Distinguish between the oldest and youngest portion of a geological section using principles of superposition, original horizontality, lateral continuity, and cross cutting relationships: biostratigraphy. Describe the concept of faunal succession and the use of fossils in correlation and in the subdivision of earth history. Recognize the qualities that make fossils useful in biostratigraphy. Thin layer of life on earth"s surface. Life is very inter-connected, and spans over multiple ecosystems. Things were a lot more different then the biosphere evolved a lot. Cretaceous ocean: around 130 million years ago. Stratigraphy and biostratigraphy tools of the trade for studying the past. Biosphere composed of indiv. species that have evolved thru time. Knowing this can help our understanding of the passage of time on earth. Passage of time recorded in rock layers.
