There are a few animals common to today's ocean whose relatives were also around 470 million years ago. Sharks are a good example.
470 million years ago was in the Ordovician Period (488.3 - 443.7 Ma).Phanerozoic Eon (542 Ma - Now)Paleozoic Era (542 - 251Ma)Ordovician Period (488.3 - 443.7Ma)Middle Ordovician Epoch (471.8 - 460.9Ma)Dapingian Age (471.8 - 468.1Ma)
The Taconic Mountains were uplifted approximately 440 million years ago during the Ordovician period.
Mosses first appeared around 470 million years ago during the Ordovician period. They were some of the earliest plants to colonize land.
The main groups of spider developed about 200 million years ago, in the Triassic period. Spider-like arachnids are known from towards 400 million years ago, and some true spiders are known from about 300 million years ago in the Carboniferous period. The spiders are part of the Arthropod family, which dates back to the Cambrian era, 500 - 600 million years ago.
None. The scorpion is an arthropod, and they existed long before the dinosaurs. Scorpions are anthorpods , they did not evolved from dinosaurs. They existed long before dinosaurs evolved. Its believed that scorpions existed in the Carboniferous Period (430 million years ago). Dinosaurs existed from the Triassic Period (230 million years ago) to the Cretaceous Period (65 million years ago).
1-1.8 million years ago was approximately 0.2-0.8 million years ago.
16 million years ago approximately
Scientists believe that trilobites reproduced sexually. These prehistoric and extinct creatures were a type of arthropod that probably laid eggs. Trilobites lived about 250 million years ago.
The Mesozoic Period (251 - 65 million years ago) lasted approximately 216 million years. It consisted of the Triassic Period (251 - 200 million years ago), the Jurassic Period (199-146 million years ago) and the Cretaceous Period (145 - 65 million years ago).
From about 180 million years ago until about 65 million years ago.
Pangaea formed about 300 million years ago and began to rift about 200 million years ago.The formation and falling apart of super continents appears to be cyclical. Pangaea is the fourth super continent in Earth's history.Known super continents:Columbia (2 billion years to 1.8 billion years ago)Rodinia (1.1 billion years ago to 750 million years ago)Pannotia (600 million years ago to 540 million years ago)Pangea (300 million years ago to 200 million years ago)
