I was looking at some of my small theropod teeth, but I was not 100% sure what the best ID for these two teeth were. Any input or help would be appreciated. These were sold as Nanotyrannus, but very small chance of dromaeosaurid and Aguja dromaeosaurid respectively, but I think they might be Richardoestesia cf. gilmorei. The cross-section of the Hell Creek tooth I think rules out Dakotaraptor, or at the very least, does not match the known morphology. Edit: Oops, I used the really funky side of the ruler I'm using. I was going to use the millimeter side, but ending up u

Hi everyone! Online I found this tooth for sale, the seller presents it as Afrovenator abakensis tooth from Tiouraren Hill in Niger. In my limited experience I know that it is not always easy to identify which species or genus the found teeth belong to. In this case, from the photos, is it possible to understand if it is really an Afrovenator or maybe another species?

Hi! This compressed, incomplete tooth is 2,9 cm long and has fluting and tiny serrations of the right dimensions for a Suchomimus tooth. Yet it does look quite different than some other Suchomimus teeth I have seen online, so I would love to hear your opinions. The location given is Gadoufaoua, Tenere Desert, Niger, Elrhaz Fm. Thanks!

Any idea what this little tooth could be from? It was found in the Hell Creek formation outside of Faith, South Dakota. It has no serrations and the seller says it may be a juvenile richardoestesia.

Hello everyone. A few weeks ago I received this piece of matrix with remains claimed to be Allosaurus, from the Morrison Formation. I'm not sure if they're even dinosaur, but I bought them anyway to experiment with cleaning it. What is highlighted in green, in the first photo, is where I was cleaning up with a dremel engraver. From a previous post that I saw on the forum, where someone was asking about this same fossil (I apologize if I bought it ahead of time), I read that they suggested just exposing the bones a little more, and preparing the matrix. It's

Is anyone able to actually ID a claw like this? It is 9CM straight. Footclaw or handclaw even? Niger claw as you can see. And I am aware there is not that much information to ID a claw. But this one is pretty much complete.

Hi everyone, this is my first post on here. This specimen was labelled as a 'dinosaur jaw bone' and it was found in the Hell Creek Formation near Glendive, Montana. It is about 27 mm long. It does seem to me it belongs to a reptile of some sort but I haven't been able to find anything on the internet to identify it with any more specificity so I'd really appreciate your expertise in identifying it. Thanks everyone!

Last year when things weren’t so complicated with COVID, we managed to have hunt for dinosaur footprints on the Yorkshire coast. Here’s the beach looking across to Scarborough in the distance. Here are some examples of the prints we came across: Nothing fantastic but all theropods. Heres one in a block that was carry-able: I finally got around to cutting the block to size today although it was freezing outside. So here you go, Theropod Footprint, circa 5 inches long. Middle Jur

Hi all. These are four theropod teeth from the Kem Kem beds that I am not sure about how to assign them. I was hoping you could have a look and let me know what you think. 1. A 3 cm long tooth, I think this one might be Carcharodontosaurid. 2. This one is 1.9 cm long. Distal serrations are slightly less dense than mesial ones. 3. A small one, 1.5 cm. Hard to measure, but mesial denticles appear to have a slightly higher density. 4. A 2 cm ugly one

Did Tyrannosaurus ever colonize the Eastern U.S. during the Late Cretaceous
Joseph Fossil posted a topic in General Fossil Discussion
Tyrannosauridae Dinosaur diversity was unique in the Western and Eastern areas of the North American Continent during the Late Cretaceous era around 95-66 Million Years ago) as a result of a seaway the cut the continent in two (creating the continents of Laramidia (now Western North America) and Appalachia (now Eastern North America)). By the Maastrichtian stage of the Cretaceous 68 Million Years ago, the seaway decreased in size and a land bride formed between Laramidia and Appalachia. https://deeptimemaps.com/western-interior-seaway/ -
Isolated theropod Teeth from the Kem Kem Basin continue to be a mystery. Plan on documenting all the different morphologies I have in my collection to see the variation that exists. Currently we cannot identify any one to a specific species or genus possibly family. I can provide discussion and aid in identification at some point. Just a note, different morphologies do not necessarily mean different species. There are lots of tooth variations in the dentition of a theropod, why its so difficult to nail down an ID even in the best of circumstances. Morph Type 1 A

Spinosaurid Rooted Tooth (Composite root?)
Meatasaurus93 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I recently picked up this "rooted" spinosaurid tooth, and I wanted to get some feedback on it. I have provided both the seller's original pictures and pictures I took of the tooth. My best guess is that there are authentic root elements present, but it's a composite piece. There is a clear seam that runs along the center of the root, indicating that the bottom half of the root was attached to the rest of the tooth. That doesn't always mean that it's a composite, but it's really hard to tell whether the two halves are associated. My inclination is they are not, but I am also not an -
Hi all, Curious to know what family you think this tooth likely came from. Could it be Allosaurid? From Isalo IIIb in the Mahajanga basin of Madagascar CH: About 27.5mm (estimating for tip) CBL (carina-to-carina): 14mm CBW (mesial side to distal side): 8.5mm Mesial Serration Density: 1.9mmm Distal Serration Density: 2.1/mm Thank you!!

Found a partial theropod claw and some other one, not sure if it’s even a claw but I figured I would check. dinosaur park fm

Hey all, Curious to see if you have similar thoughts about this tooth. In terms of that possibility that it's not, in fact, from the Jurassic, I'm not sure I'm seeing the kind of denticle shape/hooking and marginal undulations of Majungasaurus. From Isalo IIIb in the Mahajanga basin of Madagascar CH: About 27.6mm CBL (carina-to-carina): 13.9mm CBW (mesial side to distal side): 7.5mm Mesial Serration Density: 2.2mmm Distal Serration Density: 1.9/mm Thank you!

Hi everyone! I have my eye on what looks like a nice Spinosaur claw from the kem kem, or at least that what the seller claims it is. It does seem to have that round divot under the base of the proximal end that I've seen described as telltale, but you can never be to careful with kem kem claws which might just be the most outright faked fossil on the market so I figured I'd ask for an independent opinion on the potential of funny business (besides what looks to be one or two repaired breaks near the tip). Measurements given are 8.5 x 3 cm. Any insight is appreciated as

Hi everyone! I've had this little Kem Kem tooth for a while now and was hoping for some help IDing it. My gut is telling me premax, maybe from a little Carch which I'm guessing from the thickness though it will probably wind up in the indet. Theropod pile. No base to provide CBL and CBW so I took measurements at the best cross section that was left. There is a mesial carina though it is very subtle and only extends halfway down the specimen's length. Any insight is appreciated as always!

Fragment takes up most of the sediment which is 1.5cm please not the serrations in the photos. All photos are the same with different lighting. @Troodon @jpc Is this actually a tooth fragment or are the serrations fooling me?

Big news today impacting the ongoing controversy if large theropods were lipped. Abstract: Large theropod dinosaurs are often reconstructed with their marginal dentition exposed because of the enormous size of their teeth and their phylogenetic association to crocodylians. We tested this hypothesis using a multiproxy approach. https://www.science.org/doi/10.1126/science.abo7877 Mark Witton blog http://markwitton-com.blogspot.com/2023/03/new-paper-fresh-evidence-and-novel.html

The other day, I was indebted to you for the spinosaurus vertebral fossil. I have a question. Does the dinosaur's air sac match the marked part in the picture? The fossil in the photo is the sacrum of spinosauridae. Thank you . (⌒‐⌒)

Is there a way to distinguish the vertebral of theropods and ornithopods? They the same to the untrained eye.
