The Permian period was about 280 to 248 million years ago. The dominant organisms in this time period were the amphibians because they were abundant. However, there were other organisms, such as synapsids, fish and invertebrates.
The Cambrian Period (542 - 488 Ma)
The start of the Cambrian was marked with the extinction of the first multi celled animals. This period saw the rise of invertebrate arthropods. Ammonites and giant scorpions such as Giganatis came to dominate Earth. This was also the period fish 1st evolved but they lived securely in the shadow of the more dominant arthropods. This period also was the 1st animals to walk on the land. Evidence from tracks left by arthropods show that they at times left the water to walk on the land.
The dominant marine/aquatic animals during the Devonian included the placoderm fishes, and important marine invertebrates included trilobites, nautiloids and the first ammonites. The first land animals were arthropods, including scorpions, spider-like and mite-like arachnids, primitive insects, and myriapods.
Fish, in fact it has been referred to as "The Age of Fish" (I know that sounds goofy but its true)
many other organisms evolved too like land plants and the first amphibians

free-living! We don't live on or in other organisms.
All living organisms on Earth use DNA as their genetic material.All living organisms use cellular metabolism to obtain and use energy.All living organisms have some form of response to external stimuli.All living organisms undergo reproduction.All living organisms are made up of one or more cells, the basic unit of life.

The thing that is characterized by interaction of living organisms and climatic factors is called the ecosystem. The ecosystem contains all the living organisms and their abiotic factors.
Living organisms depend on other living organisms as food sources. AN overpopulation of a certain living organism or a decrease in a population of an organisms may unstable the other organisms that depend on it for food.

dimetrodon and edaphosaurus
Metazoans were abundant during the Vendian Period.
The living organisms that are dominant in a particular ecosystem depends on the ecosystem. In the rainforest for example, plants are the dominant organisms. In the desert, the animals are the dominant organisms.

dinosaurs
dimetrodon was the dominANT SPECIES OF THE permian period
The dominant organisms living at the Cretaceous period or time were first primates and flowering plants. This was the time when the extinction of the dinosaurs took place.
