Hi all! I just obtained an 8 mm juvenile T. rex tooth and have compared it to my 13 mm juvenile nanotyrannus tooth. Even though they are located in different positions in the jaw, there is a remarkable difference in the two teeth. I just don’t understand how these cannot be two different species?! The debate goes on...

Juvenile Elasmosaur Skull
Norki posted a topic in Partners in Paleontology - Member Contributions to Science
Last summer, on the last day of a long weekend of backcountry fossil hunting around Lake Diefenbaker, Saskatchewan, my friend and I decided to stop our canoe at a beach where on a previous morning I had found a large baculites cuneatus specimen. This beach was an outcropping of a unit of the Bearpaw formation known as the Demaine sand, and dated roughly to the late Campanian. The locality was chock full of golfball to softball-sized nodules, each with a delicate, coalified fossil inside, ranging from crustacean parts, chips of driftwood, to loose vertebrae. It wasn't long before I was looking- 22 replies

Hello. Every once in a while I see these "juvenile Diplomystus" listed on our favorite auction site. The fins seem to match Diplomystus, but it would be great if someone with more GR knowledge than me could shed some light. The little guy is 1" long, tiny

Hi the debate about Nanotyrannus got me thinking is Nanotyrannus found in Alberta Canada in the Scollard or Frenchmen Formations. If not then it could be valid since T-Rex is found there and if it’s a juvenile Rex then there should be a least some evidence for It there, since T-rex’s are found there. And if so this could provide Nanotyrannus’s range.

Hello all! I have acquired a very nice juvenile tyrannosaurid tooth from the Judith River Formation. I am fully aware that teeth from there are very difficult to be assigned a specie, but I was wondering if it could be narrowed down a little. Last time @Troodon was able to give me awesome info and help. The tooth is a premax tooth and is 1,7cm in length. I have a serration count for both distal and mesial sides: hard to tell for sure but it looks like 3/mm for the distal 4/mm for the mesial Thank you

Hi guys, I have recently acquired this Mosasauroid partial jaw. Seller claimed it is a juvenile Mosasaur. He acknowledged that some of the teeth may have been reattached. But he didnt know which, he got it from his supplier like this. And upon further questioning, he also admited that he is not absolutely sure about the genus. He speculated juvenile Mosasaur due to its size, but i dont think a smaller genus of Mosasaur, like Halisaurus, Tethysaurus or Platecarpus, is out of the picture. Please help me identify the genus of this Mosasuroid and the location

On my birthday I got a juvenile gorgosaur tooth didn’t look special other then the colour but then I started to check it out and study it and instead of serrations there were small holes so I came up with a theory how juvenile tyrannosaurs didn’t have serrations until they got older yet I still need more proof to back up my theory but I found it interesting it was collected on a ranch in the Judith River formation not to far from the Canadian border it is 75 million years old here are some photos of it.
