TeethCollector Posted July 28, 2021 Share Posted July 28, 2021 I have a rooted Carcharodontosaurus indet tooth and trying to determine which part is lingual and labial. I know I can determine lingual side and labial side by using the curvature of mesial and distal, but this tooth is kinda confusing... Thanks Mesial distal One side with groove Another side without the groove Crown Link to comment Share on other sites More sharing options...
Troodon Posted July 28, 2021 Share Posted July 28, 2021 These lateral teeth can be pretty uniform. Unfortunately the tooth does not have a resorption pit which easily determines the lingual side. It does however have both a lingual & labial depression in the root. The base of the root concave curvature is on this side so I would guess this is the lingual side and allow the replacement tooth to come up. Just a minor ID point you identify the tooth as a Carcharodontosaurus indet. Its really a Carcharodontosaurid indet since we cannot determine what genus it is only family. 1 Link to comment Share on other sites More sharing options...

Were there Carcharodontosaurid theropod in the Kem Kem other than C.saharicus? If this is a Carcharodontosaurid tooth and C.saharicus is the only one from Kem Kem, I think this can be identified as C.saharicus .. Link to comment Share on other sites More sharing options...
Troodon Posted July 28, 2021 Share Posted July 28, 2021 Sauroniops pachytholus is the other Carcharodontosaurid in the Kem Kem Group Link to comment Share on other sites More sharing options...
TeethCollector Posted July 28, 2021 Author Share Posted July 28, 2021 Then this is a Carcharodontosaurid Indet. Thank you Troodon! Link to comment Share on other sites More sharing options...

The holotype of Sauroniops did not include teeth so we really dont know if they have different characteristics but its unlikely if you look at Carcharodontosaurid teeth from South America. So those sellers that label teeth as C. saharicus or the African Trex are inaccurate. Unfortunately misinformation abounds with sellers when it comes to Morrocan teeth. Many call Abelisaurid type teeth as raptor. We most likely have multiple species of Spinosaurids yet everyone calls them S. aegyptiacus. Finally you see lots of Deltadromeus or Dromaeosaur teeth being sold yet we are clueless in what they look like. Also collectors encourage these practices since teeth with species names or "raptor" sell better than family names. 4 Link to comment Share on other sites More sharing options...
