Question

During which period did eurypterids swim the oceans and the first jawed fish and vascular plants evolve?

Silurian period

Triassic period

Permian period

Answer 1

The correct answer is - Silurian period.

The eurypterids, initial jawed fish, and the vascular plants, are all supposed to have first evolved during the late Ordovician period, but in the fossil records they all start appearing in the Silurian period.

The Silurian period is a period in which there's enormous diversification in the animals and plants, with the bigger and more complex ones quickly developing and dominating the Earth. It is in this period that the ancestors of the later land animals appeared, though initially in the water, as well as the plants that covered the Earth and ever since than had been a key factor for the existence and development of the animals on the Earth.

The correct answer of the given question above is the first option. The period in which eurypterids swim the oceans and the first jawed fish and vascular plants evolve is in the Silurian Period. This is the period that occurred from 443 million to 416 million years ago and was the third period of the PaleOzoic Era. Hope this answer helps.
