aek Posted December 31, 2017 Share Posted December 31, 2017 I went to the Waco Research Area a few days ago and found my first shark tooth and some nice ammonites. I know nothing about shark teeth, any ideas on this one? Link to comment Share on other sites More sharing options...
fossilized6s Posted December 31, 2017 Share Posted December 31, 2017 Possible Cretolamna appendiculata, but I'm not great with shark teeth. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
sharko69 Posted December 31, 2017 Share Posted December 31, 2017 I would say Cretodus more than likely. But need to see some other angles. What is the size? Link to comment Share on other sites More sharing options...

Macrophyseter Posted December 31, 2017 Share Posted December 31, 2017 I'd agree with Cretodus. The cusps just seem to be in the perfect size for one, and if it were to be Cretolamna, I would be expecting larger cusps. The shape of the root, the root-crown proportions, and the stretch of the crown itself also makes me lean towards Cretodus. Nice find! 1 If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM! Link to comment Share on other sites More sharing options...
siteseer Posted January 10, 2018 Share Posted January 10, 2018 I think this could be a Cretalamna lower anterior. I don't see the wrinkles/vertical ridges on the basal part of the labial crown you would expect on a Cretodus. 1 Link to comment Share on other sites More sharing options...
Anomotodon Posted January 11, 2018 Share Posted January 11, 2018 I also think this is Cretalamna. I am not 100% sure, but it looks like C. ewelli, that is known from Coniacian of Kansas. Is it Cenomanian-Turonian? This tooth looks more similar to C. ewelli than to Cenomanian C. catoxodon or Turonian C. appendiculata.
