英语百科
Bone bedA bone bed is any geological stratum or deposit that contains bones of whatever kind. Inevitably, such deposits are sedimentary in nature. Not a formal term, it tends to be used more to describe especially dense collections. It is also applied to brecciated and stalagmitic deposits on the floor of caves, which frequently contain osseous remains. |
