Cloud the Dinosaur King Posted February 13, 2018 Share Posted February 13, 2018 Another sharks tooth. Any ideas on this one? Doesn't look to be another Tiger Shark tooth, but I could be mistaken. Link to comment Share on other sites More sharing options...

Macrophyseter Posted February 13, 2018 Share Posted February 13, 2018 Just for some knowledge you can use in the future, upper lateral Hemipristis (snaggletooth sharks are still alive!) teeth are often characterized by a curved blade and very, very large coarse serrations, and as far as I know, the serrations are larger on the concave side. Lower teeth are more spear-like but still retain the large serrations. If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!
