Martijn Posted October 25, 2009 Share Posted October 25, 2009 This tooth is found Austin, TX Eagle Ford Gr, South Bosque Shale. I thought about a oversized Cretolamna appendiculata. I hope some of you guys can help me out a bit Greetings, Martijn Qua patet orbis Link to comment Share on other sites More sharing options...
Megaselachus13 Posted October 25, 2009 Share Posted October 25, 2009 I think it could be a Cretodus. Link to comment Share on other sites More sharing options...
Kevin Anderson Posted October 25, 2009 Share Posted October 25, 2009 Looks like Cretodus crassidens to me. Link to comment Share on other sites More sharing options...
Tony Eaton Posted October 26, 2009 Share Posted October 26, 2009 Other than cretodus, I am wondering if this is cardobiadon? Link to comment Share on other sites More sharing options...
Martijn Posted October 26, 2009 Author Share Posted October 26, 2009 Hi Tony, I know about the Cretodus crassidens, but never heard of a cardobiadon. Do you have any pictures or links? Greetings, Martijn Qua patet orbis Link to comment Share on other sites More sharing options...
Tony Eaton Posted October 27, 2009 Share Posted October 27, 2009 Ah, sorry, I am a terrible speller and it shows with words that don't work with the spell checker. Try searching under: cardabiodon Cardabiodon seems to be a relatively newly described species. Link to comment Share on other sites More sharing options...
siteseer Posted October 27, 2009 Share Posted October 27, 2009 Looks like Cretodus crassidens to me. I agree. Cretodus has those folds in the enameloid at the base of the crown on the labial side. The folds on that tooth seem deeper than I have seen before. That's a nice specimen. I have two with very similar preservation/coloring from a Texas site ("Midway Drive"). Cardabiodon is the genus that includes the tooth form once called "Cretolamna woodwardi" (see Welton and Farish's book on Cretaceous sharks of Texas). It seems to be uncommon at most of its known localities. Some are known from Texas and Kansas (a friend has a beauty from there). I have a South Dakota tooth that I think is Cardabiodon.

Martijn Posted October 27, 2009 Author Share Posted October 27, 2009 I think I can agree with C, crassidens for now. Thanks to you all for your help! Regards, Martijn Qua patet orbis Link to comment Share on other sites More sharing options...
