The Paleozoic Era
Silurian
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.
The Ordovician period and the Silurian period
The Ordovician period and the Silurian period
The Ordovician period and the Silurian period
Starting with the oldest, they are the: Cambrian, Ordivician, Silurian, Devonian, Carboniferous, and Permian.
The first vascular plants appeared during the Silurian period, about 420 million years ago. These plants had specialized tissues that allowed them to transport water and nutrients throughout their bodies, which was a significant evolutionary advancement.
Nope -- way too old. Only primitive invertebrates and lower forms were around.
The Paleozoic Era Lasted about 2799. You can add all the numbers of the: Permian, Carboniferous, Devonian, Silurian, Ordovician, and the Cambrian. Add all of there numbers of how long each era lasted. So that's how long the Paleozoic Era Lasted ("2799")
Yes. The Mississippian period is a part of the Paleozoic era, along with the Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, and Permian periods.
The Paleozoic Era lasted from about 540 million years ago to about 280 million years ago. It included the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian Periods.
The Silurian period followed the Ordovician period.
