sharko69 Posted October 22, 2017 Share Posted October 22, 2017 Found this tooth in N. Texas. 8mm in length. Eagle ford, upper Cretaceous. My guess would be small Archeolamna but unsure. Thanks for any help. Link to comment Share on other sites More sharing options...
Macrophyseter Posted October 22, 2017 Share Posted October 22, 2017 Hm. As far as I know, Eagle Ford is a Cretaceous formation, usually Turonian and earlier? (May be wrong on the specific age). I think that the tooth could be from a lower posterolateral Scapanorhynchus goblin shark, maybe texanus? Great tooth btw 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...
sixgill pete Posted October 22, 2017 Share Posted October 22, 2017 Looks like Archaeolamna kopingensis to me. Cusps are wrong for Scapanorhynchus.

No real nutrient grove and no striations plus the cusps are too large for S. Texanus. Link to comment Share on other sites More sharing options...
