- Comments
- BbGc-VP, Hemlock Park: Horse bones recovered from what appeared to be glacial outwash were expected to yield a late Pleistocene age. The structure of the teeth suggested a fossil horse. However, the resulting collagen date neither matches that expectation nor provides a reasonable age for a horse that could have been introduced during the historic period. As Krueger notes in the date list, collagen is "far superior" to carbonate in cases of discordance. This date may represent an exception to that rule.
