What is silurian mean?

Answer 1

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.

Answer 2

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.

Answer 3

Silurian plants were plants that lived about 443.7-416.0 million years ago.

This was the first time period which had an extensive terrestrial biota in the fossil record. Moss forests along lakes and streams were fairly common.

Answer 4

Mosses and other primitive plants grew over the land near the water's edge. They continued the work of the lichen by turning the rock into soil. There are a few fossils from the end of the Silurian Period that show us early insects lived among these mosses and made their own colonies. The soil made by the lichens grew strange plants called Cooksonia. These plants had stems, but no real leaves. Some Cooksonia had special tissues for carrying water and nutrients upward to the branching parts of the plant. This vascular tissue is common in modern plants, but was a first during the Silurian Period.

Answer 5

The Silurian was a time period 443 to 417 million years ago (mya). It was a time when the Earth underwent considerable changes that had important repercussions for the environment and life within it. The Silurian witnessed a relative stabilization of the earth's general climate, ending the previous pattern of erratic climatic fluctuations. One result of these changes was the melting of large glacial formations. This contributed to a substantial rise in the levels of the major seas. Coral reefs made their first appearance during this time, and the Silurian was also a remarkable time in the evolution of fishes. Not only does this time period mark the wide and rapid spread of jawless fish, but also the highly significant appearances of both the first known Freshwater Fish as well as the first fish with jaws. It is also at this time that our first good evidence of life on land is preserved, including relatives of Spiders and centipedes, and also the earliest fossils of vascular plants.

Answer 6

Plants during the Silurian period are of the genus Cooksonia. It was a branching stemmed plant that produced sporangia on their tips.

Answer 7

Yes, a workout with out cardio can still be a great excersice routine. You can do lots of non-cardio things like swimming, lifting wieghts, certain strecthes.
