MaximusTN Posted April 18, 2019 Share Posted April 18, 2019 The shark teeth shown in the pics were recently found at the WM Browning Cretaceous Fossil Park in Frankstown, MS. They appear to be different than some of the more common teeth found there (i.e. goblin shark). In the publication that was produced for the park, the closet match appears to be Otodus appendiculatus, but I am not finding exact matches online. Of the four teeth, 1 (more triangle) and 4 (recurved, more pointed cuspids) stand out. Any thoughts? Link to comment Share on other sites More sharing options...

The 4th is probably a sand tiger, something like Carcharias samhammeri. 1 ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...

suchomimus20 Posted April 19, 2019 Share Posted April 19, 2019 i think it might be a extinct mackerel shark either Archaeolamna kopingensis (first picture below) or Cretolamna appendiculata (second picture below) Link to comment Share on other sites More sharing options...
Darrell Barnes Posted November 12, 2019 Share Posted November 12, 2019 I think they are upper teeth of the Scapanorhynchus, goblin shark, as viewed on pp. 28-29 of the Manning and Dockery publication from 1992. Link to comment Share on other sites More sharing options...

Scapanorhynchus teeth will have enamel folds on the lingual surface while Serratolamna are smooth. Serratolamna teeth have an asymmetrical root on the lateral teeth. You can see that asymmetry on the middle two teeth. The first tooth is a lower anterior. Link to comment Share on other sites More sharing options...
