"Named Galagadon nordquistae, the newly-discovered shark species ....of what is now South Dakota.
It was a small freshwater shark (12 to 18 inches, or 30.5-45.7 cm, long), related to modern-day carpet sharks such as the ‘whiskered’ wobbegong shark.
Its tiny teeth — each one measuring less than a millimeter across — were discovered in the sediment left behind when paleontologists uncovered the bones of ‘Sue,’ currently the most complete T. rex specimen ever described.
“It amazes me that we can find microscopic shark teeth sitting right beside the bones of the largest predators of all time. These teeth are the size of a sand grain. Without a microscope you’d just throw them away.” Dr. Gates added.
“There is no way for us to understand what changed in the ecosystem during the time of the mass extinction at the end of the Cretaceous without knowing all the wonderful species that existed before.”

Time of the "mass extinction"....the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. (Gen.7:11) this would explain the shark teeth scattered across South Dakota.
