Miocene Sharks Teeth of Calvert County
http://www.mgs.md.gov/esic/brochures/sharks.html

Fossil shark's teeth (about 17 million years old) can be found in sediments known to geologists as the Calvert Formation of early to middle Miocene age. Sharks teeth from the Calvert Formation are often well-preserved and sometimes quite large. This DNR Maryland Geological Survey web page provides information about the ancient sharks and other sea life of the Miocene and ideas about why sharks teeth are common in these sediments. (The National Science Teachers Association selected this web page for inclusion in their sciLINKS program.)
