ced0015 Posted April 25, 2017 Share Posted April 25, 2017 Hey all! I have 2 different types of shark teeth I am having a little trouble identifying. I have a some ideas, but I would like any input y'all may have. They were found in north Mississippi in a cretaceous outcrop. Any help is appreciated!

Darktooth Posted April 25, 2017 Share Posted April 25, 2017 First pic looks similar to Cretolamna appendiculata but not quite right. Second looks like Cretodus crassidens. 1 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
ced0015 Posted April 25, 2017 Author Share Posted April 25, 2017 Could the first be a catshark, maybe Scyliorhinus sp? After looking at pictures of C. crassidens, I can definitely see the similarities in the second picture. Link to comment Share on other sites More sharing options...
ynot Posted April 25, 2017 Share Posted April 25, 2017 Way to big for cat shark. I agree with the id darktooth gave- Cretolamna appendiculata Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough." My Fossil collection - My Mineral collection My favorite thread on TFF. Link to comment Share on other sites More sharing options...
sixgill pete Posted April 25, 2017 Share Posted April 25, 2017 I agree with Darktooth and Tony on the first picture, Cretalamna appendiculata. I think the two teeth in the second picture are also Cretalamna, probably lowers. 1 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...

I have found Cretolamna lowers at big brook that have a similar shape, but I have never seen those teeth with double cusps. Even pics from what others have found. Does anyone know if they can indeed have double cusps? I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
TNCollector Posted April 25, 2017 Share Posted April 25, 2017 I know where you found these! Top Left: Cretalamna appendiculata lower anterior tooth Top Middle: Scapanorynchus texanus upper posterior tooth Top Right: Scapanorynchus texanus upper posterior tooth Bottom Left: Cretalamna appendiculata lower or upper anterior tooth Bottom Right: Cretalamna appendiculata lower or upper anterior tooth (its straight so I cant tell if lower/upper) 1 Link to comment Share on other sites More sharing options...

But, I do agree with the two bottom row teeth being Cretalamna as I previously stated.

They look like pretty typical goblin shark upper posterior teeth to me, the smaller ones in the back of the palatoquadrate. The groove also generally indicates goblin shark. I have always labelled these teeth as goblin, but I may be wrong. Let's try @Al Dente Here is one from the Mississippi Office of Geology, but in better condition. Sometimes the side cusps are attached to the main one. Link to comment Share on other sites More sharing options...

I agree that those look more like Scapanorhynchus posteriors. Cretalamna posteriors are wider than they are high. Link to comment Share on other sites More sharing options...
