1: Devonian Period Information | The Devonian Period is known as the age of fish and the age of plants and trees. This is because fish started developing during this period. Also, the period marked the emergence of seeds, which made the reproduction of plants much easier. Many gigantic reefs were also built.
2: Archaeopteryx- the first species of tree. It emerged almost at the end of the period. | Eophyllophytonbellum- one of the first plants with leaves.
3: Plants During the Devonian Period | Ferns- some of the first plants that were 1 meter tall.
4: Animals in the Devonian Period | Dunkleosteus-Largest of all Placoderms | Osteichthyes-Bone Fish | Placoderms- armored fish extinct at the end of period
5: Chondricthyes- shark, one of the biggest predators
6: Carboniferous Period Information | The Carboniferous period is especially famous because Pangea was formed during this period. Also, the large numbers of carbon-bearing coal deposits gave the name to the period. One especially unique and attractive aspect of this period are the giant insects that came into being. If you are interesting in witnessing the earliest amphibians and reptiles, this is the period to visit! Also, because of the large amounts of oxygen in the air, organisms were much larger than they are now.
8: Plants during the Carboniferous Period | Ferns- looked much of the same as in the Devonian Period. Were up to 1 meter tall
9: Cycads- huge palm trees that bore seeds.
10: Tetrapods- this was the period in which many species of 4-legged animals appeared. | Meganeura- a dragonfly with a wingspan of 75 cm. | Arthropleura- a giant millipede that grew to 1.5 meters of length. It had 30 pairs of legs.
