During the Devonian Period the pectoral and pelvic fins of lobe-finned fish evolved into legs as they started to walk on and as tetrapods around 397ma Various terrestrial arthropods also became well-established.
The first seed bearning trees spread across dry land, forming huge forests. In the oceans , primitive sharks became more numerous than in the silurian and the late ordovician , and the first ray finned and lobe finned bony fish evolved. The first ammonite mollusks appeared, and trilobite the mollusc-like brachiopods, as well as great coral reefs were still common. The late devonian extinction severely affected marine life.

∙ 14y agoThe were definitely no humans in the Devonian Period.
The Devonian Period lasted from 416 to 359 million years ago.
Homo sapien or modern human did not evolve until 200 thousand years ago in the Pleistocene Epoch of the Quaternary Period, some 358.8 million years after the Devonian ended.
They are the only living example of the genus Homo in which the earliest members evolved 2.8 million years ago during the Pliocene Epoch of the Neogene Period.
Modern humans are also in the family Hominidae which also includes all the great apes and some lesser apes. The earliest examples of Hominids date back to about 20 million years ago in the Miocene Epoch of the Neogene Period.
In turn we belong to the order of primates which were thought to have evolved close to the end of the Cretaceous Period or the start of the Paleogene Period about 66 to 65 million years ago.
Even the family Mammalia of which we belong did not evolve until the late Triassic Period about 200 million years ago. This was still some 159 million years after the end of the Devonian.
Mammals evolved from the Reptilian Synapsida Subclass. They themselves did not evolve until the Carboniferous Period about 309 million years ago, some 50 million years after the Devonian.
There were not even reptiles during the Devonian. Reptiles were thought to have evolved from amphibians during the Carboniferous Period about 320 million years ago.
During the Devonian our only ancestors alive were the amphibians.

What period in the paleozoic era was the age of fishes?
The Devonian is known as the Age of Fishes.
The middle paleozoic era is known as?
The middle Paleozoic era is known as the Devonian period. The period ended with the death of many species of vertebrate life. During this time, many life forms transitioned from living in the water to living on land.
How long ago was the Devonian Period?
The Devonian Period lasted from about 395 to 345 million years ago. It is part of the Paleozoic Era.
Is the mississippian period in paleozoic era?
Yes. The Mississippian period is a part of the Paleozoic era, along with the Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, and Permian periods.
During Which age did humans learn domesticate plants and animals?
I believe sometime in the New Stone Age humans had learned to tame and breed animals for their own use.
Which era is the Devonian era?
the PALEOZOIC era
During what era did humans evolve from?
Cenozoic era

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.
During what period did the first vertebrates appear?
The first vertebrates evolved during the Cambrian Explosion about 525 million years ago. The Cambrian Explosion, obviously, occurred during the Cambrian period. The Cambrian period was part of the Paleozoic era.
Why wasn't there science during the dinosaur era?
there were no humans
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.
Humans are thought to have evolved during the what era?
The Cenozoic or "recent life" era
Are amphibians from the Jurassic era?
No. Although there were amphibians the Jurassic, they first appeared in the Devonian.
What period in the paleozoic era was the age of fishes?
The Devonian is known as the Age of Fishes.
What period did animals first begin to invade the land?
If you mean animals as in insects (arthropods), they came in around the Devonian period of the Paleozoic era If you mean animals as in fish, amphibians etc then they came in at the same time as the arthropods
