Introduction. The Paleozoic Era was a major interval of geologic time. It began 541 million years ago with a rapid expansion of life-forms and ended 252 million years ago with the largest mass extinction in Earth’s history. The Paleozoic was the first of the three major eras of the Phanerozoic Eon; this is reflected in its name: paleozoic is ... The Ordovician-Silurian Mass Extinction, explained in this World Atlas article, occurred about 443 Ma and killed 80-85% of the animals living on Earth, likely due to climate change. This extinction actually occurred in two major waves. The first started when the climate was cooling in 443 Ma, and the second wave began when the climate began to ...Liverworts Definition. Liverworts, like the species seen above, represent a branch of non-vascular plants, most of which are terrestrial. The name “liverworts” is derived from the belief in ancient times that the diseases of the liver could be cured with these plants. Liverworts are part of the kingdom Plantae, in the division Marchantiophyta.In the Mesoproterozoic Era, England and Scotland lay on different continents. Mudstones, sandstones and volcanic sediments were deposited in shallow seas. Multicellular life developed. The Palaeoproterozoic and Archaean cover a very long period of geological time during which the Earth’s crust and atmosphere were developing.Three tests based on fossil data indicate that high rates of extinction recorded in the penultimate (Guadalupian) stage of the Paleozoic era are not artifacts of a poor fossil record. Instead, they represent an abrupt mass extinction that was one of the largest to occur in the past half billion years. The final mass extinction of the era, which ...
