Ancestor of all animals identified in Australian fossils

Geologists have discovered the first ancestor on the family tree that contains most animals today, including humans. The wormlike creature, Ikaria wariootia, is the earliest bilaterian.

Earth's oldest asteroid strike linked to 'big thaw'

Scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia 2,2 billion years ago, and coincided with the end of a global deep freeze known as a Snowball Earth. 

Australian meteor crater is the oldest known crater on Earth

A NASA scientist analyzed the age of the Yarrabubba meteor crater in Australia and found it to be 2.229 billion years old, making it now the oldest crater currently known.

In death of dinosaurs, it was all about the asteroid

Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.

The Oldest Evidence of Life is Now Confirmed

The title of Earth’s Earliest Life has been returned to the fossils in the Pilbara region of Australia. A new study of the Pilbara fossils has identified the presence of preserved organic matter in those fossils.

Colossal flying dinosaur species discovered in Canada

Called the "frozen dragon of the north," a new species of flying dinosaur, Cryodrakon boreas, has been discovered in Canada. The pterosaur is thought to have had the wingspan of a small airplane.

Asteroid collision in space 466 mil years ago boosted life on Earth

Largest documented asteroid breakup in the asteroid belt during the past two billion years caused enormous amounts of dust to spread through the solar system. The blocking effect of this dust lead to cooler temperatures which in turn  caused diversification.

A face for Lucy's ancestor

Researchers have discovered a remarkably complete 3.8-million-year-old cranium of Australopithecus anamensis at Woranso-Mille in Ethiopia. Due to its rare state, the researchers identified never-before-seen facial features in the species.

1.2 billion years ago, a 1-km asteroid smashed into Scotland

New research by a team of UK scientists has located the site of the massive impact that took place in Scotland 1.2 billion years ago. Roughly one billion years ago, Earth experienced a higher rate of meteorite impact than it does today.

NASA Study Reproduces Origins of Life on Ocean Floor

A team of scientists has re-created some of the first steps of life in the lab, testing whether life could emerge on other ocean worlds.

Multicellular Life Began 1.5 Billion Years Earlier than Thought

The preservation of trace fossils, suggests that multicellular organisms that could move around to reach food resources may already have existed 2.1 billion years ago, more than 1.5 billion years older than previously thought.

Earth's Oldest Rock Found on the Moon

An international team of scientists found evidence that the rock was launched from Earth by a large impacting asteroid or comet. The impact sent material into space, where it collided with the surface of the Moon 4 bil years ago.

Oxygen could have been available to life as early as 3.5 billion years ago

Microbes could have performed oxygen-producing photosynthesis at least one billion years earlier in the history of the Earth than previously thought.

Massive impact crater discovered in Greenland

An international team has discovered a 31-km wide meteorite impact crater buried beneath the ice-sheet in the northern Greenland. This is the first time that a crater of any size has been found under one of Earth.

Lost Continents Hiding Under Antarctica

Antarctica was once part of the supercontinent Gondwana, which began to disintegrate some 130 million years ago, although the bond between Antarctica and Australia held together as recently as 55 million years ago.
