The Amateur Paleontologist Posted June 7, 2022 Share Posted June 7, 2022 (edited) It would be helpful to have a scale so we can see their size. 13 hours ago, Fatigued_Fossil_Hunter said: Eagle Ford Group, Post Oak Creek, Sherman, TX, USA I'm curious to know the identity of these shark teeth so help from experienced fossil hunters would be much appreciated! Cretalamna does seem like a reasonable guess for these ones, I've seen similar Cretalamna teeth reported from the Danish and German chalks Edited June 7, 2022 by The Amateur Paleontologist Opalised fossils are the best: a wonderful mix between paleontology and mineralogy!

ThePhysicist Posted June 7, 2022 Share Posted June 7, 2022 Hello and welcome to the forum! 1. I think the first one could be Cretodus, but would like to see it from the side. The root should look like a shelf: 2. I agree with @The Amateur Paleontologist, the second is Cretalamna appendiculata - a nice one for that site. The remaining teeth (except the last) don't have much to go on, I would call them indeterminate lamniforms. The last one could be Ptychodus, I think I can see a hint of the beaded ornamentation of the enamel. Forever a student of Nature Link to comment Share on other sites More sharing options...
