Boney fish evolved and were able to grow legs and walk on land.
This is a cartilaginous fish there are 1100 species of them still around today.
Devonian period dawned about 416 million years ago
The Devonian period is part of the Paleozoic era
Devonian period is known as the age of fish
Ancestors of the Devonian period that are around today are the cartilaginous and the bony fish
Rugose coral went extinct at the end or near the end of the Permian period
The Devonian sea were dominated by brachiopods, tabulate and rugose corals which built large reefs in shallow water
Before this time period there was no organic accumulations in the soils, which resulted in the soil to be a reddish color.
At the start of the Devonian period, vegetation had began to spread
About 375 million years ago fish began to developed legs.
Tadpoles are around today and are known for developing legs and turning into frogs.
Ferns grew as large as trees
Plants did not have roots or leaves and some did not have vascular tissue.
Near the end of the Devonian period, larger and more complicated plants grew
Dry arid climate was a problem during the Devonian Period
Carbon dioxide levels were dropping on Earth
Average temperature of the water is 68 degrees Fahrenheit
Atmosphere was filled with oxygen
Carbon dioxide levels dropped which caused very dry and arid climate
The end of the Devonian period was unbearable to the point of extinction
The Devonian Period went on the number of species began to decay for aquatic life.
