Both insects and amphibians are thought to evolve during the Devonian Period.
The earliest known insect, Rhyniognatha hirsti, is thought to have evolved from arthropod ancestors around 400 million years ago during the Emsian age of the Lower Devonian Epoch.
The earliest known amphibian, Elginerpeton was thought to evolved from lung fish around 375 million years ago during the Frasnian age of the Upper Devonian. It is also thought to be the 1st tetrapod.
The Permian period was 230 to 280 million years ago. Travelers during this time period would have been able to witness the start of the Alps, the Appalachian, and the Rocky Mountains. There were many massive sand dunes throughout much of the United Kingdom and the United States that were transitioning into sandstone formations. Insects and amphibians were rich throughout the Carboniferous area.
The Ordovician lasted for 47 million years from 490 to 443 Million Years Ago.
Pangaea formed about 300 million years ago and began to rift about 200 million years ago.The formation and falling apart of super continents appears to be cyclical. Pangaea is the fourth super continent in Earth's history.Known super continents:Columbia (2 billion years to 1.8 billion years ago)Rodinia (1.1 billion years ago to 750 million years ago)Pannotia (600 million years ago to 540 million years ago)Pangea (300 million years ago to 200 million years ago)
The continents will not have changed noticeably in 20 million years.

Yes, but for longer than 255 million years. The earliest amphibians evolved in the Devonian Period about 370 million years ago.
The earliest amphibians appeared approximately 250 million years ago.
The first fish to develop legs and who mostly developed as the earliest amphibians, being able to live on and as well in water, came about around 370-400 million years ago.
6 billion years ago No, the Earth is only 4.6 billion years old. Amphibians appeared on Earth during the late Devonian period in the Paleozoic Era about 365 million years ago. Hope that helps!

Tetrapods (early amphibians) emerged in the fossil record some time int he lower Carboniferous, around 360 million years ago. Reptiles emerged later in the carboniferous, 320-310 million years ago, and were probably the dominant terrestrial fauna by the start of the Permian, 299 million years ago. If any period in geological history could be described as the age of the amphibians, it would be the lowere-to-middle Carboniferous.
360 million years ago, during the Devonian period. that's when the oldest amphibians were discovered. but the modern day amphibians were discovered 250 million years to 65 years ago, during Mesozoic Era.

Amphibians have existed on Earth for over 300 million years. They are one of the oldest vertebrate groups, with their ancestors dating back to the Devonian period.
