I have been trying to finish up my ID's of small teeth I collected last year from Moss Creek in Texas (near the North Sulphur River). This material is Upper Cretaceous, Campanian and I have found at least a dozen genera of sharks with Cretalamna, Scapanorhynchus, Pseudocorax and Squalicorax being the most common forms. I'm going to start with seven teeth that I think may be the same but I can not put a name to. I have been through the references I have specific to this formation or age, elasmo.com, and many very helpful posts on here, but I am still at a loss. In Welton and Farish, they look most like Microcorax crassus, but those are supposed to be somewhat older, and even then there are still some differences. They may be posteriors of one of the more common forms, but I have not found a good match yet, so I'd appreciate some help. I'll tag a few a the folks I know are usually pretty good with this stuff: @Al Dente, @MarcoSr, @ThePhysicist, @fossilsonwheels and a couple I know have collected here recently: @EPIKLULSXDDDDD, @Ironhead42 I do not see any serrations or nutrient grooves on any of them. My pictures from above did not come out very well, so I'll just post a couple (with matching numbers from above) that I think show the patter most of them have (flat on the one side and quite convex on the other with a more expanded root). Thanks for any advice you can offer. Mike
