Fish and molluscs were the dominant creatures during the Devonian.
The first animal to walk on Earth was likely a type of primitive fish that developed four limbs and moved onto land around 360 million years ago during the Devonian period. These early tetrapods eventually evolved into the diverse array of land-dwelling animals we see today.
The same way you know you are who and what you are. They have evolved to do it just as all other living creatures do it. Why should fish be different?
Willow tree, a type of angiosperm
Trees were in the Devonian time period and they started from a small little plant and 500,000 years later they had turned into a HUGE forest.THE END!
The Rhynie Chert in Scotland is a Devonian age deposit containing fossils of both Zosterophyllophytes and Trimerophytes, the two major lines of vascular plants.
Espeon is one of the many evolved forms of EEVEE. It is a psychic type Pokemon that can be evolved from EEVEE with happiness during the day.(before 7pm just to be safe)
No, a stingray is a fish not a amphibian. They live in the oceans saltwater and there are many different species of them.
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.

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).

No one knows for sure. Some people believe that an asteroid earlier in time hit Earth and caused massive climate change that killed off reptiles, but spared dinosaurs. Others believe that it was simply climate change.
