  1. 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!
  2. 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
  3. 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!
  4. 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).
  5. 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.
  6. Unidentified theropod bone

    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
  7. Who thinks this Wealden claw (my fossil) is Oviraptorid? What are the diagnostic features, anyone know....Henry?? Looks like it could be either to me - Dromaeosaurid/Oviraptorid. It is interesting that we also have maniraptoran confirmed at this locality, so this is another one to consider when identifying small elements like this. I am finding very small theropod dinosaur bones and claws that could belong to these animals. Currently Oviraptorids are only known from the late Cretaceous! And only in Asia. Yet some forum members have identified this as Oviraptorid...a big deal if they are correct....but are they?! The Wealden claw Dromaeosaurid claw Oviraptorid claw
  8. New Noasaurid From Southern Brazil

    Looks like a new type of Cretaceous age Noasaurid theropod has been discovered in Southern Brazil! https://www.nature.com/articles/s41598-019-45306-9
  9. ¡Hola! Compré este huevo de dinosaurio de China. El huevo mide 20cm y tiene una forma perfecta. Quiero prepararlo para resaltar la cáscara de huevo (tiene mucha cáscara de huevo) ¿Qué opinas sobre su identificación y calidad? Muchas gracias! Hello! I bought this dinosaur egg from China. The egg measures 20cm and has a perfect shape. I want to prepare it to highlight the egg shell (it has a lot of eggshell) What do you think about their identification and quality? Thank you! https://drive.google.com/file/d/1RFQY9_A2utpgT-jLOOHHlQUsNITqMEGK/view?usp=drivesdk
  10. Kem Kem Claw

    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!
  11. That Odd Theropod Tooth

    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):
  12. Carch. Or Abelisaur Tooth?

    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?
  13. I decided last week to keep an eye out for any of those elusive dromaeosaurid-like teeth from the Kem Kem....I think I got super lucky and found one within days!! The morphology doesn't match up with anything I'm familiar with from Morocco, so I'm thinking it fits quite nicely with the general appearance of a dromaeosaur tooth. Apologies for the quality of the photos. I've taken a lot of snaps, but just can't get any super clear shots. The tooth is 13.5mm in height. Tall and strongly laterally compressed, with a definite recurve. Please be my guest at trying to count the denticles; I've squinted and gone cross-eyed trying, but by my best count it's... Mesial midline: 8/9 per mm Distal midline: 5 per mm The mesial carina terminates approx. half way down the anterior edge, and has a very slight twist. You can see where the carina ends in the next photo, as the surface transitions to an almost flat, smooth triangular shape down to the base of the crown (shape reminds me of a tyrannosaurid split carina). Mesial: Distal: Cross-section is "figure-of-8" shaped: "Pinch" at base (present on both labial & lingual faces): Sorry again for the sharpness of the photos. My camera is a potato when it gets to macro photos.
  14. Big Brook - Theropod tooth?

    Pretty new to this. Found this on my first look in the Big Brook in NJ. Based on the even spaced serrations and the cracked enamel look, could this be a worn theropod tooth? About the size of a quarter. Thanks!
  15. Nemegt Dinosaur Claws

    Here are a few more Negmet claws. Not sure what they are. Claw 1
  16. Not much is published on UK theropod teeth so its nice to see this one. Although the teeth are not in the best shape its good to understand what clads are being found. This paper reports on two new isolated theropod teeth discovered on the Isle of Skye, Scotland representing at least two species. https://sjg.lyellcollection.org/content/early/2019/04/30/sjg2018-020
  17. Another small theropod tooth ID

    Hey guys, I have purchased another small theropod tooth from Hell Creek fm. This one is a little bit bigger (0,8cm) and seems to be more slender than the tooth identified by @Troodon as Dakotararaptor. It will be harder to ID since the serrations on the mesial edge are present, just quite worn. Mesial edge count will be tough and rough... The serration count midline for the distal edge is 6/mm. Thanks for any input and don’t hesitate to ask me fore more pictures. Kind rgards .
  18. Robust foot claw from the Kem Kem

    Hi, Another question about a foot claw from the Kem Kem Beds. This is a weird looking claw that may or may not be theropod. It is quite robust and is 7cm in length, though i am having trouble telling which angles of the claw the photos come from. It does look like the underside has a couple of circular depression spots which could indicate theropod, though i am not confident and wanted to ask for opinions whether theropod is the likely candidate. Thanks.
  19. Tiny Hell Creek Theropod Tooth

    I just found this little tooth for sale. It is from the Hell Creek Formation in Montana and is 5/16" long. Assuming that includes the fake root, by measuring on my screen it appears to actually be 3/16" long along the distal edge. Serrations then are about 9 per 1/16" distal and 13.5 per 1/16" mesial and look more rod-like than chisel-like to me. There are no ridges on the sides, so it's not Acheroraptor. Could it be Dakotaraptor? This species has been #1 on my list for a while and I would love to have this in my collection if it is Dakotaraptor.
  20. Hi, I have asked before a couple of times about Spinosaur hand claws, i figured my best bet was to look for a Spinosaur foot claw since they seem to be cheaper and less faked imo. I saw this small foot claw supposedly from a Spinosaur (from the Kem Kem) that looks good, but i know i should post it here before thinking about a possible purchase. The seller says it has minor repair. Thanks in advance!
  21. Odd little Hell Creek tooth

    This is an interesting tooth. It is from the Hell Creek Formation. no county was given only Montana. It is .3 cm and is serrated. It has a very interesting shape to it which i thought was similar to bird teeth but after seeing the serrations, my thought was Richardoestesia gilmorei. I am probably way off in my thinking. At the very least, I thought it was interesting enough to post here and see what other opinions are. Any thoughts ?
  22. an interesting Kem Kem tooth

    I have been working on finding a Dromaeosaur indet tooth from Morocco for a few months. Most of the "raptor" teeth from the Kem Kem beds I have seen labeled as such ended up being more similar to the Abelisaur indet teeth and those I have found were over priced or gone before I could get then. This one is different and appears to fit the general profile of what I am looking for pretty well. I do not think it is a Carch and it does not look like an Abelisaur either. At the very minimum, and hopefully @Troodon agrees with me, it seems a good candidate for a multi-variant analysis. Any thoughts ?
  23. Hell creek small theropod bone?

    I was recently going through some old finds from last summer when I came across this little bone, it is partially hollow and has very porous bone structure. that's why I assume this bone came from a very small theropod. It shares some resemblance to a bambiraptor coracoid as shown in the last picture and is almost exactly the same size. the bone measures 11mm wide in the first picture
  24. Here is a really interesting bone. Despite being pretty small and a partial bone, this would be an excellent addition because you can get a great look inside of it. This is the type of bone that lends itself to some serious teaching I think. It is from Garfield County in Montana, Hell Creek Formation. 1 7/8" x 5/8" x 5/8". It is small and partial but it appears to be in excellent condition. It is listed as a raptor bone and my limited knowledge says that is a possibility. It sure looks like a theropod of some sort (bird, troodontid maybe I do not know). I would love to hear any and all thoughts on this one !!
