Here's a 45 cm / 17.7 inch long bone from the Kem Kem of Morocco. I don't know what animal this belonged to. Maybe a theropod or crocodilian?
-
Found this little guy today. Wondering who it belongs to. Looks almost identical to one of my tyrannosaurid toe bones (pic for comparison) but the tyrannosaurid one is much bigger. e; sorry forgot, Dinosaur park fm

I decided to expand my obsession with sharks towards an obsession with theropods. I received my first piece today, a Spinosaur from Morocco, even making a display resembling the rolling deserts of the Sahara for it. This thread will be updated when any further theropod teeth arrive

Good evening everyone! Few days ago I found this bone fraction on the southern shore of Dusia lake, Lazdijai district, South Lithuania. The maximum thickness is 6 mm, the thick layers and bone canals are also well visible. There were three times when I noticed very similar bone pieces in fluvial sandstone boulders of Siauliai district (Northern Lithuania) too. By me some limb bone cross sections of theropod dinosaurs look similar but I need professional ID of this bone taxonomy- I am sure it belongs to tetrapod, probably reptile or less likely mammal. Any opinion will be appreciated! Best Regards Domas

Chenanisaurus Barbaricus Tooth? Or Carch?
Kurufossils posted a topic in Is It Real? How to Recognize Fossil Fabrications
Came across this tooth labeled as an abelisaurus belonging to chinanisaurus barbaricus from the Maastrichtian supposedly found in the phosphate mines of the Ouled Abdoun basin. Looks pretty thick to be abelisaurus and comparable to an extent to some carcharodontosaurus teeth. Is there a way tell the difference or will there need to be more specifics involved.

I found this half of a phalanx bone in the upper Dinosaur Park Formation. I’m wondering whether it belongs to a turtle or a small theropod. Would any of you guys know what it is? Thanks!

I found this rock in some landscaping rocks in Arapahoe country Colorado. I know it will be tough. I hope the photos will be enough to get a confirmation that it’s a real footprint and maybe get an I.D There is also a lot of plant material across the whole thing which I hope is proof that it’s fossilized top view with light from the front to outline the detail of the footprint top view back view left view front view right view bottom view Close up of the largest plant piece. I don’t know If the 6 side photos matter with a rock like this but I want to be as accurate as possible.

So I bought these tooth-fragments at a fossil show back in December in Hamburg, Germany. The seller had a lot of different fossils, including a huge ilium bone of a sauropod from the Kem Kem beds, as well as a tibia from a large indet. theropod (Which according to the seller was Spinosaurus). Other than that, he sold large tooth fragments from the Montana, Hell Creek formation, probably Rex, but no complete Rex teeth. Some dromaeosaurid teeth from the Hell Creek formation, and various herbivorous dinosaur teeth from the same formation too. A lot of ichthyosaur bones from Dotternhausen, Germany. Some fossil amphibian skulls, can't remember where from or what species exact, some of them were still in a matrix, the bones were almost red and looked a bit similar to that of Eryops. He also sold small plastic containers of tooth fragments from China/Mongolia, labelled "Tarbosaurus". I bought one of these containers. The seller told me they were collected near the border between China and Mongolia. I was never truly sure if they were 100% Tarbosaurus, could literally be any other theropod. And considering there was no specific location or formation, it's really hard to tell what I've actually bought. I've had some people write to me, wanting to buy the fragments, and have each and every time told them, that I really can't know for sure what these fragments belonged to. Just recently I bumped into this tooth (as seen below here) online for sale: It is described as a Carcharodontosaurus indet. tooth from the Kem Kem beds of Morocco. And the coloration looked oddly similar to one of the fragments I bought at the fossil show. Now, before you say anything, I know that coloration varies a lot within every location, and some locations may yield fossils that look identical in coloration to other locations' fossils, but I just thought the reddish tone underneath the enamel seemed very familiar in regards to especially 1 of the fragments, which is a partial tooth, and also the most complete one from the little container I bought. (See the partial tooth below): The tooth on the above pictures has the following serration counts: Mesial carinae: ~18 serrations per cm, roughly 2 per mm. Distal carinae: ~20 serrations per cm, roughly 2 per mm. It measures: 2,5 cm at its longest dimension. 1,4 cm wide. About 0,9 cm thick at the thickest point. After seeing the picture of the Carcharodontosaurus indet. tooth for sale, I thought maybe this could be a Kem Kem tooth too. Anyone who's got a guess or a hunch?

Hello. I am considering trading for a few late Cretaceous-era theropod teeth from the American West (I think Wyoming/Montana) and would like some help confirming what they are. They are in ok condition, but I don't have any dinosaur teeth in my collection so I am very excited to bring these in. I'm not sure what formation they are from. I was hoping to narrow these down to a species, or at least get a second opinion. First one is a tooth that I was told is a tyrannosaur ind. Thoughts? I have been reading a lot of what @Troodon has posted so I am tagging him since he seems to be the resident expert. I will post pictures of the others as soon as my fellow trader sends me them. Thank you!

Hi again, I saw this tooth online and was wondering what you guys could make of it. The seller calls it a ‘Nuthetes’ tooth but from my knowledge Nuthetes has not been found in France. Something odd to me is the preservation, it just looks off for France. The seller has provided only one photo but a decent amount of information. Let me know what you think. Chevres-Richemont Quarry Chevres-de-Cognac, Charente, SW France France Extremely rare 15mm theropod. Dinosaur, Theropod

Found this theropod tooth in my Aguja formation matrix from west Texas. It's narrower and has more serrations than the usual theropod teeth I find there. Any ideas as to what kind? Hash marks are 1mm. Thanks for any help.

I saw this for sale as a theropod finger bone from Hell Creek, Garfield County. I googled theropod finger bones and nothing seems to match at all. To me, It looks more like a hadrosaur finger bone. Any thoughts? Thanks

Looks like we have a new dinosaur from the UK: Vectaerovenator inopinainopinatus The University of Southampton has confirmed that vertebrae discovered at Shanklin on the Isle of Wight in 2019 belong to a new species of Cretaceous era theropod. Believed to be up to 4m long, the dinosaur had notably hollow bones. "Chris Barker, a PhD student at the university who led the study, said: “We were struck by just how hollow this animal was — it’s riddled with air spaces. Parts of its skeleton must have been rather delicate"." News article: https://www.google.com/amp/s/www.bbc.com/news/amp/uk-england-hampshire-53738762 Full publication expected in 'Papers in Palaeontology' soon.

Seems the questions raised around that exciting news of an avian dinosaur preserved in Burmese amber were right after all. The original paper has been retracted by its authors, after the discovery of another fossil closely resembling the previously discovered skull portion of Oculudentavis was classified as a species of lizard, rather than an avian dinosaur. Disappointing for dinosaur fans, but it doesn't change the fact that any Late Cretaceous vertebrate preserved in this way is still an exceptional find.

It's been a little while since I've popped in to the fossil world properly, but I finally came across another unusual little theropod tooth from the riddle that is the Kem Kem, and just had to pick it up. The overall size and a bit of chunkiness going on here discounts the theorised dromaeosaurid(s) from the locality, and the recurved distal edge doesn't scream abelisaurid. Nothing about it particularly says carcharodontosaurid either, and I can't find a clean match with the morphologies of @Troodon's id guide, though 'morph type 3' is possibly the closest.....so anyone got any thoughts? There's a very strong displacement of the distal carina and the mesial carina extends approx. ⅔ down the mesial face of the tooth. The cross section is oval in shape, with no "pinching" at the base. There are also no interdental sulci or apparent enamel wrinkling (thought the enamel is worn, so it's a little hard to tell). Measurements: CH: 21mm CBL: 8mm CBW: 5mm Serration count (midline): Mesial: 5/1mm Distal: 3/1mm Labial face (?) Lingual face (?) Mesial face Distal face Cross section (anterior of the tooth is oriented upwards) Quick scale reference Denticles (distal carina) Denticles *worn* (mesial carina) Thanks in advance, peeps!

I decided to sort through some of the Kem Kem bones I got at the Tucson show, and I think I found several Abelisaurid bones. Please let me know if I got it right (Ifezouane formation, Late Cretaceous, Cenomanian) Here is what I think is a distal tibia Here are some Abelisaurid tibias: A - Quilmesaurus, G - Rajasaurus, I - Pycnonemosaurus @LordTrilobite @Troodon

Hi all, I could not resist and purchased this tooth knowing it would be a tough call to make. It was found in the Hell Creek Fm. The big problem is the worn down mesial carina, there are however some remnant denticles I could measure, but not midline – more posterior. Taking them into consideration the tooth has distal 4.5 denticles per mm and mesial 6 per mm. The other measurements are: CH 1.47 cm / CBL 0.74 cm / CBW 0.39 cm. Based on this and the oval base I am leaning towards Dakotaraptor but might as well be a specific T-Rex tooth position.? I really need someone more experienced to take a look please. Any help is highly appreciated.

What bone is this? Thanks for the help

Hello everybody So I got this small tooth from Hill County, Montana, Judith River Formation, labeled as a Theropod indet. tooth. Length is just around 0.5 inches. CM as seen in the pictures. Any hope for an ID beyond Theropod indet? Thx!

Hi everyone, this is a dinosaur bone I’ve been prepping, it was found on the lance fm in WY, it seems hollow and I was wondering if you could tell me if it’s a T-rex bone or a different theropod species, 8 1/4 by 3 1/2 TIA.

I'd quite like to add a new theropod tooth to my collection. I saw these three for sale, just wondering if they are Nano/theropod as described and not, say, raptor teeth. Thanks Pictures 1 - 3 is 0.56 inch. This has a more oval base, does this mean it's not nano? Because aren't there teeth more rectangular with an indented middle? Pictures 4 and 5 is 0.47 inch -- No pictures of base for this one. Pictures 6 and 7 is 1.06 inch long, but has a repaired tip and is in matrix. Any help will be great. If they check out, I will select one of these. If not, I'll have a browse for some others.

Hello again. Ive been to big brook a couple times and have some more interesting pieces! So here we have two raptor teeth, a dwarf mammoth tusk and a dire wolf tooth...just kidding but hoping there as unique as im saying. The "theropod" teeth may just be worn shark teeth or enchodus. And the other two modern? So 4 things in total though. Thanks anyone.
