Cambrian


The Cambrian period was the first period of the Paleozoic era. Following on from the Pre-Cambrian, it lasted from approximately 543 million years to about 490 million years ago. It was followed by the Ordovician period. The Cambrian was named by the geologist Adam Sedgwick for Cambria,[1] Latin for Wales, which has large areas of rock originating in, and characteristic of, the period.

The Cambrian Radiation gave rise to almost all living phyla, but often in extinct forms with small resemblance to typical living species. Common Cambrian fossils are of trilobites, and inarticulate brachiopods,[2] corals and primitive echinoderms. They also include the first vertebrates, primitive jawless fish.

Since many of the organisms of the Cambrian were soft-bodied invertebrates, fossil remains other than shells or carapaces are rare; one notable site for soft-bodied Cambrian invertebrate remains is the Burgess Shale of British Columbia.[3]

Young earth creationist scientists view

Young earth creationist scientists believe that the evolutionary geological timescale is in error. [4][5][6] These scientists believe that the earth is young and has multiple lines of evidence from the field of geology showing that the earth is young. [7][8][9][10][11] Also, young earth creationist scientists assert that there is an abundance of scientific arguments in addition to geology showing the earth and universe are both approximately 6,000 years in age.[12][13][14] In addition, young earth creationist scientists have a number of arguments against the position of an extremely old age for the earth and the universe.[15][16][17][18] Flood geologists also point out that catastrophism is increasingly being accepted in the field of geology. [19] [20] In addition, creationists also assert that old earth uniformitarian geology has numerous anomalies. For example, creationists cite the work of William R. Corliss who catalogued numerous anomalies in the old earth uniformatarian geology paradigm. [21][22] Corliss wrote regarding paraconformities the following:


“

"Potentially more important to geological thinking are those unconformities that signal large chunks of geological history are missing, even though the strata on either side of the unconformity are perfectly parallel and show no evidence of erosion. Did millions of years fly by with no discernible effect? A possible though controversial inference is that our geological clocks and stratigraphic concepts need working on." William R. Corliss, Unknown Earth (Glen Arm, Maryland: The Sourcebook Project, 1980), p. 219. [23]

”

The science journal New Scientist wrote regarding Corliss's work the following: "All I can say to Corliss is carry on cataloging." [24] Young earth creationist scientists assert that paraconformaties pose a serious challenge to the old earth uniformitarian geology paradigm. [25][26][27]
