Teeth?

[Camilynn]

I found these teeth, I think they are teeth at least, all in a row. They were found in Cowley county in Kansas. I know it was under shallow water for a long time but there was also something that looked curved like a canine. This was just a few of maybe 30 teeth all found in a row, top and bottom. Is it a shark, a wild animal, recent or are we talking a dinosaur? 
It's probably nothing but I figured you all would be the best place to ask! I've researched them for hours and am at a loss.

Sorry. These aren't teeth.

Sorry to disappoint you.

No enamel. No tooth morphology. This equals no teeth.

Vaguely triangular shaped rocks, unfortunately.

No disappointment here!  Thanks for your input!

@Camilynn Welcome to the hobby!  I agree that these aren't teeth, but there are many different types of fossils to be found in Kansas. 

 

This website may be a good place to start learning about the fossils in your area, and if you click on the links you can find several examples of what different Kansas fossils commonly look like:

I've included an example of shark teeth from Kansas below.  The shiny parts are the tooth enamel are one of the best characteristics to use when distinguishing between teeth and suggestively shaped rocks.
