    • Dinosaur teeth from North Carolina are rare and have only been found in a handful of locations. Other than one well known location, these other sites are kept very close to the vest for obvious reasons. Most North Carolina collectors will never find one.I had originally I.D. this tooth as Dromaeosuarid. However after research and consultation with our resident expert Troodon this I.D. has been debunked. After additional pictures, especially of the base and serration it was determined to be a Tyrannosuroidea idet. The two known Tyrannosaurids from NC are Dryptosaurus and Appalachasaurus. However due to the small size of the tooth the species cannot be determined at this time.

    nice one Six! Did you try the South Carolina dino book for ID?

     

    I have not. I tried to download Dr. Schwimmer's paper on S.C. dino's but, have not been able to. I have sent him several photos by e-mail. 

     

    Do you have the book or a link to it?

    I have the SC Dino book purchased online used. It was cheap. Got the info from Al Dente. I don't think that a pdf is available for a commercially produced book but could be wrong as it's from the American Philosophical Society.

      I don't have a SC dino paper by Schwimmer that I can easily find. Do you have the specific title? I have the Appalachiosaurus paper from Alabama and the Ceratopsian paper from NC as far as SE Dino pubs that are recent.

    Outstanding tooth.  Looks too fat to be Dromeosaurid they are compressed more like a Tyrannosaurid.

    Thank you Frank and for the assistance in revising this ID, after I took the time to take more and better pictures.
