The evolution of Ediacarans, some of the earliest complex life on Earth, could have been influenced by extreme cold and a giant asteroid impact which caused massive environmental stresses, says a new study. The Ediacarans are a weird bunch of organisms that included the world's first large-scale complex life. During the time they lived (635-542 million years ago) in southern Australia, the Earth experienced at least one cold snap that may have covered much of the Earth in ice. Read more
This image of the Acraman compex crater in South Australia was taken by the Terra satellite on the 18th February, 2010. The true-colour image shows Lake Acraman, Lake Gardiner and Lake Everard. The dotted white lines indicate the possible extent of the Acraman Impact Structure.
Acraman crater is a deeply eroded impact crater in the Gawler Ranges of South Australia. Its location is marked by Lake Acraman, a circular ephemeral playa lake about 20 km in diameter. The impact event is estimated to have occurred about 580 million years ago during the Ediacaran Period.
