Placoderms Posted November 15, 2009 Share Posted November 15, 2009 Devonian fish teeth from the Genshaw formation of Alpena, MI I am trying to put together a display of my fish teeth and jaws I found this year called "Devonian Dentistry". Since I am a novice, identification is the hardest part of this hobby for me. Bob Carr (Ohio University) mentioned the white one might be a coelacanth tooth. I assume the second one is the same. Can anyone confirm or suggest a different ID? Link to comment Share on other sites More sharing options...
Roz Posted November 15, 2009 Share Posted November 15, 2009 Yes it sure looks like one I saw online. Think you have the correct ID Same Tooth Welcome to the forum! Link to comment Share on other sites More sharing options...
Auspex Posted November 15, 2009 Share Posted November 15, 2009 According to this website; http://www.kyanageo.org/Devonian.html I'd say he's got it right (though it might not be this exact species).

Placoderms Posted November 15, 2009 Author Share Posted November 15, 2009 Wow, you guys are good! Thanks! Mind if I keep them coming? I didn't have time to ask Bob about the others I found... Here is another type of tooth (or so I assume): Link to comment Share on other sites More sharing options...
paleozoicfish Posted November 15, 2009 Share Posted November 15, 2009 To be technical, it is the a piece of the anterior tooth whorl of an Onychodont, which is a Sarcopterygian and NOT a coelacanth (although most people make that mistake). Here is a complete one from the Delaware Limestone in Ohio. and here is a link to a picture of a reconstructed skull. http://upload.wikimedia.org/wikipedia/commons/thumb/4/45/Onychodus_Skull_Diagram.jpg/233px-Onychodus_Skull_Diagram.jpg cheers, -PzF Link to comment Share on other sites More sharing options...
