Introduction
The Silurian was named for a Welsh tribe, the Silures, which lived in the area where Roderick Impey Murchison first described rocks of this age. Murchison studied the complex geology of western Wales in the 1830s and carefully documented the abundant fossils present in the Silurian strata.
Significant Silurian events
During the Silurian Period Earth underwent considerable changes, which had important repercussions for the environment and life. In particular, Earth’s atmosphere developed an effective ozone layer concentration. Generally speaking, the climate stabilized, ending the previous pattern of climatic fluctuations that periodically caused continental glaciations; glacial melting contributed to a substantial rise in global sea level.
Possibly the most remarkable biological event during the Silurian was the evolution and diversification of fish. Not only does this time period mark the wide and rapid spread of jawless fish, but also the appearances of both the first known freshwater fish and the first fish with jaws.
