I'd gotten this tooth fragment from the lance formation of Weston county, Wyoming, it has some serrations and I think that it might be identifiable. The curvature of the fragment. And with this last one, I'm not sure if I'm doing it right. A photo of the tooth with a millimeter scale to show serration density. (it seems to me that there is around 3 serrations per millimeter) Thanks for any help.

Hello fossil friends, purchased a theropod claw seen in pictures. Approx diagonal distance of claw is ~2.9 inches (7.36cm), measurement "around the curve" is 3.5 inches (8.89cm). One repair done around the middle. Listed as a Bahariasaurus claw found in the Kem Kem beds, but my understanding was bahariasaurus was only found in egypt, or might just be a large example of deltadromeus thoughts? thanks

Hi y'all, found this partial tooth in micromatrix from the Triassic-aged Bull Canyon formation. Serration density looks to be 9-10 / mm on the dc. Could it be dinosaurian?

Here are two addition teeth from the Hell Creek Formation of Custer County, Montana. I believe they are from a juvenile T-rex. The first tooth is either a maxillary or dentary tooth. The second is a either a pre-maxillary or pre-dentary tooth. I would appreciate any thoughts on the taxonomy and jaw position. By the way I use these teeth for teaching Fossil Friday classes to kids. I apologize for the photos; for some reason I was having camera problems.

Places in Texas to look for Acrocanthosaurus material.
AJ the Tyrant posted a topic in Fossil Hunting Trips
I know that Acro stuff is quite rare and hard to come by, but I was wondering what the best spots in Texas are to find such fossil material. I live in the state, so it would not be too much of an issue to travel to a spot or two to hunt for these theropod fossils. To sum it up, my question is: what are the best spots in Texas to legally hunt for and collect Acrocanthosaurus fossils/teeth (preferably without heavy duty tools or machinery)? If there are any, it would be much appreciated if you list the formation and location. -
Here are two teeth from the Hell Creek formation of Carter County, Montana. Both that been Identified by others as belonging to Nanotyrannus. The first tooth is similar to the one I posted yesterday which comes from a different location. The other is a front tooth. I would appreciate any thought on taxonomy and jaw location, including yesterday's post.

Any thoughts on taxonomy of this tooth? It was collected from a horizon in the Hell Creek Formation, Powder River County, Montana that was said to contain Nanotyrannus remains.

Any thoughts on what Family of theropod this tooth might represent? It comes from a trusted source and was collected from the Kem Kem near Taouz, Morocco. Thank you for your comments on my previous submission, especially Troodon.

I’ve been going through some material that I collected this Summer in the Hell Creek of Southeastern Montana. I have this little theropod bone (measures approximately 14 centimeters). It is missing one end and has a little damage to the other. The bone is covered in a layer of siderite. I know that it is not much to go off of but am hoping someone might have an idea what it is. I can provide additional pictures if needed.

I have this tooth that i believe to be a small nanotyrannus but i just want to get confirmation so let me know what you think everyone. Its from the Hell Creek Formation. Garfield Ct. Montana. Its CH is 11 mm Serration count: Distal 12 per 3 mm Mesial 15 per 3 mm The base of this tooth is beat up so its impossible to see if it would have had that rectangular pinch that is characteristic of nano teeth. There seems to be no twist of the mesial carinae In my opinion the serrations look peg like as seen in nano teeth.

Hi everyone! I've got one more tiny hell creek tooth that I need help on. I didn't even think there was any mystery to it until I took a really close look at it. I acquired it as part of a set of Paronychodon teeth which are pretty distinctive looking and at first glance I though that's what this was since it's a small theropod tooth with the prominent lines going up the side (I forget what they're called) and with really nice serrations and wait..... Paronychodon doesn't have serrations. At least I don't think it does. I looked around to see if there have been any documented serrated Paronychodon teeth and the only place I found that said it had serrations also claimed that Paronychodon is three feet long and ninety feet tall so I don't think I can rely on that site. My money is on Acheroraptor at the moment but I'm terrible at identifying Dromaeosaur material so I'd like a second opinion. Tooth is 1 cm long straight line measurement.

Hi everyone! I could really use a second opinion on this one. I'm thinking Dromaeosaur Acheroraptor at first but after looking at more pics I'm not sure if it might be Ricardoestesia or possibly even a juvenile Dakotaraptor. It's Hell Creek, about .35 inches. Serrations don't veer off to one side near the base so I really don't think it's a baby Nano. If pictures from another angle are needed to make an id let me know. Any feedback is greatly appreciated as always!

French Variraptor claw?!
Goldkaiser posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi I’ve seen this claw for sale and is listed as coming from France and belonging to a theropod dinosaur known as Variraptor. Does this look like a theropod dinosaur claw to anyone else?

I found this bone on a fossil hunting trip in North Dakota, it was identified as a theropod, probably a T. Rex. Can anyone verify this claim? Thanks for any responces! (The ruler is mesuring in centimeters)

Decided to attempt some DIY Dino displays today. Happy with how they turned out - as long as my three year old doesn’t get ahold of them. I’m going to try the claw mount with some natural wood, maybe beach wood, in the future and spend a bit more time on it - but the first try worked out somewhat. All personal Montana finds with my buddy and my 12 year old daughter. All teeth are 100% natural except the largest brown one which has some minor repair, and the claws which have tip repair. also - I get that the tarsal bone (?) doesn’t fit the claw, but I’m no purist - and not that smart, and for display purposes in my daughters room it looks cool enough. Maybe if @Troodon wants to donate a proper bone to fit the claw I’ll fix it

Hi everyone! A little while a go I bought some Tyrannosaur tooth fragments from the Judith Hill formation. They all looked correctly identified but this one looks a little funny to me. It's definitely a partial theropod tooth from Judith Hill formation of Montana. I just would like another look at it. It's a little less than an inch long.
-
So. I need an answer before I buy it, it’s listed as a “allosaurus libratus” from the Judith river formation in Wyoming. This makes no sense to me. Is it an allosaurus, albertosaurus, or something else?

possible E. dinops tooth
AJ the Tyrant posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hey! I’m thinking about buying this possible Eocarcharia dinops tooth. I want to make sure that it is completely authentic and correctly identified. It does say it is from the Elrhaz formation in Gadoufaoua, Niger, but I just want confirmation (if possible because identifying theropods from Niger can be quite difficult) that this indeed an E. dinops tooth.

Possible Lourinha Portugal Marshosaurus-like Megalosaurid Tooth
Kikokuryu posted a topic in Fossil ID
I recently purchased a Theropoda indet. tooth from the Lourinhã Formation of Lourinhã, Portugal. I wasn't expecting much initially since it looked like an incomplete tooth and the seller tends to go the safe route with their IDs if it's too vague. But, the serration count was similar to that of the Marshosaurus-like megalosaurid teeth based on @Troodon's guide on the dinosaurs of Portugal. Maybe it's just wishful thinking, but I wanted to see if anyone else had some input before I slap that good old theropoda indet. label on the display. The distal serrations is split down the middle. Mesial serrations were kind of hard to count, but they are at least 20/5mm, the distal serrations are 16/5mm. Not sure if the split serrations are messing with the count, but it should be around that 16/5mm after counting it multiple times with various pictures. I don't know how much further the tooth would have gone had it been complete, but I think the mesial serrations do appear to end before reaching the base. Although I don't know if those serration densities still overlap with other theropods like Allosaurus. Split distal serrations and shape of the base which could be slightly off due to the split serration. Distal serrations. Mesial serrations. Mesial serrations ending? Close up on denticle shape on distal side.

Here is the description of a new welsh theropod Pendraig milnerae. Found in the 1950s in the same fissures as pantydraco, the “new discovery” is a type of coelophysidae and it had laid undiscovered in the drawers of The Natural History Museum in London. https://royalsocietypublishing.org/doi/10.1098/rsos.210915 We are on a roll with Welsh dinosaurs: Megalosaurus (Zanclodon) cambriensis Pantydraco cauducus Dracoraptor hanigani Pendraig milnerae And not forgetting the Triassic mammal Morganucodon watsoni
