Hi everyone, I was going through some tiny teeth from a recent trip to Ernst quarries (Bakersfield; round mountain silt; ~ 15 mya) and came across this intriguing little tooth. It is ~11 mm and serrated on both sides. Is this a tiny meg or just wishful thinking?

Last Sunday I stopped at an outcrop of the Maastrictian (late Cretaceous) Prairie Bluff Chalk in western Alabama. About 3 meters below the top of the formation I encountered this tooth. It was definitely in situ, I had to chisel it out. It's 2.1 cm long, 1.6 cm wide at the base, and 0.7 cm thick at the base (so quite flat). Despite some cracking the tooth is not distorted, it is actually flattened not compressed during fossilization. One face is almost flat, and the other is curved. Both sides are serrated until very close to the tip; there are 5-6 serrations/mm. I have an idea of what this tooth is, or what I want it to be, but I have never collected one before so I'd like to get more experienced opinions. One thing that is confusing about this, the Prairie Bluff is a fully marine formation, deposited well offshore in moderately deep water. Associated fauna included a diverse array of marine bivalves, gastropods, echinoids, cephalopods (heteromorph ammonites including baculitids, Hoploscaphites, Discoscaphites, and Diplomoceras, as well as coiled nautiloids), and very scarce shark teeth, so it was definitely a fully marine environment. So, what do y'all think? Don
