When they took the bone back to the lab they realized that the bone had only Dating and wondering put your first handle the phone. Finding an answer to that question will be discussed in subsequent sections.

The layers within the circled area have actually been inverted.
As will be seen, fossils frequently play a vital role in correlation. To demonstrate the equivalency in age of the shells and the bones may not be simple.

Diagram A illustrates an extensive outcrop of horizontal layers exposed over a great distance. Field learning provides a chance to encourage the ability to see features that are important to professional practice. Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. Paine discusses the dynamic nature of the Texas Gulf coast. Skill is needed to recognize such objects and to distinguish them from ordinary inclusions.
