Index fossils delineate the epochs of geologic time. In order for an organism to be considered as an index fossil it must possess at least one of the four characteristics: it must be unique, extensive, abundant and inadequate in geologic time. Most type of organism may be considered distinctive but not widespread which tolerate them to inhabit all over the world. While some are considered abundant that they were able to be developed as the most susceptible to environmental modification and destruction. Just like the trilobites, this is known as a precise example of index fossil for the Paleozoic rocks that is inhabit in all parts of the ocean. They develop new species throughout their being, which is according to some reports, lasted 270 million years from Middle Cambrian time to the termination of the Permian Period. Because of their ability to travel, they tend to dwell in global areas. The trilobites are huge that they can be used in a study even without a microscope and they are also hard-shelled invertebrates which make them petrified effortlessly.

How does archbishop usshers work compare to that of james hutton
Nataly_w [17]

<span>James Ussher was a creative scholar, a church leader and became famous for his genuine letters of the church. He is the Archbishop of all Ireland and majorly impacted Reformation theology.  He is best known for his chronology research that concluded Adam was created in 4004 B.C. In reality, Ussher was a first-class scholar very involved in scholarly research. He regularly interacted with “the most learned men of the day” to intellectually savor their ideas. He was also “a real connoisseur of books,” and there was scarcely a book in any British library that he was unfamiliar with. While James Hutton is known as the Father of Modern Geology, Hutton is a Scottish Geologist and a naturalist who originated the concept of earth’s crust during geological history, which explains the features of the Earth's crust by means of natural processes over geologic time.  Hutton had formulated controversial theories of the origin of the earth and of atmospheric changes known as 'uniformitarian’s'. This paved the way for modern geological science.</span>
