I suggest you type the species name and the words "for sale" into a search engine (e.g. Google, Bing, E-Bay) and see what sites/fossils display.

Just a quick attempt on my part shows a site in the U.K. listing teeth like this for £8-20. Checking the exchange rate at shows a £1 = $1.50 so $12-30.

Of course, this is an asking price, it would be better to find it on E-bay on a list of sold items to see what was actually paid for one of these fossils.

I hope you have found a fossil treasure.
