The abundance and diversity of plant fossils increase into the Silurian Period, and by the middle Devonian Period, the heterosporous life cycle, which allows for more rapid evolution, had occurred independently in several groups, including lycophytes and the ancestors of ... The Paleozoic Era began with the Cambrian explosion. It ended with the Permian extinction. During the era, invertebrate animals diversified in the oceans. Plants, amphibians, and reptiles also moved to the land.The Mesozoic Era is literally the era of “middle life.”. It is also known as the age of dinosaurs. It lasted from 245 to 65 million years ago and is divided into the three periods described in Figure below. The Mesozoic began with the supercontinent Pangaea. Then, during the era, Pangaea broke up and the continents drifted apart.During the Paleozoic Era, evolutionary innovation moved onto land, as plants and, ... C. K. Boyce, A. H.

Early plants were small, unicellular or filamentous, with simple branching. The identification of plant fossils in Cambrian strata is an uncertain area in the evolutionary history of plants because of the small and soft-bodied nature of these plants.Feb 23, 2022 - Devonian Forest Plants middle of the Paleozoic era, 320 million years ago, mid to late 20th century. Painting by Charles R. Knight.During the Paleozoic Era, which lasted 289 million years, plants and reptiles began moving from the sea to the land. The era has been divided into six periods: Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian. Several times during this era, seas appeared and disappeared in Kansas.The fossil record spans 3 billion years of Earth's 4.6 billion year age. Similar to present day stromatolites, the first fossils were simple, anaerobic algal plants. The most common fossils are from organisms that had hard parts like shells and bones.
