This period was marked by an incredible increase in the number of plants and animals.
The oceans were populated by a multitude of species including the first animals to be equipped with eyes: the trilobites. The latter consisted of a segmented body and protected by a robust esoscheletro.I largest trilobites could reach 60 cm in length.
addition to trilobites, during this period, appeared and evolved even most of the invertebrates that inhabit our planet today, (including worms, sponges and molluscs), flanked by the first vertebrates, fish or Agnatha ("no jaw ").
If the oceans are populated by vast variety of animals and plants, we can not say the same thing for the land, which, in contrast, appear to be deserted and devoid of living organisms.
