The Silurian

During the Silurian period, life would recover from the end-Ordovician mass extinction. The gradual warming of the Earth and the re-filling of the shallow seas would lead to a radiation of marine life. Meanwhile, plants would further establish themselves on land. During the first half of the period plants would diversify into distinct groups of seedless nonvascular plants and by the end of the period, the first vascular plants appear in the fossil record. Finally, during the Silurian, animals would appear on land for the first time in the form of terrestrial arthropods. In this video, That Bio Doc talks about what life was like during the Silurian Period, 443.8 - 419.2 million years ago.
