And I've done some field work at the old Norse site at L'Anse aux
Meadows, Newfoundland. They got around.
Sure did. And the Vikings didn't have to worry about big crocodilians that
far north.
(They didn't get as far as Australia though - despite assertions by certain
folks of questionable sanity.)
Interestingly, the presence of medieval Norse settlers on this side of the
pond has spawned a nefarious industry in fake North American Viking
artifacts. What a relief paleontology is free of such charlatans. Oh, hang
on...
