I've collected in the New Jersey brooks for a long time now, and I've found a few pieces of dinosaur material over the years, but I'm interested to know if there are any other public land collecting sites in the US where one can find (and keep!) dinosaur material.

Yangchuanosaurus Theropod Tooth From Shaximiao Formation, Zigong, Sichuan Province, China?
Pliosaur posted a topic in Fossil ID
Hello, I would like to know if this tooth may possibly be from Yangchuanosaurus species. It is from the Shaximiao Formation, Zigong, Sichuan Province, China Formation is Jurassic age and relatively very little material is known from this formation and particularly in China although seems like Yangchuanosaurus has been described from this location et al. (1978) named Yangchuanosaurus shangyouensis on the basis of CV 00215, a complete skull and skeleton which was collected from the Shangshaximiao Formation, near Yongchuan, Yongchuan District, Sichuan. Tooth measures less than 2 inches and the serrations appears too worn to make an ideal identification, although looking at teeth from skulls of Yangchuanosaurus, they do seem very similar , in shape and size Any help would be appreciated! Thanks! -
Is there something wrong about this Theropod tooth ?
Brevicollis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, i saw this Megalosaurid tooth from the Isalo iiib form., Madagascar for sale today. Is there something wrong about it ? It seems to look like If some sort of crust has formed around it, or is it plaster, fill mass ? Let me know what you think about it, before me or someone else buys it.- 1 reply

Hello all! Here I am with yet another question the same as all the other ones I ask. “What is this fossil tooth?” I found it online. I believe it to be a theropod, but can anyone officially identify it? It was found in Hell Creek, if that helps. If I can find out in the next 3 days that would be great, as that is when it is going.

Machine learning identifies possible Deltadromeus tooth
BirdsAreDinosaurs posted a topic in Fossil News
By combining several analytical methods, including machine learning, to assess the diversity of a collection of theropod teeth from the Kem Kem beds, researchers found a tooth that could possibly be assigned to Deltadromeus agilis. https://www.tandfonline.com/doi/full/10.1080/02724634.2024.2311791 https://www.uu.nl/en/news/higher-carnivorous-dinosaur-biodiversity-of-famous-kem-kem-beds-morocco- 3 replies

Hi! This is a 19MM rooted theropod tooth from the KemKem group. Sold as an Abelisaurus. But would it be possible to be a Baby rooted Carcharodontosaurus tooth? Not sure.

Found this tooth in my Aguja Formation micro matrix. It's about 6mm in length. I know it's in really rough shape, and I actually broke it in half attempting to get pictures of the distal/mesial sides. Can anyone give me an idea of what it may be? Could it be a theropod tooth? I don't see any evidence of serrations on either side. Sorry if the pictures are not the best. It was extremely difficult to take pictures, especially after it broke in half.

From the album: Hell Creek Formation Microsite
Identifying features of the troodontid, Pectinodon. The illustration is the holotype, adapted from Carpenter 1982, the color image is a specimen in my collection. These are thought to be anterior dentary teeth; medial/posterior positions lack the lingual pitting, and may have fine serrations at the base of the mesial carina. Carpenter, K. (1982).

Got a new box of mixed KemKem material the other day; plenty of Spino, Carch, small theropod, croc, fish, and other usual suspects, but I can't put a name to this one. I'm fairly sure it's theropod, but since there is so little info available, it's hard to say which one. Anyone recognize this little fella? It's 32mm long by 21.5mm at the widest point; the grid squares are 1"/25.4mm. I can take additional pix if needed. Thanks!

Are herbivore fossils rarer than theropod fossils?
Brevicollis posted a topic in Questions & Answers
Hello, i have a question : are herbivore fossils rarer than theropod fossils? Because i saw many theropod fossils, but nearly no herbivore fossils on the fossil markets, which makes me wonder . -
Hi all, I recently bought this partial theropod tooth form the Lourinha Formation (Portugal). Height ~1.1 cm. The distal serration density is 8-8.5/5 mm, the mesial serration density is 7.5-9/5 mm. Crown ornamentations are present and I think also interdenticular sulci. I looked at an old post of Troodon (see below). Are there any other known theropods from this location, besides Torvosaurus, that have a crown serration density < 9/5mm? Any thoughts?

Hi All, I found this tooth sifting in one of the Cretaceous brooks in Monmouth Co., NJ. during a trip around November last year I wasn't sure what it was at first (initially thought talon possibly from something more recent), however after showing photos to a few local folk more familiar/knowledgeable with the fossils in this area (Thanks @frankh8147!), the consensus was, it's a very compressed Mosasaur tooth. Makes sense as Mosasaur teeth can be found here on occasion, and this tooth has several common features. However, I've had a couple individuals suggest theropod tooth when I initially shared it in a couple groups back in November. This was based on the compression of the root. I'm still leaning towards Mosasaur, but recently a different person brought up the theropod theory, so I thought why not throw it up here for opinion. Multiple photos, some redundant (have done a couple "photo shoots" with this one lol). If photos of any specific area would be beneficial, please let me know. Thanks in advance for your feedback/opinions! Truly appreciate the help.

Found in the Horse Shoe Canyon formation (Alberta) with several bones including theropod teeth. It has the right shape and size to be a claw. Any ideas? About 1 inch long

Found this super, super small claw today. Just over half an inch in length. Looks kind of ornithomimid but I’m not sure. Anyone have a better guess? dinosaur park fm

From the album: Triassic
From the "dawn" of the Dinosaurs, this small tooth represents an early theropod. Unlike the other serrated archosauriform teeth present in the formation, this tooth is ziphodont - thin and labio-lingually compressed - the archetypical tooth form that most theropods adhered to since their beginnings.-

Hi, I saw this listing for a Neovenator tooth from the Isle of Wight UK, found in the Wessex Formation, and was just wondering if this tooth could indeed be from Neovenator, or if it is a theropod indet (might be hard to tell since it is only a partial tooth). Striations partially remain on one side and the tooth is about 3cm. Thanks!

Howdy all, I'm interested in this tooth which has the ID of "Afrovenator abakensis," though the seller makes sure to note that this is not a concrete ID. I'm curious as to how I'd be able to identify this as a megalosaur and possibly an afrovenator. Locality is Nafanfo, Agadez, Niger.
