Scene from an ancient sea floor, as if it happened yesterday, however, these are from Permian period
Scene from an ancient sea floor, as if it happened yesterday, however, these are from Permian period (~299–251 million years ago). Some of these fossilized bivalve shells are still articulated, meaning, left and right shells are still closed together. This tells you that particular animal specimen was undisturbed since its death, until now. The hard rock that envelops these shells was once a soft sediment in which these molluscs lived.South coast NSW, Australia -- source link
