Mr. Bjarni Herjolfsson, a Norwegian, set off to visit family in Greenland, but got off course. There were no maps, and his sense of smell was not good. Anyhow, rather than Greenland, he sailed up the coast of North America, as it turned out.

He turned back to find Greenland, never setting foot on his Big Discovery, the first European human sighting of this continent. He later sold his boat to Leif Erikson, who made a settlement in 1000AD.

Rhinos were not there, but We find the idea intriguing. Ahoy.
