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.
What else can I help you with?
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 carboniferous environment like compared to the present?
During the Carboniferous period, the environment was warm and humid, with vast swamp forests covering much of the land. These forests eventually formed the coal deposits we see today. In contrast, the present environment is cooler and drier overall, with different vegetation and ecosystems in place.
What period of history do scientists think jaws developed?
Scientists believe that jaws likely developed during the Silurian period, around 430 million years ago, from modifications of the anterior gill arches of early fish-like organisms. This evolutionary development allowed for more efficient feeding and predation, leading to the diversification and success of jawed vertebrates.
Dangers in the silurian period?
You may face troubles with the organisms, for the sea life was then dominant... but most likely it would just be the humidity of the time, and the dominant, or dangerous organisms during the time.
How do penguins smell?
Penguins have a weak sense of smell compared to other animals. They rely more on their vision and hearing to navigate their environment and find food.
How was the environment like during the Cretaceous period compared to the present?
grassy and naked
What was the temperature like in degrees during the Silurian time period?
95 degrees
What was the environment like compared to the present carboniferous?
the carboniferous period had crinoids,echinoderms but today we don't have it
What did the earths surface look like during the silurian period?
Type your answer here... it was wet and the surface was covered with a thin layer of warm water.
What was the devoinan period environment like?
The environment in the tertiary period was mostly covered with trees and grass.
What is the environment like in the Jurassic period compared to the present?
During the Jurassic period, the environment was warmer and had higher levels of carbon dioxide in the atmosphere compared to the present. The landmasses were generally located closer together, forming the supercontinent Pangaea. The Jurassic period had a diverse range of plant and animal species, including dinosaurs, which dominated the terrestrial ecosystems.
What was the environment like in the cretaceous compared to today?
the environment during the cretaceous period was warm with ice-free poles. Back then, there were mostly dinosaurs roaming the earth, but other mammals we see today were starting to appear.
