We have been taught that each of the Earth's strata layers were deposited over millions of years. OK, if that's true we could never expect to see a tree trunk buried vertically extending through multiple strata layers, could we? But we do see them - all over the world. These are called polystrate trees. Fossils crossing two or more sedimentary layers (strata) are called poly-strate (many-strata) fossils.
