the carboniferous period had crinoids,echinoderms but today we don't have it
During the Carboniferous period, the environment was warm and humid, with vast swamp forests covering much of the land. These forests eventually formed the coal deposits we see today. In contrast, the present environment is cooler and drier overall, with different vegetation and ecosystems in place.
grassy and naked
it was different then the presant and there was so many thing thst we dont have now
all of the land was under water and the world was all messy
Basic plants and flowers start to grow, the land is mostly covered with tree's, and new found grass.
During the Precambrian period, which lasted from about 4.6 billion years ago to 541 million years ago, the Earth's environment was very different from the present. The atmosphere had little to no oxygen, the continents were still forming, and life was mostly single-celled organisms. The present environment is characterized by a more oxygen-rich atmosphere, complex multicellular life forms, and well-established continents.
The Quaternary Period experienced fluctuating climate with multiple ice ages and interglacial periods, resulting in extensive ice sheets and glaciers. In contrast, the present environment is characterized by a warmer climate with less extensive ice cover and higher sea levels. Human activity has significantly impacted the environment in the present, leading to issues such as global warming and biodiversity loss.
During the Jurassic period, the environment was warmer and had higher levels of carbon dioxide in the atmosphere compared to the present. The landmasses were generally located closer together, forming the supercontinent Pangaea. The Jurassic period had a diverse range of plant and animal species, including dinosaurs, which dominated the terrestrial ecosystems.
Alexis and Victoria said that it wuzz mostly ever so evergreens aned it wuzz lyk sooo moist. It didnt compare ta tha present right now becuz we have different kindz of climates.
it was mostly covered with trees and grass.
The first ancestors of mammals appeared in the Carboniferous period about 358.9 ± 0.4 million years ago. Before this time there were no mammal or mammal like creatures present to become fossilised.
The 2nd half's climate was during glaciation
