I have been collecting a locality in SC that is Eocene (Priabonian) in age. I have found a squalid tooth (I personally find it most favorable to Squalus weltoni) and 3 squalid-like teeth, however I have no idea what these could be. Unfortunately, the deposit is not kind to the fossils contained therein so they are quite beat up and missing the enamel. The definite squaloid tooth is the bottom one on the graphic, and the other 3 (top and middle in the graphic and the standalone) remind me of a squaloid at first glance, however don't appear to be. There is only one paper on the selachian fauna of this deposit, and there are no teeth comparable to these in said publication. The age is Eocene, Priabonian and locality is in Aiken, SC. The standalone is the same size as the top one in the graphic (~5mm). Any potential leads welcome!

I have decided to create some collection threads for various shark teeth. I would like to use these to promote some of the less frequently seen shark teeth. We see plenty of Megatooth, GW's etc but some pretty awesome sharks do not get much love here. I wanted to set this up by taxonomic orders and see what my fellow shark nuts want to share. I think this is a great way to not only share our collections but also build a database that may help help collectors ID teeth or get some idea of what exists to be collected. I love Squaliformes sharks. They are among the the most biologically interesting sharks to have existed. Among the truly fascinating adaptations they have are bioluminescence, biological antifreeze for extreme cold temperature survival, protruding jaws in one species and even pockets ! They represent the smallest sharks but some such as the Pacific Sleeper and Greenland Shark can grow very large. The Greenland Sharks are the oldest known vertebrates on the planet with life spans of possibly longer than 500 years and are the slowest swimming fish. The Largetooth Cookiecutter shark has the largest teeth per body size of any living shark. They are also weird looking sharks that can capture the eye. Google search Rough shark or Pocket Shark or the Viper Dogfish. They are bizarre looking creatures yet perfectly adapted to some of the harshest environments on our planet. For shark tooth collectors they present numerous challenges. Many are deep water sharks with few known fossil locations. Some types of Squaliformes may only be known from one or two fossil sites. Many are small sharks with very small teeth which add to the difficulty in finding them. Rarity creates demand and my experience has shown me that not only are they hard to find, collectors hold on to their Squaliformes teeth. I am not even sure how far back they go in the fossil record as Fossilworks notes Triassic Squaliformes from France but I found no available information beyond a notation. I apologize for the long introduction and biological information that most of you probably know. I am bored educator with no one to educate about sharks lol I would encourage my fellow TFF members to share not only your teeth but your knowledge and fun facts swimming around your brain about the amazing and weird Squaliformes.

It has been a bit since I have done a post. It has been over a year since I have been out hunting. I am days away for things to open up for me.... finally. I am ready to just live in a creek and look for fossils for weeks. I have been lucky to pass the time over the year looking through matrix from different locations. I was very fortunate and extemely thankful to receive some matrix from @sharkdoctor. These two squalus teeth are from matrix in Calvert Formation in central Virginia. Each of them are just a tad over 1mm. Found this one last week Just found this one tonight

Hi everybody, I found this small tooth, I thought it looked like an interesting Squalus but then I looked on Elasmo and didnt see anything like it. What do you think? Location: round mountain silt, bakersfield CA. The scale is in 10ths of an inch
