During the middle silurian the climate was much warmer, it was though of as a period where the climate became more stable, ending the previous pattern of random climatic fluctuations. A new greenhouse phase began, leading to a rise in global sea level form ice melt. However, in coastal areas where there was warm shallow waters, the conditions led to large evaporite deposits, although this was largely exclusive to equatorial regions. In this instance, plants that had lived in water had to adapt to life on land or die off.

When did brontoscorpio live?
silurian period
What is silurian mean?
The Silurian period occurred from 443 million years ago until 416 million years ago. It saw the emergence of animals such as coral and fish that began quickly populating the oceans, and plants like the fern first appeared on the planet.
What was the environment like compared to the environment of the Silurian Period?
There were continents and oceans as we have them now but they were not in the positions they now there were probably just two , Gondwanda and Euramerica.During the Silurian, Gondwana made a slow southward drift to high southern latitudes, but there is evidence for Silurian icecaps Euramerica was located near the equator A vast ocean called Panthalassa covered most of the northern hemisphere. Other minor oceans include the Proto-Tethys and Paleo-Tethy, the Rheic Ocean, a seaway of the Iapetus Ocean and the newly formed Ural Ocean. During this period, the Earth entered a long warm greenhouse phase, and warm shallow seas covered much of the equatorial land masses. Early in the Silurian, glaciers retreated back into the South Pole until they almost disappeared in the middle of Silurian. The period witnessed a relative stabilization of the Earth's general climate, ending the previous pattern of erratic climatic fluctuations. Layers of broken shells (called coquina) provide strong evidence of a climate dominated by violent storms generated then as now by warm sea surfaces. The Silurian also saw the first extensive colonisation of the land by plants and we first period to see macrofossils of extensive terrestrial biota, in the form of moss forests along lakes and streams. Otherwise the land would have appeared bare of life.The first fossil records of vascular plants, that is, land plants with tissues that carry food, appeared in the second half of the Silurian period.
When did woody material in plants evolve?
In the Silurian Period, roughly 420-440 million years ago.
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.
Why are corals a dominant lifeforms on Earth during the Silurian period?
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.
Why were corals a dominant life-form during the silurian period?
fish
What was the evolutionary process during Silurian?
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".
What was the temperature like in degrees during the Silurian time period?
95 degrees
What dinosaurs were in the Silurian era?
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.
Which animals appeared for the fist time during the Silurian period?
Reef-building corals
What began to grow during Silurian period in damp areas on land?
simple plants.
Which animals appeared for the first time during the Silurian period?
Reef-building corals
During which period did eurypterids swim the oceans and the first jawed fish and vascular plants evolve?
Silurian period
During what period did the insects first appear?
Silurian Period 408 - 438 Million Years Ago
What organisms appearing during the Silurian period?
there were aracnids, jawed fish,eurypterid and land plant
During the Silurian period the first animals to adapt to life on land were?
Arthropods ( EARTH SCIENCE )
