The dominant organisms during the carboniferous time period were plants. They were large, vascular, land plants that sometimes grew to be one hundred feet or more.
Crinoids and ammonites were the dominant marine life forms during the Mississippian stage of the Carboniferous period.
Arthropods were at their largest during this period due to high oxygen levels. It´s sometimes called the Age of the Insects. Ferns and horsetails grew to the size and build of trees, too, and fossils of them are common.

During the Carboniferous period, dominant species included early amphibians, insects, and vast forests of primitive plants. This period is often referred to as the "Age of Amphibians" due to the diverse amphibian species that thrived in swampy environments.
it was the Crassigyrinus it was aguatic and had sharp teeth. == ==
During the Tertiary period, dominant organisms included early mammals, large birds, marine mammals like whales and dolphins, and diverse plant species. This period saw the rise of modern mammals, along with the evolution of grasslands, forests, and flowering plants. The Tertiary period also saw the decline of dinosaurs and the rise of more familiar animal groups.
Some dangers in the Carboniferous period included volcanic activity, which could lead to eruptions and the release of toxic gases. Additionally, the high levels of oxygen in the atmosphere during this time could have increased the risk of wildfires. Lastly, the presence of large predatory insects and amphibians could have posed a threat to other organisms.
Metazoans were abundant during the Vendian Period.
