+ D Page view | A Read aloud Draw 9. A limestone unit contains the following guide fossils which have the given ranges in which they existed: A specific trilobite: Cambrian to Mississippian a specific nautiloid: Ordovician to Pennsylvanian a specfic brachiopod: Cambrian to Ordovician a specific graptolite: Ordovician to Silurian To find the age of the limestone, find the ONE period when those fossils were all there. Not the era, they are all from the Paleozoic era. Remember, words from the time scale are ages, don’t convert these periods to numbers. period: 10. In McKelligon Canyon, the 488-million-year-old Bliss Sandstone unconformable overlies the 1170-million-year-old Red Bluff Granite. How many years of erosion does this unconformity represent? If you did not know the numerical ages of the Bliss & Red Bluff, what evidence could you use to determine which was older? [Note-since the Red Bluff is an intrusive igneous rock, you can’t use its position under the Bliss.]
