# data[].attributes.body
The Solar System has been formed 4.5 Billion Years Ago, starting off from a dense cloud revolving with interstellar gas and dust at the same time.

# data[].attributes.body
Came at the same time during the Solar system's existence, Earth was formed in a gravity pulled through from swirling gas, and dust in to become the third planet in the solar system.

# data[].attributes.body
Being the first microscopic ocean animal to appear. As an example of this, cambrains were soft bodied animals with a shell or a caraspace.

# data[].attributes.body
The only oldest ice age to be known about, being the first. The cause of it would be lack of volcanic activity, speculated by scientists.

# data[].attributes.body
With the span of 41.6 Million years, Ordovician rocks have distinction of occuring the highest elevation on Earth, the top of Mount Everest.

# data[].attributes.body
The first set of insects appeared were evolving in marine or costal habitats and took to land.

# data[].attributes.body
The first set of plants had been resembled into cyanobacteria, modern algae, and lichens. Which is followed by bryphytes.

# data[].attributes.body
Continued on, volcanic activity and weathering related with extensive mountain structures causes the CO2 to melt, chilling the whole Snowball Earth to be gone.

# data[].attributes.body
With their appearance being jawless fish, they had a no cranium but no vertebral column.

# data[].attributes.body
This cause of the first extinction was cooling climates were being changed overtime in the ocean circulation pattern.

# data[].attributes.body
With the span of at least 24.6 Million years, this is considered the shortest period of the Paleozoic Era. Although it features the evolution and the diversification regarding of fish.

# data[].attributes.body
Spanning 60.3 Million Years, this period is notable for the spawning of a remarkable variety amount of fishes.

The Amphibians First Appearance, 390 MYA

# data[].attributes.body
The first sets of the Amphibians of their appearance, featuring had four sturdy limbs, a neck, a tail with fins and a skull.

# data[].attributes.body
In the late Devonian period, researchers came the conclusion that lead or other metal materials made deformities in the marine creatures. In which causes this extinction.

# data[].attributes.body
This ice age was named after the glacial tills in Karoo, while South African scientists think that the name was developed during the ice age.

Carboniferous: Pennyslvanian Period, 323 MYA

# data[].attributes.body
Being the shortest period of the Amphibians segment, with serving 25 Million Years. This period was known for the plant's material that's provided into extensive forests, resulting in a later formation of different aspects of material. An example of this would be coal for instance.

# data[].attributes.body
Dating back 315 MYA, the earliest reptiles known is referred to as a Hylonomus. Only apparently live in forested habitats.

# data[].attributes.body
The final period of the Paleozoic era. Serving 47 Million years, this period consists of Earth's crustal plates, formed into a single massive continent referred to as Pangaea.

# data[].attributes.body
By far one of the worst extinctions to ever occur. Formations of the giant continents in the Pangea caused a severe climate change in the environment.

# data[].attributes.body
What the title implies is this, is known for what for the first existence of dinosaurs on land. Although this serves 42 Million Years, a new era would be started along the line.

# data[].attributes.body
During the Triassic period, the fourth mass extinction occurred during the period. Pangea caused the volcanoes in the central Atlantic Magmatic Province. Causes global warming to start again.

# data[].attributes.body
Another well known period for it's time, with having 56 Million Years. This era consists of wet climate, lush vegetation for the life, and new different types of dinosaur species.

# data[].attributes.body
While having the oldest bird type up to date, being the Archaeopteryx. A range of birds with more advanced features appeared a lot sooner before the Archaeopteryx.

# data[].attributes.body
After occurring 5 different major events regarding the extinction, this is the last one to ever known. Causing the infamous dinosaur species to all be extinct.

# data[].attributes.body
The final, and the current Period we live in today. Many of the cycles glacial growth and retreat, with the exception of having many of the species like mammals, birds, and the first appearance of humans.

# data[].attributes.body
This is an ice age that we are still living in today's modern life, while also being the most recent to known. We are currently in an interglacial stage of this ice age.
