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.

How long did the pennsylvanian period last?
The Pennsylvanian Period was from about 325 million to 280 million years ago. It is part of the Paleozoic Era. The Pennsylvanian and the Mississippian (345 to 325 MYA) are often grouped together as the Carboniferous Period.
How long did the Ordovician period last?
The Ordovician lasted for 47 million years from 490 to 443 Million Years Ago.
What era and what period occurred during 418 to 355 million years ago and describe what was present during this time frame?
The era from 418 to 355 million years ago was the Paleozoic Era that existed during the Middle of the Silurian Period and at the end of the Devonian Period. Jawed fish, Arachnids, Eurypterids, Land Plants, Devonian Forests, Sharks, Lung Fish, and Bony Fish were present during this time frame.
What is carboniferous?
The Carboniferous is a geologic period lasting from about 358.9 million to 298.9 million years ago. It was characterized by the widespread formation of coal deposits, giving rise to its name. The Carboniferous also saw the first appearance of terrestrial vertebrates and the diversification of early amphibians.
Which era is the Devonian era?
The Devonian era is a geological period that occurred approximately 419 million to 359 million years ago. It is known for the diversification of marine life, including the appearance of early fish and amphibians, as well as the spread of forests on land.
Have amphibians been around for 255 million years?
Yes, but for longer than 255 million years. The earliest amphibians evolved in the Devonian Period about 370 million years ago.
Approximately how many million years ago did the earliest amphibians appear?
The earliest amphibians appeared approximately 250 million years ago.
When fish first walked?
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.
When did the first amphibians appear?
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!
What insects have the longest lifespans?
The poopstain lives for a million years.
How long have amphibians been on earth?
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.
What is the age of fishes and 1st amphibians?
The Permian period (280 to 248 million years ago) is known as the "The Age of Amphibians," because during the Permian, amphibians were abundant. I really didn't see anything as far as when the very first amphibians appeared. I would think they became dominant on land very quickly since they were the first land animals and had very little competition for food.
When was the first amphibian?
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.
What year was the first fish found?

Was there amphibians before dinosaurs?
Yes, the first ammonites lived during the Devonian Period. This was about 370 million years ago. The Devonian Period was a part of the Paleozoic Era.Dinosaurs did not appear until the Triassic, approximately 230 million years ago.HTH,Dr. C.
How long have amphibians lived on earth?
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.
