What caused the Devonian Extinction?
Evidence leads most paleontologists to believe the Devonian mass extinction event to be caused by global cooling, triggered by a glaciation event on Godwana. A less-proven theory states the extinction could have also been caused by meteoric impact.Background Info:After the Ordovician mass extinction event around 440 - 450 million years ago, surviving groups of species continued to diversify evolutionarily into what became the Silurian and Devonian periods.The Devonian period spanned from 408-360 million years ago, in which came the first sharks, bony fish, and ammonoids (a type of predatory mollusk) in the ocean, as well as terrestrial amphibians, insects, and true land plants.
What types of water are fish found in?
Opinion on this varies, but generally the wet type is considered best for fish. There is some discussion about how wet the water needs to be, but as a general rule of thumb "The Wetter The Better" (as the water gets drier there is less of the wet that fish have evolved to utilise).
