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.

Found this example for sale, mostly just want to know if it is a real specimen. Thanks for looking.

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.

Identification of Claws/Unguals from the Hell Creek/Lance Formations
Troodon posted a topic in General Fossil Discussion
A member of the forum asked if I cam put a topic together to help identify claws from the Hell Creek/Lance formation. Its fraught with difficulty since so little has been published and described from these faunas but will attempt to put something together. All subject to discussion and mistakes. Although the focus there is with the dinosaurs of the Upper Maastrichtian its applicable to most of the other faunas of the Campanian and Lower Maastrichtian ages. Ceratopsian indet. This family of dinosaurs include Triceratops, Torosaurus and other large bodied Ceratopsaian yet to be described. Identifying unguals to a Genus/Species level is impossible and these are best identified as Ceratopsian indet. Ceratopsian unguals are best described as being rugose with many pits/holes on the front perimeter of the ungual. There is also a ledge (more pronounced on some than others) on the ventral side as shown by my red marks. I find it difficult to tell the difference between hand and foot unguals of the same size other than the wings are not has pronounced. The more symmetrical the wings are the closer the ungual is to the midline Digit III. Photos are the best way to show what they look like and here are some from my collection Dorsal view Ungual 1 Ventral View Ungual 1 Dorsal View Ungual 2 Ventral View Ungual 2 Dorsal View Ungual 3 Ventral View Ungual 3 An illustration of a Hand (Manus) A photo of a composite foot Leptoceratops indet. A small Ceratopsian in these faunas is a Leptoceratops. Teeth are the most common material found or sold but there are skeletal elements found. Here is an ungual I found in the Hell Creek. The dorsal view is like an isosceles triangle and very compressed. Dorsal View Ventral View Since these are extremely rare here is an additional photo of a associated set of unguals from the Two Medicine Formation An illustration of an campanian foot An illustration of a digit.

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.

I recently saw this available for sale during one of my latest hunts for new stuff. Seller claims it to be a dromaeosaur claw from Morocco (definitely looks the part for Kem Kem material). I am beyond useless with anything other than teeth, so could someone offer an opinion on what kind of claw this might be? Size: 14mm Thanks, all!

So the odd Kem Kem tooth I bought online arrived today. It does have a bit of a funky shape to it. • Chunky with a recurve. • Oval cross section. • Mesial carina naturally extends only to 1/2 way down the mesial face. • Distal carina reaches cervix. • No wrinkled enamel. • No obvious interdental succuli. Denticle count at midline - Mesial: 13/5mm Distal: 10/5mm Close up of denticle shape (distal midline):

This tooth I found online recently has me a bit stumped. The seller lists it as belonging to Bahariasaurus, but I can't find even probable images of a tooth from one to compare. * Forgot to say, it is from the Kem Kem. The denticles don't look too much like an Abelisaurid, but the side profile of the tooth seems a bit odd for a Carcharodontosaurid. The mesial carina also appears to only extend roughly 1/2 down the face of the tooth. Denticle count at midline (from what I can fathom): Mesial: 16/5mm Distal: 11/5mm This is the only photo, I'm afraid... I know how difficult it is to identify anything without detailed photos, but does anyone have any rough thoughts as to what this one might belong to?

Hey folks, Thought I'd run it by the forum experts as to whether you agree with the Carcharodontosaurid label for my new acquisition (which it was sold as)? Locality is the usual Kem Kem beds, Morocco. Serration density- Mesial: 10/5mm Distal: 9/5mm Distal serrations run to the base, while the mesial serrations end about 3/4 of the way down the carinae. It's a chunky little thing, but I gather Carch teeth can occasionally be on the more robust side....but I'll let you judge: Side Views: Base: Distal: Mesial:
