1-1.8 million years ago was approximately 0.2-0.8 million years ago.
The first land plants appeared around 450 million years ago during the Ordovician period. This marked a significant evolution in plant life, transitioning from aquatic environments to terrestrial habitats.
The ozone layer only formed about 600 million years ago when there was already a diverse array of life on Earth. Dinosaurs went extinct around 65 million years ago due to a combination of factors, such as a large asteroid impact and volcanic activity, rather than a lack of protection from the ozone layer.
The answer is 63.2 million years. Since the Tertiary Period began 65 million years ago and then stoped 1.8 million years ago you have to subtract the 1.8 million from 65 million to get the actual lenght of time.
The Paleozoic Era began about 541 million years ago and ended about 252 million years ago. It is known for the emergence and diversification of many marine invertebrates, the colonization of land by plants and insects, and the eventual rise of reptiles.
At the Chicxulub crater, which covers almost half of the Yucatan peninsula.
Dinosaurs dominated the land from 200 Million Years Ago to about 66-66 Million Years Ago.
65 million years ago the dinosaurs died out, presumably because of a massive meteorite.
65 million years ago. Nobody knows why they died but the main theories are a giant meteorite or the earth tilting on its axis making the world get cold.
pangea?
No. Actually, it is older than that: the Chicxulub crater in the Yucatan Peninsula is the most probable site where the meteorite that killed the dinosaurs crashed some 65 million years ago.
350 million years ago
pangaea
Around 1,200 Million years ago but it wasn't until around 450 million years ago land plants formed.
Yes. It is the Chicxsulub crater, partially touching both the Gulf of Mexico and the Yucatan Peninsula. It is the place where the meteorite that wiped out the dinosaurs crashed, some 65 million years ago.
1-1.8 million years ago was approximately 0.2-0.8 million years ago.
Plants in the sea evolved about 3,600 million years ago. The first algal scum on land about 1,200 million years ago, The first first land plants appeared around 450 million years ago in the Ordovician period.
