Sergiorex Posted September 13, 2022 Share Posted September 13, 2022 (edited) Hi all, saw this listing for a tooth, it’s from Meade County, South Dakota and looks to me like either a Nanotyrannus or Tyrannosaurus rex tooth. Want your opinions, I personally am leaning towards Nanotyrannus due to the pinch however it seems to be pretty robust. Thanks in advance measures about 1 cm Edited September 13, 2022 by Sergiorex Link to comment Share on other sites More sharing options...
Nanotyrannus35 Posted September 13, 2022 Share Posted September 13, 2022 I think to identify it as something other than tyrannosaurid indet. , the base would need to be cleaned up. 1 Enthusiastic Fossil Hunter Link to comment Share on other sites More sharing options...
Sergiorex Posted September 13, 2022 Author Share Posted September 13, 2022 Oh, I mean it would definitely make it easier but wouldn’t the compression make it more likely to be Nanotyrannus? Link to comment Share on other sites More sharing options...
Nanotyrannus35 Posted September 13, 2022 Share Posted September 13, 2022 @Troodon knows a lot more about this than I do, but I am seeing a pinch and also from what I've seen on nano teeth, the pointy ends of the base is generally nano.

jikohr Posted September 13, 2022 Share Posted September 13, 2022 Is it anything like this one? I was leaning Nano on it but was kinda curious if it might be indet but then never got around to posting it. I don't have the in-depth measurements on hand since it's packed up on it's way to my new residence. Link to comment Share on other sites More sharing options...
Sergiorex Posted September 13, 2022 Author Share Posted September 13, 2022 They look similar, both indent? I mean I lean towards nano on both but not sure if it can be narrowed to one. Link to comment Share on other sites More sharing options...
Troodon Posted September 13, 2022 Share Posted September 13, 2022 The base photo is awful, out of focus and has matrix on it to hide its overall cross-section shape. If you are buying it assume it's a Nanotyrannus. Get the base cleaned up and let us have another look. 1 Link to comment Share on other sites More sharing options...
