2: The Cambrian period is the first geological period of the Paleozoic era. It lasted from 541 to 485 million years ago. The Cambrian period had many types of animals the most common ones were metazoan, and adequate. The different types of animals were marrella, costata, etc. The Cambrian period also had many plants. All the plants in the Cambrian times were under water. Some plants in the Cambrian times were wapta,pikala,etc.The climate of the begging of the Cambrian times were very cold and humid. The temperature of the time was about 120 degrees Fahrenheit. The period began from 541 to 485 million years ago.it had many different types of animals and plants, which were all underwater. The climate of that time is 120 F.
3: The Cambrian times had many plants some of which were cell algae, bacteria, and plankton. Most species of animals and plants evolve during the Cambrian times. An example of this is the body parts of an animal that lived in the Cambrian times match the body parts of a small modern animal. The Cambrian times had a lot of plants. Some different types of plants are margaretia and dorus, which came from burgess shale. Some of the more common plants in the Cambrian era were wapta, british Columbia, chordade, pikala, and Canada. All plant life lived in the oceans and seas. There were no plants to keep the soils in place there by impacting both climate and geography. The Cambrian times had many plants some were algae, bacteria, and plankton. Some varieties were wapta, british Columbia, pikaia, and etc.
4: he first animals that appeared in cambrain times were metazoan, and adequate. Some different types were kimerella, dickinsonia costata, and marrella. All of the animals in cambrain times were aquatic animals. Many animals had unusual body layouts,buts some members of the animals and still around today. One type of Cambrian animals that are still around today is a arthropods. A common type of animal is a sanctacaris, which grew to nine cm and made a living by swimming around and eating prey with its spiny mouth. The animal was called santa coris because of these formidable claws. Its original name sancta coris translates to holy shrimp. The first types of life forms in Cambrian times were metazoan, and adequate which were all animals that lived underwater.
5: The climate at the beginning of this period was cold. Over time the climate in all parts of the earth grew warmer and humid. This made the seas a good place for many species to live. In the Cambrian times 85% of the earth was water unlike today 70% is made of water. This made the temperature about 120 degrees Fahrenheit.Althoght it was cold and humid sand dunes were in most areas above sea level. The emerge of land plants came later. The beginning of the Cambrian period was very humid and cold.
