This time we know modern horses crossed the land bridge from North America to Asia. Other animals that crossed the land bridge were camels, lions, saber toothed cats, wooly mamoths, bison, armadillos, and mastodons.

The same land bridge was still open 10,500 years ago after stone aged hunters crossed over from Asia in statistcally significant numbers 11,000 years ago. We find their highly developed lithic projectile points, called Clovis Points, in association with Mamoth Kill Sites throughout North America. There is a marked concentration of these kill sites running North and South just East of the Rockies. Some mamoth bones have been found with Clovis points still embeded in them.
