If you know anything about modern white sharks, how big are teeth of this size? The size is 58mm. How big was this great white shark? Are great white shark teeth of this size large?

Primate fossils are very rare. I would really like to see what primate fossils TFF members have in their collections or have collected and donated. Mine have been personally collected, and have been donated, and are posted below. Let me start this post with the nicest primate fossil that I’ve seen, to show what is possible to find. A Messel researcher from Germany, to whom I’ve sent thousands of squamate specimens for study, sent me the below Messel book gratis last year. This is a book full of incredibly preserved specimens from plants, to insects, to mammals, to birds, to reptiles, to amphibians, to fish. Some very well-preserved primate fossils are in this Messel book, including an incredible Darwinius masillae articulated specimen shown in the below picture. After showing that incredible Messel primate, my primate specimens, which follow, seem pretty meager, but nevertheless are of scientific value. First, three primate teeth that I found in anthill matrix, from anthills situated on exposures of the Big Cottonwood Creek Member of the Chadron Formation (Latest Eocene-early Oligocene), from my sons’ M&M Ranch in Nebraska are shown in the below picture within a figure, as well as the cover of the publication that they are described in. Because the researchers were not able to assign the teeth to a genus (see the text in the red box in the below picture) I intend to recollect anthill matrix in the same 3 areas where the teeth were found in hope of finding a more complete primate specimen (at least a partial jaw with a premolar, molars) so the species can be identified. Secondly, a partial omomyid primate jaw, which I found in the Eocene, Nanjemoy Formation of Virginia, shown below in a figure from the paper that the partial jaw is described in (see first page of the paper below). Also note the two excerpts below from the paper. Due to the extreme rarity of this specimen, it is extremely unlikely that I could find another specimen that might be positively identified. From the paper Title and Abstract: "First Fossil Primate from the Atlantic Coastal Plain" From the paper DISCUSSION AND CONCLUSIONS: "Considering its geographic separation from other known North American, as well as European, omomyids, it almost certainly represents a previously unknown species. However, in the absence of premolars (often the most diagnostic teeth in omomyids) or any other anterior teeth, or obvious derived molar traits, it would be premature to create a new taxon for this fragmentary specimen." I am really hoping for and looking forward to TFF member primate posts to this thread. Marco Sr.

I haven’t been tooth hunting in a long time, so I’m scanning through sand from Matoaka beach, Maryland. I’m hoping to get out this year. I always love finding skate or Ray teeth.

I recently found this partial tooth in Florida and I really think it’s dire wolf. It looks exactly like the upper carnassial dire wolf teeth online. The only measurement i have is that the thickest part of the enamel from top to bottom is 17mm thick, not accounting for wear. Can you guys confirm/deny? Thanks! filtered-3F76D20A-199B-4B93-8957-ACB17287FC39.mp4

Distinguishing Borealosuchus and Brachychampsa teeth
Othniel C. Marsh posted a topic in General Fossil Discussion
Is there actually any means of distinguishing Brachychampsa and Borealosuchus teeth, particularly those from the Hell Creek Formation? Insofar as I can see Brachychampsa teeth tend to more globular than those of Borealosuchus, but I have noticed that some Brachychampsa teeth, particularly those closer to the back of the jaw, can be quite elongate, so is there an identifying feature besides shape? -

Mammal jaw from Montana

Hi All, I will be grateful for identification of late cretaceous (probably Maastrichtian) shark teeth found in Nasiłów, Poland. I know that some of the roots are missing and genus may be hard to identify but just the family will be enough in such cases. Thank you!

Hi all! I'm back with what I hope is a helpful video for an ID. The guide thought it was a mastodon tooth. My apologies - I only have an imperial ruler and do not own a printer to print a metric ruler. THERE ARE VIDEOS FOR ADDITIONAL UNIDENTIFIED FOSSILS IN THE COMMENTS. Tooth #1 Tooth1.mp4

Fossilized jaw, gifted to me by my aunt this christmas.
75millionyearsago posted a topic in Fossil ID
The jaw is pictured here- the enamel on the teeth does glint as expected, and there are fragments of shell throughout the matrix. Partially obscured portions of the left side of the jaw also show it was crushed as it fossilized, which all to me indicates the matrix is real. The jaw was sourced from Morocco by my aunt from a trusted seller she works with frequently, so i’m not SUPER worried about its authenticity. That said, if you think something is up, do tell! I’m led to believe it belongs to genus Enchodus, but the angle of the frontal tooth alongside the shortness of the jaw has me really unsure, and is leaving little inklings of doubt about it being real. i also attached a photo of an ammonite i am 100% sure is real but am hoping for a second opinion on my ID as an Agadir ammonite.

If you don’t mind jawboning with me here, what do you think we’re looking at? I collected this from a gravel bar in on the outskirts of the woodbine, more eagleford but this easily could have traveled down the creek. Any help is appreciated! I can provide additional pics, I don’t know what I don’t know, and that includes what you need to see to give me the goods on my goods..lol I need to glue it, just washed it off even though I’ve had it for 2 weeks.

Hey been busy collecting teeth! I have refined my Obliquus set a bit. And tried to put together a couple of Serratolamna ascheroni sets as well. Any feedback, critique or advice on more references or other examples would be welcome.

Hi all, Recently came back from a fossil hunting trip from a Miocene age deposit. Was looking through some of my finds and noticed that what I believe to be sand tiger (Carcharias taurus) teeth have striations on them. I am fairly new to shark teeth collecting and was wondering if only sand tiger's have them as I have not seen them on other genus. Wondering if anyone here that is more knowledgeable could shed light. Thanks in advance.
