During the Devonian Period the pectoral and pelvic fins of lobe-finned fish evolved into legs as they started to walk on and as tetrapods around 397ma Various terrestrial arthropods also became well-established.
The first seed bearning trees spread across dry land, forming huge forests. In the oceans , primitive sharks became more numerous than in the silurian and the late ordovician , and the first ray finned and lobe finned bony fish evolved. The first ammonite mollusks appeared, and trilobite the mollusc-like brachiopods, as well as great coral reefs were still common. The late devonian extinction severely affected marine life.
