Coal formation sucked so much CO2 out of the atmosphere that Earth nearly froze over 300 million years ago

“It is quite an irony that forming the coal that today is a major factor for dangerous global warming once almost lead to global glaciation,” the author said.

How coal is formed

Most coal formed approximately 300 million years ago from the remains of trees and other vegetation. These remains were trapped on the bottom of swamps, accumulating layer after layer and creating a dense material called peat. As this peat was buried more and more underground, the high temperatures and pressure transformed it into coal. Coal Formation Coal is still the

350-million-year-old former inhabitant of Gondwana found

A 350 million year old fossilized scorpion has become the world’s oldest known land animal to have ever walked the supercontinent Gondwana. Ancient history It’s 350 million years ago – take a moment to ponder that. Take a long human lifespan of 100 years, and multiply it by 100, and again by 100 – now you have a million years.

GeoPicture of the week: Giant Dragonfly fossil

This is a Cast of an original fossil of a Meganeuridae. If you’re scared of dragonflies, brace yourself for this: these extinct insects from the Carboniferous period measured up to 70 cm. They are the largest known species of flying insect. Controversy has prevailed as to how insects of the Carboniferous period were able to grow so large, especially considering

Ancient Fossilized Sea Creatures Yield Oldest Biomolecules Isolated Directly from a Fossil

Paleontologists have long believed that complex organic molecules couldn’t survive fossilization; but to contradict this long standing belief, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, feature exactly that type of molecules.   The animals in case are called crinoids, but are probably better known today as “sea lilies”; they are absolutely remarkable creatures, able to survive from

300 million year insects pictured in 3D

Researchers managed to construct a three dimensional (3D) portrait of two nymphs that inhabited our planet 305 million years ago by scanning their fossils with X-Rays. Old insects At the moment, they are by far the most detailed pictures of juvenile insects that inhabited that period; nymphs are the immature form of some invertebrates, particularly insects, which undergo gradual metamorphosis
