Hi All, About 3", this was found by a friend this weekend by the Cape Fear River. We're guessing a jaw of some herbivore, but no clue beyond that! Anyone know? Thanks!

Tried a 1/20 inch sifter to collect sand to take home. Here are my finds.

I found this front bit of carnivore jaw while out on my latest fossil collecting trip in the White River Formation of Colorado. Only one tooth is complete, the canine tooth has broken off. It’s too large to be Hesperocyon and the cross section of the canine tooth does not match that of Daphoenus, which I have previously collected material, including a canine tooth, from. That leaves Hyaenodon and the Nimravids. After doing some comparative research with pictures of skulls, I am tentatively leaning towards this being from a Nimravid, as the contours of the jaw line near the socket where the canine tooth sits are fairly distinctive and match those in the pictures of Nimravid skulls almost perfectly, less so than the contours seen in the skull of Hyaenodon horridus. Plus, the canine tooth is triangular in cross section, and though I couldn’t find any specific references on this bit of anatomy that makes more sense to me for the stabbing canines of a Nimravid rather than the flatter canines of Hyaenodon. But alas, here I am to get other opinions. Hyaenodon or Nimravid? Or something else entirely? (I am fairly confident this isn’t just a piece of oreodont jaw, haha). Thanks in advance.

Hello! Help please with ID. Height - 2,5 mm. Age - Middle Miocene. Location - Western Ukraine. Thanks in advance!

Hi, Mi names is José. I from Piura, a city in the northwestern cost of peru. Together with my friend we find this shark teeth fossil in marine terreins of upper miocene - pliocene in Sechura basin, very similar to Pisco Basin (that may be better known to you). We need help to identify this teeth and others too ( https://drive.google.com/drive/folders/1F6O3ql4zvtRnShPd0ZoOVWJ6tPbOimgr?usp=sharing ) Y1_50 3 --> Isistius triangulus ¿? Y2_328 --> Carcharocles Megalodon ¿? Y1_305 --> Carcharhinus sp ¿? Thanks and sorry for my bad inglish grammar.

I suspect this is just an ordinary bit of flint but I wanted to ask you all for your opinion just in case. I found it amongst gravel on the garden path outside my home in Scotland. The the width of the widest end is 1.4 cm, the thinnest is 0.9 cm and the full length is 3.1 cm.

Hi, I found these teeth washed up on the beach and i'm curious to know more about them. They are covered in what looks like tar. Hopefully someone can identify the kind of animal they belong to, but any kind of information would be great. :-) As far as i can tell, they're some mammal teeth... right?

Hello! Help please to identify a genus. Height - 6 mm. Age - Eocene. Location - Western Ukraine. Thanks in advance!

Hello I have a few dinosaur teeth like these and can't identify them. They are dinosaur and they are from Morocco. At first I thought Carchardontosaurus or Abelisaurus but 1. I have teeth if both and they don't look the same. 2. There is a curve and thickness that reminds me of tyrannosaurus teeth. Any help will be appreciated.

Hello all. I picked up these teeth from a charity shop. I'm pretty sure they are shark teeth, and just bought them to pop in my curiosity collection, but when I was researching I didn't think they were the 'typical' shark style. I was wondering if anyone could help me identify the species it has come from?

Hello! Help please with identification. Height - slightly more than 2 mm. Age - Paleogene - Miocene. Location - Western Ukraine. Thanks in advance!

I am looking for nice chubutensis tooth and I saw this on online. Please help me figure out what this is.. Is this a chubu or meg? I know nothing about locality of this fossil except Southeastern US..

As a dinosaur tooth collector since 2018 I have been fortunate enough to obtain the majority of species I have been looking for in a relatively short space of time. That being said, in the last year I have noticed there has been a severe shortage of high quality dinosaur material available. Not just online but from private collectors too and those that have been available, the prices have shot up considerably compared to a couple of years ago for example. Perhaps Covid 19 is a cause of this. Im just curious as to why people may think this is and their theories behind it. Are people realising the worth of what they have and keeping hold of them? Is material simply drying up in the field? I’d love to hear your views and if anyone else has noticed this shortage in higher end dinosaur fossils, teeth in particular and also the drastic increase in prices for those that have become available (I appreciate prices and specific examples cannot be discussed).

Found this tooth and Peace River would like to know what it's from

Hello! Help please with ID. Length - 7 mm. Age - Middle Miocene. Location - Western Ukraine. Thanks in advance!

How does one reliably differentiate Moroccan Pterosaur teeth from similarly elongated fish teeth? Are there any grooves, striations etc I should be looking out for under a loupe? (Image credit: AJ Plai, http://www.thefossilforum.com/index.php...)

Found at Dauphin Island, Alabama. I found both washed up on the ocean’s shore The light gray tooth is 4.6 cm tall,4.5 cm at it’s widest, and 3.8 cm at it’s base. The dark gray tooth is 5.6 cm tall, 3.3 cm at it’s widest, and 3.5 cm at it’s base.

I am thinking of getting this tooth... The seller said that this is from Judith river formation and it is a tooth of a Tyrannosaurid(Daspletosaurus or Gorgosaurus). Is this real deal?

I bought a tooth of a Carcharodontosaurus from Kem Kem bed, Morocco! Seems like it was broken into three pieces and glued together, and lots of enamel worn off. But it has great size and serrations!

Hi everyone, I got offered this pair of marine reptile teeth as those of ichthyosaurs, but am having a hard time making my mind up about their identification. I'd therefore like to ask for your opinions. The teeth were found during works around Nancy back in 2004, and, based on other ichthyosaur finds from the region, likely dates the Toarcian stage of the Early Jurassic (though, from what I can tell, Oxfordian marine deposits are also accessible in the area). This makes them roughly the same age as material from the Posidonia Shale/Holzmaden and Whitby, but slightly younger than that of the Lyme Bay area. The above photograph is the only one I have, with the seller being on fieldwork and unable to provide much further information for the next couple of weeks. Although we can safely eliminate marine crocodile as contenders for the original owners of these teeth, and I think they are too big to have belonged to fish, I'm undecided on whether these are just highly worn ichthyosaur teeth or plesiosaur teeth. There's something to be said for both. The tall, slender shape of the teeth and their slight curvature, for instance, would seem to fit plesiosaurian teeth, as would, most significantly, the round root of the bigger tooth. In that case, however, the smaller tooth does seem a bit stubby, and the traces of ornamentation along the midsection of the larger tooth surprisingly equidistantly spaced. Generally, the morphology of the smaller tooth to me suggests ichthyosaur rather than plesiosaur. But if that were the case, I'd expect either enamel folds on the crowns themselves, folds on the root, or both (even when ichthyosaur teeth have smooth enamel, I find they still have folds on their roots). I'd also expect the root to be more polygonal in shape, somewhere in the range of triangular to (rounded) square. This is not the case. Now there seems to be some ornamentation midway up the larger specimen which equidistant spacing correlates well with patterns of the folds found on ichthyosaur teeth, thus may indicate the tooth is ophthalmosaurid and therefore Oxfordian rather than Torcian in age. The below image I drew up makes the comparison: As you can see, the match is less then ideal, as the top part of the French tooth is completely devoid of enamel folds, whereas in an ophthalmosaurid tooth the plicidentine folds actually taper out until the enamel is clear. @belemniten, however, posted images of a couple of his ichthyosaur teeth from Holzmaden, one of which appears to show a similar pattern as visible in the middle of the French tooth under consideration here, including what appears to be a round root: However, when looking at other images of the same tooth, it turns out that the root does have folds, as you'd expect from ichthyosaur teeth: Similarly, the below tooth seems to have a superficially similar appearance to the French tooth for the hairline cracking of the enamel, and the fact that enamel appears to be missing from the crown immediately above the root proper (which, again, exhibits folds, however). Still, if the "smooth round root" on the French tooth would've been covered by enamel as well, this would make for a very tall tooth as far as ichthyosaurs go. As illustrated by the specimen below (source), though, ichthyosaur teeth do occasionally have round roots: Moreover, the folds on the root don't always run the full height of it (image source): Lastly, as the specimen below demonstrates (source), the entire root can look completely smooth, presumably from wear: As such, I'm wondering whether the French tooth specimen might not be a very worn ichthyosaur tooth, with its parts being composed as such: This doesn't particularly make too much sense to me either, as the part of the root with folds is rather long and has a very abrupt transition into the remainder of the root. In addition, it raises the question of how the tooth would've gotten so worn. Though I understand there are fluvially exposed sites around Nancy, could this have caused the wear we're seeing. Or would the wear rather be peridepositional? So, I guess I can summarize my questions as: Do these look like plesiosaur or ichthyosaur teeth? If plesiosaurian, what would the equidistant striations on the midsection of the tooth be? If ichthyosaurian, do these teeth look more ophthalmosaurid or pre-ophthalmosaur? How might the wear I think I'm seeing be explained? Thanks for the help! cc @paulgdls @PointyKnight @DE&i @Welsh Wizard @RuMert @FF7_Yuffie

I spent a couple days this week hunting fossils and sharks teeth around coastal South Carolina. I came across a few fossils that I need help identifying. Any ID or guidance is much appreciated. Images are below.

Are these shark teeth? Their both 3 millimetres so I had to play around with some enhancing and sharpening apps, which the grainy rock does not help. I’m also currently working on getting microscopes for my IPhone to help take good photos of smaller finds. But if it’s even possible to identify I’m wondering if their shark judging by the shape and texture. Any input would be appreciated but I understand it’s almost impossible to identify them it’s these photos.

I went shark tooth hunting on the 8th of May. When I got to the shore, I decided to fill a ziplock bag with the sand and shells to take home and search for small fossils later. I’ve never done it and was curious in what I would find.

IMG_0290.HEICHello! I recently went to Venice Beach, and I was hoping to ID my findings. One of which seems to be a large tooth without enamel, but I’m not completely sure. Let me know your thoughts on my haul! IMG_0291.HEIC IMG_0292.HEIC
