The most popular color? We’ve all noticed the many layers of rock strata as we drive along a road cut. It seems as though we are driving through a huge “layer cake,” cut open to expose the inside. Grand Canyon looks this way. Most of the exposed layered rocks are sedimentary rocks. Geologists tend to use the term 'rock strata' in a generic sense when referring to many rock layers that appear over large areas.

Although the practice of mapping geologic layers had begun in the mid-17th century, the science of how strata formed was still nascent. Figure \(\PageIndex{1}\): Geologic Time Scale with ages shown in millions of years ago (Ma).

Conterminous US. Much supposed geological time missing from strata. by Michael Oard For many years, Ager pointed out that there was an enormous amount of time missing from the strata relative to the long geological time assigned to the strata by geological dating methods. 1,2 In other words, there are many more gaps than record.

They are very common features of the geologic record. The Paleozoic Strata contain many fossils that help scientists learn about the geologic history of North America. Most of the fossils are ocean-dwelling creatures, telling us that the area now in the middle of Arizona was once a sea. Some of the most common fossils found in the Grand Canyon are listed below.

Although the practice of mapping geologic layers had begun in the mid-17th century, the science of how strata formed was still nascent. Instead, the evidence points to the whole 1,200-m (4,000-ft) thickness of strata being still ‘plastic’ when it was uplifted.

But the that distinct rock strata represented different periods of time in Earth's history.
