The Paleozoic era covers the time from the first appearance of abundant, hard-shelled fossils to the time when the continents were beginning to be dominated by large, relatively sophisticated reptiles and relatively modern plants.The era's lower (oldest) boundary was classically set at the first appearance of creatures known as trilobites and archeocyathids.Other places to find fossils are along Hinkson Creek or in Capen Park and Rockhill Park. For the nature-averse, urban fossil hunting is a serendipitous way to spot crinoids and bivalves. Emily Edwards, an MU teaching assistant and graduate student researching geology, says you can spot fossils in the limestone often used in buildings.

Therefore, their fossil remains can be used as an index or guide to that time, and consequently are called index fossils (Figures 7-2 and 7-3). For example, a marine animal called a trilobite lived only during the Paleozoic Era. Rocks containing trilobite fossils can be inferred to have been deposited during the Paleozoic.As much as 95% of the life on Earth died out at this time.

See more.Direct fossil preservation of leaf damage, arthropod mouthparts, and vertebrate teeth has understandably led to a focus on oral processing of plant material when considering the evolution of herbivory in deep time. Here, nutrient stoichiometry is advocated as an important alternative constraint on the evolution of herbivory. Most life possesses C:N ratios of approximately 7:1, but uniquely ...Mesozoic Fossils. The Colorado Plateau is a vast area that covers approximately 130,000 square miles of Utah, Arizona, Colorado, and New Mexico.
