Isurus hastalis
Fossil shark teeth collected at an undisclosed location along the Potomac River, Westmoreland County, Virginia USA. Note: The quarters used to show the relative size of the fossil specimens are approximately one inch (~1") in diameter. Photo 1 of 2: Lingual side, shown facing up; labial side, facing down. Photo 2 of 2: Labial side, shown facing up; lingual side, facing down. Two fossil shark teeth collected at the same location; two different colors. The color of a fossil shark tooth is often caused by chemicals that replace elements in the original specimen. For example, phosphate replacement can cause fossil shark teeth to be black in color.
A relatively "shallow" sea that existed along the east coast of the United States an estimated 10- to 15 million years ago, during the Miocene Epoch. Related Resource: Miocene Marine Life http://paleobiology.si.edu/geotime/main/...

You're absolutely right!
Found, of course. In my opinion, the real value of a fossil specimen is the thrill of finding it!
Found or bought?
