What was the Cambrian Period?
How did it happen? Your questions will be answered… The Cambrian Period offically kicked off the Paleazoic Era, during which many new species of animals evolved. So many new cretures appeared, almost simantainously, that this event was named the Cambrian Explosion. The Cambrian Period was the time of Gondwanaland and Lauraisa. We know this because Alfred Wegener proposed the theory of Continental Drift. He developed this theory to explay why the continents fit together like puzzle pieces and had similar fossils. This theroy proposed that at one point in time, even before the Cambrian Period, the conteniets were all joined together in one great super conteniet called Pangaea. Many animals appeared in this time period. Man is still finding fossils of trilobites, prehistoric worms, Brachiopoda, and many pre-evolved forms of starfish, sea urchins, and star brittles that exhisted during this time period. The Cambrian Period, a timeless wonder of revolution and prehistory. Amazing that the
The Cambrian period is a major division of geological time, extending from about 542 to 488 million years ago. It is the first period in the broader Paleozoic era. The Cambrian is characterized by the appearance of a wide range of complex, fossilizable multicellular organisms. Prior to this, multicellular organisms were more like simple colonies (sponges and medusoids) rather than differentiated animals. In a period lasting about 10-20 million years during the beginning of the Cambrian period was an event called the Cambrian explosion, referring to the sudden emergence of numerous well-preserved animal fossils. During the Cambrian explosion, all the major body types emerged. The Cambrian periodis named after Cambria, an older name for Wales, where Cambrian-era fossils were first found. The time prior to the Cambrian period is referred to as the Precambrian. For a long time it was thought that the Cambrian period signaled the emergence of multicellular fossils in general, but discoverie
