ARCHAEOLOGY: Sharks in Arkansas & Oklahoma?

In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. Genesis 7:11

"The newly-described species lived in the Devonian oceans.
Named Cosmoselachus mehlingi, it is one of many well-preserved fossil sharks from the oil-bearing Fayetteville Shale Formation, which stretches from southeastern Oklahoma into northwestern Arkansas and has long been studied for its well-preserved

invertebrate and plant fossils.
Dr. Bronson and colleagues CT-scanned and digitally reconstructed the specimen.
They worked for many months to describe its anatomy, including dozens of tiny pieces of cartilage.
Once the reconstruction was complete, they placed Cosmoselachus mehlingi in the tree of life of early cartilaginous fishes."
