I’d like to clean up the micro/macro fossils I’ve been finding so that the the pics will look good. Can they be soaked in vinegar or will that destroy them? Here’s an example of what I’m dealing with.

From the album: Neutache Shoreline
My first mandible with teeth. Complete incisor with nice colors. I labeled it as Ondatra sp. since differences between zibethicus and cinnamonius teeth/mandibles are basically nonexistent. Molar pattern on Muskrat molars are very similar to Meadow Vole molars. However, Muskrats are much larger than meadow voles, so Meadow Vole teeth/mandibles will be much smaller than muskrat. Here is a close up picture of the molar on this specimen: 4/5/24 #VL4© CC BY-NC

Hi All, I'm new to this forum and thought I'd send over images of my theropod teeth plus one extremely impressive sauropod from Madagascar. Hope you like them! Paul

I know it's not teeth but I just used that in the description. it goes all the way around the rock so I assume it goess through it, too. but it might not.

Could someone tell me what these are (first photo)? They were found on late eocene sediments near Vic, Catalonia, Spain. The only other fossil around were corals/sponges (would also appreciate if someone could confirm) like the one in the second photo attached so these stood out.

Hello beautiful people, I would like you to help me label the following specimens, which come from Morocco. In theory, the 3 teeth in photo "A" are from juvenile spinosaurs. Those in photo "B" deltadromeus. And finally those in the photo "C" Tylosaurus. As always, very grateful for your responses!

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?- 11 replies

Hello everyone, another ID-question. We found this at the southern side of the Danish island of Møn, right next in the area of neolithic settlement. I have a hard time identifying this particular part of a tooth/fossilized set of teeth. As we are staying here for our holidays, I have no other scale with me. Any idea, of what we found here, would be greatly appreciated. Best wishes, Jens

Any help would be appreciated.

So, no Kem Kem dromaeosaurids after all?
BirdsAreDinosaurs posted a topic in General Fossil Discussion
Hi all, I just recently had the time to thoroughly read through this recent paper, which describes, amongst other things, how machine learning was used (in combination with other techniques) to identify a possible Deltadromeus tooth. The authors also suggest the presence of a second noasaurid species in the Kem Kem beds, based on a small sub-adult partial vertebra. In the discussion, the authors discuss individual teeth found in the Kem Kem beds that were previously referred to Dromaesauridae by Amiot et al. (2004), Richter et al. (2013), and Ibrahim et al. (2020a). The authors believe all of these teeth do in fact not belong to Dromaeosauridae. They say some are most likely abelisaurid, and others noasaurid (those with strongly distally recurved crowns and those with a non-serrated mesial carina and/or a faint constriction between tooth and crown). All of the dental features used to refer Kem Kem teeth to Dromaeosauridae, are in fact also present in noasaurids and juvenile abelisaurids. To be honest, I never really believed the teeth described in these older papers belonged to Dromaeosauridae. Having said that, there are still some tooth types from the Kem Kem beds that have never been described in scientific literature, which are "dromaeosaurid-like". For example, the ones in Troodon's overview having a twisted mesial carina. However, when you look at lateral teeth of the noasaurid Masiakasaurus, some also have a twisted mesial carina. I think there is still a possibility that some of these small dromaeosaurid-like Kem Kem teeth are in fact dromaeosaurid, but it is quite likely that they all turn out to be noasaurid or abelisaurid. What do you think?- 1 reply

Hi all, Thanks so much for the kind feedback on my Berthasaura reconstruction. Here is another example of my work: A 'juvenile' tyrannosaur skull based loosely on Jane (BMRP 2002.4.1) I'm aware of the debates regarding age and species however I have just approached this as younger individual. Thanks so much for checking out my sculpt. I'm printing a prototype as we speak, I'll post some updates on here once its assembled!

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!
