The Devonian Period lasted for about 63 milion years. It occurred 354-417 million years ago.
The Devonian period lasted from 416 million years ago to 359.2 million years ago.
The Devonian period is 419 200 000-358 900 000 years ago.
aprox 600 million years ago in cambarian period but the real period of fish is known as Devonian period which was 440 million years ago.
360 million years ago
Fish first appeared in the Cambrian period, long before the Devonian.
The Devonian is not a kind of fish. It was a period in Earth's history that lasted from 416 to 359 million years ago.
The Devonian Period, which is about 417 to 354 million years ago, is in the Paleozoic Era. The most common shell fossils from the Devonian Period are those of Brachiopods, whose shells are symmetrical but unequal in size. Today they are mostly extinct.
The period after the Devonian Period (416 to 359.2Ma) is the Carboniferous Period (359.2 to 299Ma).
That was the beginning of the Devonian peroid and the end of the Silurian period. It was that period when the first insects came to Earth.
The 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.
The seed came from 385 million years ago during the Devonian period.
The first trees appeared about 360 million years ago in the Devonian Period.
During the devonian period (435-410 million years ago) of the Paleozoic era , the fist plants and insects appeared on Earth.
Paleozoic era and middle of Silurian period-end of Devonian period ( . Y . )
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.
The Devonian is a geologic time period and system of the Paleozoic era spanning from 416 to 359 million years ago. It is named after rocks that were studied in Devon, England. It comes between the Silurian and the Cretaceous periods.
Devonian to cretaceous is the the geological age of ammonoids They first appeared during the Devonian Period (approximately 410 million years ago). They almost died out at the end of the Permian Period (251 million years ago), and again at the end of the Triassic Period (205 million years ago). They finally became extinct at the end of the Cretaceous Period (65 million years ago), perhaps as a result of a lowering of ocean levels.
The Devonian Period
The Devonian Period from 417 Million years ago to 354 Million years ago. The time period was known as the Age of Fishes because of the thousands of species of fish that developed in the sea.
Yes. Amphibians first appeared in the Devonian period, long before the Permian.
Around 400 million years ago, in the Devonian, the age of sharks and early amphibians.
The first terrestrial vertebrates (tetrapods) had evolved by the middle of the Devonian period, about 385 million years ago.
