USGS study finds new evidence of San Andreas Fault earthquakes
This Temblor map shows three of the sections of the Southern San Andreas Fault. This new study took place in the Big Bend section. The blue pin marks the approximate study site location. A new U.S. Geological Survey study offers … Continue reading
From rocks in Colorado, proof of a ‘chaotic photo voltaic system’
Plumbing a ninety million-yr-previous layer cake of sedimentary rock in Colorado, a workforce of scientists has discovered proof confirming a essential concept of how the planets in our photo voltaic system behave of their orbits across the solar. The discovering … Continue reading

Understanding new evidence of the impact of climate change in the Early Jurassic Period
This shows Early Jurassic ammonite. Credit: Plymouth University Geochemical and biological research offers academics a window into earth history, enabling them to piece together events that occurred before records began. Much of our understanding of past climate change is based … Continue reading
Evidence falls into place for once and future supercontinents
SUPERCONTINENT SUPERPUZZLE Supercontinents come and go over the ages. Amasia, illustrated here from the North Pole, might form in the distant future. Look at any map of the Atlantic Ocean, and you might feel the urge to slide South America … Continue reading

Fossilized evidence of a tumor in a 255-million-year-old mammal forerunner
An extinct mammal relative harbored a benign tumor made up of miniature, tooth-like structures, paleontologists report. The tumor, a compound odontoma, is common to mammals today. But this animal lived 255 million years ago, before mammals even existed. Paleontology News … Continue reading
Human ancestor ‘Lucy’ was a tree climber, new evidence suggests
Since the discovery of the fossil dubbed Lucy 42 years ago this month, paleontologists have debated whether the 3 million-year-old human ancestor spent all of her time walking on the ground or instead combined walking with frequent tree climbing. Paleontology … Continue reading
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
