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. Each book includes discussion and writing questions, a glossary, and educational back matter.
