What animal vertebrae?

[Masquay]

My husband found this on the river, brought it home to me cuz I collect masks and he thought it looked like a mask....thats why the first picture has google eyes placed in it! What animal would this have come from?

I think you have a cow atlas.

Thanks again Harry, is there a way to get an approximate age on this item also??
