"85,000,000 years ago Bering Strait" changed to "85,000,000 years ago the Bering Strait"

Original Paragraph:

^{P689:7, 60:3.8} 85,000,000 years ago Bering Strait closed, shutting off the cooling waters of the northern seas. Theretofore the marine life of the Atlantic-Gulf waters and that of the Pacific Ocean had differed greatly, owing to the temperature variations of these two bodies of water, which now became uniform.
