The Ordovician period and the Silurian period
Paleozoic era and middle of Silurian period-end of Devonian period ( . Y . )
The Silurian period spans from 443 to 419 million years ago. The earliest dinosaurs evolved 231 million years ago. That means there were no dinosaurs at all during the Silurian.
Yes. The Mississippian period is a part of the Paleozoic era, along with the Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, and Permian periods.
The firsts insects appeared in the Silurian period( in the paleozoic era)
The Silurian is a geologic time period of the early Paleozoic. The Silurian was approximately 440 million years ago, to 416 million years ago. The Silurian was the period immediately after the Ordovician.
The Paleozoic Era
The end of the Silurian period and the beginning of the Devonian period was not defined by an extinction event, but by the distinctive rock formations of the period. As a result the end of the Silurian period is uncertain by +/- 2.8 million years.
The Devonian was the geological time period that followed the Silurian.
Land plants first appeared in the Silurian period. This period took place during the Paleozoic Era. This was 438 million years ago.
If you are asking what era the fish ORIGINATED, then your answer is the Cambrian Period, which was during the Paleozoic Era (544-245 million years ago). They started off as invertebrates, however. The first vertebrate that was a fish was the jawless fish in the Ordovician period. The first vertebrate that was a fish was the jawed fish in the Silurian period.
Millipedes evolved to be the first land animals. This took place in the Silurian geologic period which was part of the Paleozoic Era.
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
Fossils from the Silurian Period are between 443.7 and 416 million years old.
The Silurian period.
The Silurian Period started 443 million years ago and ended and 417 million years ago.
The Silurian went from 443.4 Â± 1.5mya to 419.2 Â± 3.2mya. It spanned from the conclusion of the Ordovician period to the beginning of the Devonian period. However the exact time frame of the Silurian period is unknown and could be off by millions of years because of the fact that that period was set during a significant extinction event. Therefore, the Silurian period lasted about 42 million years, give or take.
Plants during the Silurian period are of the genus Cooksonia. It was a branching stemmed plant that produced sporangia on their tips.
The Ordovician-Silurian extinction as well as many new species
It was a geological period about 444 million years ago. also see Ordovician-Silurian extinction events. see Related Link below
The Silurian period was between 443.7 - 416 million years ago, which means that it lasted around 27.7 million years.
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.
Considering that the silurian period is about marine life you would probably want to pack something that would allow you to live under water.

The 11 geological periods from Precambrian to Quaternary are :- Paleozoic Era Cambrian Period - 542 to 488.3 million years ago Ordovician Period - 488.3 to 443.7 Ma Silurian Period - 443.7 to 416 Ma Devonian Period - 416 to 359.2 Ma Carboniferous Period - 359.2 to 299 Ma Permian Period - 299 to 251 Ma Mesozoic Era Triassic Period - 251 to 199.6 Ma Jurassic Period - 199.6 to 145.5 Ma Cretaceous Period… Read More
Most Silurian land was part of Gondwana, a continent centered on the South Pole
The Silurian period started off with a mass extinction of 60% of all marine life. During the Silurian bony fishes evolved setting the stage for the Devonian, which is referred to as the "Age of the Fish".
Cambrian Ordovician Silurian Devonian Carboniferous Permian
Plants and animals finally emerged out of water onto land in this time period.
Silurian Period 408 - 438 Million Years Ago
The Paleozoic is an ERA which is made up of 6 periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. Over this 291 million year period, there was a great diversity in fungi, plants, and animals. The first half was dominated by marine algae, plants, fish, tetrapods, and insects. The second half of the Paleozoic era was dominated by reptiles and amphibians.
there was volcanic activity in every time period exept for the ones of water
Starting with the oldest, they are the: Cambrian, Ordivician, Silurian, Devonian, Carboniferous, and Permian.
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.
Trilobites and the first fish.
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.

The Amphibians evolved from a species of lobe-finned fish that emerge in the Silurian Period. Amphibians emerged in Carboniferious Period.
The life forms that lived during the Paleozoic are Permian, the Carboniferous, (both the Mississippian and the Pennsylvanian), the Devonian,the Silurian, the Ordovician, the Cambrian, and the Precambrian. The Paleozoic Era lasted from 570 to 225 Million Years Ago. Complex forms of life appear. During this 345 million year period, plants and animals underwent rapid evolution. The Paleozoic era lasted about 345 million years. It includes the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods… Read More
i actually dont know.
In the Silurian period, from about 430 - 420 mya
there were aracnids, jawed fish,eurypterid and land plant
Arthropods ( EARTH SCIENCE )
Corals were a dominate life form during the Silurian period because the climate was much warmer in the oceans and the ocean's were actually larger than they are today. This gave coral a chance to grow large and strong.
