Edit* Title changed to say shark skeletal elements ( previously said bones). This is an interesting topic that was brought up by my mentor and vertebrate paleontology professor during a lecture about a year ago. He mentioned that for some reason there seems to be a higher occurrence of shark bones and relative scarcity of teeth in the Astoria formation. That is the verbage he used. I am willing to bet this is some kind of collection bias where people just aren't recognizing the teeth as often as skeletal elements for some reason. I haven't been able to find information on Google scholar or really anywhere else that has provided information on depositional environments that would favor the preservation of shark skeletal elements over teeth, especially where there are plentiful well preserved invertebrate shells. Most of the fossils are locked in concretions or embedded in concrete-hard sandstone. There is intermittent softer sandstone and siltstone, but seems like most of the vertebrate and invertebrate fossils occur in the harder layers. This is something that has interested me as a research topic, but I haven't been able to make it out in awhile to do any collecting of my own. It would be interesting to set up a transect say from Newport to Lincoln City, take a group out and just collect fossils over a period of time across the transect to get an idea of fossil type, frequency, etc. And see if there really is something lending itself to a higher frequency of shark skeletal elements. On a side note it does seem like there is an usually high occurrence of young vertebrates such as pinnipeds and whales in the sections of the formation I've collected. It would be interesting to hear your thoughts on the matter as well as any additional insights you may be able to provide. What do you think?

Hello all, Can someone please tell me what animal this tooth belonged to? 4 centimeters - around 1.6 inches Found on the beach: Zandmotor, The Netherlands. Thank you!

I'm pretty sure this was found by my friend on the North Sulphur River. It was labelled as such, along with some fish vertebrae I know are also found there. Most of the teeth are missing, broken off on their trip down the river. I'm wondering if anyone can give me more information on this piece. Thanks for the help!

Curious if anyone has any ideas as to what these might have came from. Found this piece in SE Colorado that has tons of shark teeth but these are way different than anything we have found so far.

Below are two Pleistocene mammal teeth from "river gravels" in Florida. I have to further information on their age or locality, unfortunately. The left was merely identified as a "mammal tooth", and I strongly suspect it is from Trichechus manatus, but I have very little experience with mammal dentition and as such thought it would be best to check with someone with greater expertise in the field first. The right tooth was identified as a "peccary tooth", but given the fact that a number of tayassuids were present in Pleistocene Florida I wondered if the tooth could be identified to a genus, or better yet a species level. I will now take the liberty of "@ing in" a few people: @Harry Pristis and @Shellseeker Thanks in advance for any proposed ID's Othniel

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

I found this tooth at El Capitán Beach on the coast by Santa Barbara in the mid 90’s. Any idea who lost their tooth? I’ve wondered what animal this tooth belonged to. Can anyone help me identify it?

Found these two in south carolina near the Summerville and Charleston area, im fairly certain one is a tusk but if anyone could give more details on which type on elephant it could’ve been since im not familiar with the area. The second one is a horse tooth (I think) but I am a primarily florida hunter so I would like to know if its a three toed horse or another species since it looks different then the ones ive found down here.

One of my favorite Lee Creek finds, a nice seal jaw with 5 teeth. This must have been a fairly young individual because there is almost no wear on the teeth. -

Hi. I got this tooth before. All i know is "it is Pterosaur's tooth". I don't know about where it from and genus, species. Can I know the species and genus or family of the owner of the tooth just by the picture? I don't know anything about Pterosaurs.

Hi, I´m an artist and designer of "dinosaur and fossil based sculptures". I have a customer from Seattle who would like to buy a sculpture from me with real Spinosaurus teeth. I buy the teeth from a shop in Spain. Is there a problem to send fossils into the US? Thanks! Timo

Hey, i got some mammal teeth ID vibe going thx to @citronkitten's post. I'm kinda in the dark about these two teeth. As they wash up on the Schelde river shores in Antwerp i'm not sure on their age tho. Both look like front teeth to me. 1. 2,9cm x 1,3cm x 0,8cm 2. 2,6cm x 0,8cm x 0,6cm Thx in advance!

Next grouping is mammal teeth! Hoping to get confirmation on these few; my others are quite similar, so once labels are confirmed I can positively identify the rest, as well. I will divide this into multiple posts - 1 per tooth - to hopefully make it easier to read. 1. camelid? Palaeolama mirifica

Next shadow box from Peach River 26/12/23: Mammal Teeth. Teeth are hard! Still working on IDs, but this is current progress. -
Can anyone identify what these might be? The 1st one is 1 of hundreds found identical to it but of different sizes. There seems to be serrated teeth like a very fine saw blade on the edges of the spike shaped rock.. They are all exactly the same. And the other 1 looks like the head of like a turtle or something. You can actually see a tongue inside the mouth. It looks like it suffered an injury & its head was smashed in . Looks to have skin on the outside & a bone inside the neck. Also teeth inside the mouth. Its for sure some kind of creature. Just don't know what. Thanks in advance.
