GALVESTON, Texas, March 11 (UPI) -- A submarine expedition to the floor of the Gulf of Mexico has returned with "promising" clues regarding an ancient undersea shoreline there.
Anthropologist David Robinson told the Houston Chronicle that the expedition at the Flower Garden Banks National Marine Sanctuary yielded some significant data, yet was hesitant to say the area was 20,000 years old.
"We found an area that looks like a promising place to do further research," he said of the 6-mile-long studied area.
The study also marked the first use of some new vital undersea technology and the initial underwater search in the gulf for historical human life.
The 24 scientists involved in the expedition will now determine whether the discovered shoreline does indeed date back to the last Ice Age.
If the scientific group can make that determination, it will then attempt to gather any available evidence regarding human habitation in the area during that time period, the paper said.
