Trilobite parts, I think. The one on the bottom is the first one that I found. When I saw it laying there, I felt as if I were in a dream. I honestly never thought I would stumble into a fossil bed containing trilobites. As I reached down to gently pick it up, I felt honored to touch this link to the distant past. I am reminded of the Pink Floyd lyric: "...the eccoes of a distant time come willowing across the sand. And everything is green and submarine....And no-one called us to the land and no-one knows the wheres or whys.But something stirs and something tries and starts to climb towards the light."
