A school field trip. A pit filled to the brim with fossils. A valuable shark tooth over a million years old. And one bad boy who doesn't know better than to steal from mother nature.Modern-day sharks only live in the ocean, but Professor Igor proves that prehistoric shark bones can be found anywhere. And where there's bones, razor-sharp teeth aren't far behind . . . This series of hi-lo books is sure to sink its teeth into any reluctant reader--and refuse to let go until the final page.
