🌎 Cosmogenic Krypton enables reconstruction of landscapes millions of years old
An international research team involving the #UniCologne has found a new way to reconstruct the development of landscapes millions of years ago. The researchers have discovered a rare noble gas called cosmogenic krypton, which provides insight into the residence time of sediments on the Earth's surface.

Researchers reconstruct landscapes that greeted the first humans in Australia around 65,000 years ago

Seventy thousand years ago, the sea level was much lower than today. Australia, along with New Guinea and Tasmania, formed a connected landmass known as Sahul. Around this time—approximately 65,000 years ago—the first humans arrived in Sahul, a place previously devoid of any hominin species.
