Oxygen ranges on early Earth rose, fell a number of instances earlier than nice oxidation even
Earth’s oxygen ranges rose and fell greater than as soon as a whole lot of hundreds of thousands of years earlier than the planetwide success of the Nice Oxidation Occasion about 2.four billion years in the past, new analysis exhibits. … Continue reading
Primordial oceans had oxygen 250 million years earlier than the environment
New analysis has pushed a serious milestone within the evolution of Earth’s surroundings again by about 250 million years. Geology News — ScienceDaily
Cool idea: Magma held in ‘cold storage’ before giant volcano eruption
Long Valley, California, has long defined the ‘super-eruption.’ About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 cubic kilometers of lava and ash spewed out in the kind of volcanic cataclysm … Continue reading

Antibiotic-resistant microbes date back to 450 million years ago, well before the age of dinosaurs
Leading hospital ‘superbugs,’ known as the enterococci, arose from an ancestor that dates back 450 million years — about the time when animals were first crawling onto land (and well before the age of dinosaurs), according to a new study. … Continue reading

New indications of gradual decline of dinosaurs before the end of the cretaceous period
The gradual decline of the dinosaurs and pterosaurs presumably came before the impact of the Chicxulub asteroid and the global mass extinction at the end of the Cretaceous Period, new research suggests. Studies also indicate that bird species spread and … Continue reading
The Earth’s Crust Is Getting Thinner Than Ever Before
PAWEL TOCZYNSKI VIA GETTY IMAGES If you looked back at Earth 170 million years ago, you’d find a very different planet. The world’s continents were all linked up into one vast ‘supercontinent’ called Pangaea, and according to a new study, … Continue reading
Woolly mammoths experienced a genomic meltdown just before extinction
Dwindling populations created a ‘mutational meltdown’ in the genomes of the last woolly mammoths, which had survived on an isolated island until a few thousand years ago, report researchers. Paleontology News — ScienceDaily
Ancient rocks hold evidence for life before oxygen
This is a microscopic image of 2.5 billion-year-old sulfur-oxidizing bacterium. Somewhere between Earth’s creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen. While researchers proclaim the first half of … Continue reading
Ancient rocks hold evidence for life before oxygen
Somewhere between Earth’s creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen. The 2.52 billion-year-old sulfur-oxidizing bacteria are exceptionally large, spherical-shaped, smooth-walled microscopic structures much larger than most modern … Continue reading
