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 lasted from approximately 323 million to 298 million years ago, during the Paleozoic Era. It was characterized by the development of extensive coal forests and the diversification of early reptiles and amphibians.
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.
How long did the Ordovician period last?
The Ordovician period lasted approximately 41 million years, from about 485.4 million years ago to 443.8 million years ago.
What main things would travelers might see in the permian time period?
During the Permian period, travelers might see diverse marine life like corals, brachiopods, and ammonoids in the oceans. On land, they could have encountered early reptiles, amphibians, and primitive plants such as ferns and conifers. The Permian period also saw the existence of large insects like dragonflies.
When did Pangaea form?
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)
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 been around for 350 million years?
Cockroaches.
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?
500 million years of fish and proto-amphibians. -Melody Taylor (:
What happened 544-245 million years ago?
The Paleozoic Era began. Development of fish amphibians, insects and reptiles. Cambrian Period Ordovician period Silurian Period. Devonian Period Mississippian Period Pennsylvanian Period Permian Period
Was there amphibians before dinosaurs?
Yes, amphibians existed before dinosaurs. Amphibians first evolved around 370 million years ago, during the Devonian period, whereas dinosaurs appeared around 230 million years ago in the Mesozoic era.
