In the era when the earth was born, what was the age before the age of dinosaurs?

Paleozoic: Are you asking about this? Before that, there were Archean and Proterozoic. What we usually call the age of dinosaurs is geologically known as the Mesozoic Era.

The Paleozoic Era (symbol PZ) is a generation in geological epoch that began with an isotopic age of 542 million years (MA) and ended in 251. The Paleozoic era belongs to the Phanerozoic, the previous era was the Neoproterozoic, and the next generation was the Mesozoic. The Paleozoic era includes the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.

The Devonian, Carboniferous, and Permian are also known as the Late Paleozoic.

Paleozoic Era – the third generation of geological time (the first generations are Archean and Proterozoic). It began about 100 million years ago and ended 100 million years ago. There are 6 periods in the Paleozoic Era, which are generally divided into Early and Late Paleozoic.

The Early Paleozoic Era included the Cambrian (Cambrian 100 million years ago), Ordovician (500 million years ago) and Silurian (100 million years ago), and the Late Paleozoic included the Devonian (Devonian 100 million years ago), Carboniferous (100 million years ago) and Permian (Permian billion years ago). The fauna is most abundant among marine invertebrates, trilobites, molluscs and echinoderms. In the Ordovician, Silurian period, Devonian and Carboniferous periods, lower fishes, paleoamphibians and paleoreptiles appeared one after another.

Fish reached their peak in the Devonian. Carboniferous and Permian insects and amphibians flourished. In the early Paleozoic, marine algae were the main species of ancient plants, and by the end of the Silurian period, primitive plants began to land on land.

The Devonian was dominated by gymnoferns. During the Carboniferous and Permian periods, ferns flourished in particular, forming dense forests, which were important coal-forming periods.

Jurassic Encyclopedia The Jurassic is a geological epoch between the Triassic and Cretaceous periods, from about 199.6 million years ago (with an error of 600,000 years) to 145.5 million years ago (with an error of 4 million years). So it should be Triassic.

After the extinction of the dinosaurs, before the advent of man, the ruler of the earth: birds and mammals.

Moa became extinct about 500 years ago and was once the overlord of the land, because more than 60 million years ago, the individual mammals at that time were not large, and most of them were burrowing, similar to rats.

The moa was once the largest of New Zealand's many birds, with an average height of 3 m, taller than today's ostriches. Feeds on terrestrial clump mammals.

Birds don't rule the earth for long.

Later, for some reason, the number of moa birds decreased and eventually became extinct, and in addition to the increase in the size of mammals, and the lack of many species is widely distributed and adaptable. Mammals subdued Zheng Shendai birds to become the new overlords on land.

And the overlords in the sky have always been carnivorous birds; The overlords of the ocean are the big predators, whales and sharks!
