PrehistoricFlorida Posted January 28, 2015 Share Posted January 28, 2015 (edited) I recently picked up some very rare Early Miocene carnivore material. These were all found in North Florida. This photo details the differences between five carnivore species from the Early Miocene. From left to right they are: Desmocyon, Metatomarctus, Borocyon, an undescribed Amphicyonid and Phoberocyon. This is a beautiful lower carnassial from Borocyon. This is a tooth I got it a couple years ago from the same site. This is from a very large species of undescribed Amphicyon. This tooth was just over four inches long. Edited January 28, 2015 by PrehistoricFlorida 1 1 www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...
Harry Pristis Posted January 28, 2015 Share Posted January 28, 2015 Nice teeth, Nate. I don't mean to niggle, but there appears to be only two bear dogs (Amphicyonidae) in your list of five. Desmocyon and Metatomarctus are borophagine dogs (Canidae). Phoberocyon is a bear (Hemicyonidae). Borocyon is a synonym for Daphoenodon, a true bear dog. (That is an impressive carnassial tooth for a wolf-size bear dog.) 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

Shellseeker Posted January 28, 2015 Share Posted January 28, 2015 Ditto with Charlie. Thanks for Sharing, Nate. You have a relatively unique position in seeing, evaluating, and even owning some of the most unique fossils from the state of Florida. I can only dream about bear-dog material.

PrehistoricFlorida Posted January 28, 2015 Author Share Posted January 28, 2015 You are correct, Harry. I am just learning about these species, and erroneously referred to them all as bear dogs. These weird creatures are a far cry from what I'm used to seeing in Plio/Pleistocene mammals. www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...
DylanS Posted January 29, 2015 Share Posted January 29, 2015 Wow that Borocyon carnassial and huge undescribed Amphicyon canine are just gorgeous!!! It must be amazing just to be able to hold one of those very beautiful and extremely rare specimens. Thanks for sharing!!! Link to comment Share on other sites More sharing options...

PrehistoricFlorida Posted January 29, 2015 Author Share Posted January 29, 2015 Thanks everyone. The undescribed Amphicyon canine is incredibly impressive, it's the size of a lion canine. www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...

Harry Pristis Posted February 3, 2015 Share Posted February 3, 2015 You are correct, Harry. I am just learning about these species, and erroneously referred to them all as bear dogs. These weird creatures are a far cry from what I'm used to seeing in Plio/Pleistocene mammals. Well, I was not correct about Borocyon. I reviewed Bob Hunt's paper, and I see that he relegates Borocyon to a subgenus within Daphoenodon. I hadn't thought about the bear dogs much recently, but I should have remembered that because Hunt illustrates his paper with an image of a cast of a Daphoenodon (Borocyon) robustum jaw that I recovered. Your carnassial looks about right for robustum. 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

jasonlwjy Posted November 5, 2021 Share Posted November 5, 2021 (edited) Excellent collection！I’ve also got some interesting images of amphicyon canines! Many of these are undescribed though, but I believe that the largest ones belong to Amphicyon zhanxiangi from China, Ningxia province, which is closely relating to A.giganteus Edited November 5, 2021 by jasonlwjy Wrong words written 1 Link to comment Share on other sites More sharing options...
