I really dont think that a page on fish teeth is warranted No one really cares to look at modern fish teeth and I think that the main article on Fish can take of that Fish teeth in the fossil record imo are porrly represented and fish are mainly known from a few scales or fossilized death plates The only real fossil fish teeth I can think of belong to Xiphactinus audax which can be fairly large but like I said I dont think that warrants an article on them Either way fish teeth arent commonly as collected as sharks teeth are as it is a major hobby with websites around it You dont see too many websites offering fossil fish teeth for sale Of course that isnt a valid idea for not warranting a page but is an idea
