Preserved in its original matrix, the specimen captures a moment on the ancient lakebed, offering a literal snapshot of life and death some 50 million years ago. The shoal of 5 partially intact Knightia show fine skeletal detail and subtle scale impressions visible, and the partial smaller fish remains and fragments provide additional context of a natural mortality assemblage. \u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eAdding to the ecological narrative, a sunning three-dimensional gastropod with a distinct white calcified tip is preserved in situ alongside the fish.
