What happened during the paleozoic era.
Paleozoic Era. From an explosion of early life to the greatest extinction in history, the Paleozoic was a time of change. During this earliest era, living things developed vertebral columns and hard body parts like jaws, bones and teeth. Fish evolved, and plants and animals started the move from the ocean onto dry land.

It began 485.4 million years ago and ended 443.8 million years ago. The interval was a time of intense diversification (an increase in the number of species) of marine animal life in what became known as the Ordovician radiation. Research from the University of Copenhagen suggested that at the end of the last ice age a change in the grasses resulted in their decline. These grasses changed from what was called C-3 to C-4 grasses, which contain more silica and were far less nutritious. Thus, the animals were not getting the right type of food.Jul 7, 2022 · What events happened during the Paleozoic Era?

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 ...The Paleozoic Era, which ran from about 542 million years ago to 251 million years ago, was a time of great change on Earth.
