Fossil records indicate the first gymnosperms (progymnosperms) most likely originated in the Paleozoic era, during the middle Devonian period: about 390 million years ago.Jurassic Period - Climate, Flora, Fauna: Jurassic climates can be reconstructed from the analyses of fossil and sediment distribution and from geochemical analyses. Fossils of warm-adapted plants are found up to 60° N and 60° S paleolatitude, suggesting an expanded tropical zone. In higher paleolatitudes, ferns and other frost-sensitive plants indicate that there was a less severe ...

Cambrian Case Index Geologic Time Scale. The Cambrian* Period begins the Phanerozoic Eon, the last 542 million years during which fossils with hard parts have existed.

Marine animals with mineralized skeletons make their first appearance in the shallow seas of the Cambrian, though ...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 Paleozoic Era (539–252 Ma) is in the Phanerozoic Eon, occurring after the Neoproterozoic Era, and before the Mesozoic Era. It is a time for great plant innovation and evolution. During this time land plants evolve and emerge from water, begin as lowly moss-sized plants, and become towering trees by the end of the Devonian Period. Paleozoic Era, major interval of geologic time that began 538.8 million years ago with the Cambrian explosion, an extraordinary diversification of marine animals, and ended about 252 million years ago with the end-Permian extinction, the greatest extinction event in Earth history.8.6: Paleozoic. Figure 8.6.1 8.6. 1: The trilobites had a hard exoskeleton and were an early arthropod, the same group that includes modern insects, crustaceans, and arachnids. The Phanerozoic eon is the most recent eon and represents time in which fossils are common, 541 million years ago to today.

Geologists have produced a new timeline of Earth's Paleozoic climate changes. The record shows ancient temperature variations coinciding with shifts in planet's biodiversity. The temperature of a ...What plants were on Earth during the Ordovician Period? The first land plants appeared. They were similar to mosses and other plants without deep roots or leaves. What was Virginia like during the Ordovician Period? Near the end of this period, North America and northern Europe collided, forming the Taconic Mountains north of Virginia. Cenozoic (66 million years ago until today) means ‘recent life.’ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era. Cenozoic signposts are colored yellow. ….

The climate was warming throughout Permian times, and, by the end of the period, hot and dry conditions were so extensive that they caused a crisis in Permian marine and terrestrial life.
