Here is a lovely isolated theropod tooth from USA - the seller lacked all locality data, although he believed it may have been from the Morrisons formation. This lovely tooth is just over 2.5cm long and has 15 serrations per 5mm on the distal side (DC) however serrations on the mid-centre off the medial side have not been preserved. It would be lovely to ID this to some level other than theropod if possible. Serrations on the mesial side only go down 2/3rds of the tooth. There is some restoration to the tooth - if any more photos would be beneficial please let me kno

Camptosaurus bones - ischium, scapula
FF7_Yuffie posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, can anyone take a look at these? A trio of Camptosaurus bones from the Morrison Formation, Big Horn Basin --- Not associated, but all are juvenile. They might make an interesting central display piece for my collection if they seem ok. Are they as described, and does anyone spot any repairs or restoration? First - Ischium, 13.2 inches. -
Dear Fossil forum members, I have recently acquired this bone. It is said to have been found at Mack, Colorado. I suppose it is from the Morrison Formation. The previous owner thought it might be a Stegosaurus neural arch, but now I have it in my hands I see more similarities with a supraoccipital. Especially these: (Eolambia, A and C) https://peerj.com/articles/1872/ (Fig. 12, A. Eotrachodon) https://www.nature.com/articles/s41598-019-41325-8 (Fig. 2, Q, R, S, T and their other sides, unknown hadosaurs) seem similar to me.

This purchase was advertised as an Allosaurus (half) vertebrae obtained from Ernest Shirley inventory. Matches well with exhibits 4,5,6 of the illustration from Charles Gilmore's 1920 report on Osteology of Carniverous Dinosauria... which is considered to be a 5th (?) caudal vertebrae of A fragilis (Antrodemus). I would appreciate any feedback on what details are present in this fossil and perhaps where this may have been collected, as no provenance was provided. There are small pits visible in the side view which may be fossae. I have seen photos of similar looking specim

Hey everyone, How do you tell the difference between the teeth of theropods from the Morrison formation, such as Allosaurus, Torvosaurus, Marshosaurus, and/or Ceratosaurus? Any information is appreciated! Thanks!

Its a solid specimen with interesting internal structure. Does not look like bone. Maybe section of horn sheath or body armor?
-
Bony core present. Much of keratin sheath preserved as creamy green. Bottom has distinct flattened profile and the keratin is heavily fractured (see picture - toe2 left edge, toe3 right edge) Top profile exhibits clockwise curve. Jurassic, Morrison, Four Corners.

This is an un-associated surface find from Brushy Basin so no context to draw on. No discernible internal structure when looking at the fractured end. Obvious symmetry and taper to a flat point. I have not found anything seed-like on the internet that is this large or shaped quite like this. So I am excited to hear back from the forum. I am new to the Fossil Forum and look forward to sharing in the bigger brain of paleontology.

Hello, I saw this for sale and tempted by it, but is it Allo? Seems pretty small to me. And, is it complete? The base seems crooked, so wondering if it may be half a tooth? Labelled as complete but repaired crack. From Morrison Formation. Thanks

Small unidentified theropod tooth from Morrison Formation, Wyoming
Sauroniops posted a topic in Fossil ID
Hello there. I recently received a small theropod tooth from the Morrison Formation, without any ID. Part of the tip is missing/worn out. At its longest dimension, the tooth measures 1,1 cm. The serration count (Both mesial and dermal) are 6-7 serrations per mm, and about 18-19 per 3 mm. Anyone who's got a good guess, feel welcome to drop a comment here, cause I have no clue if this is a baby Allosaurus, or a small Marshosaurus, Ornitholestes, Coelurus or something completely different. -
Hey guys, I bought this on online at an auction for reasonable price, which seemed quite cheap for an allosaurus tooth. The seller wasn’t really sure if this was an allosaurus tooth or not, it was his best guess please tell me what you think.

Hi everyone, I just obtained my first non-Moroccan theropod tooth. It's from the Morrison formation and measures 1 and 3/8ths of an inch. I assume it is from an Allosaurus, because of how common Allosaurus is in the Morrison, but the rarer Torvosaurus and Ceratosaurus are the only other possibilities. It would be interesting to hear some opinions, however the lack of visible serrations presents some problems. @Troodon Thanks in Advance!

I am aware that stegosaurus has scutes under its neck, but is this identifiable. Seller states it was associated with other scutes and the ID was done by a professional. Thanks in advance!
