fossilsonwheels Posted November 13, 2022 Author Share Posted November 13, 2022 (edited) Squalus sp Pleistocene Kanzawa Sagamihara Kanzawa Japan Our only Japanese shark tooth and our youngest example of a Squaliformes. Really nice looking little tooth and one that was previously posted by @Untitled as Ben is who we got this from.

fossilsonwheels Posted November 13, 2022 Author Share Posted November 13, 2022 Echinorhinus blakei Miocene Pungo River Formation Lee Creek NC Not complete but I was looking more at the location as Lee Creek was a location I wanted to add. 1 Link to comment Share on other sites More sharing options...
siteseer Posted November 14, 2022 Share Posted November 14, 2022 Here is a fossil Greenland shark tooth that I traded for early this year or late last year. It's more complete than the one I had before though I was happy to get that first one at the time and it was actually an extra in a trade.

fossilsonwheels Posted January 8, 2023 Author Share Posted January 8, 2023 Squalus sp Miocene Santa Margarita Formation San Luis Obispo Co Templeton, Ca Very nice looking teeth from a new location for us. Link to comment Share on other sites More sharing options...
siteseer Posted January 10, 2023 Share Posted January 10, 2023 Those Squalus teeth are in unusually great condition for the Santa Margarita Sandstone. Most fossils from it are quite water-worn - many toward the point of unrecognizability. Squalus teeth have especially fragile roots. I'm wondering if the Templeton teeth have suffered less transport than those found around Scotts Valley. I don't think I've even seen a Squalus from Scotts Valley but Perry (1994) noted that he'd seen some badly worn specimens with serrations barely visible.

They are in surprisingly good condition as were several other teeth from that location. There was a perfect Squatina and a really good quality Triakis. Biggest surprise was 8 or so Pristiophorus rostral teeth. The colors are great. I have not found any reference to Sawsharks from the Santa Margarita.

MarcoSr Posted February 26, 2023 Share Posted February 26, 2023 Below is an Echinorhinus priscus, Bramble shark tooth (15 mm), from the Eocene, Nanjemoy Formation, of Virginia that I just pulled from matrix yesterday. The tooth is a little beat up, but brambles from the Nanjemoy Formation are really rare. The only reason I took a picture of this tooth is because I was really getting discouraged and frustrated with my setup for taking pictures of insects in amber and decided to try to take a few micro/small shark tooth pictures with the setup to see how the pictures would look. The lighted tracing tablet that I put the tooth on gave me a nice background so I didn't have to do the usual background cleanup of my pictures and the new light I had bought gave me better lighting of the tooth than my microscope LEDs. So taking this picture salvaged a really bad day of trying to take insect pictures. With a little trial and error I should be able to really improve my small tooth pictures with my amber insect setup. I also took a quick picture of an Isistius trituratus, Cookie Cutter shark tooth (5 mm x 4 mm), that I also just pulled from the Eocene, Nanjemoy Formation, of Virginia matrix.

Thanks for adding these to the thread Marco Sr. I’ve never gotten to search Nanjemoy matrix but I know from talking to @sharkdoctor that Brambles are quite rare. 1 Link to comment Share on other sites More sharing options...
fossilsonwheels Posted April 22, 2023 Author Share Posted April 22, 2023 Somniosus microcephalus Pliocene Kattendijk Sands Antwerp Belgium Just got this, an upgrade with some root intact. I haven’t been finding many Squaliformes late so I’m happy to have something to add to the thread. Link to comment Share on other sites More sharing options...
