matt4102 Posted December 6, 2020 Share Posted December 6, 2020 These teeth were found in Eastern Montana in Garfield County. I assume they are teeth but don’t know what kind. Would appreciate any info anyone could give on them. Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted December 6, 2020 Share Posted December 6, 2020 They appear to all be shark. The first one is missing a lot of the tooth so I can't tell what it is but the second teeth look like Ptychodus and I suspect the first two in the last picture to be Cretoxyrhina/Cretolamna or some other Lamniform and Cretolamna (probably appendiculata).

Thomas.Dodson Posted December 6, 2020 Share Posted December 6, 2020 The last tooth looks like Squalicorax pristodontus. It isn't as stout as I'm used to but I can't think of any other serrated cretaceous shark teeth you would find in Montana. The incompleteness probably accounts for it appearing more narrow too.
