Hello All, This is for @Troodon and all other theropod experts. I recently acquired this Femur that is 20 inches and reportedly T rex. I have seen similarly sized nano femurs and this one is more robust and thicker. Polling the community to see it you all think this is Rex. Also, What is the material in the center? It is dark brown and runs the entire length of the bone (the cross section pic has white adhesive on the material in question). Marrow? Matrix? I have sent these pics to Pete Larson and he is MIA (no response yet). Hoping you all can end my debate. Thanks

Hello! I have seen this. The seller assures that it is completely natural and is not polished. What do you think? Is it a good piece? Thank you very much

Hello. I got this dinosaur vertebra from Nemegt Formation. Size 7cm long. It seems like a theropod caudal vertebra. But I don't know exactly what species it is.

So I was walking in the river near my house one day and found what me and my friend think is a jeuvinile theropod tooth. Me and my friend are good with identifying dinosaurs, we love dinosaurs, but I just want to be sure. It's about 5 1/2 centimeters long, maybe 1/2 centimeter tall, and at the base about 1 centimeters thick. I found it in the Arkansas river right below keystone dam in Oklahoma, United States. It got dropped and broke into three pieces and that is why there are cracks in it.

Hi is this a Theropod jaw fragment from the belly river group Canada?

As I'm forever on the look out for unidentified theropod teeth, just thought I'd pop this one up for a second/third opinion. It's listed online as Carcharodontosaurus, but I'm not 100% feeling it. The base width appears to be quite narrow, and the serrations seem to strongly increase in size towards the apex. The larger denticles almost look chisel shaped and there's an apparent lack of interdental succuli present too. Probably just positional variation of a Carch, but always worth a double check. Length is approx. 3.5cm. There are sadly no photos of the cross sectional view. Close up of distal denticles:

I just recently bought this Spinosaurus tooth at rock shop. When I looked closer it had a good covering of dust on it from sitting on the shelf for a long time. Its covered in these weird fibers you typically see that are used to make stuffed animals. I think they may have packaged it weird or something. Does anyone know how to get rid of these so my Spinosaurus tooth will look good again?

Is this a theropod eggshell from the Allen formation Argentina?

Hi, I recently acquired this eroded, agatized vert, collected in Morocco. It was sold as a theropod, but a friend thinks it’s a crocodilian. Is there any way to tell? Thanks!

Is it possible to verify the ID of this tooth? It is marked as Majungatholus crenatissimus from the Maevarano formation in Madagascar. It measures 27 mm. Thanks.

Hello! I call myself Sassy PaleoNerd, I am very much interested in Palaeontology. I specialize in Pterosaurs and Jurassic Fossils from Europe. But other stuff isn't outside my realm of Reason I make skeletal reconstructions of mostly pterosaur, but im currently expanding onto more topics, at the time of posting this I am at 103 skeketal reconstructions. Those of you also active on discord might know me from there already. I myself collect Fossils, I posses many from the Posidonia Shale of Holzmaden, and quite a few from Solnhofen. But I always look out for them wherever I go. Below is an example of one of my non-pterosaur reconstructions ^^

From the album: Judith River fm. Fossil Finds
This Troodon tooth is one of my favorite fossils in my whole collection. I found this at a microsite in Northern MT in the summer of 2017. -
I've been wavering back and forth as to whether this is a Carcharodontosaurid tooth, or possibly something else? The serration shape doesn't immediately scream Carch to me, and the mesial carina extending 2/3 down the mesial face would usually exclude abelisaurids from the mix (along with the concave distal edge). There does appear to also be a "pinch" at the base, judging by the lighting in the photo and what little can be seen of the cross section (unfortunately, this is the only photo available). Any input would be great to help me put this one to bed!

Dino egg-real or fake?
Aaron Livingston posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello again everyone! i received the egg I purchased. I took pics outside in sunlight so hopefully some of the can “shed light” on whether this is real or faked. Again, I greatly appreciate everyone’s input. Thanks! Aaron -
Dino egg-real or fake?
Aaron Livingston posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello everyone! I’m Aaron and I’m new here. I just purchased an egg online. I then started reading about how many fakes there are and now I’m very worried. Can anyone give me the skinny on whether it’s real or not? It’s coming from Malaysia and claims to have been part of a private Japanese collection prior to the 80s. I appreciate all your input, thanks!

I’m not familiar with fossils at all so I need help identifying the specimen in the attached pictures. I found this mineral specimen, or at least I thought it was just a large crystal rock, in 2012 at my stepdads house in Placerville, Colorado(San Juan Mountains, down valley from Telluride). I was moving the rock, accidentally dropped it and several pieces broke off. That’s when I wondered if it was a fossil due to the presence of what looks like dried blood, venous cavities, connective tissue, bone, and skin. It is as if it was frozen instantly and turned into stone and crystal, Medusa reminiscent. The San Juan volcanic field is said to be the largest eruption in the world and the proximity of where I found it could explain the strange preservation (if it is in fact a fossil).

I've come across this theropod tooth from Morocco online. I strongly think it's Carcharodontosaurid, but the colouration and general shape doesn't seem to be too far off from what I've seen of Chenanisaurus (mainly looking at photos of @Troodon's). Just to rule out the chance that it does come from the phosphate mines, could anyone provide any input one way or another? The photos provided are the only ones available, I'm afraid. Tooth measures: 4cm.

Hello every. Im looking at purchasing a new item and wanted some advice before I went ahead. It’s from a good seller and said to be an unidentified bone from the hell creek formation. What does everyone thing. Is it fake? What is it? Kind regards Dylan

Ok so have recently arrived back from Morocco a good friend over there said he would meet up with me in goulmima and which we spent a good number of days breaking open rocks finding ammonites fish remains gastropods reptiles all good stuff and was beautiful camping out there, but I am shifting topic here. I made a contact last time regarding jurassic fossil remains so this time I divulged from the usual kem kem beds (however ended up digging them in a lesser known location close to goulmima) when I arrived there a ton of jurassic bones where present some easily identifiable as sauropod vertebrae, femur ( yes absolutely massive) digit 1 claw but two vertebrae I purchased where not associated with any of the other finds and I am needing a little help. The first one and pictures attached in this section are one I am currently prepping the process section is elongated after the neural spine canal and is approximately 1.3 times the size of the Centrum with one side being slightly concave and the other being flat. Again it might be hard to see the bone as this is being prepped now currently but to my eyes has similarities to a stegosaurus vertebrae. This vert I believe to be dorsal is 10.5 inches tall the centrum at it's largest point is 4.2 inches wide and the depth would be 4

I bought a number of cool little Kem Kem fossils recently. There's a number of quite interesing ones in there. One of them turned out to be pretty special. As far as I know Dromaeosaurid material is pretty rare in the Kem Kem beds. But this seems to be the upper part of a right humerus of a raptor. Other Theropods are generally pretty different and those of birds while more similar also don't match. the bone is obviously hollow but the bone wall is still fairly substantial, which makes me think its Dromaeosaur instead of bird. The bone is also almost identical in shape and size to the humerus of the small Dromaeosaurid Bambiraptor. Though mine is obviously not as complete, but still very nicely preserved in 3D. I feel confident enough to call this raptor that I wanted to share this with you guys. Bambiraptor humerus. Needless to say, I'm really happy with this piece.
