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.

Horsetails are another group of plants that are generally small today (up to 6 feet [1.8 m]), but during the Pennsylvanian, they reached heights up to 30 feet (9 m). Ferns were the third major non-seed plant group. Ferns are generally understory plants today, though in some tropical areas they can reach tree size.Carboniferous period (Paleozoic era): Fossil evidence indicates that the Carboniferous Earth was covered in green: the land was dominated by trees and forests including both seedless and seed-bearing plants.

Fossil plants found in areas located in high latitudes during the Carboniferous exhibit ...The periods that followed the Cambrian during the Paleozoic Era are marked by further animal evolution and the emergence of many new orders, families, and species. As animal phyla continued to diversify, new species adapted to new ecological niches. During the Ordovician period, which followed the Cambrian period, plant life first appeared on land.

For the Paleozoic era ... The development of simple plant life in the ocean was critical to the formation of an atmosphere that contained oxygen. Starting about 2.4 billion years ago, oxygen was released from the seas as a by-product of photosynthesis by cyanobacteria (Figure 1). Oxygen levels slowly rose, reaching the current level by about ...

The oldest animals on Earth appeared just before the start of this era in the Ediacaran Period, but scientists had not yet discovered them when the geologic timescale was made. Life was primitive during the Paleozoic and included many invertebrates (animals without backbones) and the earliest fish and amphibians.

During the 50 million year span of the Devonian period, all the major types of fish are present in the fossil record: ostracoderms, placoderms, cartilaginous fish, and bony fish. Placoderms Placoderm fish flourished in the middle to late Paleozoic but do not have any living ancestors today; by the end of the Devonian period they were extinct.
