Fossil ID- Teeth?

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.

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).

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.
