Below are 3 "teeth" I found yesterday in North Carolina's Black Creek Group, and I am no expert in identifying dino teeth. The first one is obviously hadrosaur, but not sure if more can be known about it. The second one, it's general shape looks like a "tooth", but honestly I'm not sure whether it is or isn't. It looks somewhat similar to pachycephalosaurid teeth I looked up online, but such teeth are rare and not known from Appalachia, so I'm doubtful. The last "tooth" looks to be therapod, but there's no enamel. The base where it's broken off looks similar to the breaks I've seen in some other therapod teeth in nicer condition, but as I said I am no expert in dino tooth morphology. Could well be a rock, but if so it's an odd-looking rock. All 3 teeth with scale: Tooth #1: Tooth #2: Tooth #3

Hi, This is a big bone from Ait Hani in Morocco (according to the seller), that is about 44cm in length. I don't know if it is hollow but I think this could be a limb bone from a Theropod or Sauropod. Want to ask as someone here might know better. It could be from something else but to me either a Theropod or Sauropod seems to be likely. Thanks!

I've seen this listed as an unidentified partial theropod hand claw from the elrazh formation, Gadoufaoua, tenere dessert Niger. I can't see any red flags but I'm Leary of claws.. the bone structure looks right to me but what do people here think? It's 4.5 cm long

Hi all, This tooth is from Tegana fm, Kem Kem. I'm thinking it's a morph 10. The mesial carina seems to extend to the base, although it really thins out and gets dense (so I don't think it's a premax). Any input is appreciated. CH: 35mm CBL: 16mm CBW: 10mm Mesial serration density: 2.2/mm Distal serration density: 2.0/mm

This tooth is from Tiouraren Hill, Téneré Desert, Niger. I thought it may have aff to ceratosaurs and, looking up the formation, might it be Spinostropheus?

Hey all, If you have a chance, I'm curious to hear your thoughts on this 0.8" tooth I got a while back. I've had it in my nanotyrannus grouping, but I can across it again recently and I think it probably too slender and too high of a DSDI. Maybe just a theropod indet. From the hell creek formation, Butte Co, South Dakota CH: 20mm if I include the whole thing, 17mm if I leave out some of what looks like root. CBL: 8.6mm CBW: 3.5mm Mesial serration density: 5.6/mm Distal serration density: about 4.1/mm Note that the base is caved in on one side and slightly on the other side too. But there's probably still some pinch.

Hi everyone! I have my eye on an interesting claw from Hell Creek in Carter County Montana on "that website" and was wondering if anyone could give some extra insight. The seller listed it as Alvarezsaurus, which I had honestly never heard of before, and a quick search revealed that genus is much older than Hell Creek and from South America. I think they might mean it's from the Alvarezsauridae family, but in any event before I try for it I figured I should ask for an outside opinion on what this is from since this group is new to me.

Hello! I found these foot bones (called tarsals I believe?) from Wibaux county Mt in the Hell Creek formation. The seller says that there’s a possibility these are theropod bones, specifically saying bone 1 might be a dromeosaur bone, and bone 2 could possibly be from a tyrannosaur. I looked at some photos online and the only real difference I could tell is some of the dromeosaur bones could be proportionally longer. I also don’t know how to tell if these are even from dinosaurs or some other reptile/bird. Any help would be appreciated! Thanks.

Hey all, What are your thoughts on this on this one? Thanks, as always, for your help! From the hell creek formation, Hill County, Montana CH: 13.5mm CBL: 7.2mm CBW: 3.0mm Mesial serration density: about 5.5/mm Distal serration density: about 4.5/mm

Hey all, Do you think it's safe to say that this fella went mouth-to-mouth with a contemporary (antemortem) and got the other's serrations stamped on the tip of his front tooth? In this first pic, it almost looks like the tooth got raked against another's serrations, starting or ending with the point of significant imprint.

Hi all, If you have a chance, I'm curious to know what you think this tooth from hell creek, SD likely is. I don't have a provenance, but the seller does the digs themselves is exclusively in the Hell Creek. It was labelled Dromaeosaurus, so we know it needs an fix. I think the thing I'm struggling most with is whether the very weak fluting (or shrink wrapped appearance) is sufficient to call it Acheroraptor rather than Nanotyrannus. I'm thinking that the strong recurve also suggests possibly Acheroraptor. The base has enough pinch that Dakotaraptor is probably out, but I'm not sure Acheroraptor is out too. The denticles look a bit chisel, but I believe Acheroraptor can look this way. But, all things considered, it may most likely be Nanotyrannus. CH: 16mm CBL: 8.5mm CBW: 4mm Mesial serration density: 5/mm Distal serration density: 4/mm Here it is in the middle of my suspected Acheroraptor teeth. It'd be quite large for that species. The CHR might have caused me concern, but the tooth on the far right is pretty clearly Acheroraptor (fluting) and probably has an even lower CHR. Thank you!!

Kem Kem dinosaur bone
BirdsAreDinosaurs posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi all. This specimen is advertised online as a dinosaur metacarpal from Taouz. I don't know much about Maroccan dinosaur bones, but I wouldn't be surprised if this bone a complete fake, composited or heavily restored (some areas appear very smooth) item. Pictures are pretty bad, but it is all I have got. What do you think? If it is real, would it be possible to id it to some level? Thanks!
-
Hey all, During a discussion about different locations in the Kem Kem, this tooth came up. It always puzzled me, but I figured it was just an odd Carch tooth. But the reaction I got sounded like it was worth taking some better pics of. Any thoughts? Kem Kem is all I've got CH: 26mm CBL: 16mm CBW: 7.75mm Mesial serration density: about 2.75/mm Distal serration density: about 2.75/mm Thank you!!

What type of claw could this be? Theropod or Sauropod or something else?
msantix posted a topic in Fossil ID
Hi, Was wondering what type of claw this could be. It isn't complete and quite small at just over 4cm, but it looks robust which makes me think maybe either Theropod or Sauropod (or maybe croc). It comes from the Elhraz Formation, so maybe if theropod, Suchomimus might be an option. Is something like this identifiable and could it be a hand claw? or is there a lack of papers about claw fossils from this formation. Thank you! -
Hell Creek Theropod teeth id help Raptor? Troodontid? Nanotyrannus?
jikohr posted a topic in Fossil ID
Hi everyone! I recently acquired some really interesting little Theropod teeth from the Hell Creek Formation of Carter County Montana. I have my suspicions on IDs, but I would really like a second opinion. Tooth 1: My first thought with this little guy was Troodontid, but I have no experience with Troodontid teeth. It might also be a really tiny Dromaeosaur. No serrations or even a trace of serrations on the mesial side is kind of a unique feature. It doesn't look like they were there and wore off either, it looks like there were never serrations on that side. Tooth 2: I posted a similar tooth before awhile ago. It was also kind of a mystery. This one's a fair bit bigger though. I've heard rumblings of a "third Hell Creek Dromaeosaur" similar to this. Of course it could also be a Nanotyrannus. Tooth 3 and 4: These are really interesting. I initially thought they were Nanotyrannus, but much like the first tooth there is no trace of serrations on the mesial carina and it seems there also never was. Tooth 4 has some wear on some parts of the carina but other places are without wear and have no traces of serrations. Meanwhile tooth 3 has a great carinae and no traces of serrations. Another member showed me pics recently of Dromaeosaur teeth similar to this and I'm wondering if these are Dromaeosaur anteriors or I'm just imagining things and their little Nanotyrannuses. Any insight is greatly appreciated as always!

Hi everyone! I acquired these two pretty recently and immediately though Juvenile Rex, but after that other one I figured I should be more careful and ask for a second opinion. Both are from the Hell Creek of Powder River County, Montana. Tooth 1: Crown Height: 11 mm Crown Base Length: 5.5 mm Crown Base Width: 5 mm Mesial serration density: 4.5 per mm Distal serration density: 4 per mm Tooth 2: Crown Height: 14 mm Crown Base length: 7 mm Crown Base Width: 5 mm Mesial serration density: 4.5 per mm Distal serration density: 3.25 per mm

Dromaeosaurus from China?

What do you guys think? Full size dromaeosaurus from East Asia I think. Seems too good to be sold

How real is this Theropod claw from the Kem Kem?
msantix posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I have been offered a Kem Kem claw which I think is a theropod hand claw, but when it comes to claws from the Kem Kem, I have little idea on how to spot composites or claws made out of carved bone (or at least, I worry too much about Kem Kem claws no matter how good they seem). Wanted to ask if someone can help me determine if this claw is real, and if so, are there any repairs done on it. Thank you!

I found something from our favorite auction site that looks very interesting, however I have my doubts if it is legitimate or allosaurus, and would like to hear someone else's input. Seller describes the item as a fused humerus and radius, but I am guessing they mean ulna and radius, of an Allosaurus, found in the morrison formation. Do anyone have information regarding whether these bones even fuse in theropods, or whether they even resemble the ulna/radius bones of Allosaurus? Thanks

I got another odd man out in my hell creek group. What do you think? The hell creek formation CH: 11mm CBL: 6mm CBW: 3mm Mesial serration density: about 5.5/mm Distal serration density: about 4/mm Serration shape: Hard to tell, given that it looks like half of each denticle is worn away Base cross-section: Almond Mesial carina: Straight Thanks in advance!

Hello, So I came across this seller offering a “Dromaeosaurus tooth”, and I was wondering if it was properly ID’d. The serrations are pretty worn up front, so I’m unsure. The only locality that I can get is Judith River Formation, Montana. (IIRC, Dromaeosaurus isn’t found in the Judith River Formation.) The dimensions of the tooth are 1.3 inches long, 0.2 inches wide, and 0.1 inches thick. It’s been a little while since I’ve last posted here, because I was busy with life and university. Hopefully I did things correctly.

Hi Everyone! I've been looking around at some potential Allosaurus teeth I'd like to buy but before I do I'd like to make sure that's actually what they are and learn how to id them, as I'm assuming the Jurassic fossil market is as rife with misidentification as the Cretaceous one. Here's one I'm curious about, very clearly a Theropod tooth. Apparently found in the Morrison Formation of Washakie County, Wyoming and measures 1.08 Inches in a straight line measurement. So what do you all think? Is it Allosaurus? How do you know? Is it even possible to pin a Morrison tooth on Allosaurus or is there some other obscure genus with nearly identical teeth in that formation I don't know about like a Daspletosaurus/Gorgosaurus "Tyrannosaur indet." situation? Any insight on this would be greatly appreciated.

Listed as a partial tibia and being hollow, possible theropod? Very small--just under 1inch. Is there any other possibilities for such a small, hollow bone? Could it be a type of small reptile for instance? Also, is it Tibia, or another type of bone? Wealden Clay, Hastings Sub Group Thanks for the help

I bought these two teeth at an estate sale in a neighborhood in the CA Bay Area.
BigDaddyTuesday posted a topic in Fossil ID
Sorry if I break any rules or etiquette in regard to identifying these teeth. At the estate sale I asked the person in charge of the items about the teeth, and they said they had no idea where they were from or what dinosaur/s it could be. I looked through some fossil websites and they looked most similar to raptor teeth however I am unsure. Thanks in advance for any help! I can take more pictures if that would help as well.
