MarcoSr Posted December 4, 2013 Share Posted December 4, 2013 I sincerely appreciate the feedback and corrections. I was back and forth on the Hexanchus symphyseal vs. E. blakei. Anyone have other Hexanchus symphyseal tooth pics? jon Jon If you Google Hexanchus symphyseal and look at the images you can see a number of teeth. Below are links to two. http://www.fossilsonline.com/index.php?main_page=popup_image&pID=817 http://www.flickr.com/photos/sharktoothcollector/6339059775/ Marco Sr. "Any day that you can fossil hunt is a great day."

sixgill pete Posted December 4, 2013 Share Posted December 4, 2013 I agree with Jess that the tooth on the bottom right on Elasmo does not look like a symphyseal. Here is a pic of one in my collection Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
masonboro37 Posted December 5, 2013 Share Posted December 5, 2013 Great finds! I am in in awe and enjoyed your report and pic's. Thanks for sharing! Process of identification "mistakes create wisdom". Link to comment Share on other sites More sharing options...

caldigger Posted December 7, 2013 Share Posted December 7, 2013 Hey guys, great to hear your trip was a triumphant success. I was the guy you were digging near at the start of the east quarry on Sunday. Looks like we all had a good time. Link to comment Share on other sites More sharing options...
Texas Fossil Hound Posted December 8, 2013 Author Share Posted December 8, 2013 (edited) Texas Fossil Hound, How was the oplegnathid mouth plate identified? It's been a while since I've been to the museum but I don't think that fish jaw form was identified to family in the display case of bony fishes the last time I was there. I know that the genus Oplegnathus was in the latest STH fauna list as of a few years ago but I've never seen the name with a specimen before. I have a couple of those but they were not self-collected (have dug there for years) leaving me to assume they are at least somewhat uncommon if not rare. Jess Siteseer, I found a paper poster earlier on TFF by some folks who had a similar find at STH. I have included it here for your reference. Oplegnathid fish Mouth plate.pdf If you search the word "oplegnathid" in the Fossil Forum, I am sure the post will come up. there were a couple members with specimens that posted. GREAT reference!

Texas Fossil Hound Posted December 8, 2013 Author Share Posted December 8, 2013 (edited) Dave and others - it is an odontocete tooth, but Squalodon (or even squalodontids) has not yet been identified from the middle Miocene of California. These teeth with the bulged root are often identified as Prosqualodon, which is even worse, since Prosqualodon is strictly southern hemisphere. Thanks Bobby! Question, so you are saying the one I identified as Squalodon, is really a toothed whale/cetacean? I have several of these. I called it Squalodon because the BVMNH guidebook of the STH fossils specifically calls this out as Squalodon (Primitive Dolphin). I suppose someone should offer a correction. Do you have any more information on these teeth so I can better ID the ones I have In my collection? Jon Edited December 8, 2013 by Texas Fossil Hound "Silence is Golden, but duct tape is Silver."

siteseer Posted December 8, 2013 Share Posted December 8, 2013 (edited) Jon, There was a thread elsewhere on this site about "Squalodon" being incorrect on the BVMNH labels. Bobby pointed it out then. Jess Edit: Actually, Bobby has pointed out the misuse of "Squalodon" a few times and not just in reference to STH finds - also sites where undescribed material has been informally identified as that.. Thanks Bobby! Question, so you are saying the one I identified as Squalodon, is really a toothed whale/cetacean? I have several of these.
