St. Mary's College dean of science Judd Case and his colleague James Martin say the 2-millimeter fossil, which belongs to a newly discovered, extinct species similar to an opossum, suggests that dinosaurs and small marsupials not only lived in Europe at the same time, but also traveled the same trans-Atlantic migration route from South Dakota to the Netherlands.
"Wow," said Case. "It changes what we know."
