Erik, I beg to differ on the No stone artifacts were found in Newfoundland. I Can't remember where I saw it, but it could have been the history channel, science channel, national geographic, etc. but one of them showed a couple of spear blades, and a knife blade made out of Nephrite, a type of jade, which is extremely hard, and durable. The blades were in the Viking styles, and were ground and highly polished. No, I am not an expert. I don't believe I have stated so. Are you? I didn't mean to step on your tail.
I have seen this article a few years back. And they were found in the Viking ruins in Newfoundland. Whether these blades were used as weapons, or not, I don't know. But to go to all that trouble to grind a chunk of nephrite, and shape it, and polish it, I would think it would be used. Nephrite is extremely hard stuff. It is found in Newfoundland, and Canada. How the blades were ground and shaped I have no idea. But they were found among other artifacts. As to how I know it was a Viking skull, I am taking the word of Claude Van Order, who was at the museum in Denmark, and it was listed as a viking skull. So I wasn't in on the archaeological dig, and have no idea of how the museum, knows it was a viking. I will take their word till it is disproved by some other archaeologist down the road, with newer techniques, and scientific information.
I am sure the museum can explain how they know it was a viking skull. If I ever hit the power ball, I will personally go there and ask them. Hell, I will even take you along also. They can answer a lot of questions. Do you speak Danish? That would be a big plus.
