It is fossil fuels.
Natural gas is an eco-friendly and efficient energy source. It is formed when layers of buried plants and animals are exposed to extreme heat and pressure over a long period of time.
sedimentary rock
Both coal and oil are assumed to have formed from the remains of organisms that lived long ago. Most natural gas is also assumed to have formed by the decomposition of these materials.
The Carboniferous (Mississippian & Pennsylvanian) was not known for megafauna. There were some pretty big insects at that time. Diplovertebron reached lengths of nearly 2 feet. It was amphibious, dining on fish and smaller amphibians. Archaeothyris also reached lengths of nearly 2 feet, and was a synapsid (a precursor to modern mammals). From its teeth it is presumed to have been carnivorous.Edaphosaurus was a late carboniferous synapsid that lived into the Permian. It grew up to 12 feet long, but it was an herbivore, not a carnivore.The size and variety of carnivores increased substantially by the Permian.
It was when plants formed coal seam, crude oil and natural gas deposits. Any sedimentary rock formation, usually clay, sand or gravel, etc, would cause the layers to become compressed over a very long time, and the formation of our non-renewable energy to begin.
The Carboniferous is considered to have started 354 million years ago and ended 290 million years ago.
Pangea formed in the late Carboniferous about 300 million years ago.
Pangea formed in the late Carboniferous about 300 million years ago.
We do not know the exact answer, but scienctists approximate the late Carboniferous period; about 300 million years ago.
Coal is very old, it is believed to have been formed from plant matter that became buried in the Carboniferous Era, many millions of years ago.
Reptiles inhabited the earth before dinosaurs inhabited the earth. The first reptiles appear in the fossil record over 300 million years ago, in the Carboniferous period of the Paleozoic era.
The Pennsylvanian Period was from about 325 million to 280 million years ago. It is part of the Paleozoic Era. The Pennsylvanian and the Mississippian (345 to 325 MYA) are often grouped together as the Carboniferous Period.
The Carboniferous is considered to have started 354 million years ago and ended 290 million years ago.
Tetrapods (early amphibians) emerged in the fossil record some time int he lower Carboniferous, around 360 million years ago. Reptiles emerged later in the carboniferous, 320-310 million years ago, and were probably the dominant terrestrial fauna by the start of the Permian, 299 million years ago. If any period in geological history could be described as the age of the amphibians, it would be the lowere-to-middle Carboniferous.

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).
